Incognito introduces Prima Rebus™ screed for timber joisted first floors

Incognito introduces Prima Rebus™ screed for timber joisted first floors

The use of engineered joists is increasingly common in house construction. These provide challenges for the Underfloor Heating designer and fitter alike, as traditional installation methods must be adapted, resulting in increased costs and install times. As a result some contractors view radiators as a comfortable trade-off on upper floors. In response Incognito Heat Co. has developed the Prima Rebus™ system that overcomes these issues, and installation is carried out both quickly and safely.

Prima Rebus™ High quality floor screed for timber joisted structures.

Prima Rebus™  is a liquid pumpable self-compacting screed system with additional binders and additives which has been developed for use on timber joisted structures. The binders content means screed can be laid to depths as low as 40mm, critically reducing the weight load on supporting structure.

This means that that screeded underfloor heating systems are now doable on upper floors, where traditionally it has not been considered possible.    

When considering using this system, it is critical to ensure that supporting timber structure has been designed to accommodate the increased weight that is associated with the screed.

Incognito Heat Co work closely with architects and structural engineers prior to plans being submitted for building warrant to ensure this system is seamlessly designed in the fabric of the buildings super structure.

The system offers all the benefits of the cliprail system normally employed on a solid floor, on a timber supported floor. The cliprail system is one of the most common underfloor heating systems providing a quick, flexible and effective form of heating within a screeded floor build up. A 500 gauge polythene slip membrane is installed across the floor prior to fitting cliprails. Once the cliprails are secured in position, the underfloor heating pipework is laid in continuous loops and clipped down in accordance with the underfloor heating design drawings. Once complete, the system is pressure tested and witnessed to finalise the installation. Screeding follows quickly afterwards, which may be as thin as 40mm.

Incognito Heat Co. Prima Rebus™ is suitable for use over the underfloor heating system.  PR screed is suited to both residential and commercial properties, and will help to improve the acoustic performance of the floor to meet or exceed Part E of the building regulations. Prima Rebus™ screed also improves the environmental, fire resistance and durability characteristics and gives a concrete feel to a timber supported floor. This system provides increased efficiency and maximises the Temperature Star Rating potential for clients installing ground and air source heat pumps.

Underfloor Heating Cumbria

Underfloor Heating Cumbria

Underfloor Heating Cumbria is on the up, not least because Cumbria homes decided to add underfloor heating as an option to the homes at Carleton Manor Park in Penrith and as standard to the apartments in the Manor House. Incognito Heat Co are responsible for the design, supply and installation of the underfloor heating and floor screeds throughout the houses on this site. Cumbrian Homes developments can be found throughout Cumbria from the tranquil Eden Valley to historic Carlisle and here in Carleton, Penrith, on the edge of the beautiful Lake District National Park.  

Underfloor Heating Lake District Cumbria

Cumbrian Homes are no ordinary house builders in the Lake district, they believe that their clients should get to choose exactly what they want, and are proud of their “going the extra mile, customer led service.

Incognito Heat Co were delighted to have been chosen as Cumbrian Homes trusted underfloor heating and floor screeding specialist’s to carry out works when clients have selected underfloor heating, which is offered on this site as a luxury upgrade from the more traditional radiator heating systems.

Incognito Heat Co feel the same way about customer service, and are delighted that the majority of clients to purchase houses on this site have chosen our state of art underfloor heating systems for their homes in the Lake District in Cumbria.

Using our state of art rapid curing liquid floor screed over the underfloor heating systems means floors can be ready for their final covering (tiles, engineered timber, amtico or carpet) within 21 days of initial installation date. This is a drastic improvement on the more commonly used Anhydrite alternative which can take as long as 80 days plus (causing major headaches if you have a tight deadline to meet).

Cemfloor is a specially formulated polymer modified binder product that is used to create self-levelling, cementitious floor screeds.

Incognito Heat Co adopted this new screed material as soon as it was commercially available here in the UK in early 2017, and we’ve kept on having delighted customers ever since (including Cumbrian Homes) .

Not only does it give developers the very practical onsite benefits with the speed / quality of installation, and curing times.

It’s also a perfect match for our underfloor heating systems with its superior thermal conductivity, meaning heating systems are more reactive, and less costly to run. So it was an easy and exciting decision for Incognito Heat Co to switch to this new innovative material as soon as the benefits to developers and end users were apparent.

Energy efficient home in East Lothian

Energy efficient home in East Lothian

When Mr & Mrs Robertson purchased the plot for their energy efficient home home in East Lothian, it wasn’t in their mind to buy the house next door as well! However as it solved many difficulties the neighbouring property was duly acquired and the project got underway. Living next door to the site did at least mean that the build progress could be monitored on a daily basis, as well as overseeing the general security of the site.

Energy efficient home in East Lothian

From initial sketches by Edinburgh based Camerons Architects grew the designs for a modern, super insulated, energy efficient home. Incognito Heat Co. was involved in the initial discussions with the architects to provide the heating and hot water solution. With involvement at such an early stage we were able to ensure that build methods favoured the installation of an air source heat pump.

Upper floor underfloor heating

Underfloor heating was the favoured method of heating for this East Lothian energy efficient home, for both the client and the architect. Conventionally underfloor heating is installed on ground floors; whilst wall mounted radiators are used upstairs only due to the perceived difficulties of UFH installation within a timber floor. We were keen to use underfloor heating on both floors as it can improve the efficiency of the heat pump. It was decided that the mid floor construction would be engineered for the weight of a screed allowing us to incorporate pipework easily and safely onto a timber deck.

Manufactured joists were used throughout the mid floor construction. These are lightweight alternatives to traditional solid timber joists. They save weight and natural resources whilst giving great flexibility for other trades to pass services, ducts and cables through their open web structure. The upper and lower flanges must not be cut to preserve the structural integrity of the joist, which prevents the installation of underfloor heating within the profile of the floor- in the event this isn’t such an issue as the floor is normally sheeted immediately. This stiffens the entire structure by tying each joist to another, and provides a safe working platform for all other trades.

There are compelling environmental reasons for using screed on upper floors, as well as improving the fire resistance and durability of the floor. A major component of the screed is an inert by-product of an industrial process, thus increasing the recycled content of the property. Using locally sourced aggregates and UK produced binders, (there is no cement used) there is low embodied energy in the product.

By embedding the UFH pipes in a screed it is possible to operate the heating at a lower temperature. This is most significant for the operating efficiencies of the heat pump, as less energy has to be expended to maintain comfortable temperatures within this energy efficient East Lothian home. Since the introduction of the Energy-related Products Directive, every heat pump manufacturer must provide data on the energy performance of their equipment at various temperature outputs. It is now very easy to see the impact that build method, heat emitter selection and floor coverings can have on ongoing efficiencies and therefore running costs.

Technical installation

Moving outside, the chosen air source heat pump was a 12kw unit from NIBE. This is an excellent example of Scandinavian engineering, NIBE are a company with a long proven track record in manufacturing quality renewable products. The installation was carried out under the NIBE VIP Installer scheme, the client benefitting from a seven year warranty.

NIBE heat pump

Inside the quality continues, with a 300 litre domestic hot water cylinder installed to provide plentiful hot water to the property's bathroom and three Ensuites. Early in the design process we discussed the clients’ requirements for hot water to ensure the demands of the household would be met at peak times. For properties where particularly heavy usage is envisaged we will provide larger volumes of hot water storage to suit, together with an indication of the additional energy that will be required to heat this.

A third party MVHR system (Mechanical Ventilation Heat Recovery) was installed. This extracts warm, stale air from wet areas such as kitchens, bathrooms and Ensuites. The air passes through an MVHR unit to extract the energy, the stale air is vented outside whilst the captured energy is transferred to incoming fresh air and ducted to living areas. A big benefit of this is a reduction in energy lost via air changes, further increasing the efficiencies of the heating system. Additionally, a 4Kw solar panel system was installed to further the energy efficiency of this East Lothian Home.

The build project was carried out by Lawrie Construction. Incognito Heat Co. worked closely with Lawrie Construction to coordinate fitting the underfloor heating and screed, the air source heat pump and DHW cylinders were fitted in compliance with current MCS standards.

"If it's good don't touch it!" is the general saying, just like something along the lines of: "Never change a winning team!" and "If it ain't broke, don't fix it!". All very true, but hanging on to something too long may restrict progress and after all, here at Incognito Underfloor Heating, it is all about progress and change, otherwise we would be a coal-merchant or selling stoves!

 The 'old' logo and the 'new' logo 

The 'old' logo and the 'new' logo 

Renewable energy sources in combination with underfloor heating was the future 10 years ago and still is today. In spite of the growth that Incognito has seen over the years, there is still a long way to go to before we all benefit from green energy and the comfort of underfloor heating. So we are not quite done yet!

It was therefore only appropriate to change our corporate image in accordance with what they call in marketing terms: 'within the just noticeable difference'. Hence the need to write about it in this little news blog, just in case you might have missed it...?

The unseen world of Incognito Underfloor Heating


The unseen world of Incognito Underfloor Heating

A little introduction to this blog

Last Monday our Sales Director Andrew Skirton won the blog competition for Incognito in the class 'website worthy'. Every now and then we call a staff competition and this time it was blogging. The Marketing Manager thought that this was a great idea to get some, as he calls it, 'unique quality content', for the website. You can decide yourself if he succeeded in that..

Lets introduce the author of the article below to you first:

Portrait of Andrew Skirton drawn by a colleague in an earlier staff competition

Not sure if you have met the fellow yet but he talks just the way he writes, so here it comes:

The unseen world of Incognito Underfloor Heating

So what exactly are you on about? What do you do? How does it work? What’s so good about it? Does anyone even care? Does anyone actually want it?

In my darker moments, (do you ever get those?) the latter question pushes through my mind; it shouldn’t of course, because I absolutely believe it’s the way forward, the future, the way to go, a no brainer if you prefer.

I’m talking about our product, which is of course the best of the best, extraordinary in its simplicity, brilliant in it execution, delivering exactly what it’s designed to do, quietly, efficiently, with no fuss or excitement. In fact, you’d hardly know it was even there.

So it’s out of sight and out of mind, and easy to take for granted. However you’d certainly notice it, if for any reason it wasn’t working:)

In todays increasingly hard to please, crowded and challenging market places, where excitement thresholds are at an all time high, what is this thing? And why is it so good? And if it really is that good, why isn’t everyone using it?

Underfloor Heating Glasgow

Well it’s not particularly new. The Romans actually left us examples of underfloor heating North of Glasgow, when they were over here in Britain some 2000 plus years ago, it obviously worked well for them, and it’s widely accepted that they (the Romans) were smart people, in many ways ahead of their time with their engineering excellence.

Roman regimental bath house with underfloor heating Glasgow

Bearsden's Roman Baths (by the way did you know that Andrew is originally from Bath?!)

Air heated by two furnaces passed beneath raised floors. (Bearsden north of Glasgow)

It’s 30 percent more efficient than its more traditional alternative (come on, that’s good) are you with me?

It’s safer (again that’s good,) please do try and keep up. It works extremely well with green renewable energy (yep, that’s good as well) your catching on now, well done. It does not obstruct your interior design ideals (unlike a certain more traditional method). In short, it’s really good.

So what am I talking about? And can I justify my claims? Let me explain:

I am of course referring to “UNDERFLOOR HEATING”. Actually to be honest, explicitly, INCOGNITO HEAT CO, UNDERFLOOR HEATING.

A few fizzy facts to consider which back up my lofty claims:


Underfloor heating uses the whole floor as a heat emitter, effectively turning it (the floor) into a giant radiator, typically meaning your boiler only needs to produce a flow temperature of 35 / 45 degrees to create comfort conditions. Traditionally a boiler would need to deliver 70 plus degrees for a conventional radiator system to create similar temperature levels (notice I didn’t mention comfort conditions?) That’s because an underfloor heating system delivers superior comfort conditions at lower temperatures due to its even all room no cold spots coverage.

So you don’t need to be Albert Einstein to work out that it will produce the very best comfort conditions, at significantly lower running costs in comparison to a traditional radiator system.


Let’s face it; radiators are a safety hazard which we accept just because they have always been there. But consider the cold hard facts; a radiator is a protruding oblong metal panel, with harsh edges which is normally attached to at least one of the main walls in every room of your house. When you consider that these radiators will often be too hot to touch, you can appreciate that these traditional (much loved) heat sources are in fact a very real safety hazard to all of us, but especially the very young, disabled and the old and infirm.

Renewable energy

Typically, a renewable energy ground or air source heat pump will work most efficiently when asked to produce a flow temperature of between 35 and 45 degrees, this is absolutely perfect for underfloor heating. Again, no need to consult Mr Einstein about this one, even you and I can work this out.

Interior Design

Rest easy Mr Einstein, we can work this one out for ourselves as well. With no radiators cluttering up our wall space, we can place furniture just wherever we want. Wow, that’s not bad, never realised this was an option.

Okay, I think that enough pontificating from me on the technical benefits.

So why Incognito Heat Co, who are they? How long have they been there? Where do they ply their trade? And are they the right people to consult before embarking on that exciting new house build or refurbishment?

Our head office is in Falkirk central Scotland, and from this base we operate throughout Scotland, and the north of England, with current sites ranging from Aberdeenshire, Central Scotland, the Boarders, the North East, Penrith and the Lake District. We’ve been here since 2005, and are planning to be here for many years to come (so get use to it).

Finally, are we the right people to speak to? The answer is of course a resounding “ABSOLUTLEY” Sustainable Heating is our passion, we love it. The other thing we love is complete customer satisfaction.

We have a great team, we are friendly, committed, knowledgeable, easy to work with, come on, pick up the phone and speak to one of our experts today, let start on this exciting journey!

There is more, much more, I haven’t even mentioned our floor screeds or renewable energy division yet, but and time is running out and this blog to already too long so I will leave on this final note, our people.

By far the most important component of our business, the reason we succeed, our people, we would be nowhere without them.

As the great Scottish American industrialist Andrew Carnegie once quoted “Take away my people, but leave my factories and soon grass will grow on the factory floors......Take away my factories, but leave my people and soon we will have a new and better factory." 

I will close on that inspiring note, on another day, another blog; I will do proper justice to the people who make it all happen for us.

So did he succeed?

And what do you think? We thoroughly enjoyed reading this, but we are biased because we know Andrew. So we are very much looking forward to your comments!











Quick drying screed

Quick drying screed

It is a boast of ours that we are completely indifferent about the heat source that connects to our underfloor heating...well, when it is not one of our heat-pumps, that is. But apart from that if it produces hot water, you can connect it to one of our systems, however we do like to know what that heat source is before we start designing. If for example the heat source has a low flow temperature, we will design the system differently to a system that has a higher flow temperature. To date we can list conventional gas and oil boilers, electric boilers, ground and air source heat pumps, biomass boilers, hybrids and even AGA and Rayburn style range ovens among the appliances we connect with.

Renewable Energy

For our clients we can offer combined pump/blending valves (the most popular configuration for conventional heat sources), in-line blending valves and bare manifolds if the heat source has sufficient pump capacity. On this renewable energy project our client has fitted a Windhager pellet burning boiler, combined with an evacuated tube solar thermal roof mounted system.

Temperatures from this system therefore will potentially exceed what is regarded as the safe limit for floors, so it was necessary to incorporate a means of tempering the flow from the boiler. As the integral pump within the Windhager pellet boiler was powerful enough for the underfloor heating system, a three port blending valve was supplied. This takes water from the boiler into one port, another port takes water returning from the underfloor heating system (therefore cooler) and the resulting mix is fed to the underfloor circuits.

Quick drying screed

We were contracted to provide the underfloor heating and the screed over the pipes. The depth of screed is typically around 50-60mm. Traditionally a sand/cement screed will be laid to 65-75mm, this operation is quite labour intensive and the results we are sad to say, are only as good as the screeder doing the work. Among the advantages of flowing screed is the speed of application, 300m² to 500m² per day is easily achievable, an area that couldn’t be countenanced by manually applied methods. Access issues are overcome too, as we frequently find when confronted with difficult sites. With hoses extendable up to 100m there aren’t many places we can’t reach.

Fluidity checks

It was just before we started the project that we learned of a potential problem- the client was moving in within a very short timescale, the screed needed to be dried within an impossibly short time! Fortunately for all concerned, a high performance cement based screed has been developed, our project was among the first in Scotland to receive it. Its exact composition remains a trade secret for the moment, but you can expect to see more of this remarkable material in the future. The screed behaves exactly as we would expect a flowing product to do, but most remarkably it will be ready for tiling within half the time of any other comparable material. The product is batched at the concrete plant, ensuring strict quality control is maintained; further checks on the fluidity of the material are carried out on site prior to discharge.

It all comes together

The project was completed without hitch, the underfloor heating installation was carried out in a neat and tidy fashion (some might argue that out of sight is out of mind- but our fitters would disagree) and screed was timed for the day after the UFH was finished. As the site was in a mid terrace location there was little scope to lose surplus material, a site survey was carried out to confirm the quantities required. The screed team protected the immediate vicinity against concrete splashes, and there was minimal disturbance for the neighbours. We worked closely with the installers of the bio mass system and the electricians and plumber on the project, and the client was kept informed about progress at each stage.

Underfloor Heating Artpark Glasgow

Underfloor Heating Artpark Glasgow

The new Studio Pavilion at House for an Art Lover with underfloor heating in Glasgow is an important addition to the existing facilities at this cultural centre. The building is set within Glasgow’s leafy Bellahouston Park, attached to the Victorian Walled Garden, and provides flexible space for a wide range of activities.

Underfloor Heating Glasgow

The Pavilion building offers around 80m² of studio space. Large amounts of glazing in walls and from its distinctive roof profile flood the room with natural light. Smaller offices and W.C’s flank the main studio, and a small plant room houses the equipment required by the underfloor heating Glasgow system.

Underfloor Heating Glasgow

The entire building is heated by Ambiente PE-RT pipework fitted to steel reinforcing bars within a concrete slab. The pipe is of extremely robust manufacture, made up of 5 layers including an oxygen barrier. As many installers will confirm, the pipe is very flexible and easy to use, even at low outside temperatures.

An air source heat pump was installed to provide space heating to this building. The efficiency of a heat pump is greatly enhanced when the flow temperature is low, and we achieved this by installing the underfloor heating pipe at 150mm centres throughout.

Underfloor heating Glasgow

By carrying out the installation of the Underfloor Heating Glasgow at such an early stage in the construction process, a temporary manifold board had to be constructed.  This allowed the manifold to be suspended at the correct height, until the wall was constructed that would eventually carry it. A 90⁰ bend is fitted onto each UFH ‘tail’ to bring the pipes out neatly from the floor. Pipework was pressurised and held under test whilst the concrete was being poured and finished.

Electrical floor boxes are installed in the slab, and we coordinated our pipework with the site electricians to avoid conflict with the conduit feeding these outlets. In keeping with the slightly ‘industrial’ feel of the building no additional floor finish was intended, and the bare concrete was lightly polished and sealed. Whilst the decision to use a concrete finish was based on aesthetics, it also meant that heat passes through the slab met with very little resistance, further improving efficiencies.

Underfloor Heating Glasgow

A Panasonic heat pump was installed, one of the smallest three phase units on the market. Mounted to the rear of the building, the external unit takes low grade energy from the surrounding air, and by a process of refrigeration delivers high grade heat into the building. With space in the plant room at such a premium, we opted to supply a wall mounted buffer tank. The purpose of a buffer tank is to increase the capacity of the heating system and prevent short cycling of the heat pump. We supplied a 100 litre vessel, and mounted this on a wall thus freeing up valuable space below.

To maintain clean lines throughout the studio we supplied a button sensor. This allowed the thermostats to be installed within staff only areas whilst registering the temperature in the public areas. These button sensors are very discreet and can be concealed if necessary.

Renewable Heat Incentive scheme further improved!

Renewable Heat Incentive scheme further improved!

The Renewable Heat Incentive (RHI) was introduced to help kick-start the transition to low-carbon heating in the UK, giving help to all in moving from conventional forms of heating to low-carbon alternatives. The scheme provides financial incentives to households and non domestic consumers, including public bodies and charities. It is designed to help bridge the gap between the cost of renewable heating systems and those of conventional alternatives. People who join the scheme and stick to its rules receive quarterly payments for seven years for the amount of clean and green renewable heat their system produces.

Since opening in April 2014, the scheme has already seen thousands of people successfully join and receive payments. That is why the Government is reforming the scheme to ensure it focusses on long-term decarbonisation. It made a number of adjustments as a result of a recent consultation process. The consultation proposed several changes to the existing domestic RHI scheme. Below is a summary of the UK Government’s final proposals in relation to the scheme, which the UK Government intends to implement in spring 2017.

·         The scheme will continue to support all four technologies currently supported, i.e. Biomass, Solar, Air source and Ground source heat pumps 

·         The tariffs for new ASHPs (air source heat pumps) will be increased to 10.02 pence per kilowatt-hour (p/kWh).

·         The tariffs for new GSHPs (ground source heat pumps Scotland) will be increased to 19.55p/kWh.

·         The tariff for new biomass installations will be increased to 6.44p/kWh, the level available between October and December 2015

·         The increased tariff for biomass boilers and stoves, ASHPs and GSHPs will be applicable to those participants who apply to the scheme on or after 14 December 2016 (the date the consultation response was published) although the increased tariffs will only apply from the date the regulations come into force. Participants will receive the existing tariffs for heat used (on the basis of either deeming or metering) before this point. This approach is intended to encourage consumers to continue to install renewable heating systems between the date of the consultation response and the date the changes come into force, to avoid a hiatus in investment and consequential impacts on the supply chain.

·         Heat demand limits will be introduced, to limit the level of annual heat demand in respect of which any household can receive support. The heat demand limits will be set at 20,000kWh for ASHPs, 25,000kWh for biomass boilers and stoves and 30,000kWh for GSHPs. However, this will not disqualify properties with higher heat demands from applying to the scheme. There will be no heat demand limit for solar thermal.

·         All new ASHPs and GSHPs applying for support under the scheme will be required to have electricity metering to monitor their heating system. However, payments will continue to be on the basis of the deemed heating requirements of the property, except for second homes and where a renewable heating system is installed alongside another heating system, in which cases payments will continue to be on the basis of heat metering.

·         GSHPs making use of a shared ground loop will continue to be eligible for the non-domestic scheme and will not be eligible on the domestic.

Underfloor Heating Forth Valley Scotland

Underfloor Heating Forth Valley Scotland

For these dog lovers, Underfloor Heating made perfect sense in their self build project in Larbert, Scotland. With large glazed areas overlooking the picturesque Forth Valley, Underfloor Heating was particularly appropriate, the floor turning into a large scale heat emitter more than compensating for the loss of wall space. Interior space planning becomes a doddle when there are no obstructions on the walls.

Underfloor Heating Forth Valley Scotland

The homeowners wanted the look of a timber floor in their hallway but didn’t want their home feeling too ‘woody’- and were delighted when they found ceramic tiles that looked exactly like wood! Now they combine the attraction of a timber floor with the hardwearing practicality of a ceramic floor- and the dog enjoys it too!

Each zone is controlled by a dedicated programmable thermostat. This ensures that the rooms are always warm during the occupied periods, and are set back by a few degrees when the homeowners are away. Realistically it is unlikely that a modern well insulated house would lose 4⁰C over the course of a day, but if it ever did (remember the winters of ‘09 and ‘10?) the heating would automatically kick in.

On the upper floor radiators were installed. These are connected to a manifold so that each room can be independently (and accurately) controlled for time and temperature. Let’s face it, thermostatic radiator valves were good and a giant leap forward when they first came out in the 1970’s. Unfortunately, as most homeowners now appreciate, the timeclock will always bring the boiler on, regardless of whether heat is required or not. Now with our system the boiler will only be activated if there is a need for it.

Not everyone enjoys thermostat programming or even understands how to use them, so there was a certain amount of trepidation when we started to demonstrate how to use the Underfloor Heating controls. However, once we got started and downloaded the NEO app onto the homeowners’ tablet, all those worries evaporated. Earlier networkable systems required a computer technician or a six year old to set up, not with this system! Whilst the system will work from anywhere in the world whilst you have an internet connection, and arguably this is what it was designed for, it is also just as easy to increase the temperature of the upstairs bathroom whilst lounging in front of the TV downstairs.

Underfloor heating Edinburgh townhouse

Underfloor heating Edinburgh townhouse

Working within the constraints of a listed building will be a very familiar situation for builders operating in the city of Edinburgh. Having successfully worked in a number of prestigious Edinburgh townhouses in the past, we were asked by a specialist building contractor to provide an underfloor heating solution for a large terraced property in the New Town.

Underfloor heating Edinburgh townhouse

Underfloor heating in a townhouse in Stockbridge Edinburgh

Each level of the property was to be heated with underfloor heating; no increase of floor height would be acceptable, and a mix of solid and suspended timber floors was going to be encountered between the basement and ground floors.

At basement level the existing floor was excavated during the project, which allowed for insulation to be fitted. The AmbiTak system was employed throughout this level, pipework was secured to the insulation using barbed staples. Pipework followed the ‘snail’ pattern ensuring an even spread of warmth across the floor.

Construction works in the Centre of Edinburgh

We are very conscious of the need to keep the environment clean when we carry out our screed pours. Luckily the property still retained the coach house with access to the lane behind. From this point we were able to set up our screed pump and run hoses into the basement. Taxing the patience of Edinburgh’s traffic attendants, we were able to pump six and a half cubes of anhydrite screed in just a few minutes, had a traditional sand/cement screed been applied this process would have taken many times longer.

The screed is a mix of sand, binders and clean water. It is a cement free product, therefore much easier on the environment. As it is liquid when applied, the screed can envelope the pipework, increasing the surface area to emit heat into the floor. Laboratory tests indicate that anhydrite floors warm up 30% faster than sand/cement floors as a result.

Elsewhere in the property we encountered joists- serious pieces of timber! The existing floorboards were lifted to expose the joists; typically these were centred at 18” (give or take a bit.) To cope with the slightly wider joist centres, aluminium heat diffusing plates were manufactured to suit. This reduced the need to carry out additional joinery work in getting the plates to fit.

As underfloor heating manifolds would look out of place in such an environment we went to great lengths to ensure these were concealed, but still accessible. When the manifold for the ground floor proved too long for its intended housing we provided two shorter ones stacked one above the other.

Underfloor heating combined with cast iron radiators in Edinburgh

Underfloor heating combined with cast iron radiators

On each landing throughout the property beautiful cast iron radiators have been installed- these have been connected into the same manifolds as the underfloor heating. We supply 15mm adaptors to take industry standard plumbing pipe; each radiator in the property can be controlled individually, preventing the wasteful habit of heating the whole house when only part of the house is occupied.

The whole project has been a great example of a 19th Century property with an infusion of 21st Century technology. Each zone is controlled by its own NEST thermostat, allowing the homeowner to monitor and adjust the temperature from their smart phone or tablet, from anywhere in the world.
