The most common heating sources have for a long time been non-renewable fossil fuels and electrical energy. High energy prices and the increasing interest in the reduction of carbon emissions are boosting the market for renewable energy sources such as heat pumps in Scotland. Tomorrow's heating technique is available today.
Heat pumps have been a common feature in the Nordic regions of Europe for many years and Glasgow had one of the first Underfloor Heating systems at the Bearsden's Roman Baths. A heat pump provides an economical and environmentally friendly method of heating. It makes you independent, it cuts down your heating costs and it is high technological and almost totally maintenance free.
Incognito Heat Pumps Scotland work by extracting an inexhaustible free supply of solar energy stored naturally either in the ground, air or water and utilising it for domestic underfloor heating and hot water.

In order to access this free environmental supply an energy input is required. In a well insulated property, every 1 kilowatt of electricity used to power the heat pump can provide up to 4 kilowatts of free energy.
Heat Pumps Scotland are simple, well-proven machines that can provide your entire central heating and hot water requirements. With fewer moving parts to go wrong, heat pumps have a life expectancy of over 25 years, and with no annual service or maintenance required, ongoing costs can be reduced by as much as 75%.
The basic principle of a heat pump is to take low-grade heat from the ground, and convert it to high-grade heat for your house using refrigeration technology. For every 1kW of electricity consumed by the heat pump, over 4kW of heating can be supplied to your home.

The basic operation of a ground source heat pump is as follows:
A few feet below the surface, the earth in your garden remains at a constant temperature all year round. Heat pump technology simply extracts this free energy. The seemingly low ambient temperatures are enough for a ground source heat pump (or geothermal heat pump) to heat your home.
The compressor, which is driven by an electric motor, compresses the refrigerant to form a high temperature, high-pressure gas. This gas then passes into the condenser (plate heat exchanger). The water from the radiator system is also pumped through the condenser where the heat is transferred from the refrigerant to the radiator water. As a result the refrigerant is cooled and condenses, changing state from a gas to a liquid.
After the condenser, the refrigerant passes through an expansion valve, which rapidly drops the pressure, and therefore lowering the boiling point of the liquid.
In the evaporator, the refrigerant takes up heat from the water/glycol mix that is circulating in the ground loop and boils. In this process, the liquid turns to gas and returns to the compressor to begin the cycle again. This in turn makes the ground loop water cooler that is then pumped around the ground loop in the garden for reheating.

The basic operation of an air source heat pump is as follows:
An air source heat pump technology is simple at its heart. During the day the sun’s rays heat up the air. Heat pump technology simply extracts this free energy. Even at ambient temperatures as low as -20°C there is enough heat in the atmosphere for an air to water heat pump to heat your home. The only additional energy the system requires is the power to drive the heat pump compressor. In fact, if the heat pump is connected to a clean energy source, such as solar power (ask for further details), running costs and CO2 emissions can be reduced even further.
Outside air comes into contact with the liquid refrigerant in the evaporator. The refrigerant absorbs the ambient heat from the air and evaporates. The resulting gas passes through to a compressor, which increases the pressure, and therefore the temperature, of the gas. The hot compressed gas now passes to the condenser where it is passed over a cold surface. This surface absorbs the heat from the gas and uses it to heat your water. As the gas cools it returns to its liquid state. The liquid travels to the expansion valve where it resumes normal pressure and then returns to the evaporator to be recycled around the system. The hot water is stored in the tank and then pumped around the house or to your tap to provide central heating and hot water as required.

The basic operation of a water source heat pump is as follows:
A water source or lake heat pump effectively works in the same way as a ground source heat pump. By using heat stored in the lake water and lake bed. The collector circuit is laid on the bottom of the waterway and carries heat to a waterside home. Using heat from a lake reduces energy consumption in a very efficient way.
