Why have a Heat Pump?

Heat pumps generate heat from the energy found in the natural environment, which makes heating your home an energy efficient process. A Heat Pump system distributes heat via your wet central heating system. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time and larger surface areas.

How does a Heat Pump work?

A heat pump generates heat by transferring energy, like a refrigerator in reverse cycle.

The evaporator extracts energy from the renewable source (air, water, geothermal) by forcing the liquid to transform into a gas.
The compressor compresses the gas, which raises its temperature.
The condenser exchanges the heat from the gas to the heating system, and the gas returns to a liquid state.
The expansion valve lowers the pressure of the refrigerant, which triggers evaporation and the cycle begins all over again.

How do you install a Ground Source Heat Pump?

Ground source heating is pure solar energy that's stored in the ground. As the sun begins to shine more strongly in the spring, energy is stored, beneath the surface of the ground. By the time autumn comes, enough energy from the sun, will have been stored to heat your home over a freezing cold winter.

Using a liquid-filled loop, also known as a collector, you can collect the solar heat that's stored deep down in the earth, at the bottom of the lake or a few metres under your lawn. The type of heat source that is suitable for your needs will depend on your home's energy requirements, your heating system and the nature of your property.
