Heat Pumps

Ground Source Heat Pump

A ground source heat pump is an electrically powered system that uses the natural energy stored in the earth to heat your home. The principle is simple, and the result is low-cost comfortable heating that uses sustainable energy and causes no direct emissions or other damage to the environment. Ground source heat pumps are suitable for a variety of different properties and are designed to be the sole source of heating and hot water in the home. If however the demand on the hot water is high on the odd occasion a electrical immersion element cuts in automatically for a fast heat up.

For every single kilowatt of electricity used to power the ground source heat pumps, this system could generate four kilowatts or more in energy for your home.

Three types of collector are used:

  1. Ground Loop a coil run throughout your garden typically 1 meter down with 1 metre gaps. A large piece of land is required.
  2. Compact collectors (grid of tubes) linked together and laid in a trench at an angle of approximately 30 degrees.
  3. Bore hole. A hole bored into the ground a little over 100m which a series of pipes is then installed into this.

Air to Water Source Heat Pump

Air source heat pumps are intended to be the sole source of heating and hot water production for the home, giving homeowners the option of removing the existing heat source from the property. If however the demand on the hot water is high on the odd occasion a electrical immersion element cuts in automatically for a fast heat up.

The air to water heat pumps use the constant energy available in the air with a refrigerant circuit to allow the temperature to be boosted to a useful level for the provision of heating or hot water for the home.

The technology works on a similar principle to the way a domestic fridge works. A external fan unit draws in the outside air and converts the latent heat it contains on even the coldest of days working to minus 20;C into hot water. This is then circulated to an internal heat store which then circulates it to the central heating system or the internal hot water cylinder.

When properly installed and designed an air source heat pump can produce up to 4 times more energy to the home than the electrical energy it uses to operate.
Joining it all together

Aquaheat can install a system can perfectly combine the benefits of a heat pump with solar thermal. During summer, the solar energy system supplies almost all of the heat required for the hot water. When the heating is on, the heat pumps either ground or air generate energy from the environment. The heat pump is therefore only in operation during the colder months. This markedly lengthens the service life and increases the efficiency of the overall system.

The operating costs for a heat pump with solar installation are lower far than for all other systems without solar thermal.
