Air Source Heat Pumps London & Nationwide

Recycling Heat from the outside air has never been more important

Ground Sun has been an air source heat pump company in London and nationwide for over a decade now and, in that time, we’ve fitted and installed domestic and commercial buildings with our quality Austrian and UK manufactured heat pumps.

We recognise that the Ochsner air source heat pumps are representative of an innovation step towards climate control that provides energy efficiency and sustainability; a balance that has eluded the market until recently. Suitable for use with radiator systems (thanks to the 68deg heat pump technology), underfloor heating and warm air convectors this technology can revolutionise buildings in which they are installed. Ground Sun is the premier installer of air source heat pumps in London and operates nationwide.

Air Source Heat Pumps (ASHP) and Table Source Heat pumps TSHP extract heat from the outside air and rain. This heat is absorbed at low temperature into a fluid, which passes through a compressor where its temperature is increased and this heat is transferred to heat emitters in the property.

Ochsner ASHPs can now offer efficiencies as good as Ground Source Heat Pumps and they are easier and quicker to install than ground source options. They are especially suitable where space is limited and horizontal ground loops or boreholes are not an option. The Ochsner GMLW 14 plus series offers excellent efficiencies with a COP (coefficient of performance) of 4.73 which is above 98% of ground source heat pumps on the market. ASHPs will provide you with an income through the Government’s RHI (Renewable Heat Incentive) Scheme, however, tariffs are lower than those for Ground Source Heat Pumps – see Grants and Incentives for more details.

EXTREMELY QUIET HEAT PUMPS

Air to water heat pumps from OCHSNER are the quietest on the market. In many parts of England, 35 dB, which corresponds approximately to whispering or rustling of leaves, must not be exceeded at the assessment point (i.e a bedroom window) .

The figure below shows the distance at which an OCHSNER outdoor unit may be positioned from the property boundary without exceeding 35 dB.

BECAUSE NATURE IS FULL OF COLOUR

Choose your preferred colour for the outdoor thermal table heat pump. In addition to the standard colours of anthracite grey, traffic white or white aluminium – OCHSNER also offers a multitude of other colours to allow the outdoor unit to blend perfectly into its surroundings. Choose your favourite colour from 1,625 RAL shades for your outdoor unit. Order based on sample cards “RAL Classic K7” and “RAL Design D2”.

How High Efficiency Air Source Heat Pumps Work

Air Source Heat Pumps operate through a very simple process where natural heat transitions from air, into a fluid. This process is achieved by lowering the temperature of the original heat source. The fluid that is produced through this process then travels through the pump’s compressor where it is heated up, going on to then heat the home’s circuit to serve as a warm water source.

The efficiency that such pumps offer is gained from the way in which the process uses free heat from the environment in which it is found (as opposed to generating the heat through typical fuel sources which include gas, oil and LPG).


Benefits of a High Efficency Air Source Heat Pump in the UK

In addition to providing energy efficiency, our air source heat pump installations in London present numerous other benefits, including:

  • Lower fuel bills (particularly if you are making the switch from electric heating),
  • A possible income if you join the Government’s Renewable Heat Incentive,
  • No need for inconvenient oil or gas deliveries,
  • Space and water heating,
  • Low maintenance requirements,
  • Can be far easier to install than ground source heat pumps.
