Heat Loss Calculations (Heat Pump Sizing)

Heat loss calculations can be carried out to establish the size and specification of both Air Source Heat Pumps and Ground Source Heat Pumps.

Please watch our services video

Please click our maps for SAP Calculations/SAP Ratings in your area.

Heat loss calculations for  both Air Source Heat Pumps and Ground Source Heat Pumps are applicable to new dwellings, conversion schemes and existing properties.

There are many factors relating to calculating the size of Air Source Heat Pumps or Ground Source Heat Pumps, such as location, area and volume of property, heat loss,  insulation levels etc.

The need for renewable energy, such as air source heat pumps or ground source heat pumps, is increasing due to changes in Building Regulations, and more significantly, the Code for Sustainable Homes.

Using renewable technology for new dwellings will ensure guidance in Approved Document L1A is met. This will also be beneficial for satisfying guidance in Approved Document L1B when undertaking conversion schemes or excess glazing calculations.

Having heat loss calculations carried out by Richmond Thermal Solutions at the design stage of any scheme can help with the sizing of heat pumps, as we will also assist with the thermal specification of the project. Once RTS has undertaken heat loss calculations, we then pass these figures on to the installer who can then size up the heat pump.

Running Costs of Heat Pumps versus Carbon Footprint.

There is often confusion between ‘running costs’ and ‘carbon footprint’ when considering heat pumps. Approximate running costs are calculated (using SAP 2009 Methodology)  when SAP calculations are carried out for new dwellings or conversion schemes.

While the carbon footprint (Carbon Emissions Rate) will be extremely good, the running costs may not be accurate. It is always advisable to speak to the installer for an accurate breakdown of running costs after the heat loss calculations [no caps, currently just one cap on ‘Heat’] have been carried out.

Please contact us if you have any questions regarding heat loss calculations.
