Explaining Heat Pump Training

Stroma Certification is pleased to work in partnership with Optimum Energy, who manage course bookings and run this Heat Pump course. This course is suitable for DEAs because it allows a Stroma member to add an extra required service when attending site, which will save on time and cost in the process.

Over the course of the next few years heat pumps will become more energy cost competitive, with promised heavy government taxation on heat sources that burn fossil fuels. Therefore, it is essential that there are enough competent systems surveyors and installers to enable the efficient design and installation of Ground Source Heat Pumps (GSHP) and Air Source Heat Pumps (ASHP).

Heat Loss Calculations
Prior to installing a heat pump, an up to date EPC must be completed as well as a heat loss calculation. It is important to ensure the correct size of system is installed, so a full room-by-room heat loss calculations are necessary. This calculation will account for the size of the rooms, the insulation levels of both the walls and windows, as well as the height of the rooms.

The calculation brings together the amount of space that needs heating, along with the building’s materials and their capability to reduce heat loss from the property (u-values). In addition, other variables, such as air change rates, orientation, glazed areas and solar gain, expected comfort temperatures, and the lowest temperature expected in winter for that area are considered.

Heat Pumps

“The government has set targets for the removal of fossil fuel-based heating systems by 2050, and for the UK to work towards becoming a carbon neutral country. As part of this strategy heat pumps have become the heating source of choice, as heat pumps do not produce carbon at source.”
