BIGGER DOES NOT EQUAL BETTER A common misconception is that a
Air Source Heat Pumps (ASHPs) can be an excellent way for homeowners to lower their carbon footprint while efficiently keeping their homes warm. CALCULATIONS ARE CRUCIAL One vital skill for effective installations is the ability to carry out comprehensive heat loss calculations. Heat loss calculations are essential for creating the right balance between the energy requirements of a home and the naturally occurring heat loss through the
bigger system will inevitably be better. The thinking is that, if an ASHP is able to provide heat to a large house with 10 bedrooms, it should easily handle a smaller home with fewer rooms. However, the reality is that an ASHP sized to heat a larger home will not be as efficient in a smaller one. All oversized heating appliances, including ASHPs, consume more energy than those that are correctly sized to the property. Heating installers have the opportunity to discuss this topic with their customers and help them understand that an ASHP that is properly sized using heat loss calculations will lower their energy bills along with their carbon emissions. All heating engineers should be aware of this and be ready to have these conversations with their customers to ensure they understand their new systems. Installers can find more information below:
