The Common Case: Insulation and Radiator Requirements
Often, the primary reason a heat pump isn't immediately recommended is inadequate insulation or undersized radiators. Heat pumps operate most efficiently at lower flow temperatures than gas boilers. Our survey meticulously calculates the heat loss for each room, factoring in fabric, glazing, orientation, and ventilation. We then assess your existing radiators' output at these lower flow temperatures. If the heat loss is too high, or the radiators are significantly undersized, the system will struggle to heat your home effectively, leading to dissatisfaction. We provide a realistic list of necessary upgrades.
- Room-by-room heat loss calculated accurately
- Existing radiator output assessed at heat pump temperatures
- Clear guidance on radiator upsizing, if required
