Your Current Radiators: The Common Scenario
For many homes, especially properties like the 1930s bay-fronted semis common around Rectory Lane in Standish, existing radiators might be undersized for heat pump flow temperatures. Heat pumps typically operate at lower flow temperatures (often 40-50°C) compared to traditional gas boilers (which can run at 70°C+). This means a radiator that kept a room perfectly warm with a boiler might struggle with a heat pump. Our survey calculates the heat loss for each room and then assesses the output of your current radiators at these lower flow temperatures. We'll tell you exactly which radiators, if any, will need upsizing to meet the room's calculated heat demand.
