When installing a heat pump at home, it is important to upgrade your radiators for larger or more efficient ones. Heat pumps operate by heating water that runs through the radiators at a lower temperature compared to gas and oil boilers. This is known as the flow temperature. By using larger radiators that release more heat into the rooms over a longer period, you can achieve the same or even more heat output than before. It is highly recommended not to cut corners on radiators, and accredited installers must adhere to strict rules in calculating and fitting the right-sized radiators to maintain their accreditation status.
