Are heat pumps the best replacement option for gas boilers? There is a debate whether this technology would not work well in some type of climate, such as in cold Scottish winters. In fact, heat pumps are an energy-efficient heating solution, but their effectiveness in cold weather varies. While they generate more heat energy than they consume, they can ice up in freezing temperatures, though most have defrost cycles.
Ground- and water-source heat pumps maintain stability year-round. However, improper sizing and installation can lead to inefficient performance. Moreover, heat pumps provide lower-temperature water than gas boilers, which may require radiator and pipework upgrades. To maximise heat pump effectiveness, homes should also focus on improving insulation and energy efficiency. While heat pumps alone will not solve all heating challenges, they play a vital role in the broader campaign to make buildings more energy-efficient, contributing to reduced emissions.
