                Energy Efficiency 2024 Does a heat pump work in a house with poor insulation?Does a heat pump work in a house with poor insulation?

                Even with poor insulation, heat pumps still save energy As well as reducing CO2 emissions, a heat pump can use three to five times less energy than an efficient gas boiler. However, an often-heard argument when considering replacing a gas boiler is that the house needs to be well-insulated for the heat pump to work. Heat pumps do work best in a well-insulated house because their heat output is at a lower temperature than a traditional boiler, and they perform best when providing a consistent heat output with minimal heat losses. If a house loses a lot…
