Cambride scientists recommend careful cost assessment before switching to heat pumps

The researchers said that an increment in heating demand due to the use of heat pumps can be accurately predicted based on heating hours, local climate, heat loss and thermal mass. They also recommended including heat loss and thermal mass parameters in buildings' energy performance certificates, so households can make more informed decisions before changing their system.Heating demand might increase by more than 20% after a UK household switches from gas boilers to heat pump, new research from Cambridge University have shown. In the study "How do heat demand and energy consumption change when ...
