How does a heat pump compare to traditional boilers in terms of efficiency?

Heat pumps typically have higher efficiency ratings compared to traditional boilers because of their method of operation. They transfer heat from the outside air (even in cold temperatures) into the indoor space, utilizing electricity to move heat rather than generate it directly. This process often results in a higher coefficient of performance (COP), which measures the ratio of useful heating or cooling provided to the energy consumed.

While traditional boilers convert fuel into heat, heat pumps can produce several units of heat for every unit of electricity they consume, leading to better energy efficiency. This makes heat pumps a more sustainable option, as they can provide the same level of comfort while consuming less energy and producing lower greenhouse gas emissions over their operational lifespan.

The other options provide insight into aspects that are not entirely correct when comparing heat pumps to conventional boilers, as they may overlook the broader efficiency benefits and environmental advantages presented by heat pumps in diverse climates.
