Baseboard heaters are 100% efficient, converting 100% of the energy used to heat. Heat pumps can be as much as 200% to 300% efficient, supplying the same amount of heat for much less energy.
The efficiency will vary depending on a number of factors including the type of heat pump, the specifications of the individual unit, and the outside temperature. Correct sizing and installation of the heat pump is essential to achieving maximum potential energy savings, so be sure to hire a professional installer.
In Newfoundland and Labrador, because of our heating dominated climate, one of the most important things to look for in a heat pump is a high Heating Seasonal Performance Factor (HSPF). We recommend a HSPF of 10 or higher for mini-split heat pumps and 9 or higher for multi-split heat pumps.
