We recently had our friends from Efficiency Maine in to talk to us about the energy efficient product that more Mainers are using in their homes, heat pumps. It turns out that many might not be getting the most out of them. Here's why:

The thermostat for the heat pump is right on the unit, which is usually placed high on the wall near the ceiling where the air is warmer. If you set the thermostat to 65, that temperature will be achieved at the heat pump level. The pump will turn off, but the thermostat for your main furnace will read a colder temperature and kick in.

The key is to set the heat pump temperature a few degrees higher and your furnace temp to a few degrees cooler. The heat pump will warm things up much more efficiently and cost effectively if you let it do it's work.

Here is a video from Efficiency Maine about heat pumps.
