Heat pumps offer an energy-efficient alternative to boilers, furnaces and air conditioners. Some models provide cooling and others can both heat and cool. Like a refrigerator, heat pumps use electricity to move heat from a cool space into a warm one, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into the building; during the cooling season, heat pumps move heat from the building to the outside. Because they move heat rather than generate heat, heat pumps can provide much more energy than they consume.
Air-source heat pumps are the most popular because of their lower cost. They transfer heat between the building and the outside air. With SEER ratings as high as 26 heat pumps do an excellent job at heating, cooling and summer dehumidification. The efficiency of most air-source heat pumps drops at low temperatures. We recommend that when we are going to have extended periods of temperatures’ below 5 degrees you consider a secondary heat source such as your existing system or a wood stove. For homes without ducts, air-source heat pumps are also available in a ductless version called a ductless mini-split heat pump.
The majority of heat pumps we sell are Mitsubishi ductless mini splits. These units are super efficient, energy star rated, and reliable. One of the biggest selling points is that both the indoor and outdoor units are basically silent. When combined with a solar electric system using a heat pump is the ultimate way to provide free space heating and cooling with zero pollution. If you are building a new high efficiency home a split zone heat pump may be the perfect, affordable, environmentally friendly, heating and cooling system.
Mitsubishi split zone systems allow you to purchase one outdoor unit and multiple indoor wall mounted, remote controlled, air handlers. The outdoor unit can be located anywhere. Only a small refrigerant & drainage line is run and comes through the wall to the indoor unit.
