It is important for you to understand the environmental impact and payback of your investment when choosing a heating system for your home.

Types of heating systems

Forced-air furnace

A forced-air system heats air in a furnace and uses a fan to force the warmed air through ductwork to the home's rooms.


A boiler system heats fluid (typically water, glycol or a mixture) and pumps the warmed fluid to a heat exchanger such as an in-floor system or baseboard radiator.

Heat pumps

Heat naturally flows from warm to cool zones. A heat pump is a machine that reverses this, taking heat from a cooler area and pumping it to warmer zone. Heat pumps require electricity to operate, and in Minnesota 60 percent of the electricity is produced by coal. Learn more about gas and electric system efficiency.

Ground source (geothermal) heat pump

A ground source heat pump can heat or cool a home by either collecting heat from the ground and pumping it inside to provide home heating, or cooling the home by collecting heat from the home and pumping it into the ground.

Air source heat pump (hybrid)

An air-source heat pump (hybrid) collects heat from the outside air during the fall and spring heating seasons and delivers it to the home exactly the same as a home's air conditioner would if operated in reverse.


Electric resistance heating

Electric resistance heating converts nearly 100 percent of the energy in the electricity to heat. However, electricity is produced from power generators that deliver only about 27 percent of the fuel's energy and have a very heavy impact on the environment. Electric resistance heating is significantly more expensive than heating your home with natural gas.
