Air-source Heat Pumps
An air-source heat pump can cut your heating costs and increase efficiency during the spring and fall heating seasons. Approximately 75% of heating hours in our area are 10 degrees or above; the air-source heat pump is approximately 200% efficient at 10 degrees.
Incorporating an air-source heat pump with a storage furnace increases efficiency because the furnace is electronically programmed to assist the heat pump.
Incorporating an air-source heat pump with a gas or oil furnace increases efficiency because the furnace is designed to be most efficient in colder temperatures. The 200% efficient heat pump carries the heating load in warmer temperatures when your furnace is least efficient.
Using a 14-SEER (Seasonal Energy Efficiency Ratio) or greater air-source heat pump (or central air conditioner) is highly recommended.
Heat pumps and air conditioners can be controlled and metered for our controlled load rates.
Ground-source Heat Pumps
A ground-source heat pump does not burn any fuel to create heat. It simply transfers the earth’s energy to your home. At the earth’s constant temperature of 40 to 50 degrees, a loop through the earth, coupled with an indoor heat pump (about the size of a conventional furnace), provides 300% efficient heat. The heat pump can be connected to ductwork or hydronic tubing.
In the summer, you flip the switch to reverse a ducted system for air conditioning.
