A dual fuel heat pump is a type of air source heat pump that can work in combination with a forced air furnace system. One of the advantages of this system is that the forced air furnace may be an existing system or a new system. In addition it can be fueled with propane or natural gas. Due to the fact that two sources of fuel are able to be used for heating, this type of heat pump is not only efficient but also cost effective. When considering a dual fuel heat pump guide, you will need to consider the best option to use with your current heating system. Based on your current system, there are three options. They are forced-air with ductwork combined with a plenum heater, a fossil fuel boiler combined with an electric boiler and supplemental electric heat combined with ceiling panels, cove heat or an electric baseboard.

Forced Air with Ductwork with a Plenum Heater

This type of combination system is typically installed where the existing ductwork and furnace converge. The air becomes warm as it moves over the heating elements that are located inside the plenum heater. The primary advantage to this type of system is that it is a low cost option that can heat the entire house.

Fossil Fuel Boiler with an Electric Boiler

This is an extremely compact system that heats water that is distributed to hydronic baseboards, radiators or underfloor hydronic heating system. This option is a good choice because it can be easily connected to existing piping.

Supplemental Electric heat with other Options

When there are areas in the home that are not heated well with existing heating then it may be a good idea to add supplemental electric heat. This can be done through a combination with cove heat, electric baseboards or ceiling panels. Electric baseboards feature units that are installed close to the floor. This type of system has a low up-front cost and provides heating that is zoned. With a cove heat combination, radiant heaters will be installed close to the ceiling. This type of system also provides heating that is zoned; however, the units will be safely removed from possible hazards such as furniture and drapes as well as children. Ceiling panels feature radiant panels that are imbedded along with heating cables in the ceiling. This type of option offers instant comfort.
