Dual Fuel Systems in Ashburn, VA

You may or may not know about heat pumps, the climate control systems that evaporate and condense refrigerant to move heat from one place to another. Heat pumps don’t burn fuel to generate heat, instead relying on the thermal energy in the air outside. These systems are incredibly energy efficient, but they do have their faults. If you want to get all the benefits of using a heat pump system, but don’t want to have to deal with the cons of using one, you should consider getting a dual fuel system. AllTech Services, Inc. offers a full range of dual fuel heating system services, from installation to repair and maintenance. Call today to schedule an appointment with one of our heating experts.

How Dual Fuel Systems Work

Also called hybrid heating systems, dual fuel systems comprise two separate parts. The first part is the heat pump, which is installed outside the home. The second part is the furnace, which is installed inside the home. The furnace is like any other gas, oil, or electric furnace, with the exception of a heat pump coil installed above it. The furnace and the heat pump are connected by power and refrigerant lines.

When in heating mode, the heat pump unit outside evaporates refrigerant to absorb heat from the surrounding air. It then sends the refrigerant gas inside to the coil above the furnace, where it is condensed back into liquid to release heat into the air being circulated through the ducts.

When the temperature drops low enough that the heat pump becomes an inefficient use of energy, it is said to have reached the balance point. When that happens, the heat pump turns off and the furnace turns on to continue heating the home.

The Benefits of Dual Fuel Systems

Heat pumps are very energy efficient, most of the time. However, they still rely on thermal energy in the outside air in order to keep the home heated. As the temperature of the air outside drops, the amount of available thermal energy will drop as well. Eventually, there will be so little thermal energy available that the heat pump will not be able to efficiently heat the home.

Furnaces, on the other hand, are quite good at keeping a home heated no matter how cold it gets outside. Of course, since they have to burn fuel to generate heat they’re not nearly as energy efficient as heat pump systems. This is the beauty of the dual fuel heating system: the heat pump can efficiently heat the home and save money as long as it can. On extremely cold days, the heat pump can turn off and the furnace will be used in short bursts to keep the home warm until the temperature rises outside. You get the best of both worlds with a dual fuel heating system.
