When looking for a brand new or alternative heating system, you’ll more than likely come throughout the time period “dual fuel heat pump” or “hybrid heat pumps”. A salesman may even inform you they’re a greater choice to your house. But what are they, and how do they work?
Dual Fuel Systems
A twin gas system is solely a regular electrical warmth pump that has a fuel furnace as a backup. The fuel furnace normally runs on propane. The electrical warmth pump makes use of electrical energy to energy the motors and the compressor within the pump.
The pump has a refrigerant that circulates in a coil positioned outdoors. When it’s chilly, the refrigerant attracts latent warmth from the surface air and this warmth is concentrated when the refrigerant strikes via the compressor.
The refrigerant then goes via a coil put in inside the home. It decompresses because it passes via this second coil, and in doing so, releases the warmth vitality collected from the surface. That warmth is then despatched via the entire home by a blower.
The one caveat about this electrical heating system is that it doesn’t work beneath a sure temperature.
The Balance Point and the Gas Furnace
There is normally sufficient warmth even in chilly air to heat a home, however the means of an electrical pump to gather this warmth and use it on this approach is proscribed by the temperature outdoors. The stability level is the temperature the place a warmth pump can now not extract warmth from the air outdoors.
When a twin gas heating system is being put in, the contractor additionally provides a thermostat that checks whether or not the surface temperature is above the stability level. If it is, an automated system shuts down the warmth pump and prompts the furnace. When the surface temperature rises above the stability level, the alternative occurs; the fuel unit shuts down mechanically and the warmth pump is activated.
Because pure fuel is comparatively low-cost, the entire system is cheap to run in comparison with different heating programs.
