The idea of running both a furnace and heat pump can feel a little strange at first. After all, why should you need two sources of heat? While furnaces and heat pumps both produce energy-efficient heat, the differences in their design actually make employing both of them a potential option. It’s not for everybody, but with the right conditions you could truly benefit from having a furnace and a heat pump.
You should consider several factors in order to determine if this type of setup works for you. Your local climate and the size of your home are both especially important, particularly for the heat pump. This is because numerous models of heat pumps begin to work less effectively in cooler weather and larger homes. At the same time, you can still take advantage of heat pump installation in Covington.
Heat Pumps Can Be Less Reliable in Winter Weather
Heat pumps are typically less efficient in cooler weather as a result of how they create climate control to start with. Compared to furnaces, which combust fuel to create heat, a heat pump reverses its stream of refrigerant to draw heat from outdoor air. This heat is then drawn inside and distributed all through your home. Provided there is still a little heat energy in the air, a heat pump should function. But the colder the temperature, the less effective this process is.
The less heat energy is accessible outside, the more time is needed for a heat pump to pull heat indoors to reach your desired temperature. It can depend on the exact make and model, but heat pumps may start to drop in efficiency at temperatures of 40 degrees and under. They can still be an energy-efficient option until 20-25 degrees, after which a gas furnace should be more effective.
What Temperatures Do Heat Pumps Run Best In?
Heat pumps manage best in temperate climates 40 degrees and up. Having said that, you don’t have to miss out on the benefits of a heat pump just because your local climate is cold. In fact, that’s why using both a furnace and heat pump may be worth the expense. You can favor the heat pump for energy-efficient heat until the weather is chilly enough to justify switching to something like a gas furnace.
Certain makes and models claim greater performance in winter weather. For example, the Lennox MLA heat pump is capable of running at 100% capacity at 0°F. It can even continue running in temperatures as low as -22°F. For maximum energy efficiency, you’ll likely still want to switch to the furnace in particularly cold weather.
So Should I Get a Heat Pump if I Have a Gas Furnace?
If you’re thinking about maintaining the most energy-efficient HVAC system achievable, having a heat pump and gas furnace at the same time is worth the investment. Not only is a dual-heating system versatile, but it offers other perks including:
- Dependable backup heating – A redundant heating system means even if one fails, you still have the ability to heat your home. It won’t always be the most energy efficient, but it’s better than living in an unheated home while you wait for repairs.
- Reduced energy costs – The ability to decide which heating system you use based on the highest energy efficiency reduces your total costs. Smaller heating bills over the life of these heating systems can really add up to plenty of savings.
- Less strain on both systems – Instead of running one system all winter long, heating resources are divided between the furnace and heat pump. Crucial components could live longer given that they’re not under nonstop use.
If you’re still uncertain about heat pump installation in Covington, don’t hesitate to contact your local professional technicians. They can review your home’s comfort needs and help you figure out if a dual-heating HVAC system is the better option.
