The idea of using both a furnace and heat pump might feel a bit odd at first. After all, why would you need two heating systems? Although furnaces and heat pumps both deliver energy-efficient heat, the changes in their design really make employing both of them a potential option. It’s not for all of us, but in the right conditions you will absolutely benefit from having a furnace and a heat pump.
You’ll need to think about several factors in order to decide if this sort of setup suits you. Your local climate and the dimensions of your home are both especially important, particularly for the heat pump. This is because numerous models of heat pumps start to function less efficiently in winter weather and large homes. Even so, you can still reap the benefits of heat pump installation in Holdrege.
Heat Pumps May Be Less Reliable in Winter Weather
Heat pumps are commonly less effective in colder weather as a result of how they provide climate control to start with. As opposed to furnaces, which burn fuel to create heat, a heat pump reverses its supply of refrigerant to extract heat from outdoor air. This heat is then brought inside and distributed around your home. Provided there is still a little heat energy in the air, a heat pump will function. But the cooler the temperature, the less effective this process is.
The less heat energy is available outside, the more time is needed for a heat pump to draw heat indoors to maintain your desired temperature. It might depend on the type of make and model, but heat pumps may start to lose out on efficiency at temperatures of 40 degrees and colder. They can still be an energy-efficient option until 20-25 degrees, at which point a gas furnace is more effective.
What Temperatures Do Heat Pumps Work Best In?
Heat pumps manage best in moderate climates 40 degrees and up. That said, you don’t have to lose out on the benefits of a heat pump just because the local climate is cooler. After all, that’s why having both a furnace and heat pump can be worth the costs. You can use the heat pump for energy-efficient heat until the weather is cool enough to call for shifting to something like a gas furnace.
A few makes and models tout greater performance in cold weather. For example, the Lennox MLA heat pump is capable of operating at 100% capacity at 0°F. It can even continue running in temperatures as cold as -22°F. For optimum energy efficiency, you’ll likely still want to swap to the furnace in especially cold weather.
So Should I Put in a Heat Pump if I Have a Gas Furnace?
If you’re thinking about maintaining the most energy-efficient HVAC system achievable, owning a heat pump and gas furnace at the same time deserves the investment. Not only is a dual-heating system versatile, but it features other benefits including:
- Reliable backup heating – A redundant heating system means even if one stops working, you still have the ability to heat your home. It may not be the most energy efficient, but it’s better than shivering in an unheated home while you hold out for repairs.
- Reduced energy costs – The ability to choose which heating system you use depending on the highest energy efficiency lowers your total costs. Smaller heating bills over the life of these systems can really add up to plenty of savings.
- Less strain on both systems – Compared to running one system all winter long, heating duties are divided between the furnace and heat pump. Crucial components could survive longer given that they’re not under continuous use.
If you’re still unsure about heat pump installation in Holdrege, don’t hesitate to reach out to your local certified technicians. They can evaluate your home’s comfort needs and help you determine if a dual-heating HVAC system is the best option.
