Most dual fuel systems are designed to use heat pump heating on days where the temperature is above 35°-40°F. Once temperatures drop below 35°F, the system automatically switches to gas furnace heating.Because furnaces and heat pumps can use the same kind of air ducts to move air through your home, it’s a relatively straightforward process to replace your furnace with a heat pump. Heat pumps are a reliable method of home heating, and some models can work when it is still as cold as -27° C outside.
What temperature should a furnace be switched to a heat pump?
Most dual fuel systems are designed to use heat pump heating on days where the temperature is above 35°-40°F. Once temperatures drop below 35°F, the system automatically switches to gas furnace heating.
When should I use heat pump vs furnace?
To generate heat, furnaces burn oil or gas, while heat pumps run on electricity, drawing heat from outside air—even cold air—and transferring it indoors. Because of how they work, heat pumps produce less heat than furnaces and work best in warmer climates (zones 1-3 on the U.S. Department of Energy climate zone map).
At what temperature is a heat pump useless?
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Do you need a heat pump If you have a furnace?
The biggest difference between a heat pump and a furnace is that a heat pump can cool and warm your home. If you'll need to replace both your furnace and air conditioner soon, instead of buying both, you can simply buy one heat pump.

Is it cheaper to heat with gas or heat pump?
While exact operating costs depend on the climate where you live, the unit's efficiency, and local utility costs, for a single winter season, heating costs run an average of $1,550 for a propane furnace, $850 for a natural gas furnace, $900 for an electric furnace, and just $500 for a heat pump.
Is a heat pump cheaper to run than a furnace?
Energy efficiency Under ideal conditions, a heat pump can transfer 300 percent more energy than it consumes. In contrast, a high-efficiency gas furnace is about 95 percent efficient. Heat pumps are powered by electricity, so you can save substantially on fuel consumption.
Do heat pumps work below 30 degrees?
You can run a heat pump at all temperatures as it is designed to switch to emergency heat when it reaches below 25-30 degrees Fahrenheit. Therefore, there is no need to manually switch an air heat pump off, even in the coldest temperatures, because it was created with efficiency in mind.
Do heat pumps use a lot of electricity?
Heat pumps require some electricity to run, but it's a relatively small amount. Modern heat pump systems can transfer three or four times more thermal energy in the form of heat than they consume in electrical energy to do this work – and that the homeowner pays for.
How well does a heat pump work in cold weather?
ASHPs provide reliable heating when the refrigerant is significantly colder than outdoor temperatures. In moderate weather, cold climate heat pumps can operate at up to 400% efficiency — in other words, they produce four times as much energy as they consume.
Can I add a heat pump to my existing furnace?
You can add a heat pump to an existing furnace for those times of year when the climate is moderate and it might be more economical to run a heat pump rather than use gas, propane or oil.
Can I replace my furnace with a heat pump?
Because furnaces and heat pumps can use the same kind of air ducts to move air through your home, it's a relatively straightforward process to replace your furnace with a heat pump. Heat pumps are a reliable method of home heating, and some models can work when it is still as cold as -27° C outside.
Can you have a heat pump and a furnace?
You can have both a gas furnace and a heat pump in your home in what is known as a hybrid heating system. A hybrid heating system responds to changing temperatures and naturally acclimates to the most productive method of saving energy.
What is the most efficient setting for a heat pump?
Heat pumps operate most efficiently when holding a steady temperature. Turning a heat pump down when you're away or asleep may actually use more energy than leaving it on. The reason is that it has to work harder to come back to the desired temperature than it does to maintain it.
Should you leave your heat pump on all the time?
While heat pumps are the most cost effective way to use electricity to heat your home during the cooler months, leaving them running day and night is not economically efficient. According to Energywise, you should switch off your heat pump when you don't need it. This is to avoid excessive energy waste.
How does a heat pump and furnace work together?
A furnace creates heat that is distributed throughout a home, but a heat pump absorbs heat energy from the outside air (even in cold temperatures) and transfers it to the indoor air.
At what temperature is a heat pump useless?
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.

Should I turn my heat pump off in extreme cold?
Short answer: You should only set your heat pump's thermostat to “emergency heat” when your heat pump stops heating altogether.
Is a heat pump worth it?
In most cases, heat pumps are worth it. Heat pumps are usually more expensive to install, but you end up saving more money throughout the year with low maintenance costs, making heat pumps a great investment. Additionally, heat pumps are much safer with no risks for a gas leak, which can expose you to carbon monoxide.
What temperature should I set my heat pump in the winter?
Ideal Winter Heat Pump Temperature Settings According to the Department of Energy, 68°F is the sweet spot that balances comfort and energy efficiency during the fall and winter months. When your home is occupied and when family members are awake, a heat pump setting of 68°F keeps the living areas reasonably warm.
Are heat pumps a waste of money?
Myth #10: “Heat pumps are money wasters!” Are Heat Pumps a waste of money? Heat Pumps can provide up to 60% savings on your heating bill. Another important factor to consider when evaluating the cost of an ASHP installation is the amount you can save right now!
