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. Of course, the colder the weather, the harder the heat pump needs to work to provide heat. Below a certain temperature threshold, the system becomes less efficient.
How cold is too cold for a heat pump to work?
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 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.
Will a heat pump work in cold weather?
Yes, heat pumps work in extremely cold temperatures. In the past, some heat pumps worked better in frigid climates than others. However, thanks to technological advancements, most heat pumps on the market today can keep you and your family warm on even the coldest of winter days in Boston.

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.
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.
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!
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.
How warm can a heat pump get your house?
The average heat output can be 85-92°F; however, how warm the output from your heat pump will be is determined by several factors, including age and condition of the heat pump.
At what temperature does a heat pump switch to emergency heat?
Many people think that Heat Pumps don't work in cold weather and they are supposed to use the Emergency Heat whenever it gets really cold... Wrong! What is Emergency Heat? Simply put, all Heat Pumps in northern climates (below 35 degrees) need a supplemental heating source.
At what temperature should you turn off your heat pump?
Which heat pump is best for cold climates?
Based on our research, the best cold climate heat pump is Mitsubishi's Hyper-Heating, or H2i. Listed as Mitsubishi's M-Series or P-Series for home installation, these heat pumps maintain their full heating capacity down to 5F, and can produce useful heat down to -13F.
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.
How long do heat pumps last?
The life expectancy of a heat pump depends on several factors, such as the type of heat pump, your location, and how well the heat pump is maintained. Heat pumps normally last an average of 15 years, though some can wear out after a decade. Some of the newer units being manufactured today can last a bit longer.
At what temperature does a heat pump switch to emergency heat?
Many people think that Heat Pumps don't work in cold weather and they are supposed to use the Emergency Heat whenever it gets really cold... Wrong! What is Emergency Heat? Simply put, all Heat Pumps in northern climates (below 35 degrees) need a supplemental heating source.
At what temperature should you turn off your heat pump?
When should you use emergency heat on a heat pump?
Emergency heat is ideal for when the outside temperature is too cold for your heat pump to keep your home warm. If the heat pump freezes over or becomes damaged, then you should switch to emergency heat and call an HVAC service provider.
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.

How warm can heat pump work in winter?
How do I keep my heat pump from freezing?
Heat pumps are designed to pull cold air from a home and not freeze up. To prevent this from happening, the heat pump must go into defrost mode when it becomes too cold. Defrost mode tends to switch the heat pump into air conditioning mode for a while till it unfreezes. After which, you can go back to heat mode.
Do all heat pumps have emergency heat?
All heat pumps have a backup heat source known as emergency heat or ancillary heat. When the outside temperature is below 30 degrees, heat pumps auto-engage emergency heat to keep up with demand from the interior thermostat.
How do heat pumps work in cold climates?
The refrigerant can absorb heat even in extremely low temperatures of -20 °C, which is why heat pumps are able to work in cold climates. This evaporated refrigerant is then compressed, which increases the temperature further.
Which types of heat pumps are best for cold climates?
Which Types of Heat Pumps Are Best for Cold Climates? Just a few feet below the ground, the temperature ranges from 45° F to 75° F. Geothermal heat pumps take heat from the ground and use it to heat the home or office building. Because the temperature doesn’t fluctuate much, the ground can be a reliable source from which to pull heat. 3
What temperature is too cold for a heat pump to work?
However, if the temperature drops to around -8.3 °C, your heat pump’s efficiency could drop to around 2.3 CoP. If the outdoor temperature drops too low for your heat pump to produce any heat, a backup may be required.
Do air source heat pumps work best in hot weather?
Air source heat pumps work best when the weather is hot, as that means there’s an abundance of heat in the air that can be absorbed and used to heat your home. In hotter locations, you’d generally rather have an air source model than a ground source heat pump, as you’ll be able to take full advantage of temperatures above 20°C.
