Instead of directly generating heat, heat pump water heater uses electricity to move heat from one place to another.Hence, they can be two to three times more energy efficient than conventional electric resistance water heaters. It should be installed in a space with excess heat, such as a furnace room.
The working principle of a heat pump is on the same principle as a refrigerator; however it does not pump out heat to keep it cool, rather they pump heat into the water. To pump a refrigerant through the system normally electricity is used. The heat absorbed through the air to the water in the tank is transferred through the refrigerant.
Most incentives are only supplied when the heat pump water heater is situated in a garage or other un-heated, un-conditioned space. HPWHs generally require installation in a room with 1,000 cubic feet of space so that enough ambient air is available for the water heater to run efficiently.
Down to a temperature around 25 to 30 degrees Fahrenheit, the heat pump is effective by itself. At that point, either a gas furnace or an air handler with supplemental electric heat will kick in and help heat your home.
How long does the heat pump last?
The life expectancy of a heat pump depends on several factors, like type of heat pump, location, and how well the heat pump is kept. Normally the life expectancy of a heat pump lasts an average of 15 years, though some might wear out after a decade too. However the latest units might last a bit longer.
In fact, many heat pumps may run continuously during bitterly cold weather. A properly sized and installed heat pump should run almost continuously when it is below 30 degrees or so. If you want the fan to run only when there is a need for A/C or heat, set your thermostat to “AUTO”.
How cold is too cold for a heat pump?
Well the thumb rule is below freezing (or approximately 32°F) defrost mode can be alarming. Hence, it’s crucial for heat pump operation in winter. On your outdoor components ice may begin to form when the temperature drops below freezing.
Can you replace a heat pump?
Replacing now will save you money in the long-term.
Your indoor unit is probably just as old as your outdoor unit since most systems are installed as pairs. Additionally, if your heat pump or air conditioner is 10 years old, it’s high time to replace it.
Is a two-stage heat pump cost worthy?
A two-stage heat pump will always cost you more to buy but will cost less to work. The two-stage blower and compressor combination will also supply more even heating and cooling. Some improved comfort can be experienced, but not a dramatic difference.
Most of the heat pumps are electrically powered, so they will cost you some money on the utility bill. However, heat pumps are much more efficient than gas fired furnaces and even most air conditioners.
