Heat pump water heater Intro

Heat pump water heater, its working principle is similar to air conditioners. It uses a small amount of electric energy to drive the compressor to run . Absorbs a large amount of heat energy from the air,the gaseous is compressed by the compressor into a high-temperature, high-pressure liquid state, and then enters the condenser to release heat and heat the water... Such continuous circulation heating can heat the water to 50° C~65°C.

Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy-efficient than conventional electric resistance water heaters. They achieve this by utilizing a technology used often in refrigerators, which allows them to transfer heat from one area to another. Heat pump water heaters are sometimes called “hybrid” water heaters because, during periods of high hot water use, they can switch to standard electric resistance heat automatically.

A hybrid water heater, also known as a heat pump water heater, is a heater that combines a traditional water heater and a tankless heater. Modern households can enjoy hot water without spending too much. Known as heat pump water heaters (HPWHs), a hybrid electric water heater marries a tankless water heater’s energy efficiency and a storage tank system’s high hot water capacity for large households.

the difference between hot water system and heat pump
A heat-pump hot water system uses much less electricity than an electric storage hot water system. This is because it only uses electricity to drive the compressor and the fan, instead of using electricity to heat the water directly with an electric element.

Advantages and Disadvantages of a heat pump water heater
Disadvantages: Heat pump water heaters can take a long time to produce larger volumes of hot water. This may not be a big deal during the summer when the unit can easily draw from warm air, but it can be a problem during the cold winter months.

Advantages: Heat and Cool Your Home, A Longer Useful Life, Heat Pumps Waste Less Energy, Reduce Your Carbon Footprint.


The average heat pump water heater, on the other hand, costs around $1,400 (though you can find them cheaper, especially with rebates) which is about $800 more than a typical electric water heater. Unit cost — Heat pump (hybrid) hot water heaters cost between $1,200 for 50 gallon tanks to $2,500 for 80 gallon tanks made by the highest end manufacturers. The tank size and product quality influence the unit cost most.

Cost to run an electric water heater?
Simply, For electric water heaters, including heat pump units. You need to know or convert the unit cost of electricity by kilowatt-hour (kWh). 365 days/year x 12.03 kWh/day ÷ EF x Fuel Cost ($/kWh) = annual cost of operation. Example: A heat pump water heater with an EF of 2.0 and an electricity cost of $0.0842/kWh.


Simply, Shut the power off to the electric water heater and shut off the main water supply to the house. 2. Connect a hose to the bottom of the tank and run the hose to the outside. Drain the old water heater. 3. Use the pipe cutters to cut the pipes to the water heater and remove it. 4. Put the new heat pump water heater into place.


Where should I install my heat pump water heater?
You should try to have your heat pump water heater installed as close as possible to your main areas of hot water use (i.e. bathrooms, laundry, kitchen etc.) so that the pipes are shorter. This helps to minimise heat loss and decrease the time it takes for hot water to reach the taps. These units are also not recommended in unheated spaces, such as garages, because they would rely more on the electric mode due to the wide variances in temperature of the air surrounding the water heater.
Space for a heat pump water heater
A heat pump water heater needs to be placed in an unoccupied space with sufficient room (around a thousand cubic feet of air, or a 12′ by 12′ space) for it to access the heat it needs. It cannot be placed in an area that grows extremely cold in winter such as an unheated garage.
Do heat pump water heaters need to be vented?
Install residential size heat pump water heaters in an area no smaller than 1,000 cubic feet. If installed in smaller areas, extra ventilation must be provided; commercial units require even larger spaces.

Worth it?

Heat pump water heaters use over 60 per cent less electricity than a traditional electric water heater, reducing your household electricity bill and greenhouse gas emissions. They can be easily installed to replace most traditional electric water heaters, without the need for a gas connection or solar panels on your roof.

Relate Question

Do heat pump water heaters use a lot of energy?
An ENERGY STAR certified heat pump water heater uses up to 50% less energy, on average, than a standard electrical water heater. Saving energy saves money and reduces your carbon footprint. Heat pump water heater (HPWH) technology does not generate heat directly. It moves heat from one place to another.

How loud is a heat pump water heater?
Be aware that these mechanical components produce noise—often significantly louder than a refrigerator. Heat-pump water heaters I’ve examined have noise ratings from 55 to 65 decibels (dB), which is a large range of variability (65 dB is ten times as loud as 55 dB).

Does a heat pump water heater dehumidify?
Heat pump water heaters dehumidify the space they’re installed in, significantly reducing the need to run your dehumidifier.
