Heat Pump Water Heater
There are several types of water heaters: the heat pump water heater, the electric water heater, the gas water heater and the solar water heater.
Operation of the heat pump water heater
The heat pump water heater provides hot water at lower costs. The water heater is associated with a quick heat pump for recovering the heat from the ambient air.
The principle is as follows:
- The heat recovered by the heat pump is transported to the thermodynamic water heater to heat the water contained inside.
- An electric resistance heater provides extra water heating when the heat pump is not enough. However, this occurs at low temperatures, typically below 7°C.
- The performance of thermodynamic water heater is higher than that of solar water heaters.
Installing the water heater
A heat pump water heater is usually installed in a utility room, laundry room or garage. The only requirement is to install it in a minimum area of 8m2.
If the room or area is less than 8m2, the suction and discharge of air must be made in another room or outside the dwelling.
Laundry rooms containing appliances are ideal for the installation of a heat pump water heater. Indeed, the heat generated by these devices will be recovered by the heat pump and used to heat water.
In addition, the heat pump water heater helps dry the atmosphere and can improve air quality.
Benefits of heat pump water heater
Compared to a solar water heater, depending on the sun, the heat pump water heater works well all year, if the room temperature is not too low. Indeed, the operation of a heat pump depends on the heat available in the air and not sunshine.
In addition, the heat pump water heater allows you to make up to 70% savings. The coefficient of performance or COP of the heat pump is on average 4 to 1 kilowatt absorbed, it produces four kilowatts!
Finally, a thermodynamic water heater is easy to install.
