The thermodynamic water heater is increasingly popular in new homes as well as in renovation projects.
Today, we spend as much on heating our homes as we do on our hot water needs. Therefore, the search for savings is a key factor when choosing a new appliance. This is why the thermodynamic water heater is often chosen. It consumes much less energy than a conventional electric water heater.
We will look at the advantages and disadvantages of this product.
A thermodynamic hot water tank, sometimes called a thermodynamic cumulus or thermodynamic water heater, is a domestic hot water (DHW) production equipment. To operate, it is based on the principle of thermodynamics: it combines an aerothermal heat pump with a conventional water heater or hot water tank.
Like the latter, it produces hot water for all household needs: washing, cleaning (dishes), cooking… But, unlike them, it does not only use electricity to produce this hot water. It also extracts the calories present in the air to create heat and heat the water.
The ideal would be to set the temperature between 40 and 45°C. Indeed, it is unnecessary to have hotter water for your shower. In fact, the latest boiler models are all equipped with automatic anti-legionella programs and anti-corrosion and anti-scaling protection.
Here are the main advantages of this hot water production system:
– It is an economical device: it allows you to consume up to 3 times less energy than with a conventional electric water heater
– Its purchase price is affordable
– It is environmentally friendly: it takes advantage of a clean and inexhaustible energy. It does not emit any greenhouse gases into the atmosphere.
– Allows dehumidification of a room
Lowering the temperature of your hot water tank also helps save water. Indeed, to reach 38°C, the usual temperature for a shower, the hot water from the tank is mixed with cold water via a mixer tap. And the less hot the hot water is, the less cold water will need to be added to the mix to reach the ideal degree!
■ Air intake and exhaust in the boiler room
■ Use of heat emissions from heating
■ Air intake and exhaust in the adjacent room.
■ Installation in the boiler room with heat pump for heating (wine cellar, pantry, min. volume 25 m3)
■ Use of heat emissions from refrigeration and freezing appliances
■ Air intake and exhaust in the room
■ Dehumidified room
■ Use of heat emissions from the washing machine and dryer (laundry room, min. volume 20 m3)
■ Air intake and exhaust in the room or outside
■ If air duct as illustrated, the window can remain closed

For hot water production, the water heater with integrated heat pump CombiVal WPE/WPER/WPEF draws a large part of its energy for free from the ambient air, for example from the air in the room where the device is installed. The integrated heat pump extracts energy from this air to produce hot water, which allows to save up to two-thirds of energy costs.
Another interesting advantage: the expelled air can be used to cool and dehumidify a small room, such as a basement or a pantry.
