Answer: it is a domestic hot water tank coupled to a miniature heat pump.
The thermodynamic water heater is actually a domestic hot water tank topped with a miniaturized heat pump. This particular heat pump uses heat from the air in the room in which it is located, preferably a room that is always very hot, such as the laundry room or the room containing the boiler, to produce hot water. It therefore does not depend on the external conditions, but on the heat emitted by your household appliances. The thermodynamic water heater is a very clever system which re-uses, recycles it can be said, a heat which is normally lost. In addition, its coefficient of performance is 4: it produces four times more energy than it consumes. Which gives access to the tax credit. Ideal for saving energy, without installing a complicated system or having to do costly work, as in the case of a conventional heat pump. You too, send us your brico question
