Learn what a thermodynamic water heater is and how it works
Thermodynamic water heater: less impact on the environment, more savings
The thermodynamic water heater is currently one of the most efficient solutions for producing domestic hot water in an environmentally friendly and economical way. Thanks to its integrated heat pump, it draws heat from the ambient air to heat the water. This system not only significantly reduces electricity consumption, but also limits greenhouse gas emissions. More and more households in Belgium are opting for this sustainable alternative, which combines energy efficiency with environmental friendliness.
The operation of a thermodynamic water heater
The thermodynamic water heater is based on the principle of aerothermal energy. It is equipped with a heat pump that captures calories from the air (indoor, outdoor or extracted from a CMV) and transfers them to a hot water tank via a refrigerant. This process heats the water using much less electricity than a conventional electric water heater. The system operates independently, with a thermostat to regulate the temperature and an electric backup that is activated when necessary, particularly during periods of high consumption or very low outdoor temperatures.
The different types of thermodynamic water heaters
There are several models of thermodynamic water heaters, adapted to the needs and configuration of each home:
Ambient air: The most common type, it captures heat from the air in the room where it is installed, usually a garage or utility room.
Outdoor air: It is connected to ducts to draw in air from outside the building. Ideal when the installation room is too cold or poorly ventilated.
On extracted air (CMV): Connected to a controlled mechanical ventilation system, it recovers heat from the air extracted from damp rooms. This is a highly effective solution in low-energy buildings or very well-insulated homes.
Each type of water heater has specific advantages depending on the installation conditions and the desired level of performance.
Thermodynamic water heater: installation
The installation of a thermodynamic water heater must be carried out by a qualified professional to ensure optimal performance. Several criteria must be taken into account: the volume of the tank, the location, ventilation, access to an air source (indoor, outdoor or CMV), and noise level. The tank is usually installed in an unheated but well-ventilated room, such as a garage, basement or laundry room. In Belgium, certain regional subsidies may cover part of the installation cost, particularly in Wallonia and Brussels. Calling on a specialist such as Frigotec ensures that the installation complies with standards and is perfectly suited to your home.
The thermodynamic water heater: 30 seconds to understand
The thermodynamic water heater works in the opposite way to a refrigerator: it captures heat from the air to heat water. This system uses up to three times less electricity than a conventional electric water heater. It is environmentally friendly, economical and sustainable, and has become the preferred choice for reducing energy bills while contributing to the ecological transition.
Advantages of the thermodynamic water heater
The benefits of this system are numerous, both in terms of the economy and the environment:
Up to 70% energy savings compared to an electric water heater.
Reducing CO₂ emissions: a solution in line with climate objectives.
Eligible for financial assistance: regional grants, reduced VAT, tax deductions.
Consistent comfort: hot water production even during periods of high demand.
Extended lifespan with: with regular maintenance, the system can last more than 15 years.
Thanks to these advantages, the thermodynamic water heater appeals just as much to private individuals as to professionals. a9> private individuals as well as professionals.
Installing a thermodynamic water heater: what you need to know
Before proceeding with installation, a thermal assessment of the dwelling is strongly recommended. It is also necessary to check that the available space meets the manufacturer’s requirements, particularly in terms of volume and ventilation. Installation includes fitting the tank, electrical connections, hydraulic connections, and sometimes integration with an existing CMV system. The professional will also make the necessary adjustments to optimise energy consumption and ensure the system is working properly.
