What is a thermodynamic water heater?
The thermodynamic water heater uses an integrated heat pump to heat water. It captures calories from the ambient air and consumes up to 3 times less energy than a traditional electric boiler.
How does it work?
- Capture: A fan draws ambient air through an evaporator
- Compression: A compressor raises the refrigerant temperature
- Transfer: Heat is transferred to the water via a condenser
- Expansion: The refrigerant cools and the cycle restarts
Advantages
- 50 to 70% reduction in electricity consumption
- Savings of €250 to €400 per year
- Uses renewable energy
- Eligible for energy subsidies
