What is a heat pump boiler?
An warmtepompboiler is specially designed for heating domestic water. In this process, heat energy is extracted from the outside air or from the inside air of an unheated room. This makes a heat pump water heater a very energy-efficient solution. For example, a heat pump water heater is 3 to 4 times more economical than an ordinary electric water heater, making it a good alternative to all conventional water heating systems.
How does a heat pump boiler work?
Unlike traditional water heating systems, which rely entirely on fossil fuels or electricity, a heat pump boiler uses only partial electricity. In fact, about 70% of the energy required is obtained from ambient air.
The system works by using ambient heat from indoor air, outdoor air or ventilation air, where a coolant boils at a low temperature and becomes gaseous. The gas formed is then compressed to raise the temperature, then the heat is released to the domestic water. An electric reheater can further heat the water above 55°C, if needed. Due to space requirements and noise levels, a heat pump boiler is usually installed in the garage or basement.
Tip: Shower during the day, a higher air temperature increases the efficiency of the heat pump boiler.
What are the benefits of a heat pump boiler?
There are many advantages to a heat pump boiler.
- In the medium term, it is much cheaper than a boiler running on electricity or gas. Especially since electricity and gas prices have never been higher.
- It is possible to recoup this heat pump boiler in one year under ideal circumstances. Here again the prices of gas and electricity play a big role.
- You can connect a heat pump boiler to solar power.
- Installation is simple and does not create dirt.
- Suitable for homes without a gas connection
- A heat pump boiler increases the EPC score and thus makes your home more energy efficient. That's why there are incentives and subsidies available if you install a heat pump boiler.
What are the disadvantages of a heat pump boiler?
There are not many disadvantages to a heat pump boiler. Still, there are a few.
- In fact, it takes up more space than an electric water heater since it has a heat pump installed.
- It is also sometimes necessary to provide exhaust air. That with small spaces. Want to avoid that? Then the garage, attic or basement are the perfect places to install a heat boiler.
How much does a heat pump boiler cost?
AeroConsult offers heat pump boilers with cost 2625 euros - 6873 euros. You can choose to do the installation yourself or have it installed by professionals.

Is a heat pump boiler cost-effective?
With a heat pump water heater, you can make significant annual savings compared to an electric water heater. Smart use of ambient heat can reduce energy consumption by as much as two-thirds. This makes the heat pump boiler not only a sustainable choice, but also a very profitable long-term investment.
When is a heat pump a good choice?
- As a replacement for an electric water heater, even if the electric water heater is still working, a heat pump water heater provides a quick payback thanks to higher energy efficiency.
- When your home has no gas connection, because the system uses ambient air to heat water.
- When your household needs a lot of domestic hot water,
- Or if your home has solar panels or if you are considering solar panels as self-consumption increases and energy costs continue to drop.
In short, a heat pump water heater is energy-efficient and environmentally friendly, especially advantageous as a replacement for an electric water heater, in the absence of gas, for high hot water demand and in combination with solar panels.
Grants and subsidies heat pump boilers
The Flemish government has a general premium that includes everything around remodeling: My Remodeling Premium. That premium also includes the purchase and installation of a heat pump boiler. How high this premium is depends very much on your home, your income and your family situation. So it is best to read up on the site of the Flemish Government.
