A heat pump water heater is a water heater that uses ambient heat instead of electricity. But what exactly is a heat pump water heater? How much does something like this cost? And is it even cost-effective? AeroConsult lays it all out.

What is a heat pump boiler?

A heat pump boiler is specifically designed to heat domestic water. It uses heat energy from the outside air (or the air inside an unheated room) to warm the water. This makes the heat pump water heater a very energy-efficient solution. It is 3 to 4 times more efficient than a regular electric water heater.

How does a heat pump boiler work?

The system works by using ambient heat from indoor air, outdoor air or ventilation air, where a low-temperature coolant boils and becomes gaseous. This gas is compressed to raise the temperature, then heat is released to the domestic water. An electric post-heater ensures that the water is heated further if necessary, to above 55°C. Because of space requirements and noise, a heat pump boiler is often placed in the garage or basement.

What are the benefits of a heat pump boiler?

There are many advantages to a heat pump boiler.

  • First of all, in the medium term it is much cheaper than a water heater running on electricity or gas. Especially since electricity and gas prices have never been higher.
  • Another big advantage to a heat pump boiler in particular is that 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.
  • It is also possible to connect a heat pump boiler to solar energy.
  • Furthermore, the installation is simple and does not cause dirt.
  • Finally, a heat pump boiler raises the EPC score and thus makes your home more energy efficient. This is precisely 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.

Is a heat pump boiler cost-effective?

With a heat pump boiler, you save up to a lot of dollars in a year compared to an electric heat pump boiler. As shown earlier, a heat pump boiler is more energy efficient than an electric or gas-powered boiler: energy consumption drops by as much as two-thirds. So it is definitely a cost-effective solution.

When is a heat pump boiler a good choice?

A heat pump boiler is an excellent choice in the following situations:

  • 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.
