- How It Works
How does a heat pump water heater work?
A heat pump water heater is an energy-efficient solution for producing domestic hot water. While traditional systems run entirely on electricity or fossil fuels, this system draws most of its energy from the ambient air. This allows you to save up to 70% on energy compared to an electric water heater.
- Significant savings on your energy bill thanks to high efficiency
- Environmentally friendly solution
- Low initial cost and available premium options
- Why?
What are the benefits of a
heat pump water heater?
You'll lower your energy costs, increase your self-consumption of solar energy, and invest in a forward-looking, sustainable solution.
High energy efficiency
A heat pump water heater extracts heat from the ambient air and therefore uses much less electricity than a traditional electric water heater.
Low investment cost
With an investment of between €2,500 and €5,000, a heat pump water heater is significantly less expensive than a full-scale heat pump system.
Easy installation
In many homes, a heat pump water heater can replace an existing electric water heater without major renovations.
- For me?
When is a heat pump water heater a good option?
A heat pump water heater is a smart choice when
- You're replacing an electric water heater
- You want to reduce your energy consumption without replacing your heating system
- You don't have a separate hot water system, such as when your home is heated by an air-to-air heat pump
When combined with solar panels, you can increase your self-consumption of the electricity you generate and significantly shorten the payback period for your heat pump water heater.
- Premiums
Get a rebate for your heat pump water heater
Did you know that in Belgium you can receive rebates for installing a heat pump water heater? Depending on your location and income bracket, you may be reimbursed for a significant portion of your investment.
In addition, in most cases, heat pumps are currently subject to a reduced VAT rate of 6%, which makes the investment even more attractive.

Perfect service. We received clear information in advance, including a site visit from the project engineer. The installation went very smoothly, and in my opinion, the staff was very knowledgeable.
I am extremely satisfied with the service provided. This company is customer-friendly, helpful in finding appropriate solutions, and highly competent.
Last week, Energyking installed a charging station at our home. The installation took place at the agreed-upon time, and the staff were friendly and professional.
We are very satisfied with our partnership with EnergyKing. Jo gave us a very clear explanation. Even after the installation, EnergyKing is always there for us!
A company you can count on! Efficient scheduling, friendly service, clear information both over the phone and in person, and always available to answer questions.
I just had an air conditioner installed by Energyking. Very satisfied!! Efficient workflow. Installed perfectly, finished neatly—and all at a competitive price!
Fast and professional service, and a very customer-friendly company! Thanks, Brecht, Joren, and Jan!
Energyking just finished installing a ground-water heat pump. For a relatively young company, they show a lot of maturity! I definitely recommend them.
I had an air conditioner installed by the team at Energyking. From our first contact through to the installation, everything went smoothly. Very professional work.
Everyone was very friendly, both on the phone and the people who came to give me a quote. Whenever I had questions, they were always there to help. I’m very satisfied!
Until March 2023, there was a 200% tax credit for companies that installed charging stations. They installed 22 professional charging stations. High quality, fast, and at a great price!
We are very satisfied with the proper and precise execution of the work, the fulfillment of agreements, and the responses to our questions and comments.
We contacted several companies about installing a charging station. We chose EnergyKing because their quote was clear and communication was smooth.
We're very satisfied with this partnership. Communication went smoothly, and our solar panels were delivered quickly (compared to other companies)! Top-notch service.
I had a very pleasant experience working with EnergyKing, which was recommended by a friend. Clear communication, quick installation, and the quote and invoice were straightforward.
A top-notch experience from start to finish. They followed through perfectly on all agreements, promises, and timelines, with excellent communication! I’m really, really satisfied with this company!
Our solar panels were installed last December. The technicians were very friendly and worked efficiently. I am very satisfied with my installation.
From the initial consultation to installation and inspection, everyone involved was highly skilled and knew how to get the job done. It was a complete end-to-end process with excellent communication throughout.
- FAQ
Frequently Asked Questions About Heat Pumps
Can you cool a room with a heat pump?
Yes, both air-to-water and ground-to-water heat pumps can also cool your home in the summer.
- In an air-to-water heat pump, this is achieved through active cooling, during which the system operates in reverse mode.
- With a ground-source heat pump, passive cooling is often possible as well, utilizing the natural coolness of the ground.
Important to know: A heat pump’s cooling capacity is less intense than that of a traditional air conditioning system. You shouldn’t expect a temperature drop of 10°C, but rather a pleasant reduction of a few degrees, which is often enough to ensure comfort on hot days. It’s ideal when combined with underfloor heating or fan coil units that are also suitable for cooling.
Does a heat pump also work in combination with high-temperature heating systems?
Heat pumps are most efficient when used for low-temperature heating systems, such as radiant floor heating or modified radiators.
But we also offer high-temperature heat pumps with a supply temperature of up to 70°C. They’re ideal for replacing your gas or oil boiler and work perfectly with your existing radiators.
Please note: these systems may consume more electricity than standard heat pumps. When renovating, we’d be happy to work with you to determine whether your existing heating system is compatible or needs to be replaced.
Do I need a permit for a heat pump?
In most cases, you do not need a permit to install a heat pump in your home. There are, however, a few exceptions:
- In some cases, ground-water heat pumps (with vertical boreholes) require a notification or permit from the Flemish Environment Agency, because drilling takes place underground.
- Air-to-water heat pumps generally do not require a permit, but you must take noise standards into account (especially if the outdoor unit is located close to a property line).
In the case of new construction or major renovations, the heat pump must, of course, be included in the EPB report.
How loud is a heat pump?
The noise level of a heat pump depends on the type of unit and where it is installed:
- An air-to-water heat pump has an outdoor unit that makes noise, similar to an air conditioner. At a distance of 5 meters, the noise level is usually between 35 and 50 decibels (comparable to a soft murmur or a refrigerator). Inside, you generally won’t be bothered by the noise, since the indoor unit operates very quietly and is usually installed in a storage room or utility room.
- A ground-water heat pump operates almost silently because it does not require an outdoor unit.
Waiting...
It costs money!
- Mix and match smartly
Get even more out of your heat pump water heater
The payback period for a heat pump is strongly influenced by the cost of the electricity consumed. The lower your actual electricity rate, the greater the savings and the shorter the payback period.
Solar Panels
A heat pump runs entirely on electricity. By generating some of that electricity yourself with solar panels, you can significantly reduce your energy costs. In practice, this can save you about 25% on the total investment.
Home Battery
A home battery stores excess solar energy for later use. This allows your heat pump to run in the evening using solar energy you’ve generated yourself. This increases your self-consumption and lowers your energy costs.
