- How It Works
How does an
air-to-water heat pump work?
An air-to-water heat pump extracts heat from the outside air and uses it to heat water for your central heating system (and domestic hot water).
Because a heat pump transfers heat rather than generating it, it is highly energy-efficient. Its efficiency is highest in well-insulated homes with low-temperature heating systems, such as radiant floor heating.
- Ideal for new construction or renovation
- To replace a combustion boiler that heats radiators
- Works efficiently with radiant floor heating
- Why?
What are the benefits of an
air-to-water heat pump?
A ground-water heat pump is one of the most efficient heat pumps available on the market.
Lower installation cost
An air-to-water heat pump draws energy from the outside air, eliminating the need for drilling or excavation. This saves you thousands of euros in installation costs.
Low energy costs
A heat pump produces 3 to 5 kWh of heat for every kWh of electricity. As a result, your heating costs will be significantly lower in the long run than with a gas boiler.
Silent as a whisper
Because there is no outdoor unit with a fan, the system operates virtually silently. This enhances living comfort and prevents noise pollution.
Increase in Home Value
A heat pump significantly contributes to a lower EPC score. This has a major impact on the home's market value.
Cooling capability
Many systems provide active or passive cooling during hot periods. This improves thermal comfort without the need for a separate air conditioning system.
Safety
The absence of a combustion process eliminates risks such as CO formation. In addition, maintenance requirements are generally lower than with traditional boilers.
- Investment
How much does an air-to-water heat pump cost?
The investment required for an air-to-water heat pump is generally considerably lower than that for a ground-to-water heat pump, because no drilling or excavation is required. Due to this lower initial cost, the payback period is usually more favorable as well.
The average price of an air-to-water heat pump ranges from €10,000 to €20,000. It’s important to note that subsidies are currently available. These subsidies can significantly reduce the net investment, thereby shortening the payback period.
Factors that influence the price:
- Heat Pump Capacity
- Dispensing System
- Integration of Domestic Hot Water
- How It Works
The real savings come from energy consumption
A heat pump draws most of its energy from the environment (air, ground, or water) and therefore consumes much less primary energy than, for example, a gas condensing boiler. Its efficiency is expressed as the COP or SCOP: the higher this value, the more heat you get on average per kWh of electricity consumed.
In addition, electricity is becoming structurally cheaper, while gas is becoming more expensive due to Flemish and European policies. Examples include the Flemish tax shift, ETS2, additional excise taxes, …
- Gas prices will rise steadily starting in 2028
- Electricity will become cheaper
- Europe aims to phase out gas entirely over time
- Compatibility
Integration with your point-of-sale systems
An air-to-water heat pump operates most efficiently at low supply temperatures, but can be combined with various heat distribution systems.
Radiators
Modern heat pumps can be used with your existing radiators. We offer heat pumps that can reach a flow temperature of up to 70°C, allowing you to keep your existing radiators.
- High delivery temperature possible up to 70°C
- No additional replacement cost
- Less efficient than radiant floor heating
Floor heating
Underfloor heating is the most efficient system to pair with a heat pump, thanks to its low water temperatures and even heat distribution. This results in maximum seasonal efficiency, a stable indoor climate, and lower energy consumption.
- High efficiency and maximum performance
- High comfort thanks to gentle radiant heat
- No visible heating elements
Convector Heaters
- 1-for-1 replacement without demolition work
- Almost as efficient as radiant floor heating
- High cooling efficiency

- 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.
- Premiums
Get a rebate for your air-to-water heat pump
Did you know that in Belgium you can receive subsidies for installing an air-to-water heat pump? In addition, in most cases, the VAT rate on heat pumps is currently reduced to 6%, which makes the investment even more attractive.
The amount of the premium depends on your income and the region where you live:
- "My Heat Pump" Incentive (Flanders) up to €4,800
- RENOLUTION Incentive (Brussels) up to €4,500
- Home Insurance Premiums (Wallonia) up to €3,600

Get even more out of your heat pump
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.
Dynamic energy contract
A heat pump can be intelligently controlled based on dynamic electricity prices. The system provides additional heating during off-peak hours and reduces energy consumption when electricity is more expensive. This optimizes your overall efficiency.
