A hybrid heat pump combines an electric heat pump with a gas-powered boiler. The system primarily heats your home with electricity and extracts heat from the outside air. The boiler only kicks in on cold days or for hot water. This saves up to 70% on gas consumption and reduces CO₂ emissions by about 30%.
Main points:
- Cost savings: Annual savings of €750 to €2,000 on energy costs.
- Sustainable: Less dependent on gas, especially with solar panels.
- Installation: Requires good insulation, costs range from €6,000 to €11,000 (subsidy available).
- Flexible system: Works efficiently at temperatures above 4°C and automatically switches between the heat pump and boiler.
- Future-proof: Ready for hydrogen and smart energy grids.
A hybrid heat pump is an ideal choice if you want to make your home more sustainable without major renovations. It offers a good balance between cost, efficiency, and environmental benefits.
How does a hybrid heat pump work?
A hybrid heat pump combines two heating systems: an electric heat pump and a gas-fired boiler. Using smart sensors, the system determines which method is most efficient at any given time, depending on the outside temperature and the heat demand in the home.
At mild temperatures (above approximately 4°C), the electric heat pump takes most of the workload. It uses heat from the outside air and brings it inside. The efficiency of a heat pump can reach up to 300%, meaning it generates three times as much heat as the amount of electricity it consumes.
Below you will read more about how the hybrid heat pump works and which components play a role in it.
Main components of a hybrid heat pump
The operation of a hybrid heat pump revolves around several key components:
| Component | Function |
|---|---|
| Heat pump unit | Ensures heat transfer during heating and cooling. |
| Boiler | Activates when the heat pump is less efficient. |
| Thermostat | Controls the system and automatically switches between heat pump and boiler. |
| Refrigerant | Transfers heat within the heat pump. |
| Air handling unit | Distributes warm or cool air throughout the home. |
The heat pump unit, usually located outside, contains an evaporator and a compressor. This unit extracts heat from the outside air and transports it via the refrigerant into your home. The boiler acts as a backup and steps in when the heat pump becomes less effective. The thermostat is the central switch that continuously analyzes the outside temperature and heat demand to determine which system to deploy.
How does the system switch between energy sources?
The hybrid system uses advanced sensors and algorithms to determine which heating source is most suitable. The thermostat continuously monitors the outside temperature and compares the performance of the heat pump with that of the boiler.
At temperatures above 4°C, the heat pump is used due to its high efficiency in producing heat. As the temperature drops further, the heat pump becomes less efficient. At that point, the system calculates the tipping point and automatically switches over to the boiler.
"A hybrid heating system monitors the outside temperature and automatically chooses the most energy-efficient option to keep your house consistently warm and your water hot." - National Grid
This transition happens seamlessly, without you noticing it. In summer, the heat pump functions as an air conditioner: it expels heat from your house to the outside, keeping your home pleasantly cool.
Why choose a hybrid heat pump in the Netherlands
In the Netherlands, more and more households are opting for hybrid heat pumps due to their benefits in cost savings, lower CO₂ emissions, and preparation for future energy needs. These systems combine the efficiency of a heat pump with the reliability of a boiler. Let's look at the main advantages.
Lower energy costs and increased efficiency
A hybrid heat pump can reduce your gas consumption by up to 70%, leading to annual savings of €750 to €2,000. Especially in winter, this system can lower your heating costs by about 25% compared to a traditional boiler.
The secret lies in its operation: instead of generating heat by burning fuel, a heat pump uses electricity to transfer heat. At temperatures above 4°C, the heat pump can deliver up to four times more heat per unit of electricity consumed.
To give an idea: with a hybrid heat pump, you can save more than €1,000 annually. By combining this system with solar panels, you directly utilize your self-generated power, further lowering your energy bill.
Lower CO₂ emissions
In addition to financial benefits, a hybrid heat pump also helps the environment. Because these systems primarily use electricity – increasingly sourced from wind and solar energy – they emit significantly less CO₂ than a traditional boiler. Even if part of the electricity is still generated with natural gas, the total emissions remain lower.
The Dutch energy policy encourages the use of hybrid systems, partly because they put less pressure on the electricity grid. Minister Rob Jetten of Energy emphasized this advantage:
"Hybrid systems allow users to switch between gas and electricity and are therefore less burdensome for the electricity grid – hybrid systems can switch to gas at times of peak electricity grid demand if necessary to maintain security of electricity supplies."
An investment in the future
Although the mandate for hybrid heat pumps from 2026 has been canceled, they remain a smart choice. They prepare your home for future energy developments and already offer significant savings, with an average annual cost reduction of about €1,000 compared to traditional heating systems.
For many Dutch households, a hybrid heat pump offers the perfect combination of sustainability, lower costs, and ease of use. It's an investment that pays off, both in your wallet and for the environment.
Installation requirements and costs
Having discussed the operation and benefits, it's time to look at the installation requirements and costs. If you are considering installing a hybrid heat pump, it is essential first to check if your home is suitable. Proper preparation ensures that your heat pump operates efficiently and lowers your energy bill.
Home insulation and current heating systems
A hybrid heat pump operates optimally in a well-insulated home. Without sufficient insulation, much heat is lost, negatively affecting both operation and energy savings.
Although hybrid heat pumps have less strict insulation requirements than fully electric systems, it is important that your home meets some minimum insulation values:
- Cavity wall insulation: R-value of at least 4.5 (m²·K/W)
- Floor insulation: R-value of at least 3.5 (m²·K/W)
- Roof insulation: R-value of at least 6.0 (m²·K/W)
- Double glazing or better: At least HR++ (U ≈ 1.2 W/m²K) or triple glazing (U ≤ 0.8 W/m²K)
Homes built after 1995 usually meet these requirements. For older homes, it may be necessary to take insulation measures first. Additionally, good airtightness is important to further limit heat loss.
Once your home meets these conditions, you are ready to consider installation costs and subsidies.
Installation costs and available subsidies
The cost of a hybrid heat pump depends on the power and complexity of the installation. For a 4 kW heat pump, the costs range between €6,000 and €8,500. If your boiler also needs replacement or if modifications to your fuse box or heating system are necessary, the price can rise to €11,000.
Fortunately, the Dutch government provides financial support through the Investment Subsidy for Sustainable Energy (ISDE). This subsidy, managed by the RVO, ranges from €500 to €2,500, depending on the type and capacity of the heat pump.
| Subsidy Component | Amount in 2025 |
|---|---|
| Basic subsidy air-water heat pump | €1,250 |
| Subsidy per kW capacity | €225 |
| Bonus for A+++ energy label | €200 |
Note: the subsidy applies exclusively to the purchase of the heat pump and not to labor costs. Also, consider possible waiting times due to large demand for hybrid heat pumps.
Finding certified installers
Correct installation is essential to get the most out of your hybrid heat pump. Make sure you choose a certified installer who complies with the NEN 7120 standard. This standard ensures the quality of heat pump installations in the Netherlands.

A hybrid heat pump can be a valuable investment, but to get the most out of it, proper maintenance is essential. Without regular maintenance, your system’s efficiency can decrease by 10–25%, while a well-maintained heat pump can last up to 30 years. Maintaining your heat pump is therefore beneficial for both performance and lifespan.
The maintenance of a hybrid heat pump consists of two parts: tasks you can do yourself and tasks that a professional must perform. By carrying out both properly, your system will continue to function optimally. After installation, consistent maintenance is crucial to maintain your heat pump's performance.
Regular maintenance tasks
Professional maintenance should occur annually, preferably in the fall before the cold winter months. During this maintenance visit, a certified technician checks the refrigerant, cleans the coils, and tests the operation of all components. A standalone maintenance visit usually costs between €150 and €220, while a maintenance contract can cost between €10 and €25 per month. Call-out charges are usually between €50 and €70, with an hourly rate of about €50.
| Maintenance Task | Frequency | Responsible |
|---|---|---|
| Clean/replace filter | Every 60 days | Owner |
| Remove obstructions | As needed | Owner |
| Visual inspection | Regularly | Owner |
| Professional check | Annually | Technician |
| Clean coils | As needed | Owner/Technician |
| Glycol check | Annually | Technician |
For the maintenance tasks you can perform yourself, it is important to keep the outdoor unit free from leaves, snow, and other obstructions. This ensures optimal air circulation. Regularly check for possible leaks from the pipes and see if all components are in good condition. Also occasionally test your thermostat and other controls to make sure everything is working properly.
Using smart thermostats
Besides regular maintenance, technology can play a major role in making your hybrid heat pump more efficient. A smart thermostat can help reduce energy consumption, with savings of 8–15% on your heating and cooling costs.
Smart thermostats adapt to your daily routines. They, for example, automatically lower the temperature when you are not home and increase it again when you return. With a wifi connection, you can control the thermostat remotely and monitor your system's performance in real-time.
Optimally programming temperature differences is key to energy savings. According to the US Department of Energy, a temperature difference of 7–10 degrees over eight hours a day can yield about 10% energy savings. This helps your hybrid heat pump efficiently switch between the heat pump and the boiler.
Many modern smart thermostats also offer energy consumption reports, providing insights into your usage patterns. They can also work with other smart devices in the home, such as voice assistants and automated routines. Make sure your thermostat is compatible with your hybrid system and that your wifi connection is stable enough.
Preparing for future energy changes
The Dutch energy sector is on the brink of major changes. Hybrid heat pumps are seen as a transition technology that flexibly responds to developments in the energy landscape. By investing in a hybrid heat pump, you prepare your home for the future.
The government aims for an energy system where district heating, electric heat pumps, and hybrid heat pumps each account for about a third of the energy supply. This highlights that hybrid systems have a lasting place in the Dutch energy system.
Furthermore, hydrogen plays an important role in the future energy mix. Technologies such as hydrogen are increasingly being developed, and hybrid heat pumps align seamlessly with this.
Compatibility with future hydrogen boilers
Hydrogen is seen as a promising energy carrier, especially for homes where full electrification is difficult. Hybrid heat pumps can already handle green gas, including hydrogen, preserving the value of your investment in the future.
A major advantage of hybrid systems is their flexibility. The gas component can easily switch to hydrogen in the future without needing to replace the entire system. This makes hybrid heat pumps a smart choice for many Dutch households.
According to Energy Minister Rob Jetten:
"Hybrid systems allow users to switch between using gas and electricity and are therefore less burdensome for the electricity grid – hybrid systems can switch to gas at times of peak electricity grid demand if necessary to maintain security of electricity supplies." - Rob Jetten
The government supports this technology with subsidies, ensuring that from 2024, at least 100,000 heat pumps can be installed annually. Additionally, grid operators aim to install approximately 2 million (hybrid) heat pumps by 2030, focusing on existing homes.
Integration with smart energy grids
Apart from the integration of hydrogen, smart network technology plays an important role. Smart energy grids are becoming increasingly important as more households switch to electric heating. An all-electric house can peak at five times the consumption of a traditional home. In a future with many heat pumps, electricity demand can even be 10 to 20 times higher than now.
Hybrid heat pumps can meet this challenge through their flexibility. They use smart grids to consume energy when prices are lower. This happens automatically via intelligent control, where the heat pump and boiler work together optimally. A FAN report shows that 94% of the heat pumps sold in the Netherlands in 2021 are compatible with smart systems.
For optimal integration, you might consider an Energy Management System (EMS). This system aligns the energy flows from solar panels, charging stations, batteries, and your hybrid heat pump, thereby making your energy consumption more efficient.
| Preparation | Action | Timeframe |
|---|---|---|
| Communication standard | Check whether your heat pump supports the S2 standard | Upon purchase |
| Energy Management | Install an EMS system | Within 2 years |
| Network connection | Ensure a stable wifi connection | Immediately |
The S2 standard is essential because it ensures open communication between different devices. This simplifies integration and ensures safety.
Energy flexibility, or the ability to adapt your energy consumption without compromising comfort, is becoming increasingly important. Hybrid heat pumps offer this flexibility as they can switch between energy sources based on price and availability.
This flexibility is not only beneficial for households but also for the broader energy transition in the Netherlands. The government emphasizes that network limitations should not hinder housing targets. Hybrid systems help relieve pressure on the electricity grid, especially during peak times. This, they play a strategic role in the Dutch energy transition.
Is a hybrid heat pump suitable for your home?
Not every home is suitable for a hybrid heat pump. It is important to consider insulation, your current heating system, costs, and maintenance before making a decision.
Insulation and the current heating system are crucial. Homes that are already insulated or where insulation work has been carried out often benefit the most from a hybrid heat pump. A well-insulated house requires a smaller heat pump, which lowers both purchase costs and energy consumption.
The financial aspect is also an important consideration. The cost for a complete hybrid system ranges from €6,000 to €11,000, depending on whether you also replace your boiler. An example is the WeHeat hybrid heat pump, which costs approximately €5,199 including installation. Thanks to subsidies, you can recoup an average of 30% of the purchase costs, which amounts to between €500 and €2,500. Although the initial investment can be substantial, these costs are often recovered through lower energy bills.
Energy saving is one of the biggest benefits. With a hybrid heat pump, you can reduce your gas consumption by up to 60%, which can annually save €750 to €2,000 or more. ABN Amro estimates that this can save you up to 62% per month on your energy costs.
Maintenance and operational costs should also be part of your decision. Besides installation, there are annual maintenance costs. However, these costs are almost always outweighed by energy savings.
Practical matters also play a role. Besides insulation and costs, you must also consider the technical requirements for installation. If your piping system does not have sufficient capacity, replacement may be necessary. This can range from €1,000 to €5,000 to ensure the heat pump works optimally.
It is wise to hire an HVAC specialist for a comprehensive evaluation of your home. Such a specialist can advise on the suitability of a hybrid heat pump and any insulation measures needed to improve efficiency.
Hybrid heat pumps are especially suitable for homes with a reasonable to good insulation level and an existing boiler system. They offer the opportunity to take advantage of low electricity prices while gas serves as a reliable backup during cold days.
