Are you looking for an efficient way to heat your home sustainably while saving costs? A hybrid heat pump combined with a central heating boiler can offer a solution. This combination provides environmentally friendly heating and lowers your energy bill. In this guide, we explain exactly what a hybrid heat pump is, how the system works with the central heating boiler, and what benefits it offers for your home in 2026.
What is a hybrid heat pump and how does it work with the central heating boiler?
A hybrid heat pump is a system that extracts electrical heat from the outside air and combines it with a traditional gas-fired central heating boiler. This system ensures that the heat pump does most of the work, especially at mild outdoor temperatures. When it gets colder outside and the heat pump is less efficient, the central heating boiler kicks in to provide sufficient heat. This collaboration makes the hybrid heat pump profitable and practical, especially for existing homes where a complete switch to electric heating might still be challenging.
The basic principles of a heat pump
A heat pump extracts heat from natural sources such as air, soil, or water. The principle is similar to that of a refrigerator, but in reverse: a refrigerator extracts heat from inside and releases it outside; a heat pump extracts heat from outside and brings it inside. The heat pump uses electricity to move this heat, with its efficiency expressed as the Coefficient Of Performance (COP). This means that multiple times more heat is generated with a low amount of electricity. The annual average efficiency, the SCOP, indicates the energy efficiency over an entire heating season. Thus, a good heat pump delivers significantly more heat than the electrical energy consumed, contributing to a lower energy bill.
Types of heat pumps: hybrid versus all-electric systems
Hybrid heat pumps combine electric heating with the existing central heating boiler, while all-electric heat pumps operate without gas heating. A hybrid heat pump is particularly suitable for homes with moderate insulation and where full electrification is not yet possible. All-electric heat pumps are better suited for well-insulated homes with low-temperature heating such as underfloor heating. In addition, hybrid systems usually only provide heating, while all-electric heat pumps often also supply hot water. In terms of cost, a hybrid system is often cheaper to purchase and install due to the existing central heating boiler.
How a hybrid heat pump works with the central heating boiler
The hybrid system operates based on temperature and demand. At mild outdoor temperatures, the heat pump provides the main heating by extracting heat from the air and distributing it through the water circuit. When it gets colder or there is a higher heat demand, the central heating boiler supports the heat pump. The heat pump delivers water at temperatures around 35-55 °C, while the central heating boiler can deliver higher temperatures up to 70 °C. This makes the system flexible and reliable, without the resident having to sacrifice comfort. Compared to all-electric systems, which always provide full heating, the hybrid system offers practical advantages, especially in varying weather conditions.
What types of hybrid heat pumps are there?
Hybrid air/water heat pump
This is the most common type of hybrid heat pump in the Netherlands. It extracts heat from the outside air via an outdoor unit and heats water that heats the home via an indoor unit or heat pump boiler. Within these systems, there are direct delivery systems, where the heated water goes directly to radiators or underfloor heating, and indirect systems that first heat a storage tank. Direct systems are generally more efficient because less heat is lost.
Other hybrid systems briefly mentioned
In addition to air/water heat pumps, there are also ground source heat pumps and ventilation heat pumps that can function in a hybrid manner. Ground source heat pumps use heat from the ground, which is a more stable heat source but often requires a more expensive installation. Ventilation heat pumps utilize heat from ventilation air but are less common as a hybrid solution. Of these options, the air-source heat pump is by far the most popular due to its relatively simple installation and wide applicability.
Advantages of a hybrid heat pump in combination with a central heating boiler
A hybrid heat pump can reduce gas consumption by approximately 60%, leading to significant cost savings. This also significantly reduces CO2 emissions, contributing to sustainable heating of your home. The investment is lower than for all-electric systems because the existing central heating boiler remains functional. This makes it ideal for existing homes with limited insulation, where a complete switch to electric heating is not yet feasible without extensive modifications.
What does the purchase and installation of a hybrid heat pump cost?
The average costs for the purchase and installation of a hybrid heat pump including a central heating boiler range between €5,000 and €10,000. This amount can vary depending on the type of home, insulation level, and whether a hot water boiler needs to be added. It is also possible to use subsidies and tax benefits that make the investment more attractive. Due to gas and energy savings, the payback periods average 5 to 8 years, depending on energy costs and usage.
How does heat pump savings work with the central heating boiler?
In a hybrid system, the heat pump provides the main heating, and the central heating boiler primarily assists during peak demand. This means you can save an average of about 60% on gas. The exact savings depend on the insulation and heating needs of the home. Factors such as the SCOP and annual efficiency determine the level of efficiency and actual energy consumption. Good insulation and adjusted usage ensure optimal savings.
Is my home suitable for a hybrid heat pump?
Hybrid heat pumps are often well-suited for homes built before 1990 with basic insulation, such as roof, wall, and floor insulation combined with HR++ glass. For optimal performance, it is important that the home has good ventilation. The heat emission system – radiators or underfloor heating – can have an impact; for older radiators, adjustments or additional layers of insulation are often needed. It is wise to prepare your home well to meet the heating demand and thus maximize efficiency.
Heat pump and comfort: does a hybrid heat pump provide sufficient heat?
A hybrid heat pump typically delivers water at lower temperatures than a central heating boiler, which is sufficient for well-insulated homes or in combination with underfloor heating. On cold days, the central heating boiler supports the system to maintain comfort. Many users even experience a higher level of comfort due to the constant, even heat distribution and the environmentally friendly operation of the system.
Noise pollution and placement of the outdoor unit
The outdoor unit of a hybrid heat pump produces noise, similar to a quiet fan. Smart placement is crucial to minimize noise pollution, for example, by maintaining distance from neighbors' bedrooms or by implementing sound-absorbing measures. Legal noise standards ensure that the noise remains within acceptable limits. Vibrations can be reduced with special base mounts and anti-vibration brackets.
Refrigerants in hybrid heat pumps: impact and developments
Refrigerants are essential for transferring heat within heat pumps. There are synthetic refrigerants, which often have a higher Global Warming Potential (GWP), and natural refrigerants like propane, with minimal environmental impact. Heat pumps with natural refrigerants offer more environmentally friendly alternatives, which is increasingly encouraged by new regulations and technological developments focused on sustainability.
Heat pump and hot water production: collaboration in a hybrid system
In hybrid systems, the central heating boiler usually provides domestic hot water because the heat pump system often produces lower temperatures. Looking to the future, systems are being developed where the heat pump can also partially supply hot water, which can further reduce energy consumption. Comfortable hot water supply remains important for users. Each solution has pros and cons in terms of energy use and installation complexity.
Installation process of a hybrid heat pump
Installation begins with a technical inspection where a professional assesses the home. Based on this, the correct equipment is chosen and planned for placement.
