Electric boilers
Electric boilers are compact heat generators for heating systems that are powered by electricity and can be used as the main heating system, supplementary heating, or as a transitional solution depending on the system design. They are particularly suitable for applications where simple integration into a water-based heating system is desired.
In the GEMA Shop you will find electric boilers for various power ranges, installation situations, and system requirements – suitable for renovation, expansion of existing systems, or special technical solutions.

Choosing the right electric boiler
Electric boilers are electrically operated heat generators for water-based heating systems. They convert electrical energy into heating heat and, depending on the system concept, can be used as a standalone heating system, supplementary heating, emergency heating, or transitional solution. Electric boilers are particularly interesting where no conventional fuel is to be used or where a compact, comparatively easy-to-integrate heating solution is required.
Unlike wood, pellet, or gas heating systems, electric boilers do not require a fuel storage room, flue gas routing, or a chimney connection. However, a suitable electrical connection capacity and a professionally planned integration into the heating system are crucial.
Advantages of electric boilers
- Compact design: Electric boilers require little space and can often be easily integrated into utility rooms.
- No flue gas routing: Since no combustion takes place, no chimney or flue gas system is required.
- Flexible system integration: Depending on the system, electric boilers can be used as the main heat generator, supplementary heating, or backup solution.
- Low-maintenance technology: Without a burner, fuel storage, and combustion process, the technical setup is comparatively straightforward.
Areas of application and target groups
Electric boilers are suitable for homeowners, DIY builders, buyers close to the SHK trade, and technically interested customers who are looking for an electricity-based heating solution. Typical areas of application are smaller buildings, additions to existing heating systems, transitional solutions, holiday homes, workshops, or systems where an additional heat generator is needed.
Important selection criteria for electric boilers
When selecting an electric boiler, the rated output, voltage, phases, fuse protection, power consumption, connection type, electronic control, maximum flow temperature, and energy efficiency class should be considered above all. For sensible system integration, buffer tanks, control technology, heating accessories and system technology or suitable Heating elements be relevant.
Note on sizing
The output of an electric boiler must match the building, heat demand, electrical connection, and system concept. Information on output classes or areas of application is only for initial orientation and does not replace a professional heat load calculation, electrical inspection, or system planning.
Frequently asked questions about electric boilers
What is an electric boiler?
An electric boiler is an electrically operated heat generator for water-carrying heating systems. It generates heating heat with electricity and transfers it to the heating water in the system.
Who is an electric boiler suitable for?
An electric boiler is suitable for customers looking for a compact electricity-based heating solution. Depending on the system, it can be used as a main heating system, supplementary heating, emergency heating, or transitional solution.
Does an electric boiler require a chimney?
No, an electric boiler does not require a chimney or flue gas routing, as no combustion takes place. Instead, a suitable electrical connection is important.
What output should an electric boiler have?
The appropriate output depends on the building's heat demand, the heating system, the insulation standard, and the desired area of application. The sizing should be carried out professionally and not decided solely based on living space.
Can an electric boiler be combined with a buffer tank?
Yes, depending on the system design, an electric boiler can be combined with a buffer tank. A buffer tank can help provide heat and integrate the system hydraulically in a sensible way.
Which electrical requirements are important?
Important aspects include voltage, phases, fuse protection, connection type, and available connected load. These points must be checked by a qualified specialist before installation.
Are electric boilers eligible for funding?
Whether an electric boiler is eligible for funding depends on the specific product, the system design, and the currently applicable funding conditions. Funding guidelines should always be checked for current validity before purchase and installation.
