Heating systems
In the heating systems category, you will find modern and efficient heating solutions for various requirements and buildings. Whether it's a heat pump, pellet boiler, wood gasifier, gas condensing boiler, or electric boiler – here you will discover the right solution for your home.
Choosing the right heating system
Heating systems are the heart of any modern heat supply. In the GEMA Shop, you will find a wide range of heating systems for different requirements – from efficient heat pumps to pellet boilers and wood boilers to gas condensing units and electric boilers.
The decisive factors for choosing the right heating system are the heat demand of your building, the available fuel, the desired equipment, and the integration into the existing heating system. With the filters on this page, you will find the right solution for your project more quickly.
Differences between the heating systems
Heat pumps use environmental energy and convert it into heating heat. They are particularly suitable for well-matched heating systems, new buildings, and renovated buildings. Depending on the design, air-to-water, brine-to-water, or other types of heat pumps may be considered.
Pellet boilers and wood boilers use renewable fuels such as wood pellets or log wood. They offer a high degree of independence from fossil fuels and are particularly interesting when wood is to be deliberately used as an energy source.
Gas condensing units impress with their compact design and proven heating technology. Electric boilers can be a sensible addition, for example in certain existing installations, transitional solutions, or in combination with your own electricity generation.
The choice of the right system always depends on the structural conditions, the existing heating system, the desired comfort, and personal priorities.
Important selection criteria for heating systems
- Heating system: Heat pumps, pellet boilers, wood boilers, combi boilers, gas condensing boilers, or electric boilers differ significantly in technology, fuel, and area of application.
- Rated output in kW: The output must match the building, heat demand, and system concept.
- Output class: The classification helps narrow down suitable devices according to typical output ranges.
- Recommended area of application: Information on building size or living space serves as a guideline and does not replace a heat load calculation.
- Fuel or energy source: Depending on the system, electricity, wood pellets, log wood, gas, or combined solutions are possible.
- Subsidy status:Eligible products should always be checked in relation to the currently valid subsidy conditions.
System integration and matching components
Many heating systems require additional components so that they can be reliably and efficiently integrated into the overall system. Depending on the system, these include buffer tanks, domestic hot water tanks, control technology, pump groups, return temperature boosters, safety valves, chimney or flue gas components, and suitable installation material.
Especially with heating systems, the coordination between the heat generator, storage tank, hydraulics, control system, and the existing installation is crucial. Therefore, not only the individual boiler or the individual unit should be considered, but always the entire heating system.
Note on system design
The filter values on this page are intended as a guide for product selection. The specific design of a heating system should always be based on the actual building data, the heat demand, the existing heating system, and a professional heat load calculation.
Frequently Asked Questions about Heating Systems
Which heating system is right for my home?
The right heating system depends on the heat demand, the energy efficiency of the building, the existing heating system, the available fuel, and the desired comfort features. For new builds or renovated buildings, heat pumps can be an option, while pellet boilers, wood boilers, or gas condensing units can also be suitable solutions depending on the situation.
Which boiler is suitable for my building?
The suitable boiler depends on the building size, heat demand, existing hydraulics, fuel availability, and desired operating comfort. Pellet boilers usually operate more automatically, wood boilers require more manual operation, gas condensing units are compact, and electric boilers can be useful for special applications.
How do I find the right heating output?
The heating output is specified in kW and must match the actual heat demand of the building. A rough orientation via output classes or recommended application areas can help with the preselection. However, the final sizing should always be carried out via a professional heat load calculation.
Which heating system is eligible for subsidies?
Whether a heating system is eligible for subsidies depends on the specific product, the technical requirements, and the currently applicable subsidy conditions. Information on subsidy status in the shop is for orientation. Before purchasing, the current subsidy requirements and proof obligations should be checked.
What is the difference between the heating systems?
Heat pumps use ambient energy and electricity, pellet boilers run on wood pellets, wood boilers on log wood or other solid fuels, gas condensing units on gas, and electric boilers on electricity. The systems differ in fuel, operation, space requirements, system setup, and integration into the heating system.
Do I need a buffer tank?
A buffer tank is useful or required for many heating systems, especially for wood heating, pellet boilers, and certain system combinations. It absorbs heat, compensates for load peaks, and can make the heating system more hydraulically stable. Whether a buffer tank is needed depends on the heating system and the specific system design.
