Which heating system suits your building depends on several factors: building type, living space, insulation standard, existing heating system, desired fuel, space in the boiler room, and hot water demand. The question of whether it is a new build, renovation, or replacement of an existing system also plays an important role.

For an initial orientation, you can search through our categories for heat pumps, pellet boilers, wood boilers, gas condensing boilers, or electric boilers. However, the exact sizing should always be checked by a professional, as the appropriate heating output cannot be determined solely based on living space.

A buffer storage tank makes sense when heat needs to be temporarily stored and released to the heating system as needed. It is particularly common with wood heating systems, pellet boilers, heat pumps, solar thermal systems, or combined heating systems.

It can help operate the system more evenly, reduce cycling, and better connect different heat generators. Whether a buffer storage tank is necessary and what size is suitable depends on the heating system, the output, the building, and the usage behavior.

You can find suitable spare parts most easily by manufacturer, model, series, article number, spare part number, or information from the type plate. Use the shop search for this or select the appropriate manufacturer in the spare parts section.

Photos of the type plate, images of the defective component, and available documents such as the operating manual, exploded view, or spare parts list are also helpful. For safety-relevant, electrical, water-carrying, or combustion-related components, the selection and installation should be professionally checked.

For quick and targeted advice, providing as much precise information as possible is helpful. This includes the desired product type, manufacturer and model of the existing system, photos of the nameplate, technical documents, existing article or spare part numbers, as well as information about the building or heating system.

For heating systems, additional details such as living space, insulation standard, existing radiators or underfloor heating, hot water demand, chimney, available space, and desired fuel are also important. The more precise the information, the better the expert consultation can narrow down suitable products or alternatives.
