General questions and terms

  • What is the comfort setting?
  • What is the reduced setting?
  • What is a heating curve?
  • Why do I have to protect my BRÖTJE heating system from limestone build-up?
  • Where can I find up-to-date product documentation?

The comfort setting describes the desired temperature for your living space either while you are in it or at other specified times. You can set this value according to your preferences in the control unit of your BRÖTJE heat generator.

If there are times at which no desired room temperature is set, the heating system usually turns down to the so-called reduced setting.

The reduced setting describes the desired low temperature for your living space either while you are away or at other specified times. You can set this value according to your preferences in the control unit of your BRÖTJE heat generator.

The heating curve represents the relationship between the flow temperature (which is the temperature of the heating surfaces) and the current outdoor temperature.

To keep a building heated at a continuous temperature when the temperature outside is changing, the flow temperature has to be increased and decreased.

If the outside temperature drops, for instance, the flow temperature increases so as to heat the heating surfaces in the building more strongly.

If the outside temperature rises, the flow temperature drops and the heating surfaces are heated less.

A specialist engineer will set the heating curve for you according to the conditions in your local area. They do so using your BRÖTJE heater’s control unit. The curve then changes the flow temperature level by means of an outdoor temperature sensor and its settings.

The heating curve is skewed slightly, as the heat output from the heating surfaces is not linear at different temperatures.

With the right setting, however, the heating curve minimises heat loss, improves room temperature control, and in doing so, saves energy.

Your heating system is generally filled with water taken from the drinking water network. Quality is strictly controlled and subject to Germany’s Drinking Water Ordinance. Water in Germany is very well-suited to everyday use in the home and there is absolutely no danger in drinking it. However, drinking water does contain some minerals and hardeners that lead to the formulation and accumulation of stones when heated. You have probably seen this before in your kettle or coffee machine, both of which have to be cleaned from time to time with the likes of citric acid.

This process also takes place in your heating system and can cause damage to the boiler in particular. The deposits lead to a reduced transmission of heat and may cause material stresses which, in the worst case scenario, can lead to the heat exchanger in the boiler failing. Tiny particles from these deposits can also come off and clog the valves and filters in your system.

All this, however, can be prevented if the water is treated before being filled into your heating system. This treatment involves removing some of the hardness from the water and adding a hardness stabiliser to work as an inhibitor. This also contains anti-corrosion protection which protects your system against damage in the long run.

BRÖTJE offers water treatment equipment developed specially for heating, which your specialist engineer will be well experienced with. For more information, click here.

Current product documentation, such as brochures, leaflets and data sheets, can be found under Products within their respective section.

Service & customer support

  • Why is it important to get your heating system serviced regularly?
  • Where can I find replacement parts for my BRÖTJE device?
  • I lost my manual. Where can I get a new one?
  • The flue gas inspector discovered a fault with my BRÖTJE heating system. What should I do?
  • Something is wrong with the water pressure in my BRÖTJE heating system. What should I do?
  • My BRÖTJE device is showing an error. What should I do?
  • How can I save more energy with BRÖTJE heating system?

After a certain period of time, all heating systems require inspection – and maybe even maintenance – to make sure that everything is working safely, reliably and as efficiently as possible.

If you compare it with your car, it soon becomes clear why regular maintenance is so important:

The annual operating hours of your heating system can reach a mileage of over 100,000 km.

At least your BRÖTJE heating system doesn’t require as much maintenance as a car!

Inspections and maintenance work may only be carried out by specially trained personnel. Improper installation of or work on heating systems may result in damage to property and/or injury to persons.

If you experience a problem with your BRÖTJE device, contact your specialist engineer.

Spare parts are not sold directly to end users by BRÖTJE, as the installation of such parts must be carried out by a specialist.

Please contact your local specialist engineer.

We will happily send you your required documents as a PDF file via email or, if desired, we can also send you a paper copy by post.

Please contact us using our contact form.

Your flue gas inspector will either have given or sent you a log of his checks and the values measured.

This log usually contains a grace period in which the fault should be corrected.

In this period, you must have the fault in your BRÖTJE heating system inspected by a specialist and rectified.

After doing so, the flue gas inspector will carry out another check of your system.

On the pressure display of your BRÖTJE heater, you should see a black pointer and a red mark.

The filling pressure should be between 1.5 and 1.8 bar, although this depends on the local conditions.

The methods used to fill heating systems differ greatly from system to system. The improper filling of a system may result in significant damage to your heating system or the building. It is imperative that a specialist engineer assist you.

Check your operating manual to see whether your device has a reset button and where it is located.

Usually, the reset button on a BRÖTJE heat generator is marked by the following symbol:

If the fault cannot be rectified by pressing the reset button, please inform your local specialist engineer.

If they require further assistance with a diagnosis or repair, they will contact customer support.

As an end user, you cannot directly contact our customer service technicians.

Warranty claims must be asserted with your specialist engineer, as statutory rights to warranty claims exist only with the seller.

To find the right engineer for your BRÖTJE device, use our installer search tool.

Ask your specialist engineer to adapt your BRÖTJE device to your local conditions and personal requirements.

You should also get your BRÖTJE heating system inspected and maintained by a specialist on a regular basis.

As such, BRÖTJE recommends that you enter into a maintenance contract with a suitable specialist company.

You can find your device's recommended control settings in the operating manual.
