Water-bearing heating fireplace

A smart heating system

Sensible water heaters with a fireplace atmosphere

This is where maximum fire experience meets hot water generation and heating with wood: a water-bearing fireplace emits gentle radiant heat into the room through its large-format viewing pane and at the same time generates hot water for the heating system.

Pioneer of water-bearing appliances
BRUNNER was one of the first manufacturers to offer its tried and tested wood stoves for craftsman's stove construction as water-bearing models. In addition to the familiar fireplace or tiled stove effect in the room where the stove is installed, part of the heat is fed into the heating system.
Safety for the customer
Partners in the trade have been familiarised with the set-up and limits of the application in many training sessions. This provides security for interested parties and customers who wish to secure their basic need for warmth in this way. 
Proven quality
All water-bearing heating inserts are tested as individual fireplaces and meet the requirements of the amended 1st BImSchV as well as the requirements of the law in Austria and Switzerland.

For primarily heat

There is probably no more beautiful and sensible way than to secure warmth for your home with a fireplace or tiled stove. To support an existing heating system or in the transitional period, it is a pleasure to heat with domestic energy. It is associated with a feeling of security and the conviction of being able to provide the basic need of warmth for one's family at any time. Coordinating which type and construction method is the right one requires detailed consultation.

Stove cover
The storaged warmth is absorbed as comfortable radiant heat by the stove cover after the combustion end.
Simply explained

How does the heat from the wood get into the radiator?

The heat release takes place in the combustion chamber. During the process of combustion, the combustion chamber walls are strongly heated and heating gas temperatures of 600 - 800 °C are reached. Depending on the application, one or both effects of heat release are used to heat heating water. If the hot combustion chamber walls are installed in a boiler shell, they heat the metallic shell of the boiler body and the heating water inside. Even more heat can be extracted from the hot heating gases. After the combustion chamber, these flow through a metallic water heat exchanger. This is the most effective method of transferring the heat from the heating gases to the water. The boiler body and water heat exchanger are designed to form a structural unit. Through both processes of heat transfer, the water heats up to 70 -80 °C, is collected in a buffer tank and heats radiators, floors and wall panel heaters as required. The installation room is heated during combustion via the firebox radiation through the viewing pane. In water-bearing wood-burning inserts, the heating gases are used directly or the residual heat after the water heat exchanger to heat a storage mass. The heat stored in this way is released through the stove casing as pleasant radiant heat at the end of the combustion process.

Water modules

How the water-bearing fireplace works

Water-bearing fireplace inserts are offered with different viewing glass and firebox sizes. The viewing pane provides a fireplace atmosphere and heats the room during combustion. The design of the boiler body and water heat exchanger determine the proportion of heating water for heating support. With a large boiler output, a "sauna effect" in the installation room is prevented during frequent heating. It is the art of the master furnace builder to select the right choice in consultation with the building owner for the respective desired application.

1st Federal Immission Control Ordinance (BImSchV)

How does the legislator assess water-bearing fireplaces and wood fire stove systems?

The amended and currently valid 1st Federal Immission Control Ordinance (BImSchV) regulates not only the emission limits of single fireplaces in Germany, but also heating with water-bearing fireplaces and wood-burning fireplaces.
The following points should be noted:

  • If a water-bearing fireplace or tiled stove is installed as the sole heating system, it is assessed as central heating and no longer as a single fireplace. This results in a repeated measurement obligation via the chimney sweep.
  • If a water-bearing fireplace or tiled stove is installed for heating support, it is classified as supplementary heating. In this case, there is neither an initial measurement nor a continuous measurement obligation via the chimney sweep. As a prerequisite for the operating licence of the water-bearing individual fireplace, proof of the type test is sufficient.
  • The nominal output of the individual fireplace must be oriented to the heat requirement of the room where it is installed.

A fireplace is the modern alternative to an open fire when it comes to heating as efficiently and appealingly as possible. A water-bearing fireplace, also called a "Kaminkessel", takes this game even further - the wood fire at home becomes the heating system. High-tech elements ensure that hot water is generated by the energy of the fireplace.

For the user, the procedure is exactly the same: you heat your fireplace and quickly get soothing warmth and a spectacular open fire. But at the same time, you feed the energy that is produced anyway into your hot water circuit and use it as efficiently as possible. Heat up once and benefit twice: Enjoy the atmosphere of the fire and save money. Especially in the transitional period, one or two fires per day are sufficient to supply the heating system with enough hot water without the need for the main heating system.

Heating systems by BRUNNER not only work for themselves, but also excellently as a team. With our unique BRUNNER BHZ heating centre, it is possible to combine all energy generators and consumers in one system. Combining a water-bearing fireplace with a wood boiler, gas boiler or oil heating, for example, is child's play - and as efficient as can be. A special constellation is a water-bearing fireplace together with a heat pump. While the latter is not very effective, especially on very cold days, a water-bearing fireplace can provide the necessary balance. As a team, this helps the in-house heat pump to compensate for periods of weakness so that it can function as effectively as possible.

The big picture is the supreme discipline these days when it comes to planning intelligent concepts for your own four walls. One control for everything and a system that combines practical elements such as log and pellet boilers with a fireplace make life so much easier. That's why we at BRUNNER focus on thinking ahead. Only in this way is it possible to find the best solutions for truly every user. When it comes to water-bearing fireplaces and tiled stoves, we are not only leaders in the market, but also drivers of innovation.

Better some euros more for the brand quality of BRUNNER
Ralf Lenz: Dear Ladies and Gentlemen, The chimney sweep just came. He wouldn’t believe that we had left our stove burning all winter. It turns out that it's better to spend a few euros more on brand quality such as a Brunner stove than to buy cheap junk. It pays off in the long run - and the environment is happy too :-) Cordia...

After we got a new gas condensing boiler in 2017, Kachelofen Schulz from Rastatt-Rauental built a water-bearing heating fireplace for us at the same time. We are still totally enthusiastic about this combination, Mr. Schulz also showed us wonderfully how to fire optimally and burn wood effectively. Now we have obtained another B...
