Water-bearing fireplace and wood fire inserts from BRUNNER make you independent: They support the existing heating system and ease the burden on your wallet. There is no nicer and more sensible way to secure heat for your home. 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 conviction that you can provide the basic need of warmth for your family at any time. Deciding which type and construction method is the right one requires detailed advice. BRUNNER's trade partners will be happy to assist you.
Water-bearing fireplace and wood fire inserts by BRUNNER are among the best that the trade can offer. A simple decision should therefore be made right at the start, based on personal taste and heating requirements: If the fireplace is to heat the installation room with pleasant radiant heat, water-bearing tiled stoves are planned in order to obtain the cosy warm tiled stove effect.
A water-bearing fireplace is always installed when large viewing glass sizes and a fireplace atmosphere are desired. Only in the second step is the choice of the heating insert made. Here, the heat requirement of the building and the size of the installation room are decision criteria for the planner. The variety of water-bearing heating inserts from BRUNNER is so large that the desired solution can almost always be found with the matching fireplace or tiled stove.
The energy standard of single-family houses with a heating requirement of approx. 4 - 7 kW makes wood fire stove system with integrated water-heat a real benefit for the heat supply of many families. In the transitional period, one or two fires per day can supply hot water and the heating system without the need for a main heating system to "kick in". Even in times of "emergency", the entire heat requirement can be generated by a water-bearing fireplace or tiled stove.
An ideal combination is, for example, the BRUNNER heat pump with a water-bearing wood stove system. If the air-water heat pump no longer works as efficiently at low minus temperatures, there is hardly anything more sensible than to relieve the load with the wood stove. Especially on frosty days, higher heating water temperatures are required for the heating circuits. This is delivered by the fireplace or tiled stove boiler.
For comfortable use of such "hybrid heating systems", we recommend BRUNNER system solutions with a buffer tank and a perfect hydraulic heating installation (e.g. BRUNNER BHZ heating centre). There is no better and clearer way to control and operate a modern heating system. And what happens in the event of a power failure? With a BRUNNER emergency power supply, all the necessary heating pumps and the control system remain in operation. It's great that we have these solutions today.
At first glance, brick tiled stoves and masonry heaters or storage heaters can hardly be distinguished from each other from the outside. The different technology is hidden inside the system. But one thing is undisputed: water-bearing fireplace and wood fire inserts by BRUNNER are among the best that are available on the market.
A tiled stove is usually made of stove tiles by a master stove fitter. There are also installations made of bricks that are plastered. The lining of a tiled stove with fireclay bricks in the combustion chamber and the fitting of flues did not appear until the 20th century. A tiled stove can absorb large amounts of heat and release it into the room over a long period of time - also because of the fireclay bricks, which store the heat that is generated. The appearance of masonry tiled stoves has changed a lot in recent years. Nowadays, they are very rarely tiled, and the typical green stove tile is hardly ever seen anymore. Simple and puristic designs with clear lines, a lot of white plastered surface in combination with rich brown tones or black and large viewing windows dominate. Large-format ceramics are often used for fire tables and benches.
A tiled stove works like a hot-air stove. Behind its casing there is a heating insert - BRUNNER is regarded as the leading manufacturer of heating inserts - and at the flue of the heating insert there is a reheating unit, so that not only the heat from the combustion chamber can be used, but also the heat from the flue gases. The installation room is heated by hot air from the stove. At the same time, part of this heat is stored in a reheating box and only released over time. This means that a tiled stove cannot heat the room as quickly as a wood stove, but it can do so for much longer, even hours after the fire has gone out.
The oldest representative of all tiled stoves is the masonry heater. All components can be handcrafted by the master stove maker or it can be designed with a prefabricated firebrick combustion chamber and storage modules. There are no limits to the imagination when it comes to design and materials. A masonry heater can be heated with three to 18 kilograms of wood. It is equipped with a ceramic mass storage across which heating gas flows. A masonry heater stores the released energy in this mass. The heating effect is achieved by heat radiation through the stove cover. This so-called radiant heat is perceived as particularly pleasant. The storage determines the amount and duration of the heating power. If a lot of storage mass is installed, the surface temperature is low. This makes it almost impossible to overheat a room. A masonry heater takes a long time to heat up, but it stays warm for a long time. It is recommended to heat it at least once a day during the entire heating season
A simple decision in itself, which is based on personal taste and heating requirements and should be made right at the start.
The choice of the heating insert is only made in the second step. Here, the heat requirement of the building and the size of the installation room are decision criteria for the planner. BRUNNER offers such a wide variety of water-bearing heating inserts that it is almost always possible to find the desired solution with the right fireplace or tiled stove.
Two essential requirements must be met for the heating connection:
The heating water yields generated during a burn-off are usually higher than what is currently required by the heating system. A buffer tank compensates for this. It collects and stores the surplus and makes the required heat available between burn-offs. Depending on demand, heating only needs to be restarted after 3 - 8 hours. The buffer tank has a volume of 500 - 1000 litres. Larger storage volumes are usually not useful, as the temperature levels mix more quickly due to the buffer tank width than with "slimmer" storage designs.
Existing or simple heating systems can be operated on the touch display of the EOS. Supplementary heating functions are integrated into the control concept of the EOS via BRUNNER expansion boards.
When the outside temperatures drop, the efficiency of the heat pump decreases. Just then it is not only fun, but also makes sense to heat with wood. The wood stove is not just a waste heat stove or fireplace. Its added value for the heating system is the integrated boiler that heats the heating water.
The wood fire - the lifetime extender
The heat pump is basically always able to generate the required temperature level. On frosty days, the pure "heat pump effect" is not completely sufficient. Additional electricity is needed. The heating concept becomes perfect when the water-bearing wood stove is ignited in these situations. This creates atmosphere, saves electricity and relieves the heat pump, which is operated with a reduced coefficient of performance (COP). It is precisely these extreme operating conditions for an air-water heat pump that lead to increased wear. In combination with a stove heating system, the service life of the heat pump can be extended by 5 - 10 years. And when do people like to heat? On cold winter days. The perfect support to compensate for the "efficiency weakness" of the heat pump on frosty days. A reasonable heating concept cannot outperform this.
Only if it is known what the demand of a building is, statements can be made about the required amount of wood. Heating load calculations according to EN 12831 are prepared by engineering and planning offices and are also offered as a service on the Internet. The heating load is calculated for extremely low outdoor temperatures (-12 °C to -16 °C) (53.6 - 60.8 degrees Fahrenheit). On normal winter days, the demand is 30 - 50 % below the design case.
A masonry fireplace or masonry tiled stove is an eye-catcher in any living space. Systems that are used as room dividers are a special visual highlight. And they are unique pieces of craftsmanship, individually made by the master stove maker. There are no limits to imagination and design, from modern to classic, everything is possible.
A masonry fireplace or a masonry tiled stove are fireplaces surrounded by mineral materials such as natural stones. They are individually planned and set by the master stove fitter. In order to take advantage of the structural conditions and to ensure the optimal function of the fireplace system, the chimney sweep should be involved in the project from the beginning. He knows the key data such as floor area, flue diameter, smoke volume, chimney, height and heat output.
With masonry systems, a distinction is mainly made between two types of stove: the tiled stove and the masonry heater or storage heater. Both are traditionally built by a master furnace builder. The fireclay tiles used for this purpose store heat and give it off to the living room for a long time.
The heating insert used - for example from BRUNNER - guarantees efficient combustion, maximum heating conformity and cosy warmth. It can also be selected as a water-bearing version. In this case, the heat generated during combustion is also used for hot water preparation. The hot water can then be fed into both the heating circuit and the domestic hot water circuit. A masonry tiled stove or masonry heater, water-bearing heating inserts and solar thermal systems are also available as a combo.
There is no simpler and cheaper way to install a water-bearing wood-burning stove in the living area. As a support for an existing heating system or in the transitional period, it is a pleasure to heat not only the installation room but also other rooms with domestic energy. Perfectly implemented with the heating concepts from BRUNNER. Mature system solution that also allows complex heating technologies with several heat generators.
A wood fire stove system is only as good as the fuel and the operation. Therefore, it is important and sensible to install an electronic stove control (EOS), especially for a water-bearing stove. In addition to the effect of the automatic combustion control with the highest degree of efficiency, you get great ease of use. Just place the wood on the stove and light it; everything else is regulated by the combustion control system itself. The current situation of buffer tank load status and heating is displayed particularly clearly. Via the touch display integrated into a glass panel, everyone can follow and experience how heat is generated, stored and retrieved.
The myBRUNNER app also rounds off the range, allowing the heating to be controlled from the comfort of the sofa.
For the safe operation of a water-bearing fireplace, sufficient negative pressure in the pressure must always be available. The negative pressure safety control (USA) checks from the moment of heating up whether sufficient negative pressure is built up by the chimney to safely discharge the heating gases. If a kitchen extractor hood or a defective ventilation system works against the chimney impact, the USA switches off the corresponding fault factor for safety reasons. Otherwise, gases from the stove system could flow into the room. The monitoring unit is activated as soon as you light the wood fire. In the meantime, the system is on "standby".
