Heat about reserve

If you snap the country house with the help of a fireplace with a firebox, you can save electricity and do without expensive boiler equipment. However, the rooms are heated only until firewood burns. How stock is the warmth of the future so that at night I did not have to get up and rejected the fire?

Modern fireplaces and fireplace furnaces are efficient and economical heating equipment: they produced heat costs 2-2.5 times cheaper than heat from electric heaters.

Many aggregates are equipped with a function of long burning, and yet one wood laying is usually enough for only 3-4 h (the exception is gas-generated furnaces of large sizes). As soon as the flame goes out, the metal case begins to rapidly cool. As a result, Zyabko becomes night, and to breakfast you have to go down in warm sweaters. Let's talk about improvements, thanks to which the fireplace acquires the heat accumulating ability.

Solve the problem of heating dacha, by purchasing a firebox with a boiler, however, it will be necessary to mount the water heating system.

It will be much easier if equipped with heat accumulating elements aggregate

Stone will help

Most of the finished fireplace facing is made of light concrete, and this material almost does not accumulate heat. However, you can order a finishing kit from the natural stone of talcomagnesite or talco chlorite, which has a very high specific heat capacity - about 980 J / kg • K (about 1.6 times higher than that of the furnace brick). Such products are in the range of companies "Tehnolit", "Warm stone", "Energoress-T", etc. If you have acquired a popular furnace model, it is enough to make a prepayment - and after 3-4 weeks the masters mounted the set, the cost of which will be 90- 260 thousand rubles. Depending on the dimensions and design design. So that the heat is enough for the night, the thickness of the vertical cladding should be at least 60 mm, and the top cover is 100 mm.

Another option is to find a cook, which will fold for the furnace of the casing of the brick or chamotte blocks. In this case, between metal walls and stone masonry, it is necessary to leave a gap of about 10 mm, which compensates for the thermal expansion of the device. The working solution is prepared from chopped chamotte clay with the addition of 10% cement.

But the brick box, even with embellished seams, is unlikely to decorate the interior - it is necessary for a finish, such as a furnace cafeter. Prices for flat tiles start from 500 rubles. For 1 m2, on the boxed (sample) - from 4 thousand rubles per 1 m2. The first is fixed with heat-resistant glue ("supercohol", "terracotta", etc.). The tiles are additionally attached to the wire in the process of laying. In addition, the heat accumulating casing can be bled by natural stone (it is best - sawn talcomagnesite, but the usual sandstone is suitable) or decorative bricks.

Unfortunately, the factory oven-fireplace is unlikely to succeed with bricks. It's all about the inconvenient configuration of the body, moreover, such devices are usually installed without foundation: the overlap is likely to end the additional load. It remains to mount the heat accumulating panel with an area of 2-5 m2 close to the aggregate wall. This work is easy to perform even in a wooden house: to brushes (bars, sheathing boards) through the heat-insulating substrate (for example, Rockwool Fire Batts or Minerit LW SAUNA) fasten the drying sheet (GWL), and the furnace ceramic tile or natural stone is glued to it 30 mm.

Sewberry design is manually controlled and, unlike swivel damper, cannot be equipped with a cable drive

Close overnight

A significant part of the heat accumulated by the campaign by the corps at night will volatile through the chimney. To reduce heat loss, at the end of the furnace it is necessary to close the air intake holes. In addition, it will not hurt to equip the chimney with a gaming valve. However, the latter in no way should completely overlap the smoke channel - otherwise there is a danger to choose carbon monoxide gas. In case, smitters remained in the furnace, the emergency hole should be provided in the flap.

Reserve battery

The upper part of the fireplace is heated the strongest, so it is advisable to place special heat record plates and volumetric modules made from cast iron or chamot. They are produced for specific shaft models, but there are universal; Such products are represented by Wolfsheyer Surveque, SCHMID, Brunner, etc. Plates are mounted not only on the top, but also on the side walls of the furnace (if the corresponding mount is provided for them). However, the effect will notice only if the mass of the heat accumulator is large enough (from 80 kg), - study the passport of the furnace and make sure that it will withstand a similar load.

In addition, there are special volumetric modules from the chamot, which are fixed on the initial segment of the chimney with the help of clamps. And Romotop and "Wolfsheyer Surveque" produce combined smoke-circulation - they are installed next to the fireplace or behind it and are facing the cafeter or mask the ventilated design of GWL. The mass of such floor heat accumulators ranges from 120 to 250 kg, and they are able to maintain heat to 12 hours. However, such devices significantly worsen the thrust, and therefore, it will have to increase the height of the chimney and / or additionally insulate its upper part.

Stone facing capable of storing heat to 24 hours, but its mass usually exceeds 150 kg, and the fireplace may require the foundation

Chamotte and metal heat accumulating modules are quite accessible - from 12 thousand rubles, and the team smoke turnover will cost at least 60 thousand rubles.

A simpler and cheaper (but not so effective) solution is to assemble the first 2-3 M chimns from sandwiches, in which the space between the inner pipe and the shell (casing) is filled with pearly sand. If the furnace or furnace-fireplace is not designed for significant pressure from above, a heavy chimney is easy to drink onto the wall using a steel bracket.
