Fireplace stoves: Heat, please, save - Novinky.cz<

Fireplace stoves: They warm, please, save money

With them, you can heat not only a cottage or a cottage, but also a family home. You can only use them for heating in combination with another source, but they will also reliably serve as the main source of heat.

Cheap heating, luxury lifestyle

The costs invested in the fireplace stove are definitely worth it. Just compare how much a cubic meter of gas or a kilowatt of electricity costs - and how much wood, pellets or coal will cost you... You will find that the investment in purchasing a stove will pay you back in a year and a half in the difference in fuel prices.

Cheap heating, however, is not the only advantage of fireplace stoves. Glass doors give them a special charm. The sight of the flames warms not only the body, but also the soul. An ordinary radiator will never conjure up the warm comfort in the evening, when only the soft crackling of wood is heard in the stove and the reflections of the flames dance on the walls.

With or without an exchanger?

If you only need additional heating, or heating in a small cottage, a classic fireplace stove will suffice. This will heat the main room in which they will be placed, and the heat will spread further through the open door. But if you want the main source of heat for a larger apartment or house, you will definitely use a fireplace stove with a hot water exchanger.

The exchanger is connected to the heat distribution to the individual rooms via pipes and radiators and then heats the entire apartment including the water boiler without any problems. It does not have to be connected all the time. It is possible to shut it down, replace it with a plug and, if necessary, reconnect it to the system.

Tile stove: In an apartment like in a castle

Traditional tiled stoves are a return to a time-proven classic. The view of them will turn the living room into a romantic castle room or a cozy country cottage, it depends on what you prefer. Each piece of stove is an original, charming to look at and different from the others in details. In addition, stoves can have many color shades and various shapes, so you can create magic with the design of the stove as you wish.

Technical arguments also speak in favor of stoves with a larger proportion of ceramic cladding: They have high thermal efficiency and very economical operation with low fuel consumption. They perfectly accumulate heat, which is gradually released from them. A non-negligible argument is also the low maintenance requirements (it is enough to apply twice a day), practically no service, and a very long service life.

Disadvantages of tiled stoves include higher weight and longer heating time. For occasional heating at the cottage, it is therefore better to get a double-skinned sheet metal stove, for example UNI 1700, or a small cast-iron Trenk stove, which heats up immediately.

Cast iron stove: durability and technical elegance

Cast iron stoves combine the advantages of sheet and tile stoves: They heat up quickly like a double sheet fireplace stove, but they can accumulate radiant heat that radiates long after the fire goes out like a tiled stove. In addition, they are nice to look at: the material itself, dark gray, matt shiny cast iron, gives the impression that it will last forever. And it's not just an impression.

Solid gray cast iron is a technical alloy of iron with a carbon content higher than 2.14% and other elements (silicon, manganese, phosphorus and sulphur). It is characterized by high compressive strength and thermal conductivity. It is very resistant to burning, it is not damaged or changed shape by heating.

The basis is to count well

In order for the stove to work optimally, you need to calculate its performance well. The fireplace stove must be correctly loaded. If you underestimate the performance and overload them, they may crack due to overheating. If, on the other hand, you buy a stove that is too strong and add too little to avoid overheating, you will smoke the windows unnecessarily and the heating system will not work optimally.

For a basic orientation, you can start from the assumption that 1 kW heats about 30 m³ on average. However, a lot depends on the entire building - how old and insulated the house is, what the heat leaks are. Example:

You have a well-maintained house from the 1980s (well-insulated roof, plastic double Euro windows) with an area of 100 m² and a ceiling height of 3.2 m. So you heat 320 m³. Given the condition of the house, we divide this volume by 30 (average value between 20-40 m³), i.e. 320 : 30 = 10.67. The stove should therefore have an output of approximately 11 kW.

It is therefore worth having your rough estimate confirmed by a heating engineer or specialist stove dealer. He will ask you, among other things, the size of the space you want to heat (you can calculate it easily: multiply the useful area of the apartment by the height of the ceiling), the height of the chimney, or the diameter of the chimney or flue, so that you can properly connect the stove to the chimney.
