Installation of metal furnaces: requirements and methods

For many people, the stove symbolizes comfort. Fire creates an environment that promotes relaxation for the soul. Recently, metal aggregates are in the greatest demand. And the reason for this is both reliability and high technical characteristics. Like any heating device, a metal stove is mounted in accordance with fire safety standards and regulations. The requirements for installation in wooden houses are undoubtedly more stringent. Proper installation will not only avoid accidents, but will also help to maximize the efficiency of the unit. The article will discuss how to install a metal stove.


Modern heating metal stove

This equipment is widely used for heating baths, summer cottages, working trailers and other small areas..

Over the years of “evolution” it has undergone many changes, which had a positive effect on the following parameters and nuances:

  • functionality. Today manufacturers offer models that operate in different temperature conditions. Such parameters allow you to choose the optimal microclimate;
  • Efficiency. The advanced design allows the choice or combination of different fuel choices, achieving efficient space heating. Due to the increased area of ​​the furnace, the fuel is completely burned, which in turn increases the efficiency;
  • equipment. The equipment can be supplemented with a water heating tank, which is important not only for baths, but also for residential buildings in summer cottages or garden plots;
  • design. The lineup allows you to choose a product in a stylish design. Ergonomic shapes with high efficiency – the perfect combination. Metal devices are decorated with decorative elements made of glass or forged parts.

Fuel type for metal furnace

This versatile heating source can be operated with a variety of fuels:

  • electrical models equipped with a whole range of functions designed to increase the comfort of use (remote control, panel for setting tasks, etc.). Heating elements quickly provide the required temperature. However, with a power outage, you will not be able to enjoy the warmth. It is recommended to install a generator to solve the problem. The cost of such furnaces is 12-15 thousand rubles;
  • gas equipment thanks to the burner and thermostat, they allow you to adjust the intensity of combustion. It has a reliable security system: automatic sensors and controllers that are triggered in case of force majeure. The units are quite economical, but in the absence of natural gas, it will be necessary to purchase liquefied propane-butane. The price varies between 15-17 thousand rubles;

  • wood stoves are the most popular. This factor is due to simple maintenance and repair, as well as the available fuel. There are models on the market that imitate a fireplace. The equipment heats up the room rather quickly. Chimneys work to completely remove combustion products. The cost of such heat generators starts from 12 thousand rubles;

  • furnaces fueled by fuel oil, diesel fuel and a special distilled composition, are characterized by a high degree of safety. In addition, such devices are economical in view of the raw materials used. Some models are equipped with a toggle switch for switching from one type of fuel to another. The simplest units will cost only 2,000 rubles.

Choosing a metal stove for your home

A metal oven should be selected based on indicators such as:

  • heating rate of a certain area;
  • the maximum and minimum temperature that the equipment can support;
  • the size of the firebox and the unit itself;
  • metal alloy used for manufacturing;
  • door modification;
  • ease of use and maintenance.

Mainly on the market there are equipment made of cast iron, black and stainless steel. In terms of dimensions, it is divided into:

  • mini-ovens with space heating up to 12 sq.m .;
  • standard ovens for maintaining the temperature of 12-24 sq.m .;
  • large ovens capable of heating air in areas over 24 m2.

For cladding, ceramics and talcochlorite are used in their various modifications. Such materials increase the initial heating of the heating equipment, but significantly reduce the unpleasant burning heat and increase the heat release time..

In some models, stone cladding plays only an aesthetic role, without affecting the physical and technical characteristics of devices. Decorative panels are removable, so that it will be easy to dismantle them and install products with a new design, radically changing the interior of the room.

Place for installing a metal oven with your own hands

  • The technical characteristics of the heating unit are of great importance, but its location is no less important. After all, heat transfer is carried out not only by convective air masses, but also by radiation emanating from the walls of the device..
  • If a brick oven gives out weak heat and its walls do not warm up over 90 degrees in normal mode, then the metal product emits a rather hard radiation and the walls of the structure heats up to 500-600 degrees.
  • The place for the installation is determined both during the design of the premises and after the construction of a house, a bath. The main criterion is the location of the window and door openings. Only in this case it is possible to predict in which direction the cold air currents will move..
  • Before installation, plan the working space for the fuel. The type of fuel does not matter, it is important to pre-calculate the delivery path and its storage near the heating unit.

Fire safety

Knowing and observing fire safety measures, it will be possible to install the stove in rooms built from any materials, including wood. Although both brick and block buildings are subject to fire hazards. Therefore, strictly follow all the requirements..

  • The unit is installed on a floor lined with non-combustible materials. This can be an ordinary concrete screed, metal sheet, ceramic tiles, etc. The edges of the surface should protrude at least 50-70 cm from the device body.
  • The walls adjacent to the stove and adjacent furniture are insulated with a heat-resistant material, for example, asbestos sheets or superisol, thus it is possible to reduce the required distance (1 m) from the wall to the rear wall of the cabinet to 20 cm.
  • There should be at least half a meter between the equipment and wooden surfaces (walls or the same furniture), optimally 60-70 cm.
  • Much attention is paid to the arrangement of the chimney system. Use additional protective elements that prevent pipe clogging and do not allow birds to build nests, which is especially important for vertically located channels.

  • The distance between the ceiling and the upper part of the casing of the heating unit must be at least 1.2 m, and from the firebox door to the opposite wall – 1.3 m.
  • To avoid accidents, especially if there are children in the family, the equipment is fenced with a decorative “fence”.
  • Some models provide for installation of ducts in the walls to heat adjacent rooms. In such cases, heat resistant finishing materials should be used. Recommendations are detailed in the instructions supplied with each unit..

Preparing the floor and walls before installing a metal stove in the house

  • Walls protected with insulating materials do not look attractive. Therefore, they are most often decorated with ceramic tiles, and floor slabs from the same collection will help to support the “corner of comfort”.
  • Ceramics are laid on the concrete floor immediately, and if it is a wooden base, then first a glass-magnesite, plywood or plasterboard sheet is laid. The material is screwed directly onto the floorboards with self-tapping screws. The surface is treated with soil and left for a day until completely dry.
  • Tile adhesive is applied with a notched trowel, this tool will allow you to achieve the same layer thickness. The first row is laid as evenly as possible, here a level is used to level the surface both horizontally and vertically. The quality of the entire surface depends on how flawlessly the row is laid out..

  • Ceramic products are mounted without or with seams. The latter option will help to hide layout errors, respectively, decreasing or increasing the distance between them..
  • After 2 days, the construction crosses are removed, and the joints are filled with a grout mixture. Decorative sills or corners are used to move from tiles to the main flooring material..
  • In the same way, the installation of tiles on the walls is carried out. Heat-resistant mastic is applied to the ceramic with five points. The bottom row does not have to be adjusted horizontally if the floor tiles were installed according to all the rules.
  • It is better to trim products to size using a stencil made of thick cardboard. The edges of the masonry are edged with a special profile that matches the sill or skirting board.

Installing a metal stove in a wooden house

Depending on the model, one or another type of connection, assembly of elements will be required. Each manufacturer tries to present equipment with a minimum set of parts. All installation information with detailed diagrams is included with the heating unit..

  • In most cases, the equipment only needs to be mounted in a prepared place. The complexity of the installation lies in the correct connection and correctly located outlet of the flue duct.

  • The chimney can run horizontally or vertically. Due to the large set of pipe elements, it can exit at different angles. It should be noted that the exit through the wall is gaining popularity, but this channel direction is not suitable for all stoves..
  • For compact models, double-walled stainless steel pipes with basalt wool insulation are used. These products are characterized by less condensation and less soot settling..
  • The preparation of the holes for the pipe is carried out immediately before its installation. To do this, collect the chimney and calculate the point of its exit. The hole diameter should be in accordance with the manufacturer’s recommendations.
  • If there is a ready-made chimney, then the pipe is passed through the shaft. If the diameters do not match, special adapters (glasses) are used. You should not use complex options for channel direction. Numerous turns will serve as points of accumulation of fuel residues.

  • The chimney begins to be assembled indoors. A pipe is fixed to the outlet of the body, which can be located on top of the body or on its back. A gate is installed higher, serving to regulate traction.
  • If the channel runs at a slope, then a half-bend with the required degree is used. Heat-resistant materials are used to seal the joints. If necessary, the so-called “glass” is mounted, which connects pipes of different sections.
  • A metal plate is mounted at the entry point of the chimney in the wall or ceiling. A technical hole is cut in it equal to the diameter of the channel. This element can be made in the form of a square flange. The height of the sides must correspond to the thickness of the floor or wall.

  • The resulting “box” is attached to the surface, a chimney is passed through the hole (from the street to the room). The empty space between the flange walls and the double-walled pipe is filled with basalt wool. The double-walled channel is connected to the adapter (glass) with the help of clamping clamps.
  • When the chimney exits the wall from the street side, a tee is installed on the pipe, from which a vertical channel will go. Its reliable fastening will be provided by wall brackets. To protect against the ingress of leaves, dry branches, the head is equipped with a deflector. This element will not allow birds to nest at the end of the pipe..

Brickwork for metal oven

A metal stove, with all its advantages, emits radiation that is too harsh, which does not allow breathing freely in its immediate vicinity. The solution to this problem is to cover the equipment with solid brick masonry..

  • Before work, you need to make sure that the floor can withstand an impressive weight, sometimes reaching half a ton. When marking, a gap between the unit body and the future wall of 3-8 cm is observed.
  • A metal sheet 2-4 mm thick is laid on wooden floors, which in turn is covered with asbestos. The width of the lining is taken with the calculation of the thickness of the bricks themselves. If the base is made of concrete or ceramic slabs, then there is no need for preparation.
  • The walls rise in half a brick. The solution is kneaded on the basis of clay mixed with sand, its density should be of medium density. The work is carried out according to all the canon of ordinary brickwork, that is, in compliance with leveling along the planes and bandaging the seams.

  • In the second row, on all 3 walls, technological holes are made, about half a brick for high-quality air exchange. They also leave holes for the blower, door and other structural elements of the furnace..
  • When the height of the wall reaches the top of the firebox door, the corners of their metal are exposed on the brick blocks, which will distribute the load given by the subsequent rows. To decorate the top, different options are used, for example: they are left open or performed in an arched form.

The cost of work in specialized firms

  • If for some reason you decide to shift all of the above actions onto the shoulders of professionals, then the installation of equipment will cost 7-10 thousand rubles. Installation work in wooden houses will be slightly more expensive. This is due to the additional arrangement of insulation.
  • The price of laying the chimney through the floors and the roof will be from 25 to 40 thousand rubles. depending on the complexity of the work being carried out. If the chimney runs along the outer wall, then you will have to pay about 5-10 thousand rubles for the installation, where the final cost will be determined by the length of the pipe.
  • It is, of course, only the owner who can decide to save on work and to install the heating unit by one’s own efforts or to seek help from specialized organizations. The main thing is that the installation of the furnace itself and the chimney system is carried out in accordance with fire safety standards..

Compliance with the rules will help to avoid dire consequences, we are talking not only about the possible loss of real estate, but also the health and lives of relatives and friends..
