Why did the fireplaces become metal?
Such fireplaces made of metal have a number of properties that make possible their use even in a city apartment. First of all, this is the light weight of the finished product. As a rule, it is an order of magnitude lower than that of fireplaces from familiar materials and traditional designs. In addition, and the overall dimensions of such fireplaces is much smaller.
The installed fireplace practically does not create additional loads on load-bearing floors, it can be very effectively located in a niche formed of gypsum board structures. It can be said that the existing models, provided that the chimneys and exhaust ventilation are properly installed, allow the firewood to be burned even in an ordinary city apartment, which sounds even more tempting.
As it is known, metal furnaces-fireplaces warm up much more quickly and efficiently give out heat. A variety of forms and forms of structural design and design solutions for such heaters are many. And this is an undoubted advantage, allowing to build a fireplace in any existing layout and appearance of housing.
Features of installation and operation of metal fireplaces
It should also be said that steel fireplaces, being a product of sufficiently high-tech production, have complex composite materials and components in their construction. Heat-resistant steels, cast irons, brass alloys, etc., serve as a material for many. As a rule, the design of combustion chambers is rather complicated.
Made of refractory ceramics with chamotte inserts, such chambers are a product of high technologies. It is not uncommon in furnaces and fireplaces to use techniques with "double combustion" using the designs of "economizers".To monitor temperature conditions and smoke, special sensors are used, connected to powerful ventilation systems. And apparently everything looks simple and very traditional.
The traditional fireplaces that have received such a high appeal, in addition to the above-mentioned large weight, which requires the erection of a special foundation, their construction in a finished house is associated with a large number of inconveniences.
As a rule, if the fireplace in the house project was not originally built, its device in the finished house is very problematic. Another thing - iron fireplaces, they can be located anywhere, allowing the equipment of the exhaust pipe. In this case, it should be borne in mind that the fireplace requires its own pipe, and it is not possible to combine exhaust ventilation from several heating devices in one pipe.
The peculiarity of the installation is that the furnace must be isolated, it is better to install the fireplace on a fire-resistant base. When extracting a fireplace or stove exhaust into a pipe, in order to avoid burning out the last one, it is necessary to install a chamotte section at the entrance to the chimney.
Basic principles of self-installation of a metal fireplace
Many owners make a metal fireplace in their own homes. In addition to the options for the complete manufacture of all elements with their own hands, this possibility is provided by modern manufacturers that produce fireplaces and stoves from metal in the form of kits based on the do-it-yourself design. In addition, it is better to build such a fireplace, using furnaces produced in industrial production.
As a rule, most of their designs are based on the convection method for heating indoor air. It is important to determine the hood, as already mentioned, for a fireplace it must be individual. In the place of accommodation, it is necessary to arrange a refractory base of chamotte, excluding the influence of heat on the floor, its covering, etc.
The same measures are taken with respect to the walls of the junction. For the drawing pipe, a special chamotte bend is used, which ensures the safe exit of high-temperature gases from the combustion of fuel. If decorative lining is provided, it is carried out using refractories, which as a rule are lightweight slabs and chamotte blocks.
