The gas furnace for bath

The gas furnace for bath

Choosing the furnace for bath, many stop on gas option, and for this purpose there are several reasons. The device of the gas equipment such is that just to service it. It takes not enough place, and it is important for rooms with deficit of the area. And the most important – the cost of natural gas which still is rather low.

The furnace has to keep heat, that is why throughout centuries in baths built stone constructions with pig-iron boiler for water heating. For independent construction it is better to choose easier option – the brick device. If to sort all subtleties of construction of the gas furnace, it is possible to try to create it the hands, previously having got special permission.

Choice of the place and preparation of materials

The room of bath is, as a rule, broken into several sectors. Traditional division looks so:

  • steam room;
  • washing;
  • locker room (or restroom).

Certainly, the furnace is installed in the pair room which always was the hottest. That with its help to warm and other rooms, construction should be placed about wall. Its design is simple and reminds the house heating device.

Parts of gas construction which are consistently built by the hands:

  • the basis established on the base;
  • the isolated flue;
  • torch;
  • metal substrate;
  • guidance system.

Reliability and high functional performance of the furnace are defined by characteristics of materials of which it is constructed. We will need red brick, piece of tin (galvanized, stronger and protected), steel sheet, clay, sand, metal rod, grid iron, ready purchased doors. Besides, it is necessary to prepare pipes: asbestos-cement, metal and for the gas pipeline device.

Construction of the base

The principles of construction of the base are familiar to each owner who built the hands the country house. First of all the small hole not less than 0.7 m in depth as its bottom has to be located lower than the level of freezing of soil escapes. It is necessary to provide such phenomenon as motions of layers of earth and to make the lower part of the basis slightly more widely.

The pillows device under the base is carried out according to the scheme:

  • 1 layer (15 cm) – coarse-grained sand;
  • 2 layer (20 cm) – pieces of brick, stones;
  • 3 layer (15 cm) – crushed stone.

Further from several old boards the timbering is mounted and for bigger durability the reinforced framework is created. Concrete is filled in, and about two weeks on its hardening are required. After that the timbering is dismantled, and in several layers apply insulating material on the surface of the base – tar. The cavities formed after dismantling of timbering need to be filled up with sand-gravel mix.

Construction of oven walls

Construction of the furnace should be begun with wall which plays role of protective barrier from fire. Material for laying – cut brick and cement slurry. Fans of natural materials instead of cement use mix of clay and sand – on model of ancient construction.

It is simple to prepare clay and sand solution. Clay can be found on the river bank, in career, but any will not approach: that which lies at depth from half a meter below is good. For solution certain amount of clay needs to be mixed with water, and to sift sand, then to connect both components at the rate of 1:1. The ready-made product has to be dense, homogeneous, without alien inclusions and lumps. The furnace is built in stages therefore it is better to prepare solution just before work in small amount.

Before laying it is necessary to prepare the basis. The first row of brick is put on waterproofing course for which bituminous materials perfectly are suitable. That the laying was dense, all elements accurately have on solution layer, slightly press and hold some time.

Attention! Everyone without exception the brick is laid at first in capacity with water, maintained several minutes, and then used.

Dense fitting has to be traced also in the horizontal direction, at the same time the optimum width of seams between elements – no more than 0.5 cm. Bricks should be stacked traditional laying: the upper element covers joint of two next elements of the lower row. The most pretentious handymen arrive as follows: spread walls without putting the linking solution to see how will look bake in general. The full picture can prompt that it should be changed or added.

There are special developments of gas furnaces with drawings to which it is necessary to adhere in the course of construction. To them there is breakdown by ranks and it is specified at what moment it is necessary to mount this or that part of the furnace. For example, at the device with 3 on 6 row mount the lowermost door for ashpit. It is fixed by means of strong galvanized steel elements – wire or strips. In the 4th row it is necessary to arrange niche for grid-iron and ashes. The grid-iron, as well as fire chamber door, are placed at the level of 7 row.

Attention! On sale there are fire chamber doors from different material, for example, from steel, but pig-iron products, strong and capable to long keep heat traditionally are considered as the best.

The flue begins with the 8th row, exactly here it is necessary to plan the partition device. At the level of 14 row it is necessary to fix channels. On them mount the reservoir for hot water. Access to the reservoir provides the aperture which is specially provided in laying. Four following rows are carried out from halves of the bricks located not horizontally, and under certain corner is future basis for dividing wall.

Door through which is exhausted, is in the 19th row. It is mounted by similarly lower. The 23rd row – chimney installation site.

Attention! According to standards the pipe has to tower over roof slope on 0.5 meters and more.

The more volumes of gas boiler, the more powerfully and more widely in the diameter pipe. The minimum pipe diameter, as well as flue section, is equal to half of one brick. At the flue device the sand-clay mortar is replaced cement: it will not collapse during rain.
Finishing work

Final stage is plastering of surface of the furnace. It has two main objectives: ensuring additional protection against ignition and creation of esthetically attractive look. There is set of types of solution for plaster, many of them contain alabaster. It has one advantage before plaster – not so quickly grabs.

The most plain solution is prepared as follows: take clay, sand and alabaster (plaster) and all carefully mix. Before drawing plaster layer from the surface of the furnace delete excesses of solution and make putty.

Choice of gas boiler

Gas boilers usually use for heating of private cottages, but relatively special devices for baths and saunas have appeared recently. They successfully function on natural main, and in certain cases – on liquefied gas. Profitability, lack of smell and soot – it is unconditional, their positive sides.

Attention! Cylinders in which liquefied gas is stored need to be established outside the room, optimal variant – to earth.

The normal solid fuel stove concedes to the gas equipment in several parameters. So, than gas boilers are good?

  • Need for preparation of firewood for the furnace vanishes, therefore, it is not necessary to build special canopy for storage of firewood. One more plus – lack of wood garbage.
  • The term of operation of boilers is high therefore there is confidence in durability of the gas equipment.
  • Adjustment of such parameters as air temperature and humidity, allow to create comfortable microclimate in sweating room whereas the normal furnace has no possibility of control over these indicators.
  • The gas option heats up much quicker, respectively, heats also indoor air quicker.
  • The small consumption of gas provides significant economy of means.
  • The automatic system of boiler makes blocking in emergencies.

Many owners of dachas try to create gas boiler independently, forgetting that this device of the increased danger. Only the specialist with profile education can understand all subtleties of the equipment. Full safety is guaranteed by only the precast gas system – at observance of service regulations.
