Indoor sauna installation requirements
What needs to be provided for comfortable and safe operation of the sauna before its installation? The main points of the general terms of reference for the preparation of the object are given below:
Presence of a flat tiled floor
The sauna is mounted directly on the existing floor of the room. Therefore, the presence of sharp slopes, steps and level drops is not desirable. For hygiene, the floor should be tiled (try not to use slippery tiles). If active use of water is planned and you need a drain hole in the floor, a slight slope to the drain hole is provided and waterproofing is done. In this case, the perimeter of the sauna should preferably remain within the horizontal level. The presence of a plinth (water chipper) made of tiles with a height of 40-80 mm is welcome. If you prefer a dry sauna, then a drain hole is not necessary.
Despite the fact that the air in the sauna is hot enough, it must be fresh and able to circulate and renew itself, because carbon dioxide is formed during the operation of the heating equipment. Air exchange is created by the influx of fresh air and exhaust exhaust. Fresh air must be able to enter the steam room. Almost always, it is possible to achieve a natural inflow from the dressing room or an adjacent room, where fresh air enters through the cracks under the doors, windows, supply vents by natural or mechanical induction. A constant flow of air, directly into the steam room, is carried out through a gap under the door (about 30-50 mm high) or through a special hole at the base of the heater. When installing the heater far from the door, it is necessary to install an additional air inlet near it. Fresh air, entering inside - passes through hot stones, heats up and circulates inside the sauna. The outflow also occurs naturally or mechanically - through the exhaust holes. It is desirable to place them diagonally on the opposite side of the furnace. It is necessary to ensure that exhaust air enters the ventilation system through ventilation ducts designed for elevated temperatures.
Possibility to connect electric heating equipment
If the sauna is provided with electrical equipment, then for its safe and uninterrupted operation, a separate electrical cable is required, which must be connected to the sauna installation site. The other end is output to the electrical panel. Wiring must be reliable, designed for continuous use and connected to earth. A low-power electric heater stove (2.5-3.5 kW) can be connected to a single-phase 220 volt network. For this, a standard copper electrical cable 3x2.5 mm is sufficient. More powerful heaters (4.5; 6.0 kW) should preferably be used in a three-phase 380 Volt network. If this is not possible, then with a single-phase connection of such a furnace, the cross section of the three-wire wiring should be increased to 4 mm. As a rule, it is allowed to connect a heater with a power of no more than 6 kW to a single-phase network, in rare cases up to 8.0 kW (minimum wire cross-section 3x6 mm.). High power heaters (from 9.0 to 30 or more kW) are connected exclusively to a three-phase 380 Volt network. If the selected heater model has a built-in control unit (usually heaters up to 9 kW), then the power cable is connected directly to the stove installation site. In the case of using remote control - to the place of installation of the console or its power unit (if a console with a separate interface is used). Make sure that the electrical load required to heat the steam room is within the capacity of the existing electrical network. In case of restrictions - expand the possibilities of electricity consumption or use a wood-burning stove.
Sufficient area and space
Make sure the dimensions of the sauna you choose are comfortable in relation to the surrounding space and do not create inconvenience. And also make sure that there are no obstacles for opening the door outward at least 90 degrees.
