When buying, experts advise you to consider several important moments.

How to choose a heater for a bath

  1. The environmental friendliness of insulation comes to the fore today. It must not release harmful compounds under the influence of moisture, nor under the influence of heat. Considered the most harmless heat insulators based on natural materials.
  2. Since there is an open fire in a traditional Russian bath, then to finish the stove and the room in which it is placed, it is necessary use fireproof heat insulators.
  3. It is necessary to choose a heater taking into account its longevity. It should not crumble or delaminate when sudden changes in temperature or contact with water.
  4. In the bath there is a high level of humidity. Considering high temperature, preference should be given to insulation, resistant to cold water and superheated steam.
  5. For each stage of the construction of the bath, you should choose the most optimal material. For example, fill the voids between logs log house is best with the help of interventional insulation. And for floor or attic insulation is expanded clay or mineral cotton wool.
  6. Post-finish options should also be considered. baths. If it is planned to apply plaster and paint outside, then A popular polystyrene will do. And under a wooden lining it is more convenient mount a thin foil insulation.
  7. There are many suitable bath houses on the market. heat insulators, which differ significantly in price. But in pursuit for momentary benefits, it is important not to forget about the subsequent costs of installation and maintenance. For example, mineral wool retain heat-insulating properties only with a competent device steam and waterproofing. And this will require additional financial attachments.
