In specialized stores today you can see a fairly large number of modern heaters, on the labels of which it is written that they serve almost forever. In fact, practice shows that this parameter is somewhat exaggerated. The service life of such products does not exceed 40 years, and in order to achieve this result, it is necessary to carefully observe the installation technology of the insulation.
Of course, if you use a heater in climatic conditions close to ideal, then a modern heater will last specified time without loss of its operational properties, however, the likelihood of such conditions for decades extremely small.
And what do experts say about such heaters as ordinary sawdust and shavings? What myths exist regarding these folk heaters and what is the reality.
- myth one, these heaters are extremely short-lived. The reality is that sawdust insulation has been serving for centuries and there are numerous confirmations of this. The best option for insulation from these materials is a mixture consisting of sawdust, shavings and lime - fluff. One part of fluff and ten parts of sawdust are taken (1:10). An important condition is that sawdust must be thoroughly dried and have a moisture content of no more than 18% at the time of laying. This recipe for insulation has been known for centuries (it used to be called "Heater");
- myth number two - such a heater is very expensive (like everything natural today). Reality - the manufacture and delivery of such a heater does not exceed 150 rubles. per cube Moreover, in regions where there are many forests, the price of the product will be much lower;
- zoological myth - in the sawdust, a lot of rodents and insects find their homes. The truth is that insects live in any insulation material as long as there is water nearby, and rodents live where there is food. No food, no rodents. By the way, they do not really like bulk materials, so sawdust should be larger, such as chips or shavings. Dry, liquid or slaked lime and glass, crushed into small crumbs, must be added to the mixture of sawdust and clay. An effective way to prevent the entry of rodents are metal mesh and metal corners;
- the fourth myth is a high fire hazard. This is not true, pressed sawdust does not burn, but smolder.
Practice shows that it is best to use dry large chips, sawdust or wood chips. For a disinfecting effect, antiseptics are added to them, for example, fluffy lime. Clay (dry) or earth (hardened) is laid on top of the sawdust. This is necessary so that the insulation is not blown out by air currents.
Such heaters can function when protected from moisture for literally centuries, the reliability of this material has been tested by many generations.
If there are difficulties with sawdust, they can be replaced with chopped rye straw. It has good resistance to decay. Dry peat, dried moss, sunflower husks and dry hay are also used.
