PEX Tubing rates and other things

Radiant floor, usually leads to some decrease in relative humidity above the floor as the floor temperature increases. Relative humidity does not possess the "self-regulation - if any zone (room) temperature increases, the relative humidity in this zone is reduced.

A tree is relatively low thermal conductivity, for example, compared with ceramic tiles. Therefore, at the same temperature floor tile floor will feel noticeably warmer than the wood. Conversely, in the warm season tile floor will feel cool in comparison with a wooden floor, so the water floor heating under tiled flooring is included, even in summer.

Two types of wood are not suitable for systems with floor radiant heating - a beech and maple. The reason is that these sorts of wood too much change their geometric dimensions when the relative humidity. However, there is a special method of drying, in which "killed" about 60% of the cells that make these woods is largely less susceptible to the influence of relative humidity, wood "stabilized." When applying this method, both types of wood can be used with the systems of PEX Tubing heating.

All other types of wood suitable for use with heating tubing.

In view of the widespread system of PEX Tubing heating, as a rule, a manufacturer of flooring does the special character and indicates the appropriate option in the documentation (certificate): approved for use with floor heating systems.

When using wood flooring it is important to limit the temperature of coolant supplied to the system so that the temperature at the surface of the floor does not exceed 26 ° C. The best option is Weather-compensated control, in which the temperature of coolant supplied to the system varies depending on the temperature outside. The maximum coolant temperature is calculated individually for each system. Wooden floor should always be secured in normal conditions, which means the air temperature 20 ° C (± 2 ° C) and relative humidity between 30 and 60%. PEX tubing rates is not bad with compare copper pipe.

The optimum thickness of the wooden flooring is 12-15 mm. The maximum recommended thickness of 25 mm. When using the cover of a thickness exceeding 15 mm should be separate pay attention to the design temperature on the pitch, because it may be too high. In this situation, of course, the calculations must be performed by specialized in the field of underfloor heating companies.
