The dry type floor heating is named dry type ground heating because it does not need floor heating and backfill relative to the ordinary floor heating installation mode. Dry floor heating is a new type of floor heating method based on pipe laying in the floor heating module. The dry heating module includes a thermal conductive layer and an insulating layer, the thermal conductive layer is located above the insulating layer, the thermal conductive layer is fixed with the insulating layer, and the thermal conductive layer and the insulating layer are correspondingly provided with a geothermal coil groove.
Wet ground heating
Wet floor heating is covered with concrete laying plumbing coil leveling in the room on the ground, and then the laying of the floor, through the two-way circulation mode of low temperature hot water pipe special, the floor and concrete layer is heated to a certain temperature, then evenly to the indoor heat radiation method of heating.
"Dry ground heating" and "wet ground heating" ultimate PK
The warm wet backfill layer (i.e. leveling layer) in the concrete not only play a protective role, fixing plumbing pipes, the main channel or heat transfer, can make heat evenly, reduce the occurrence of local overheating or too cold. Warm and dry mature relatively wet and warm, often appear local overheating and undercooling, uneven heating, heating up the slow.
Dry heating requirements of floor heating module material, the general market is extruded plate with a groove, plastic material easily at higher temperature, the volatilization of harmful substances. And wet ground heating is pea concrete is relatively more environmentally friendly and healthy.
A warm wet backfill layer (i.e. leveling layer), play a buffer role, did not let the floor heating and direct contact, protection of the heating will be better. Dry to warm without backfill layer heating coil is relatively easy to damage, reduce the service life of heating to a certain extent, and even prone to Water Leakage post maintenance problems.
Wet to warm the market share as high as 90%, the technology is relatively mature, dry heating is a new heating methods emerged, the market share of 10%, and the dry heating cost will be relatively high 25%.
