Damp proof layer is required: geothermal paving requirements in the ground between the pad and the ground must be coated with a layer of moisture-proof film, the moisture-proof film can prevent the evaporation of the surface of the ground after the opening of geothermal heating moisture damage the floor. There are many manufacturers in order to save a little cost to reduce installation requirements, to the geothermal floor caused great installation risks.
Installation procedures are: floor installation is not standardized, may cause a variety of quality reasons, such as: uneven ground floor will lead to floor deformation.
Floor mats to choose to be cautious: at present, some manufacturers of paper mats or aluminum foil pad as geothermal heating pad, the two floor mats in the geothermal aspects have obvious defects, leading directly to the quality of the floor damage. Paper pad in the long period of geothermal evaporation of moisture erosion, will gradually decay, loss of cushion moisture effect, make the floor damage; and the use of aluminum pad will seriously affect the thermal efficiency. Geothermal heating does not involve convection, then the geothermal system heat is to achieve heating effect by conduction and radiation in two ways, but the aluminum foil mats aluminum foil heat reflected back to the surface, resulting in heat radiation can not reach the room, not only affect the heating effect, and a waste of energy.
