What is Geothermal floor?

- Jul 02, 2019-

The geothermal floor is a floor which can be connected with the ground radiation heating system and is used for transferring heat to the room through the plate. There are a lot of floor types on the market, such as solid wood floors, laminate floor and so on. The geothermal floor has special requirements for environmental protection (no formaldehyde release hazard), good stability (moisture-proof and heat-resistant non-deformation) and good thermal conductivity.


Which floors can be used as floor heating floors?

1. Solid wood floor

It is not recommended to use solid wood floor as geothermal floor. The main reasons are: first, solid wood floor usually need the keel which is not conducive to laying. Second the moisture content of solid wood floor is relatively high, and it is easy to cause cracking and deformation after being heated. Third, because of the keel the space between the heating cable and the floor is filled with air and this is not conducive to heat transfer, affecting the effect of floor heating and causing energy waste. The solid wood floor is generally thicker than the engineered wood floor, and the heat transfer property is weak than engineered wood floor.


2. Laminate Floor

Laminate floor overcomes various defects of the solid wood floor. The surface of laminate floor is provided with a wear-resistant layer. Even the hard scraping can not cause damage to the floor, reducing the difficulty of the maintenance. The moisture-proof layer of the laminate floor can absorb the moisture in the air and the floor will not deformed due to a change in humidity or temperature. But the formaldehyde content of the laminate floor is high, and the formaldehyde is easy to volatilize after being heated. It is necessary to choose floors with good quality.


3.Engineered wood floor 

Engineered wood floor is compounded with a multi-layer plywood and the beautiful veneer of the solid wood floor. This construction ensures the smoothness and stability of the wood floor, and preserves the beauty of the solid wood floor.The thickness of the engineered wood floor is mostly between 7 and 8 mm, so that the heat generated by the geothermal system is easily conducted to the surface. The surface of the composite floor is a wear-resistant layer and the heat transfers fast and uniform on the surface of the ground. What’s more the formaldehyde content of the engineered wood floor is low.
