In terms of construction, floor heating should be installed on the upper part of the floor adjacent to the unheated room and on the perimeter of the outer wall of the radiant floor. Styrofoam sheet is used for the heat insulation layer, and the thickness should meet the following requirements: The insulation layer is 20mm, and the filling layer above the geothermal pipe should be covered with fine stone concrete. The filling layer on the heating pipe should be laid with 2mm diameter steel mesh.
After the construction is completed, the owner is better to check the use of geothermal heat, first of all the hydrostatic test. The specific steps include the following steps: the first step is to slowly inject the water through the water separator and discharge the air in the pipeline; the second step, after the water is filled, is to perform the watertight inspection; the third step is to use a manual pump to slowly raise the pressure; After boosting to the specified test force, stop pressure, regulate 1h, observe whether there is water leakage phenomenon; Step 5, after the pressure is stabilized for 1h, make up to the specified test pressure value, the pressure drop within 15min does not exceed 0.05Mpa without leakage qualified.
The initial heating should be heated slowly during commissioning. The water temperature should be controlled within 25°C-30°C for about 20 hours, and within 24 hours, the water temperature can reach the normal range.
