In recent years, geothermal heating has been widely used in the north, which not only ensures the room temperature in cold winter, but also has the functions of saving space, cleaning and environmental protection. It is very important to use the floor radiant heating of water system correctly, which is the best choice for green, environmental protection, energy saving, health care and residential heating. So design is the foundation, construction is the key, pipeline is the premise, and correct operation and maintenance is the guarantee. So what problems should be paid attention to in the operation of geothermal heating?

Look at three pictures first:

Save room area:

Reducing the space area of heating by conventional heating method can save 6- 10% of the valuable real room area, that is to say, a room with 100 square meters will lose 6- 10 square meters of room area for nothing because of placing and decorating radiators. If it costs 3000 yuan/square meter, it will lose 18000-30000.

Save energy:

The temperature distribution in the hall along the height direction is relatively uniform, and the temperature gradient is small, which reduces the invalid heat loss. Practice has proved that the design temperature of radiant heating room can be 2-3℃ lower than that of radiator, but the same comfort can be obtained, thus reducing heat supply and saving energy. At the same time, due to low temperature transmission, the heat loss is small.

Radiant heating and cooling is used for radiant heating and cooling.

Raise or lower the temperature of one or more surfaces of the inner surface of the envelope to form a hot or cold radiation surface, and provide indoor heating and cooling through radiation and convection heat transfer of the radiation surface.

Nowadays, the most common ones are circulating system and electric floor heating.

The liquid circulation system dissipates heat through the radiating pipes laid underground. The water flowing in the radiator pipe is driven by heat source devices (hot water boiler, heat pump), etc., to complete the heat source-radiator pipe-heat source cycle. The water with reduced temperature returns to the heat source device and is heated to the set temperature, which is a closed cycle.

Electric floor heating is generally through laying a heating cable underground, passing through the reflective film below the cable, and dissipating heat upwards. The heating cable itself is a heat source device.
