Installing a geothermal circulation pump is a very simple matter. If it is a pressure pump, install it inside the inlet valve of the water supply line. If it is a water return pump, install it indoors. At the end of your home's return water line, it is also in the inlet line valve. Generally, a domestic return water pump with a lift height of 6 is sufficient. Gears can be selected accordingly. at different pressures during installation, just pay attention to the flow direction of the pump. (It is recommended to ask professionals to install circulation pumps for domestic floor heating.) Please see the following instructions for specific operations:
Method illustration water drainage for underfloor heating
Valuation requirementsacuation of floor heating Follow the fixed sequence, otherwise there will be air resistance inside the floor heating, preventing the internal water from circulating and the floor heating will not be warm. The valve switch is closed horizontally and opened. vertically. The specific operation steps are as follows:
1. Close all valves, main valve, bypass valve, purge valve.
2. Open the main water inlet valve.
3. Open the return water discharge valve.
4. Open the first return water diversion valve.
5. Open the second bypass valve when clean, bubble-free water flows from the return water purge valve.
6. Use the same method to open the remaining bypass valves.
7. Finally, when opening the main water return valve, close the return water drain valve to complete the operation.
How to drain water from underfloor heating:
1. Prepare the water pipe and clamps, find the water collector, then close all the valves of it, find the water drain position, then find the air release port of the water pipe water inlet on the water dispenser. Touch it with your hands. Hot is the water inlet pipe and cold is the return pipe;
2. Connect the water hose to the air release valve on the water dispenser inlet hose. this time, be sure to pay attention to the water drain pipe. Always have someone looking out for you. Because the water pipe may burst. Prepare a towel and wrap it around the valve, then use pliers to open the valve. Make sure to do it gently to avoid water leaking everywhere;
3. Then put the air back into the water line. First, close the main valve of the main water return pipe. The main valvee is a long green or red handle. It will automatically close when turned 90 degrees. The method is the same as for water inlet above. Simply connect the hose to the water dispenser's air release valve;
4. Then put in a single water pipe. Operation method: First close the main return valve. . Then close the small valves of the water inlet and return pipe of the geothermal pipe one by one, and then deflate the air relief valve of the return pipe of the water dispenser until hot water sort. Start by closing the small water inlet and return valves of the first pipe, then open the small water inlet and return valves of the second geothermal pipe. Simply deflate the geothermal tubes one by one;
5. Check if deflation is successful. Mainly observe whether there is sewage and gas bursting inside. If so, he has practically atdyes a stable state;
6. Finally, open the water faucet, including the main return pipe and each pipe. Finally close the purge valve tightly. Underfloor heating and water drainage are completed.
When we empty the underfloor heating, we can only deflate the air, but not the water. It is normal for a small amount of water to flow out during ventilation, and generally. When the valve is opened, water will flow out. If you hear an empty sound, it proves that there is air in the floor heating pipe.
