The drainage of the floor heating must be carried out in a fixed order, otherwise there will be air resistance inside the floor heating, preventing the internal water from circulating and underfloor heating will not be hot. The switch is closed horizontally and opened vertically. The specific operation steps are as follows:
1. Close all valves, including the main valve, bypass valve, and air relief 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 valveor to complete the operation.
The electricity consumption of electric underfloor heating per day is approximately 64 kilowatt hours.
For example:
The amount of electricity used daily by electric underfloor heating is linked to the interior paving surface, for example: a set of two bedrooms and a living room For a house of 93 m², if the housing availability rate is calculated at 80%, the actual interior surface area will be 74.4 m², then we deduct approximately 8.4 m² of balcony and kitchen without floors. Therefore, the actual interior area for electric underfloor heating is approximately 66 square meters.
Generally, the electric floor heating installed in the bathroom is 150 watts/square meter, and the electric floor heating installed in other spaces is 120 watts/square meter. The total power is approximately 8 kilowatts.
Although electric heatingground works 24 hours a day, the actual power consumption per day is about 6-9 hours. If calculated based on 8 hours of electricity consumption per day, electric floor heating consumes approximately 64 degrees. of electricity per day.
Detailed information
Disadvantages:
1 The price of installing electric underfloor heating is relatively. pupil. There is a slight radiation. Radiation from electric floor heating has minimal impact on the human body unless inferior cables are used.
2. Electricity bills are generally billed on an installment basis. If electric floor heating is used on a large area, the subsequent use cost of electric floor heating will be relatively high in terms of electricity prices. And if there are faulty areas in the electric floor heating, then allt needs to be replaced.
3. The installation of electric cables for underfloor heating requires a relatively long time and more qualified technology, otherwise it may cause problems in the subsequent use of underfloor heating. In addition, electric floor heating is also a hidden floor heating project. Once a fault occurs, the maintenance work is relatively complicated and time-consuming, requiring multiple aspects of maintenance, causing more problems.
