Residential electric boilers operate continuously and are drained once daily. Drainage method: Open the drain valve to release the wastewater inside the boiler, then close the valve.

Home electric boiler should be descaled every six months. Due to the varying water hardness in different regions, it is important to descale promptly when the boiler's heating efficiency decreases to prevent damage to the heating rod.

To ensure the long-term normal operation of residential electric boilers, it is necessary to regularly inspect the heating rods. It is recommended to check them every one to two months after the boiler has been in operation for a period of time, and to examine the scaling conditions of the water chamber and heating rods.

When a residential electric boiler is shut down, the valve should be closed and the main power switch turned off.

Residential electric boiler circulating water must undergo strict treatment, which is crucial for extending the boiler's lifespan and ensuring operational safety. The quality of water softening treatment should comply with GB1576, the "Standard for Water Quality of Low-pressure Boilers."

2. Water Chamber Inspection:

If you find scale buildup on the heating rod through manhole inspections, please consult a professional boiler descaling service or contact the manufacturer immediately. Arrange for boiler descaling promptly to prevent scale formation that may affect the lifespan of the heating rod.

3. Operation and maintenance should be conducted according to the instructions for the automatic control.

4. Boiler shutdown maintenance and care:

Home electric boilers should have the outlet valve closed and the pump stopped when they are shut down. Maintenance is necessary to prevent internal corrosion.

Short-term maintenance can be carried out using the wet maintenance method, which involves filling the boiler with water after shutting down and completely expelling the air.

When preparing a domestic electric boiler for a long-term shutdown, first conduct a boiler inspection, including checks on the heating pipes and water chamber. If necessary, perform descaling treatment simultaneously. After shutdown, maintain the boiler using a water filling maintenance method: drain the boiler water, refill with fresh water, add ammonia, at a concentration of 200ppm, close the valves, and ensure the removal of stored water containing ammonia before restarting the boiler.
