What should I do if the wall-hung boiler freezes?

1. Use a hair dryer to melt the frozen parts and pipes until the pipes and parts are not frozen.

2. For the frozen pipeline of the floor heating wall-hung boiler, the electric tracing belt with higher safety level can be selected for thawing.

3. Turn the heating temperature of the wall-hung boiler to the lowest and try to start it. You can try it many times.

4. In daily use, if you don't use the wall-hung boiler for a long time, directly drain the water in the heating system and turn it off.

5. Start the anti-freezing protection function of wall-hung boiler. The wall-hung boiler has its own secondary anti-freezing protection function, which only protects the wall-hung boiler itself and does not protect the heating system (unless the heating mode is turned on).

Extended data:

Failure and harm of wall-hung boiler after freezing;

1. The interface between plate heat exchanger and waterway valve body is frozen and cracked.

Plate changing is in a relatively low position in the whole wall-hung boiler, and it also has a certain water capacity. Take a commonly used 12 layer board switch as an example, its water storage capacity is about 300ml.

When the water in the plate heat exchanger freezes, the plate heat exchanger will expand, and the sealing surface matched with the waterway valve body will also bulge and deform, which will lead to the loosening of the fixing bolts and the leakage of water in the gap.

2. The water pump is frozen and cracked.

Because the water in the cavity of the pump seat is the largest, the common frozen crack part of the pump seat is the pump seat. No matter plastic or metal, under the great expansion force of water condensing into ice, they are not spared.

In severe cases, the shielding sleeve inside the motor may burst. If it is not replaced in time, it will leak, which may lead to serious personal safety accidents with very serious consequences.
