The electric heating anti-frost-crack device can normally start to work only when the water heater is in a power-on state, and the situation that the electric heating device cannot be started and a water heater pipeline is frost-cracked due to the fact that some users have the habit of pulling out a power plug of the water heater after using the water heater, or have power failure at home, or a newly-decorated house does not use power failure for a long time and the like can be caused. The water channel of the water heater is usually a normally open valve at the water inlet end and a normally closed valve at the water outlet end, so that if a user does not find that the water inlet valve is closed in time, the whole machine leaks water, and property loss and safety problems such as water soaking on the floor, electric leakage and the like are caused.
