Is it the responsibility of the property to find someone to repair the broken water heater given by the property?

It should not be directly related to the property.

However, some warranty certificates such as warranty cards for all water heaters must be in the hotel.

The warranty service of the final product is directly completed by the water heater manufacturer after sale. It is recommended to find the property first, find the purchase certificate of the water heater, warranty service commitment and other information, in case of trouble when maintenance is needed after the warranty period.
