I saw this method of installing a water heater in a rented apartment while on vacation in the south of the country. Usually we painfully hang large boilers from the ceiling, but here he was standing on the floor on a special stand. Many people will think about the top water supply, and they will be right, but not completely. This installation on the floor is possible for water heaters with a small volume. I installed a small spare water heater under the sink myself, placing it in the bottom of the cabinet.
Before leaving, I asked the owner of the apartment why this installation method was preferable. Firstly, given that the service life of a water heater in continuous operation is 2-3 years, constantly removing and re-hanging it requires a lot of time and money, as well as possible repairs. Secondly, a water heater standing on the floor is much easier to access for maintenance.
