Installing Water Heater On Concrete Floor

Easy floor heat using a new or used hot water heater here i have a quick overview of my floor heating using a hot water heater as the heat source.

Installing water heater on concrete floor.

The system works via pex pipe a small pump a water heater and a thermostat. It is not necessary for electric water heaters or gas water heaters manufactured after mid 2003. Is it ok for a water heater to be sitting directly on a concrete floor rather than above it on blocks or. Either through pipes carrying hot water embedded in or directly below the floor or via electric mats in or below the floor.

The heat is made possible in two ways. I just had my 50 gas water heater replaced because it was 13 years old and i figured sooner or later it s gonna bust and flood the basement. I just had a new hot water heater installed and it is sitting directly on the concrete floor in my basement. The basement floor is concrete.

This is about installing hydronic radiant floor heating in a slab floor system. It just sits directly on the concrete floor. The code states that appliances having an ignition source shall be elevated not less than 18 inches 457 mm above the floor in garages and the purpose of this stipulation is fire safety. While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well.

Seems like i ve heard that s not a good idea to have electric water heaters installed directly on a concrete floor but can t recall the reasoning. They sat it directly on the floor not on blocks or a stand. I have never seen a hot water heater that was not sitting on legs or concrete blocks. Radiant heat can be an electrical heating element embedded into a very thin concrete overlay then tiled carpeted or have wood flooring installed over it.

The installer didn t bother putting anything under the electric water heater. Quite simply concrete floor radiant heat is a system of pex tubes that carry hot water throughout a concrete floor or slab. The floor drain is about 3 away. Instead of blowing hot air through a vent or pumping hot water to a baseboard radiator along the wall radiant heat warms up the entire floor.

I am just wondering if i should call the installer back and have him put it up on something.
