Space below cylinder?

[Cello]

Replacing an ancient copper hot water cylinder. The airing cupboard has a fully boarded floor and the cylinder is supported on three bearers, resting on the floor, each approximately an inch and a half wide by two inches high. I question whether bearers are needed? Can I just put the new cylinder on the floor or is there a good reason why a space is needed below the cylinder?

The cylinder needs to be on batons to ventilate the bottom to stop corrosion.

Sorry ch 4 totaly disagree, stresses the cylinder.

Seen plenty pin holed at the bottom when sat straight on the floor, especially on concrete.

how many old cylinders do you see straight on the timber boards and these new unvented cylinders you put straight on the floor as well

Very rarely see a copper cylinder straight on the floor, unvented cylinders should be sat straight on the floor no question about that.

Yep agree not straight on to concrete, its similar to why we put cwsc's on solid bases with 150mm overhang, they are fully supported.

I was always taught to have vented cylinders raised to allow air circulation

I always thought that gap underneath was for hiding mucky mags..

I was taught it was to stop the cylinder sweating? Always done it and never seen a cylinder suffer for it.

as an apprentice on new build sites back in the day, we always put the cylinders on 3x2 battens made into a cross by the joiners.
