Unvented hot water cylinder Leighton Buzzard
Recently working on an invented hot water cylinder I noticed this label, i have seen what happens if you do not drain the unvented hot water tanks as instructed, as the water left in the tank cools , if there is no allowance for air to take up the contracted space the cylinder will literally fold up and crumple With no repair possible. That’s a large expense for someone !
