Word Heat Cylinders were establishing in 2008 in the wake of the closures of highly specialized hot water cylinder manufacturers Manchester Coppersmiths and Manchester Calorifiers by a large PLC who acquired both businesses. Since opening we have established ourselves as the specialist cylinder manufacturer in the UK, manufacturing vessels from stainless steel, copper and mild steel up to 8000 litres in capacity. All of our products are designed, manufactured and tested in our purpose built factory in Manchester. Our products are WRAS approved, CE marked and manufactured to be pressure equipment directive compliant.
