Can an unvented hot water cylinder be installed in a loft?
Anonymous user 28/02/2024 - 3.11 PM
We have recently had a garage converted to a single storey annex. The hot water cylinder is unvented (Joule Cyclone 125) and installed with all the necessary pressure relief valves and containers in the loft. An OFTEC engineer came to inspect and commission the boiler and stated the cylinder was a potential bomb as it was unprotected from frost and said it would be best to relocate the cylinder on the ground floor. Can the cylinder be protected or would it safer to relocate it? --------------> I have since spoken to the water cylinder manufacturer and have been informed that the cylinder has a 50mm poly internal insulation, it is safe to leave in loft as long as the discharge pipe to the outside is well insulated.
Are you a tradesperson and able to answer this question?
