Unvented Hot Water Cylinder Installation in Bradford

Installation and servicing of unvented hot water cylinders in Bradford must be carried out by a G3-qualified engineer. This is a legal requirement under Building Regulations Part G. Our engineer holds the G3 qualification and self-certifies all installations.

A vented cylinder relies on a cold water tank in the loft for gravity-fed pressure — giving low pressure at taps and showers. An unvented cylinder is fed directly from the mains, giving full mains-pressure hot water to every outlet. Unvented systems eliminate the need for a cold water tank.

An unvented cylinder must be serviced annually by a G3-qualified engineer. The service includes checking the pressure relief valve, expansion vessel, and all safety devices. Failure to service an unvented cylinder annually can void the manufacturer warranty and create a safety risk.

Yes — unvented cylinders are commonly installed in flats and apartments in Bradford where loft space for a cold water tank is not available. We can assess your mains pressure and recommend the correct cylinder size for your property.

Yes. Unvented systems must have a tundish and an external discharge pipe so that, in the rare event the pressure relief valve activates, hot water is safely directed outside rather than into the property. Positioning it correctly — away from doorways and paths — is part of a compliant G3 installation, which we handle as standard.
