Gledhill Boilermate Stainless OV schematic diagram

The BOILERMATE STAINLESS OV is an open vented thermal store design for use on a fully open vented heating system and is suitable for use with a heat only gas or an oil boiler. It is ideal for upgrading existing traditional hot water systems.

Easy to install, the BoilerMate OV is supplied Pre-Plumbed (PP). This makes installation simple and quick as pre-installed plumbing (includes zone valve, boiler circulating pump, plate heat exchanger and store pump) makes the install a simple plug and play exercise.

BoilermMate Stainless can be retro fitted to an existing system making it a great way to convert a traditional open vented gravity hot water system to mains pressure.

Unlike unvented cylinders, the BoilerMate OV Pre-Plumbed does not require expensive safety controls or the need to plumb temperature and pressure relief pipework to an outside wall.

Boilermate - Recognised by many of the UK's national

house builders

The Boilermate system has been widely used throughout the UK within the 'new-build' sector and by discerning householders for many years. Recognising the superior performance and advantages of the system over others, Boilermate has become a household name throughout the country.

Boilermate has evolved

Throughout many years of service the Boilermate system has passed through several evolutionary stages. Each upgraded model superseded all previous models. All though function has varied slightly over years the Boilermate's primary function of providing mains pressure hot water has remained a constant. The BOILERMATE BMST STAINLESS will be suitable to replace older models even if a small amount of adjustment to pipework is necessary.

Convert your present hot water system with Boilermate

Boilermate is also popular if you wish to convert an existing gravity hot water system to mains pressure. Being so easy to install Boilermate lends itself to retrofit, upgrading your household hot water system with little fuss.




If you are looking to upgrade your system (which can be done with consummate ease) or you wish to replace an earlier version of Boilermate you might like to call our office to learn more.
