Mains Water Boosting System

The MAINSBOOST MB 250SH-1 is designed for 'direct on mains' systems (unvented hot water cylinders and combination boilers) where the incoming mains pressure is greater than 2.5 bar but the flow is insufficient to meet demand.
Supplied with a mounting cradle, these vessel systems are installed horizontally and are ideal for use under the eaves in loft spaces.
MAINSBOOST vessel systems do not require an electrical supply and operate silently.

System cold water storage capacity can be expanded simply by adding one or more MAINSBOOST Add-on units as required.
If the incoming mains water pressure is less than 2.5 bar, a MAINSBOOST Charger pump can be used in conjunction with the MAINSBOOST vessel system to boost pressure.

The MAINSBOOST MB 250SH-1 features a nominal vessel size of 250 litres and a pressurised cold water water storage capacity of approximately 137 litres.
Each unit is supplied with the unique compact MAINSBOOST Monobloc 22/28mm Upstream Kit (USK) as standard which significantly simplifies installation.
