Mains Water Boosting System

The MAINSBOOST MB 300SV-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.
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 300SV-1 features a nominal vessel size of 300 litres and a pressurised cold water water storage capacity of approximately 165 litres.
Each unit is supplied with the unique compact MAINSBOOST Monobloc 22/28mm Upstream Kit (USK) as standard which significantly simplifies installation.

Constructed from an epoxy coated steel body and a highly durable virgin butyl diaphragm, all MAINSBOOST vessels are supplied with a 5 year warranty.
