Mains Liquid Boosting Setup

The MAINSBOOST MB 450SV-1 is intended 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 pumps as required. 
If the incoming mains water pressure is less than 2.5 bar., a MAINSBOOST Charger pump can be utilised in conjunction with the MAINSBOOST vessel system to boost pressure.

The MAINSBOOST MB 450SV-1 features a nominal vessel size of 450 litres and a pressurised cold water water storage capacity of approximately 248 litres.
Each pump 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.

The Mainsboost MB 450SV features a nominal vessel size of 450 litres and a pressurised water holding capacity of approximately 248 litres. 

Constructed from an epoxy coated steel body and a highly durable virgin butyl diaphragm, all Mainsboost vessels are WRAS Approved and come with a 5 year guarantee.
