Product Description

Mainsboost MB 100SV-1-22 - Mains Water Boosting System Vessel

Mainsboost products are a flexible solution assisting with unvented systems (mains pressure) where the incoming mains pressure to the property is low or intermittent. Ideally suited for boosting cold water mains supply to residential, commercial and industrial properties.

The MB 100SV-1-22 is designed for unvented cylinders and combination boilers where the mains pressure is greater than 2.0 bar, but the water flow is inadequate for the requirements.

Installed directly onto the incoming water supply and under mains pressure, the vessel fills with water, creating a state of pressure equilibrium within the chamber (as it's surrounded by positive pre-charged air pressure sealed within the vessel, balancing them out). The Mainsboost system now has a volume of pressurised water ready for distribution throughout the property.

If greater demand is required, Mainsboost can be supplied with multiple vessel options.
