Mainsboost

Mainsboost MB Mainsboost systems are designed to stablise water pressure and increase flow to combination boilers and unvented systems allowing multiple taps and showers to be used at the same time. Designed for unvented systems where the mains pressure is greater than 2.0bar but water flow is inadequate. Mainsboost is installed directly onto the incoming water supply and under mains pressure fills with water. The CAD2 water chamber is surrounded by positive pre-charged air pressure sealed within the vessel. When the chamber is full the unit reaches a state of pressure equilibrium, meaning the water pressure and pre-charge pressure are balanced. The Mainsboost system nos has a volume of pressurised water ready for distribution throughout the property and where required can be supplied with multiple vessel options. Where space is an issue, Mainsboost is also available in a range of horizontal sizes to suit the application requirements and re supplied with an additional mounting cradle. Mainsboost systems can be supplied with up to three vessels as standard, included vessels from 100 to 1000 litres and flow rates up to 80 litres/minute.
