Mainsboost is designed to stabilise water pressure and increase flow to combination boilers and unvented systems allowing multiple taps and showers to be open at the same time without a loss in performance.

If the property has good dynamic water pressure above 2.0 bar but poor flow rates or has more than one bathroom, this system will boost water flow performance throughout the property allowing combination boilers and unvented systems to work at their optimum, providing the property owner with all the benefits of having multiple taps and showers open at the same time.

Mainsboost systems are supplied with up to three vessels as standard, include vessel sizes from 100 - 1000 litres and are available in vertical or horizontal options, delivering flow rates up to 80 litres/minute per vessel.

Mainsboost is installed directly onto the incoming water supply and under mains pressure fills with water. The CAD2 water chamber is surrounded by a 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 now has a volume of pressurised water ready for distribution throughout the property.
