Mainsboost

Mainsboost systems are designed to stabilise 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 2.0 bar 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 now has a volume of pressurised water ready for distribution throughout the property and where required can be supplied with multiple vessels options. Where space is an issue, Mainsboost is also available in a range of horizontal sizes to suit the application requirements and are supplied with an additional mounting cradle.

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

Mainsboost pressure vessels are available with 22 mm or 28 mm Upstream Line-in Kits (ULK) kits as standard, with larger ULK sizes for commercial systems available on request.

Bespoke options are also available. For further information contact info@stpumps.co.uk

Mainsboost Charger Systems

Similarly, Mainsboost Charger systems are no longer listed as individual product configurations. Instead, the required Mainsboost units and wall mounted Mainsboost Charger MBC 12 pump must be ordered as separate items.

Example

For Mainsboost Charger System MBC 250SV-2-22 (44483), order Mainsboost MB 250SV-2-22 (44462) and MBC 12-22 (44725)
