Product Information:
"Why do I need a MainsBoost-plusWater Performance System"
  • The incoming water pressure to your property is OK (about 2Bar), but you would like more pressure - up to 3.5Bar
  • The shower fittings you have require a guaranteed minimum operating pressure.
  • You have large or high flow rate shower heads and/or the incoming water supply to your property is less than 2Bar (static/standing) pressure (so insufficient for a standard MainsBoost™ system.)
  • Your bathroom has shower body jets which require high water pressure and flow rate to give you the ultimate showering experience
"When should I install one?"

In some areas of the country water pressure is so poor that home owners have not been able to enjoy the benefits of unvented cylinders and combination boilers or the performance of the latest high end showers (which typically need at least 2Bar incoming water pressure to operate effectively).

The MainsBoost-plus™ can deliver up to 3.5Bar pressure and substantially increase flow rates to allow properties with even the lowest water pressure (0.5Bar minimum) to enjoy a 5 star experience from their combination boilers, unvented cylinders and high end performance showers

"How does it work?"

The MainsBoost-plus™ is primarily designed for properties with less than 2Bar water pressure at the stop tap but which require increased water pressure and flow rates to deliver the optimum performance from combination boilers, unvented cylinders and high performance showers.

The MainsBoost-plus™ combines the super-efficient MainsBoost™ Water Performance System with the innovative direct on mains Charger™ MJ3 pump to increase water pressure (up to 3.5Bar) and improve flow rates to all direct on mains appliances. The Charger MJ3 pumps a water regulations compliant 12lpm water from the main into the MainsBoost™ vessel. If the incoming main provides more than 12lpm, the surplus is diverted through a ‘Green Energy’ by-pass directly into the MainsBoost™ unit.

The MainsBoost-plus™ can be connected to one or more MainsBoost™ Add On Units to provide increased water storage to meet larger household water demands.
