Mainsboost Plus

Mainsboost Plus

Mainsboost Plus systems combine all the efficiency of the patented Mainsboost vessel with an innovative vessel mounted direct on mains pump to offer both increased water pressure and flow.

Designed to deliver up to 3.5 bar pressure and increased flow rates throughout the property, Mainsboost Plus systems will provide a consistent and much improved water performance to all direct on mains appliances.

Suitable for unvented systems where pressure is less than 2.0 bar and water flow is insufficient. The WRAS approved Mainsboost Plus water performance system utilises the Mainsboost system's accumulator technology, supported by an innovative direct on mains Charger pump to provide up to 744 litres of water stored at pressure.

Mainsboost Plus improves water performance throughout the property by increasing water pressure up to 3.5 bar and flow rates up to 80 litres per minute (per vessel) allowing unvented systems and combination boilers to perform as intended and offers the capability to run baths and showers at the same time with no reduction in pressure or flow.

Mainsboost Plus can be supplied with multiple vessels and is also available in a horizontal orientation for where space is restricted.
