WRAS Approval Number: #2111364

Greenstar Heatslave II range of floor standing oil-fired condensing combination boilers providing domestic hot water via a plate heat exchanger and pressurised central heating system, which incorporates an expansion vessel and pressure relief valve set at 3.0 bar. The cold water inlet incorporates a screwdriver operated spherical valve followed by a plastic flow regulator inserted within the pipework. Maximum working pressure: Primary circuit 2.5 bar. Secondary circuit 10.0 bar. Maximum operating temperature 82°C.

Section:: 1465 Heaters
Section Subtitle:: Combination boilers and Water Jacketed Tube heaters. Low volume water content. Heat retained in water heaters will cause expansion of water after closure of draw-off taps and valves. Provision for expansion of water must be made to accommodate excess pressure within the system. Particular care is required where check valves are positioned, or loose jumper valves are thought to be upstream of the heater.
