NEXT LETTER RELATES TO FRAME SIZE OR PRIMARY CONTROL SET (PUMP & OR CONTROL VALVE) SIZE: Frame size - A, B or C. When fitted with a speed controlled primary pump add an i (3 and 4 port models only). When fitted with twin head primary pump add a D to model designation after the number xx. xx = number of (heat exchanger) plates All model names are followed by +0R where: +0R = no secondary pump. ## added to differentiate primary fluids and can be replaced with the following: SW = steam to water. LTHWS = low temperature heating to domestic hot water. MTHWS = medium temperature heating to domestic hot water. Units with a secondary pressure of 10.0 bar use stainless connections and are denoted by ’10 bar’ at end of model number. Units with a secondary pressure of 6.0 bar use bronze connections which are standard fitment so no addition or alteration to model number. All models can be fitted with either 1.5” or 2” secondary circuit connections, this does not affect the product model number.

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.

WRAS Approval Number:

2111364

Note:

Not supplied with a temporary filling loop. A filling loop must be installed with the appropriate backflow prevention device in accordance with clause G24.2, Guidance to the Water Supply (Water Fittings) Regulations 1999. R430 applies to the EXT models only.
