Bosch Thermotechnology Ltd. Approvals


#1912804

Range of wall mounted combination boilers providing domestic hot water via a plate heat exchanger and pressurised central heating system, incorporating a pressure relief valve set at 3.0 bar and expansion vessel. The domestic cold water inlet incorporate a ½” BSP(M) brass body spherical valve. Maximum working pressure of 2.5 bar (primary) and 10.0 bar (secondary). Maximum operating outlet temperature (DHW) 85°C. Maximum inlet temperature (DHW) 60°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.
