Range of wall hung, gas-fired condensing combination boilers providing domestic hot water via a plate heat exchanger. The pressurised central heating system incorporates an expansion vessel and pressure relief valve set at 3.0 bar. The supplies to both domestic hot water and primary are controlled via spherical valves. The primary circuit has a maximum working pressure of 2.5 bar. The secondary circuit has maximum working pressure of 10.0 bar. Maximum supply temperature is 60°C. Maximum operating temperature of secondary circuit is 85°C.

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.
