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.
