Section Code 1360 : Electric instantaneous, mains fed, closed outlet. Heat retained in instantaneous 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.
