LCB700 range of internal and external oil-fired condensing combination boilers providing domestic hot water and pressurised central heating via a plate heat exchanger. The products are supplied with a temporary filling loop which incorporates a combined isolation valve and double check valve assembly (suitable for backflow protection against Fluid Category 3), stainless steel braided EPDM lined flexible hose assembly and an isolation valve. The primary (space heating) circuit incorporates an expansion vessel and a pressure relief valve (set at 3.0 bar). Operating parameters: Primary (space heating) circuit: Maximum working pressure 2.5 Bar. Maximum operating temperature 105°C. Secondary (DHW) circuit: Maximum working pressure 10.0 Bar. Maximum operating temperature 85°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.
