Hi all
Just seeing if this is a common method of providing a boiler bypass thesedays as there seems so many ideas out there, years ago if we needed a bypass a gate valve was the answer but no longer classed efficient and others not suitable due to the smart pump.
The system is a sealed single zone heating system and indirect hot water cylinder using a Grunfoss Alpha smart pump. The H/W zone valve is controlled by an ST9100C timer, a tank stat and the mandatory thermal cut out whilst the heating by a CM907 programmable thermostat. There is a mid position valve that in its static position provides the bypass for the boiler and when powered by either of the zone valves fully opens to direct boiler flow through the required circuit and providing power to the boiler. There is also the usual frost stats and pipe stat for protection.
Anyone got any comments or feedback ?
thanks Roy
