My existing vented cylinder is some 40+ years old and is convection ('gravity') fed (3/4" pipe) from the oil boiler. The boiler is a modern (7 year old) Worcester Bosch. Would I be right in assuming the cylinder is indirect?
Do I have a choice on whether the new cylinder is direct or indirect?
Will I need to have the new system primary pumped? As the boiler is designed for gravity primary is there any potential problem in fitting a pump - can I just fit a pump at the cylinder on the flow side - between the expansion tee and the cylinder inlet?
Is the pump to be controlled by the cylinder stat and if so do I need some sort of protection for the boiler such as a bypass valve to come on when the pump is stopped?
The existing boiler does not require a heat sink, though one is fitted (bathroom radiator).
thanks
