I have a Concord WRS (Ieal) boiler, Potterton EP 3002 progranner on a gravity HW, pumped heating system.
If I wanted to change it to pumped Y plan (I may also change boiler to a Broag), do I just have to change the flow pipework to fit a mid pos. valve, and add a Y plan pack (wiring centre, programmer, stats, etc)? Or is there more to it?
What other changes would be needed? For instance, would I need to add a bypass, or if the Broag was fitted, would it alrady have a bypass?
Many thanks
