Hi - I have the (apparently) dreaded twin entry valve radiators. I really would like to get rid of my immersion heater (to make additional room in a new bathroom) so I believe I can't have a combi boiler with these old twin entry valves.

Having had a chat with my heating engineer this week, and a further chat with a very helpful person at Vaillant support, I'm now feeling confident that the Spirotech Spirocross AX100 LLH is the way to go with my CH enhancements. It's a little pricey but does provide the additional air and dirt...
