Chaffoteaux & Maury Britony combi 80 type C12?

I am having the same problem with our Britony Combi (C&M) I think. Weird thing is we have plenty of hot water when the weather is warmer, so I am now suspicious that the d*mn thing just isn't effective eough at heating water from very low temperatures. This has been happening for 3 years and I'm getting a bit fed up. Got an engineer round once and he changed a couple of parts but as soon as the weather got colder it happened again. Grrr!

I am finding the same problem as Larry, CH works great, H/W demand and the water is stone cold, boiler fires seems to send water around the heating side and not through the Calorifier, Is there a water flow switch or diverter valve arrangment any ideas help me an all..Jono
