Hi, I was hoping to replace an old system boiler with a Vaillant Ecotec Exclusive 627 system boiler, thats the one with the diverter valve so no need for zone valves, controling it with a V-Smart and a VR10. I've spoken to Vaillant Tech and they said you cannot use the VR10 with a vented cylinder because of 'Water Regs', but I can't really understand why, when asked further he spoke about an unvented being designed to handle a higher pressure on the coil, but it is already pressurised so I don't really see what difference that'd make really.
The only obvious slight issue is that it won't have a dry pocket for the vr10 but I was wondering if it could just be taped to it then insulated aorund etc?
I was just hoping i could use the 627/V-Smart/Vr10 as i have once before [previously on an unvented] , as it seems a really good simple set up that provides DWHP when done.
Appreciate your thoughts
