My mum has a Vaillant Ecotech boiler controlled by a wired VRC400 stat with weather compensation. It's started playing up with temperatures in the house when it's supposed to be 'off' being too high and the heating bill has shot through the roof. We could never work out how to use the thing anyway so I am happy to be replacing it. Our friendly Vaillant man suggested a VRC470 as a local stockist is clearing old (new) stock at £100 and he reckons it's more or less a straight swap and will be easier to use. However, I've been looking on the internet (and here) and there are suggestions that the Vaillant vSmart may be a better option - can more the thermostat into any room and can control it via a mobile phone. Then I saw someone selling a vSmart to replace it with a Drayton Wiser so they could control the radiators independently. Looking further I saw the Vaillant sensoHOME VRT380 which looks reasonably user friendly and would use the existing weather compensation wire.
I'm pondering which would be the best replacement considering ease of use and energy efficiency (thinking of weather comp possibly) so was looking for a bit of advice. I was thinking going with a Vaillant solution should mean it is more integrated.
