Glowgreen why on earth did we get a boiler from this hapless company. From the day the boiler was fitted (an eyesore) it did not work properly. 3 engineers later it was sort of working. The last engineer Britannia Building services (excellent) told us the piping was all wrong and that the 1st engineer should've known that. Anyway because of all the issues Glowgreen gave us a free wireless upgrade, the only problem with that was that the control unit is not compatible with the wired thermostat, the upgrade they sent was 2 parts should've been 3 bits to the upgrade. We cannot set the heating to come on or turn off using the control panel, we have to turn it on and off manually. I've contacted customer services about this and they want to charge a call out fee of £144 to try and prove its operator error. I've already told them that the engineer who fitted the upgrade said that we would not be able to set the heating to turn on and off. So I replied and said I'm not paying £144 for someone to come out and fund out I am right about a wrong fitted system. No reply to that email as yet.
