Yesterday we had an "installer" come and try to install a new WB Greenstar 25 boiler while I was at work. When I got home, my wife said that it didn't work when he tried connecting it to the fused spur switch, so he then tried adding a three pin plug to it, but that kept tripping the the fuse box RCD. And then he went home, leaving the boiler disconnected from the electricity but connected to the gas and water (he took the plug off before going home). With no sign of any sort.
I went over to have a closer look at the boiler and immediately noticed the smell of gas. I shut off the mains gas, we called Transco and luckily the Transco guy was able to tighten the pipe and close the leak without having to do some more major isolation work.
So far so bad. I then had a look at the wireless thermostat he had wired in and it was immediately obvious that he has connected the earth lead from the boiler into the second live connection on the thermostat (no idea why it has two but it does). This would explain why the boiler didn't work, and why the RCD kept tripping. Indeed testing the live and earth wires on the 3 core wire hanging out of the boiler shows a short circuit.
We are tenants, and so I don't pay for any work, but we have been without heating and water for over a week now so I'm interested in the quickest way to get to a resolution. The question I have is this.
1. How likely is it that the above has fried the boiler circuit board? The boiler fuse is still working, but is it possible that the RCD has been unsuccessful in protecting the circuit board from the short the installer put in?
2. Would you trust an installation completed by this installer, whenever he does eventually manage to figure it out, or should I push to have a second opinion given all of the above?
Many thanks in advance.
