alpha boiler

Hi, I.m looking to add a Nest Thermostat E to my Alpha Eco Boiler. The boiler has no room stat but just a timer. My understanding is that I should leave the timer in and set it to always on. I should then remove the link connecting 1 and 2 and run instead two wires from 1 to NO/Call for heat...

Today we had a visit from a BG engineer and his notes say replaced PRV in boiler. I assume this is a "pressure release valve" Anyway since he left when my hot water timer comes on to heat the tank its like a loud gurgling noise next to the 3 way valve in the cupboard upstrairs. Now when we...

I would be hugely grateful for some help with my boiler - Alpha CB28. It has some failure - it's trying to star when the water in on - sound like trying to start a fire but it goes off after 1-2 sec. Somebody advised that it could be a circuit board and that its probably better to put a new one...

Hi I have 2 problems, I've replaced the gland nut on the front of the DHW diverter valve, some 8 months ago, but it is now leaking again from the pin directly behind the micro switch, mainly when no heating has been on. In addition as the hot water takes a while to heat up, I have to put the...

Hi everyone, I'm new to the forum but I've been reading it for quite a while and I thought I would register today as I was looking to get some help on a problem and I couldn't find the solution online. I recently purchased a Nest thermostat (2nd gen), and I wanted to wire it up to the boiler...
