Hi Guys
Cheers, ignore button found. Anyway yeah I got a certificate. Just looked at it and noticed it said carried out safety checks to cooker and serviced, same for the gas fire and same for cooker!! Seems a safety check and service is writing down the appliance details on a piece of paper. So I had one engineer arrive first thing in morning to tackle a rad or two that wasn't getting warm and fit/replace a few TRV's. He went in the loft and garage then started draining the system down from a radiator in one of the rooms. The other engineer from the same company arrived what about 3/4 to an hour later saying he was going to do the safety check. A bit odd as the previous one didn't expire until 3 months later. TBH I didnt see him with any tools just a tablet. I was in the livingroom when he worked on the gas fire, I didnt see any covers come off think he just started it and wrote the details down.
Anyway the problem turned out to be the CH pump was knackered and was replaced. All was ok the rad was now getting hot but other rads started banging repeatedly (when CH was on)like they were being hit with a metal hammer, mainly the largest in the livingroom but the small one in the kitchen aswell. The pipe is that microbore stuff. It drove us mad, at first I thought it was the rads moving on the brackets(no plastic seats) because now the rads were getting hotter and expanding more maybe. Tried stuffing towels behind them to see if it made a difference but it didnt. The engineer came back and his answer was to wedge a piece of 22mm copper pipe at an angle between the rad and the wall. Erm a bit ****e would you say? It fell off.
The noise from the rads got worse and I also noticed the boiler started banging and sounding really rough, you could feel the banging through the pipes. We ended up just using the fire in the livingroom for heat because the noise was like torture. The engineer came back when I wasnt there, spoke to him on the phone he said "the boiler sounds awful" and will speak to the agent. I noticed he had turned the CH pump to maximum. Anyway the boiler started tripping out on overheat. I rang them up and said send someone out, its an oldish boiler and we are in a very hard water area and I bet the heat exchanger is limescaled up. The engineer told me the plumbing in the loft was incorrect but not dangerous. I suspect the loud metallic banging was because of the kettling in the boiler causing heat pockets and different pressures that wasnt being absorbed by the system because there was no F+E pipe to the tank in the loft. Does this sound plausible?
They didnt do anything, it kept tripping, not often just like once a week. I spoke again and said show me proof of when the boiler was last serviced. This is when they said it was serviced at the same time as when they did the safety inspection. I said feck off did you, they sent me the gas safety record and sure enough it shows they did the safety check and serviced the boiler, fire and cooker. My arse I said. So thats where we are. I am certain a boiler cannot be serviced and safety checked whilst the system is draining down and thats what I came here to ask.
If someone could give me the practical and theoretical reason as to why this is impossible I would be very very grateful!!!
Sorry for such a waffle, its only one question really!!
