I have been searching through the forum to try and find a similar question but can't find anything. I apologise if this has already been answered though.
I have a Potterton Promax boiler coupled to a Gledhill Boilermate A-class storage system which was installed in our brand new house 6 years ago.
Last week we had our annual boiler service. This usually takes a good hour, so I was surprised that this time it only took 10 mins. The next day we realised that we had no hot water. Of course, I called the service company, who told me to press the reset button on the boiler and sure enough, the boiler kicked in again.
However, since obviously, at this time of year, we don't have the heating on, it was only when we tried to shower, the following morning, we realised that yet again, the boiler had cut out. We were able to reset it each time, but it seemed to cut out every 10 minutes or so, never heating enough water hot enough for a bath or shower.
We managed to get the same heating engineer back, 3 days after the service, who just did exactly the same thing. He pressed the reset button, claimed it was now working and left, despite us telling him that it would cut out again by the time he was at the end of the road! And it did!
Since we have emergency breakdown cover with the same company, we finally managed to get them to send out a different engineer. After having a good look, he said that the system needed to be powerflushed. He said that there was a lot of black gunk in the radiators, causing the system to overheat and shut down after 10 mins or so. He vented off a few of the radiators, saying that getting rid of an airlock could temporarily help the problem and it might not cut out so soon this time, but a powerflush was necessary and he also said that he thought that our builders probably hadn't put an inhibitor in...................we would have no comeback on this because it is now 6 years since the house was built.
I can see some logic in what the engineer was saying, and to be fair, his company were not trying to sell us the powerflush. But it seems like a lot of money to have to spend.................could he just not be bothered to find the problem? Also - there wasn't any problem until the boiler service last week. Is it just a coincidence? All the radiators work well - no problems with cold spots or anything.
Any help, guidance or reassurance would be greatly appreciated. Thanks.
