Vokera Linea hot water problem

carebear1976

My combi boiler (less than two years old) has recently developed a problem in that it is only heating up the hot water to 30-40 degrees and then cutting out. The water temp then drops to around 25 and the boiler kicks back in until it hits 30 or so, then cuts out again (about 10 secs each way).
I understand that one reason may be that the heat exchanger needs to be cleaned (a common fault with these boilers apparently) although I am guessing there could be other reasons.

Would anyone have a rough idea of what I should expect to pay a gas-safe engineer to clean the heat exchanger? Alternatively, if you have any other ideas of what the problem might be, I'd be glad to hear them.

I am in Glasgow, so if anyone is willing to recommend an engineer please feel free to pm me.
Thanks!

Any ideas anyone?

we have a vokera linea and have had it break twice in the middle of winter with very young children. Last time our gas man checked it out and told us to take out vokeras own coverplan which covers you for one repiar parts and labour and gaurantees that part and the repair for the whole year, this was about a third of the price of the part we needed and cheaper than our local gas man could do, well worth it for us at just over £100, good luck. We are going to take out boiler cover as it is quite cheap at the moment.

Likely to be a thermistor problem which is a straight forward replacement. Hardly anything has to be dismantled.
