Hello I have an 8yo old baxi duotec combi 24he boiler. When the gas central heating is running, it makes a constant loud high pitched humming/whinning noise. The noise only quietens for about 5 seconds, each time the boiler reignites to heat the radiator water. Before then returning to the same level.
I am in the room above the boiler, the noise is quite loud and its persistence gives me ringing ears. [see the link to hear the noise, recorded upstairs. the recording does not capture how loud the note is, only its tone ]. https://drive.google.com/file/d/0B2It1x ... sp=sharing
Further info, If the central heating is off, but the hot water tap is turned on. The boiler makes the same sound but at a much quieter level.
-- My questions: 1. What is the noise likely to be coming from in the boiler? [or where has similar noise come from in other related boilers] 2. And when I call out the baxi engineer again, to attempt to identify the noise source. What are the likely parts, where they should first start their fault finding?
Hi i have seen your post on the noisy baxi boiler. I have exactly the same issue the boiler is a baxi plantinum and was fine up until recently a high pitched humming droning noise started and wont stop ..Could you please tell me how you resolved the issue what was the fault and what price roughly . Thanks in advance John
