I've got a Ferroli Arena 30C condensing combi that's nearly a year old. I installed the pipe work and rads myself and got a British Gas fitter to commission the boiler on the side. All has worked fine for the first 11 months, but every now and then when it's just finished producing hot water and the tap has been shut off it makes a vibrating noise from the boiler itself.
I've tried reducing the incoming water pressure, but that's made no difference. Only makes the noise when producing hot water, CH is fine, as we've noticed it more recently when the CH hasn't been on due to the warmer weather.
Any ideas, or is it just asking for it's first service a little early? Also, on this matter am I better to get Ferroli in to do servicing, or just get AN Other plumber from the Yellow pages or similar?
