We have an icos HE18 conventional condencing gas boiler we had to remove a radiator in the living room as the pipe was actually on the floor and we were fitting a laminate floor.We raised the radiator and added new pipework, the radiator is level and nothing is leaking. We bled all the radiators and all heated up fine when we put the heating back on. BUT ALAS WE HAVE A NOISE RESEMBLING A HOWLING WIND coming from the boiler now? We had it serviced 2 days ago and mentioned the noise to the service engineer. When he had left the boiler is still making this noise. Can anyone out there have any idea what can be the cause of this please, it's driving us mad
