I have a Saber 24 it runs okay the radiators are hot, but the heat exchanger is very noisy, I changed the pump in case the pump was down on duty but this has made no difference. Any suggestions.
could be a blockage in the heat exchanger or the flow or return pipes coming off of it, or maybe it's the fan that's noisy, get a qualified engineer to have a look at it.
