"Silent and efficient"
I have owned this boiler for 3 years now and have had no problems with it. It is quiet enough that my children in the next room are not awoken by it, and it is efficient enough to save me substantially on my utilities bills compared to when I had my last boiler. I would certainly recommend this brand to a friend, as it has definitely paid for itself in savings. I do not necessarily dislike anything about it. I would certainly buy an Accel brand boiler again. I have never needed a repair.
