Peerless Boiler Pf140 sound
I do have my boiler cleaned and checked each year. Sometimes when its warmer outside and water temp is warmer due to an outside sensor. Sometimes I hear like not enough gas and once in a great while a hear a louder boom from the boiler. I've had the company check it out and they say everything checks out. Any ideas? I've also had two different repair places out but I think both have no knowledge on these high efficient boilers.
