Boilers - Home Heating Steam and Hot Water Systems
Boiler System with Banging Pipes - HELP

P

pabadear on Jan 25, 2019

Hello everyone, New home owner for 1.5 years now and this is my 2nd winter in the house. Last year we experienced loud banging noises in the walls during the night when we had the heat running. After some googling, I decided to purge the system, which consists of 2 zones (1 for the first floor which is living space and 1 for the 2nd floor which is the bedrooms). Purging both zones eliminated the banging the very first time so my wife and I were extremely satisfied. Fast forward to this winter, same thing again - loud banging noise during the night. We've purged the system 4 or 5 times now but we haven't had a single night pass where we don't hear anything. And the noise is intense, it's as if someone is knocking on your bedroom window over and over and over for 10-15 straight seconds. What could it be and is there any troubleshooting that can be done before calling in a professional? I've tried to let the system purge longer periods and waiting for a pocket of air to come out that may possibly be at the opposite end of the house but I'm scared/uneducated on how long I can purge for before potentially damaging the system or even worse, the house. I can't find anything online that tells me to monitor something while purging such as pressure or how long I can purge for. Can I just keep purging till the system dries out completely? Can it even dry out completely or is it constantly replenishing water? The system typically runs at around 30-35 psi till I shut it off to purge, at which point it gradually drops to 0 psi. Any help is appreciated!Read More

The air pressure fluctuates and then drops and the burner cuts off. What is causing the air pressure to do this? Could it be the air pressure switch?Read More
