We recently moved into a house and are running the heat for the first time. It's a gas-powered hot-water heat system with a single-loop design.
(1) When the heat turns on -- and especially in the middle of the night when I'm slepping -- there's a loud pinging-type noise in the baseboard heat of our bedroom. It's similar in sound to if you flicked your finger off of the wall. Our boiler self-purges air bubbles, so it shouldn't be related to excess air in the system that would have to be bled. I know that the copper tubing expands and contracts a bit when the water heats or cools, but I'm hoping that I can do SOMETHING to stop the pinging so that I can sleep through the night rather than being awakened everytime the heat comes on. Can anyone help me trouble-shoot the problem?
(2) Our pilot light wouldn't light at all, so we called in a plumber, who replaced the wire sensor (the name is escaping me) that goes into the pilot light, but that didn't solve it. So he then replaced the gas valve, which seemed to do the trick because the pilot lit and the system worked for 5 days. The system worked last night (because it woke me up with the pinging...) but then the pilot went out this morning. I re-lit it, but don't want to have to keep re-lighting. The plumber said he can't think of anything else that might be causing this. Our hot water heater is about 6 feet away and its pilot stays lit, so it shouldn't be a sudden drop in gas pressure from the gas provider or even a draft. Any thoughts on this one?
Many thanks for any advice, tips or guidance!
