I was wondering if I could get some advice on this topic. My house has oil heated forced hot water heating. Last year I mainly heated with the woodstove and found that on very cold nights I could hear this loud banging. It was very loud and sounded like someone hitting the house with a big hammer once every 10 -15 minutes in the same location. I believe this was the water pipes possibly near or at freezing. Can someone explain the cause of the banging? The pipes never did break so I believe I got lucky. I want to avoid this situation next year so I'm thinking about options. I did find that the basement was cold with no furnace running.
In the spring I also found the pipes for the banging zone in the basement near the sill needed more insulation so I took care of them. It may help. Generally the house is well insulated. Do some houses with forced hot water have no issues when the boiler doesn't run at all?
I have read that placing boiler or RV antifreeze in the heating loops is one option. I was also thinking about the idea of running the zone circulator on a timer relay may be an option. Has anybody tried this method? Any other Ideas? Maybe I should heat the basement a little bit?
Thanks in advance
