I turned on my heat upstairs in my house for the first time this season and I keep getting a weird noise come from the baseboard. It's sort of a grinding noise. It happens as soon as I turn on the heat via the thermostat up there. The heat works fine both downstairs and up but I get this noise when I first turn the heat on upstairs as well as from time to time. It's an oil furnance. Any ideas?

The weird noise sounds like a coin tapping against a pipe very fast. Sorry this is the best I can describe it. :)

It a common sound when the pipes or element is heating up fast- it is the medal expanding. If it stops after the heat has been on for awhile, I would say that's what it is. There are usually some type of "spacers" that let the element move in the mounts without making any noise- they may be worn.

hotwater heating i am guessing. the pipe actually slides from side to side as at grows longer with the heat on. there was a

ask thi s ol d hou se episode where they put in new guides in the baseboards in that episode ,it was really noisy before the new guides.

same goes for electric where the guides on the ends have slipped to the side.
