About 15 years ago, I had the boiler replaced in our "new" home. During the installation process, an Automatic Vent Damper was installed on the exhaust duct to improve efficiency. Now, after 15 years, it has appeared to have "petered out". I purchased a new on over the internet, and installed it last night. (Luckily, it was "plug and play" with the existing wire harness.) However it is still not working properly. Initially, before it was replaced, the boiler would completely shut down. Pilot and all. I first tried to turn the breaker off and on. Nothing. Then I hit the little switch on top of the Automatic Vent Duct Motor and the furnace would kick on. That is how I concluded, something may be wrong with the AVD. Well, once I replaced the AVD, the boiler kicked right on and warmed up the house. However, once the house was warm and the water in the tank and pipes cooled, it did not automatically come back on. I attempted to "flick" the switch like I did on the one I replaced which, after a few flicks, the boiler would come on. However, with the new model, it did not. But, if I pinched the "shaft" of the damper and attempted to give it a twist, the slightest movement of the shaft turned on the boiler. Any ideas??? thank you!

I finally removed my underground oil tank and installed a Roth tank outside above ground. Its going to be the first time dealing with cold oil. I did pre-filter tigerloop set up so hopefully that will help a little. My question is does anyone have experience or opinions on tank heaters. here is a link at ones I am looking at.
