I just bought my house last year. The previous owner had just replaced the boiler before I closed. I had oil delivered the day that I moved in. I had problems with the hot water right away as it would only get hot when I turned the heat all the way up. I had a plumber come, and he said during the installation they crossed two wires. He was only downstairs few minutes and it was fixed and that didn't make sense to me, but I didn't ask questions because it was working.

Now it's a year later and it's happening again. I checked to make sure the water level was okay, which it was. I've bled the water and filled it again to make sure there was no air. That made it normal and hot again, but it only lasted for two days. It seems to be something very small that I am missing here because if it was wires they would not have crossed again. Now, I don't know if it was just coincidence that this happened on the same day that I had oil added again when it was very low. Should I bleed the oil line? Is there an adjustment valve or something that I am missing here? Please if any could help me it would be greatly appreciated.

-1 because this reads more like a rant and life story than a question. You should edit this to describe your boiler configuration, explain your problem, and ask your question as concisely as possible. – BMitch Mar 18 '13 at 1:22
Just to your last "question": That is correct. If you ran the oil tank low enough that the burner's oil pump lost prime, this would prevent the boiler's burner from firing at all. This would prevent you from having heat AND hot water both. – Tim B Mar 18 '13 at 2:44
It's not likely somebody on the other side of the internet will be able to fix your problem, especially with the limited amount of information you've provided. You're likely going to have to contact a local plumber to come have a look. – Tester101 Mar 18 '13 at 12:43
