I am in the process of replacing my oil fired boiler and since I personally do not work on them and have never installed one I thought it would be best to let the company that delivers me oil do it. I have checked with them as well as another service company and I am confused about what they are recommending. Bottom line is I am looking for a boiler manufacturer recommendation . Every service installer has their favorites but none of them agree on what boiler manufacturer is best. Any suggestions?
