I just called some of the HVAC companies in my area for general boiler maintenace and they all see a little out of my price range for a fully functional, very effient running boiler.
My problem is, it is hard for me to find information on how to perform general DIY maintenance on a boiler.
My first question is how often should the expansion tank be recharged? It is a steel horizonal style one. I got information on how to do it here: http://homerepair.about.com/od/heatingcoolingrepair/ss/boier_exp_tank_2.htm
Second question is how often and what type of lubricating oil should I use for this boiler? I had a friend tell me to oil it before I turned it on next, and I found where the oil goes, but have no idea what type and how often?
As a rule of thumb I will eventually get a professional to come out and ensure the unit is safely operating. What would you suggest, like, every 5 years?
Thanks guys, I appreciate the help!
