I really want to save some money with the install of my wood boiler to my oil boiler. I have plenty of plumbing experience (sweating pipe, etc) so I'm running all the copper between the two boilers, hooking up the new circulator, and a few other odds and ends. However, since I have NO experience with draining and filling a boiler, I wanted a plumber to make the tie-in's to my existing boiler for me and have him drain/fill/bleed the system. After all - we're still in the middle of winter and I have a wife and baby in the house....
With that said... I'm still thinking about making the tie-in's myself since it will save me about $400 bucks and looks easy to me. Adding the Tee's (tie-in's) to the existing piping is a no-brainer for me but how difficult is it to fill and bleed the system when I'm done?? Do I just open the air vent over the expansion tank???? Should I open the pressure blow off valve and maybe even the check valves too?? My worse fear is getting it all back together and getting air locked or something that prevents the system from re-heating the home!
Any advice will be greatly appreciated. I've provided some pictures below so you can get a better idea of what I'm working with.
