Hi, This is my first post here (newb). I bought a house in Northeast CT last year which had a combination boiler system with a Weil McClain Gold WTGO Series 3 (Oil fired with tankless coil) in connection with a Northland Boiler W 1010 Indoor wood Boiler (Company originally based out of East Haddam, CT and now out of business). House is approximately 2500 sq ft and there are 5 heating zones.Its a pressurized system which supplies cast iron radiators. The wood boiler is in fabulous shape and unfortunately I don't think I am using it in an efficient way as I can't get my oil fired boiler to stop firing, even when I'm at 180-200 *F with the wood boiler. There are 4 single aquastats on the wood boiler. I know one is dedicated to the circulator but cant figure out which task the other 3 have ( high limit, low limit, overheat, other???). Is there anyone that is familiar with this boiler or has any literature at all? I am happy to post pics if it will help. Any help is greatly appreciated as I am burning through 1.5 -2 cord a month and I know I should be getting better results.
