Coalkirk, I'm hoping the changes I've done at the end of season will help . Underground piping isn't issue because when it snows it doesn't melt off. House is insulated and 80% windows have been replaced. Are you running yr round? First 7 ton of rice had allot of barley in it, next 5 ton of buck was size with no fines at all. Circulator was running 24-7 until end of season, it's now running on demand only.
I do not run year round. Normally start at the end of October thorugh April. This year I started the second week of October due to colder weather. We did use about another half ton this year as a result. My boiler is also in the basement which helps alot. I insulated all of my basement walls with Rmax board and then the portion that is finsihed also has R13 fiberglass so basement walls are in the area of R19. R30 in the attic. All but a couple of windows have been replaced.
When you factor in your boiler being in an outbuilding and your underground pipes, your results make more sense. Basically you are heating that building and you do lose some heat in the underground pipes. I assume they are insulated and buried below frost line?
