First off I tried searching for thread, I'm sure this has been discussed before.
Anyway, I'm in the process of figuring out what direction I want to go in adding wood heat to my house.
I've got two boilers in mind, either a Scandtec Solo or a Tarm Solo Innova. I know I can get some others cheaper but the local outfit carries these models and both the brands and the reseller have good reputations.
At first I was going to try and make a go of it with out storage (which would have limited me to the Scandtec) and then add storage later on down the road. I've sort of back tracked on that now and I think I'm going to just try and get the plumbing done in one shot.
So that leads me to my question, pressurized or unpressurized storage and what the advantages of one over the other?
I think the big one that I can see is generally pressurized is going to be cheaper, especially if you can source used tanks. You do have the hassle of converting them and dealing with expansion though. I've been looking for tanks locally just to see what's out there and used is close to impossible to get your hands on. Everyone would happily sell me a new one though!
Unpressurized seems to leave you with more options (solar, easier to add domestic hot water, etc) but the cost is more.
What else am I missing?
Thanks,
K
