Caleffi pump issue

[maple1]

Boardroom, do you have your tanks plumbed in parallel or series? By series I mean the boiler goes into the top of one tank, and that tank's bottom connection goes to the top of the next, whose bottom goes back to the boiler. I think a series configuration might be more resistant to siphoning, but I'll have to think about that a bit more. In any event it will allow you to get more heat into the tanks when you do burn.

Any updates OP? Were you able to get the storage tanks charged up to see if it made a difference?
