Hi there, kinda new here looking for advice.
I am looking to install a used indoor wood boiler in conjunction with my oil boiler.
I have researched up and down but need someone to dumb it down for me lol as well as maybe provide some links to parts. Also, I have not yet purchased a used boiler yet so any advice there's appreciated. I need this to be as inexpensive as possible while still being safe.
I understand the boiler needs to plumb in with my current boiler in parallel using "closely spaced tees" I assume that means the out and return from the wood boiler plumb into the main loop basically side by side????
I also understand i need a "heat dump" that can dissipate the full btu of the boiler in case of power outage or radiators not calling for heat. What would this look like? What parts are needed here?
Diagrams of how to plumb this would be super helpful. I am no dummy and I'm not scared to do this, just want to make sure I do it right.
Thanks.
