I've been lurking here for a while and have become "hooked" at the idea of switching to a gasifier with storage from my current Shaver OWB. I like the idea of using a substantial amount less wood and having a boiler in a shed where it will be easier/warmer to fill. I have the opportunity to pick up a two year old Seton for a very reasonable price from a friend. While I know that there are newer and better units I feel the Seton will be a substantial step in the right direction. I am a little perplexed how to plumb this in as I will be making the switch to a pressurized system. I have Central boiler Thermopex running from my house to the boiler pad. In my home I have conventional pex (Non-O2 barrier) and a loop feeding a water-to-air heat exchanger in my ductwork along with a plate heat exchanger for my hot water. I am confused how to get the fill water to the Seton from the house without digging the yard up and running another water line. I understand that when i am done I will essentially have two closed pressurized loops, one boiler side and my house loop. If I put an automatic fill valve on the house loop can I put a second one on the boiler and fill the boiler from the house loop?
The second thought I had was to remove the heat exchanger from the back of the Seton and plumb my Thermopex directly into the boiler. I would just put the plate inside my house but could also put the fill valve for the boiler in the house.
I will probably install the storage tank next year but that shouldn't be a big deal to add plumbing wise and there is plenty on info on here about how to do that. I am also seeing in the Greenwood manual (being its a copy of the Seton) that you can run the boiler as an open system with a gravity tank to eliminate concerns about overheating during power outages. Which is better for this type of system?
sorry for all of the questions but I appreciate any help.
