(Both for gen set block heating and for dumping exhaust heat). For thermal storage, they have an old dairy bulk tank in a walled off room with truck radiators in the tank connected to manifolds out side the room. the whole room was filled with recycled styrofoam peanuts. the tank loop is connected to the boiler, a kitchen wood stove and a radiant slab, the radiator manifolds are connected closed loop to SHW on the roof and domestic hot water.

</style>I have a Central Boiler brand of outdoor wood furnace. It has an electric damper that has to be powered whenever the fire is burning, which draws about 50 watts and a small circulator pump that draws a bit less than 100 watts.<br>I stopped using it years ago because it consumed so much wood, but it worked great. It was a great way to get rid of pallets.<br>Unfortunately it was most needed whenever there was not much sun, so it definitely increased generator run time.<br>David Katz<br><br>Sent from my HTC smartphone on the Now Network from Sprint!<br><br><br><div id="htc_header" style="">----- Reply message -----<br>From: "Ron @ earthRight Solar" <<a href="mailto:solareagle@solareagle.com">solareagle@solareagle.com</a>><br>To: "RE-wrenches" <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>><br>Subject: [RE-wrenches] Outdoor woodstove/furnace and solar<br>Date: Wed, Jul 4, 2012 4:48 pm<br><br></div><br><br> <font size="2"><div class="PlainText">Hi Wrenches,<br> <br> Have a client who wants to install an outdoor wood furnace for hydronic heating in his shop and home.
