Scenario...
ICF basement, 12" double wall celluse insulated home.
2000sq ft.
Budget is tight
Ive read about 'wood gasification boilers'
Curious, is there any way to go from a more traditional wood stove to heating hot water for radiant heat in a cost effective way?
I have access to FREE wood but dont want a woodstove in the main portion of the house (wife hates the dirt, smell, mess, etc).
My father used his wood stove last year in the basement but just kept the cellar door open to let the heat up, im not sure how effective that was.
Anyhow, thought I would ask you very smart people here.

Years ago (1984) I lived in a 1,200 sq. ft., poorly insulated home in Pocatello, ID that had an oil furnace in the basement plus, sitting next to it, was a wood furnace which was about 15" wide, 26" long, and 18" high and was mounted on legs about 15" high from the floor. The walls were double with about an inch between the walls. Under the firebox was a small, squirrel cage blower on a thermostat that would blow air from the basement through this 1" space and out a 6" diameter duct located in the top. The duct then ran to the outlet duct of the oil furnace. The stove pipe exited the rear of the furnace. The only time that I ever used the oil in the winter would be if I were going to be gone for more than a day. As I recall, a cord or two of dry fir would last all winter. With this stove, all of the dirt was in the basement. A google search or maybe "Mother Earth" might turn up such a stove today. Good luck! |

John where are you located? I have a neighbor who has a wood gasification boiler, the only one I have seen. It is similar to those big wood furnace 'huts' that have become so common but much better, they say. They are supposed to burn real clean. Last I spoke with him he worked for the company, but that was in the fall and in these times you never know. |

Im in the Bangor Maine area, however I have researched Wood gasificiation boilers they are very nice, but expensive (average around 6-7k). I was hoping to heat water via a more traditional wood stove in the basement. It may not be feasible from what Im reading. |

There are lots of indoor wood boilers, cousins to the OWB kind. You can google that term and find some, but I'd ask the helpful folks at Hearth.com for some advice first. Go to the boiler forum.
The problem with a central heat wood boilers, even the gasifiers, is that they end up idling a good bit, which lowers efficiency and gooks up chimneys. Worse, when they kick in, they send up an amazing plume of particulates. Storage could smooth out demand. You'll find some DIY approaches here. http://builditsolar.com/Projects/SpaceHeating/Space_Heating.htm#Storage
Also note the masonry heaters under "biofuels" on the home page.
a thousand sf of radiant slab will store about 100k btu if you accept a 10 degree daily swing in temperature, from 65 to 75; slab temp 75 to 85 (with 85 being as hot as you'd want a radiant floor.)
The good news is that you shouldn't need a whole lot of heat with DSW construction. The bad news is that you have cut wood, split it and haul it, and you can't travel farther from home than reload interval permits. Water storage would allow you to add solar hot water and a heat pump. |

Here is a second question...
Lets say that I currently had a HOT AIR duct system in my home thats hooked to a cold climate heat pump. Is it possible somehow to get the hot air from a tradition wood stove in the basement into the main duct of the heating system? |

That was exactly the way that mine was connected!! See below:
Years ago (1984) I lived in a 1,200 sq. ft., poorly insulated home in Pocatello, ID that had an oil furnace in the basement plus, sitting next to it, was a wood furnace which was about 15" wide, 26" long, and 18" high and was mounted on legs about 15" high from the floor.

The duct then ran to the outlet duct of the oil furnace. The stove pipe exited the rear of the furnace. The only time that I ever used the oil in the winter would be if I were going to be gone for more than a day. As I recall, a cord or two of dry fir would last all winter.

Add-on forced air wood furnaces are readily available http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_1036726_1036726
But again, go to hearth.com for tips on buying them and using them. You want a stove on the smallish side so they don't idle a lot, or conversely, drive everyone out of the house. If you don't know what your design heat loss is, that would be the first step. |
