Hi guys the wife and I are in the planning stage of building a house. I think I would like to have a water furnace its cheap heat I've got the 30 acres of woods.

So does anyone have a furnace like this or any other type? Whats good or bad about them? Heres what I've found its close to home and sounds good but....OPINONS please .http://www.nextlevelsolutionz.com/index.html

I'm thinking the 165 series would be good .The house is going to be 2000 sq ft.I would like to heat the hot water with also during the winter at least.Thanks TJ
 
There are some in my area. The ones that are in neighborhoods are causing some problems because of the smoke output. People who have them say they are great but the major problem is they are thought to polute. Towns here have for the most part either stopped giving permits or strictly regulating the use of them.
I am a fan of them and would put one in in a hertbeat.
 
Joe M. summed it up pretty well. There is supposed to be legislation in the works in at least 2 N.E. States to regulate these outdoor furnaces. Most reputable dealers will either make you aware of it or wont sell you one. But I see you live in the free part of the U.S. so you might not have any problems. Frank
 
They dont burn hot enough, so the release a LOT of particulate. I have seen a few around here and on a still morning they can fill a whole field with smoke. I think some have forced air blowers and can only assume they would work much better and burn hotter.
 
The problem is that they are outside and people tend to overload them so they make fewer trips out side. As with any solid fueled furnace you want to run small hot fires for cleanest smoke emissions. Wood stoves with the air inlet choked down boil water and various gases that become condense on the chimney walls, (creosote deposits). You will see brown stains of the stacks of many outside furnaces. If fed less at a time , more often this creosote would burn and or be hot enough as not to condense. Most outside furnaces I know of have a blower that is called into play when there is a heat demand in the house or the water temperature falls below a certain set point.
I burn wood exclusively in one of my houses so don't think I am playing tree hugger on this. This is the beauty of pellet stoves they keep a small hot fire all the time and with a hopper need be fueled upon occasion. Because of this they are very efficient and have a relative small environmental impact. Years ago with coal a stoker worked in a similar way. You fed rice or pea coal into a hopper. When there was a call for heat a worm pushed coal into the bottom of a bowl located in the center of the boiler. A fan provided forced draft for a hot fire. When the heat demand was met the worm was turned off as well as the air blower. The fire continued but a a much reduced rate. With the next charge of coal the burnt coal or ash was pushed over the edge of the bowl. Two endless chains of buckets elevated the ash from the fire pit and deposited it into steel cans with a round hole in the cover. The ash dump had a canvas hose that sealed the ash cans that you didn't have the dust all over the house
 
Lots of them around here as well. I would have one as well, but the wife said she wasnt interested in going out and filing it when i was at work. One other thing you may want to consider is laying pipe in workshop/garage, so you can heat it ambiently....... That was part of my plan.
 
I've done some more looking and found this comparison between the shaver model 165
Which has a water tank of 170 gallons 165000 btu up to 4000 sq ft and the fire box is .400 thick .

The hardy H4 has a water tank of 130 gallons 180000 btu the fire box is 14-16 ga stainless steel.

How can you have 15000 more btu with 40 gallons less water unless you are loading wood all day long to keep tyhe fire hot as blue blazes??

Also can someone tell me how much the difference between .400 thick compared to 14-16 ga steel.
 
There are a number of outdoor wood furnaces in this area of Missouri. One neighbor, outside of town, just purchased one. In this area wood is a common heat source. Son uses an indoor wood furnace as his primary heat source. Son uses a high efficiency propane furnace as the backup. Due to son's work schedule there are times when he is not able to tend the wood furnace.

Cost wise wood heat is inexpensive if you do not consider the value of your time/labor or equipment expenses.

At one time the city was thinking about limiting their use or not permitting any more wood burning appliances within the city limits. My gut feeling is that there will be more and more local or state legislation limiting or reducing wood as a heat source.

There's a difference between producing heat and storing it that should be accounted for.

Is one fire box really more than 3/8" (.375") thick? Stainless or mild steel?

I am no expert by anymeans, but I have learned a few things over the last 5 decades. Wood furnaces are the best form of appliance to heat a home - period. I grew up with Natural Gas forced air in town, wood at my grandparents and the choice is obvious. Celluloid fibre over fossil fuels any day of the week.

Any smoke from a wood furnace that is properly set up and cleaned regularly should not cause any environmental concerns. Remember the main by-product of burning wood aside from steam is CO2 which is what trees need to breathe. Trees breathe CO2 and expell O2 which humans need to breathe to live. It is a symbiotic relationship. Anyone who says a wood stove is environmentally dangerous needs to go back to school.

However, as much as I am an avid proponent of wood heat, I agree with Nik and the others on these outdoor stove thingys. The mill next door actually uses one to heat their debarker shed. It is useless.. does not burn wood efficiently, does produce an awful lot of smoke, does not burn hot enough so there is ash that also floats around.. Provides very little effective heat compared to the negatives.

On the whole that is still not a problem as any forest fire which is a natural occurrance and a desireable one for mother nature has varying temps as well. Particulate matter is great for the soil, but bad for lungs... oh well always a flip side.

Anyways.. to the point. Since you are going to new construction, you may want to consider a traditional forced air wood furnace. If you build to accomodate wood storage.. (I incorporated a 14x12 foot wood room where I can store over 10 cords - ceilings are 10 foot - so if I fill to the max I have almost 12 cords into my building plan as well as my cold room) plan for ash removal via an outside door at grade it can be a pretty impressive system.

Kerr produces a number of Wood Funaces that can be stand alones or used in combination with other sources of heat. I used to have my Scotty II / Scotty SSpaired up with a Propane fired forced air furnace. Now that has been replaced and the Scotty is paired up with an electric forced air furnace. These side mounted units primarily provide the air distribution and filtration for the Scotty. Oh, my house is basically a tri-level with about 3200 square feet of living space. The Scotty II heats it pretty well even in our extreme cold and I usually burn between 4-6 cords of mixed soft/hard wood over the course of our 6-7 month heating cycle.

My father-in-law has for years used a Kerr Scotsman. This is a 140,000 BTU wood forced air furnace and has had a hot water plumbing system installed in it way back when he got it. So, he has both forced air and essentially hot water radiators. It used to provide all the hot water for the house as well. He now uses an electric backup water heater for the summer months which replaced the old oil fired water heater he used for the summer.

You may want to investigate a forced air or even a water radiator system fueld by a wood furnace as a viable alternative. It will provide good moist heat, make use of you dead wood on your wood lot, provide soil ammendments (ash), give back to the environment in a friendly hug a tree manner and will certainly save you money in the pocket book. I heat my house for about $200.00Cdn maximum a year.

Yes, in case y'all missed that... how many of you can heat your home for $200.00/year or less. Some years it only costs me about $50.00 -- fuel for the saw table and Ellie :!: and provides me with an immense amount of fun, excercise which my heart appreciates and I get seat time to boot :wink: 8) :lol:

Oh I also use a Sentinel or a GSW 2000 equivalent double wall insulated stainless steel chimney, housed inside a surround to regulate the flue temperature.. Normally I no longer have chimney fires, like we used to before we put up the surround. The cause was temperature fluctuations over the 35 feet of chimney. Now with the surround, the temps remain almost equal all the way up to the top of the chimney as the cold air does not play havoc with the stainless.
 
Thanks guys for the input. Anybody got anymore??

George ,The stainless firebox is 14-16 ga The .400 thick firebox is mild steel.
 
Hey T.J. Have you & your wife considered a geothermal heat/air cond. system? These can be a closed loop system drilled vertically into the ground, or, if you have access to a lake (as we do) you can run a closed loop lake loop system.

We heat & cool a 4000 sq. ft. home here in Tennessee for about an average monthly electric bill of $135.00. :wink:
 
The only thing I can add is to be sure to talk to some satisfied users of this model in your area. One brand is very common around here, and the only ones that seem to burn fairly clean are those that are used to the max. Don't make the mistake of thinking bigger is better. Just my two cents worth.

I've not thought about a geothermal unit but ...I did do a google serach and found out how they work and what they do but couldn't find prices anywhere??

What kind do you have ? maybe i could at least get a idea.
