Why Buy a Nature’s Comfort Furnace?

We are taken back by
Nature’s Comfort high quality.

Built by the Amish; skilled craftsmen!

In the heart of Amish country,
with their strong work ethic
and pride in the quality of their work.

We all know about the quality of their hand built furniture; it is second to none. 

The quality of their outdoor wood burning furnace is also the same;
second to none!

You can have great confidence in their customer service and the work ethic
of the whole company,
led by Dave Nyhof, who leads by example.

(Like any major appliance, unlike some manufacturer’s furnaces, the Nature’s Comfort comes pre-wired and ready to install.

It comes with a pump installed
(which most manufacturers do not even supply; sort of like selling a car without a
steering wheel because you need one!)
and this is a heavy duty, three speed high-volume pump,
not a cheap smaller pump.

It also has a mechanical thermostat and an analog thermometer plus a water level indicator on the roof to show you when the water level is low. All of these furnaces (except for the NCB-80), allow you to heat up to four zones (buildings, structures, pools or hot tubs, etc.), at any time.

The Nature’s Comfort furnace has a forced air induction fan is on the back of the outdoor wood furnace, that is very large (250 CFM) with an air flow adjustment automatic damper (instead of on the front door, like many other models) and is the new automatic forced-air induction type, to fuel the fire with oxygen. This means that you WILL save wood but it does not mean that it has circuit boards or is complicated; it simply has a solenoid to open and close the air intake door, which makes it extremely more efficient (burns less wood), instead of a manual door that constantly needs adjusting.

None of our traditional, simple furnaces has any circuit boards, computerized parts, Smart Phone hook-up or anything complicated. 

All of our stoves have off-the-shelf parts that are easy to find and install; making this furnace easy to maintain and repair!

The firebox door is a real nice, big size; the smallest is just shy of 27 inches wide and 18-26 inches tall.

One tremendously valuable feature about this furnace is that it has a removable ash pan; meaning that you can clean out the ashes at any point in time. You do not have to open the firebox door and kill your fire like with other furnaces. It does not matter if the firebox is 800 degrees or 2000 degrees! No need to kill the fire!

It’s ash receptacle is 39 inches deep, that is an actual pull out pan, for easy ash removal; even when there is a raging fire up top! No need to kill the fire and then have to restart it; in the dead of winter!)


5/30/11: IN, NH, NY, MD, PA, OR, WA and VT no longer permit outdoor wood burning furnaces, that are not EPA approved.  
However, we do have a new EPA certified furnace available now! 

OR  you may be able to take advantage of the
less expensive ($2000+ less) and simpler furnaces that can burn COAL and
are built without electronics and circuit boards!
Check with your local code enforcement office!

You may be able to purchase a coal furnace that does not have to be EPA approved. As far as we can tell, they are okay in PA, IN, NY and VT and may be good in many other states too!

When it comes to outdoor wood furnace Indiana, TheThermoWind may be allowed in Indiana and other states because their restrictions seem to be on “boilers”, which the ThermoWind, is not.

Out largest outdoor wood furnace is over 300,000 BTUs
which many laws exclude,
as well and would be legal.
