ALL furnaces now come with a Motion Detector Light that comes on when you come close to the furnace at night.

No switches to mess with! No forgetting to turn it off!

All boilers and forced-air water-less furnaces have a chimney cap too (or alternatively) a chimney adapter to add 6″ flue pipe.


Carl is heating a massive older colonial home and LOVES IT!
Another customer, who is VERY HAPPY; he has an old (drafty) 1935 home
with single pane windows and very little insulation and loads it twice a day unless it is VERY cold – uses some hedge

2 foot door seal
HUGE 24″ x 24″ (2 foot x 2 foot) door with replaceable rope door seal
AND STAY-COOL handles!
Optional 1/2″ thick firebox! The thickest in the world!
Our standard firebox is 3/8″.
3/8″ is 50% thicker than most of the competition
and we have NEVER had a firebox failure!

This chimney design, along with the damper forced-air induction fan,
blowing oxygen in from below the grates (just like a blacksmith’s forge)
is what help us achieve over 75% efficiency!

The grate in wood models, including the Thermowind Water-Less models
is made out of super-thick 3/4 inch bar stock  or CAST IRON in coal models;

(Just a snippet shown here)
Shaker type is standard optional while flat cast-iron COAL grates are standard
on all front loader (except the 85 Econo)!
We have NEVER had either one burn through!

The air blows in from the back of the furnace!
There is a blower in back that feeds air into the firebox, below the grate, to feed oxygen to the fire.
Feeding the fire from the bottom (fires burn from the bottom up) is the best way to get complete combustion from the wood
– like a blacksmith’s forge! 
This is infinitely better than a fan on the front door blowing air into the side of the fire – or a manual draft.
The fan is thermostatically controlled to keep the water at a set temperature and is adjustable.

Old (Original) Legacy style
Old (Original) Legacy style
The new firebox is 25% bigger and has a 3/8″ water jacket bottom,
when you get the standard 3/8″ thick firebox
and HALF INCH THICK, then you get the 1/2″ thick water jacket bottom

This is about a 23 year old furnace (when I first put up this website).
The original house, sitting right beside the furnace burned down but the furnace (not responsible) was still operational.
They kept it right where it was for the next house and it’s still being used today!
