The Federal EPA laws restrict Outdoor Wood BOILERS - and this is not a BOILER!

Please check with YOUR state before buying .
NOT permitted in NY state for heating a residence. 

Some states have their own state EPA laws but again;
most all talk about BOILERS and this is NOT a boiler!

The Forced-air models use ductwork and a full-size 2010 CFM furnace fan,
instead of a pump as on a boiler, to simply blow hot air into your home,
into your existing ductwork BUT we can show you what to do it you don't have ANY ductwork!

Comes complete with a 75 CFM forced-air draft fan with an automatic damper to fuel your fire with oxygen, plus a big, full-size furnace squirrel cage fan (3-speed 2010 CFM)

- IDEAL for any home or shop without an existing heating system!

No furnace? No ductwork? No radiators? No boiler? No problem!!

- Excellent for those people with cabins or homes that are left unattended because the water won't freeze; there IS NO WATER.

- Use our huge over-sized built-in furnace fan instead of an air handler or using your current furnace fan!

- Before spending thousands of dollars on a new furnace for your garage or shop, plus many more thousands for fuel - choose a Hyprotherm FLFA Hot Forced Air Model and you can heat for Virtually FREE!

- Eliminate the threat of a fire, by having the furnace away from the house, just like with our outdoor wood fired WATER furnace (often called a "boiler".

- Do you want an indoor wood burning furnace in your attic or basement? Try our outdoor wood burning furnace instead.

- No carrying wood into the house, along with the bugs, bark and trash.

- NO SMOKE escaping into the house from the firebox door either!

- Hook up our outside wood fired furnace to your central heating ductwork!

Ductwork is needed to distribute the heat, so an electric, gas, oil or propane furnace, etc, and heat pump or geothermal system can be used.

Your existing blower is not used because we have one on the Thermowind  FLFA that is likely even bigger!

No boilers or radiant floor heating systems can be hooked up with the Forced Hot Air Thermowind.

Remember, you can add ductwork to any building (or not even use any ductwork) to heat any building.

We can even help you if you don't have any heating system now!
