Summers Heat 3,000 Sq. Ft. Add-on Wood Furnace

Wood: 50-SHW35

It's no wonder we call this the “work horse” of our stove family. Our Add-On Furnace can hook into your home’s ductwork to supplement your existing heating system, or you can “dump” the heat directly into a workshop or other large area. The large, 850 cfm blower with thermostat pushes hot air through an 8 in. hot air outlet on the top of the stove, and if this hot air is routed into your home’s existing ductwork, it can heat up to 3,000 sq. ft.!

Also, we were the first to put a viewing glass on the door of our furnace, which means that you can check on your fire from the top of your stairs if the stove is in a basement, or from across the room if you place it in a large area. This furnace burns wood, and we’re talking about big wood: the 4.7 cu. ft. firebox accepts logs up to 25 in. long, and a huge ash pan below the firebox means that you will have ample room to collect the ash from those big logs! 

Now comes with brass and nickel handle sets, so that you can decide which look you like for your home.



  • Heats up to 3,000 sq. ft. when fed into your existing ductwork; supplements existing furnace
  • Reliable design provides for long life and more efficiency (Product is not EPA Certified)
  • Large 850 CFM blower aids in whole-house heat circulation


  • Cast iron doors and quality steel body promise years of durable service
  • Blower (and thermostat for blower) included for an added value of nearly $300
  • Brass and nickel handle set are both included – choose whichever look suits your home best


  • Accepts big logs – up to 25 in. long (in a 4.7 cu. ft. firebox), which means less log cutting than with smaller stoves
  • Extra-large ash drawer for easy ash removal
  • 6 in. top vent fits standard stove pipe and allows for easier installation
  • This was the first add-on wood furnace to include a standard viewing glass – check on your fire from across the room or the top of your stairs
  • 8 in. hot air outlet can feed into ductwork or dump into your room (great for heating a shop area, for example)

Quality and Charm:

  • Satin black steel body with cast doors and spiraled handles make this a practical addition to your home or shop
  • Cast iron door with door glass and air wash system offers a clear view of the fire
  • Meets UL and CSA standards for product safety
  • Proudly made in U.S.A. and supported by our own Technical Support staff
  • Trim package may vary by store.

We also have a 'Walk-Through' Troubleshooting Guide on this site...just go to the main FAQ page and choose 'Troubleshooting' under the Categories, and click Filter.

And, as always, you may contact a Technical Support specialist toll-free at (800) 245-6489 with any further questions.

How do I install the AC-1339 controller for my wood add-on furnace?

What about external thermostats for pellet stoves or wood furnaces?

A Note on our Add-On Wood Furnace: Do NOT use an external thermostat on our 28-3500/50-SHW35/50-TRW35 whole house add-on furnace. Follow the instructions in the manual pertaining to the controller that is included with our furnace, and contact us if you have any further questions.

Pellet Units:
There is now a Remote Thermostat that may be used on our pellet units.

It is actually easier to install than a wall thermostat, and can be installed in about 5 minutes!
Click Here to see the Remote Thermostat

External Wall Thermostat for Pellet (or Multi-Fuel) Stoves: When using an external wall thermostat with our pellet freestanding or insert models, do not place it more than 14’ (fourteen feet) from the stove.
An external thermostat (such as our Part No. PU-DTSTAT) can be used on our pellet units as long as it is a 24-volt that works with millivolt systems.

Instructions: After unplugging the stove, locate the jumper wire on the bottom of the control panel (J-3). The two screws should then be loosened and the jumper wire removed from the board. Next, the two thermostat lead wires should be connected at this location and the screws tightened; the jumper wire should be saved for future operation without a thermostat. More information can be found here.
The pellet stove will operate differently once the wall thermostat is installed -- see your owner's manual and contact us with any questions.

If you need more information on this, please call Technical Support at (800) 245-6489 or  email us.

Will a wood or pellet stove save me money? Is this for me?

We've all heard  many of the great reasons for purchasing a wood (or wood pellet) stove...

Wood and Pellet Stoves Save Money

We've all heard  many of the great reasons for purchasing a wood (or wood pellet) stove.

       A few of the more popular reasons are:
       -It uses renewable fuel
       -The fuel is widely available
       -It makes you more self-reliable and independent from oil, electricity, etc.
       -The heat just feels "better" and the flame is cozy and beautiful to look at

      But the main thing on many people's minds who are considering the purchase of a wood, pellet or multi-fuel stove is:
    "Will a wood stove, multi-fuel or pellet stove save me money?"

Please take a few moments to look below at some of the resources we've gathered that address the advantages of heating with wood or wood pellet fuel.  They cover many of the great perks of burning with wood and pellets, including the reasons listed above - and, yes, we've even included handy fuel calculators, so you can get an idea of how much money you can save. Enjoy!

Fuel Calculators

First things first...

The Hearth, Patio & Barbecue Association (HPBA) has put together a quick Fuel Efficiency Calculator that can give you an idea of how much money you may be able to save annually.  You can even enter your own costs, if you want to be more accurate.

Want to try some other calculators?

Pellet Fuels Institute has a nice Fuel Calculator chart here

And has a great Fuel Calculator of their own, here

But wait, there's more...

--We're always touting the fact that we have so many EPA Certified (and WA State approved) wood, pellet and multi-fuel stoves in our line-up. The question has been asked before: "What's so great about that?"
Well, less smoke and more efficiency means that, besides being great for the environment (and easier on your neighbors), it actually saves you even more money.
The EPA has some good information that answers the question:  "Will switching to an EPA Certified stove really save me money?"

--The HPBA also has a short overview of how to choose the right stove for your home, here

--To help you narrow your options and explore the benefits of our stoves even further, we've put together an article that goes into some detail describing how you can choose the best stove for your needs

--Mother Earth News has an article entitled "Is Wood Heating Right for You?"  It covers some of the benefits of heating with wood and helps you decide if it's really for you.
