Fisher Wood Stoves - wood-stove.org/

Fisher Stoves - woodstovewizard.com/

Bob Fisher had some basic criteria that he wanted from his stove, and his wife supplied some of her own:

  • It had to be an airtight wood stove
  • Ventilation needed to be restricted and controlable with vents
  • It had to be able to keep a fire in over night
  • Carol wanted to be able to cook on the top of the stove
  • The stove couldn't smoke when the door was opened
  • The Fisher Stove had to last - this called for heavy duty steel and firebrick

EnSage Media youtube Starting a Fire in My Jotul F3 Stove using a Campmor Catalog!


This heater is highly efficient which make this stove very attractive. Most people who buy this wood-burning stove enjoy it and keep it for ridiculously long periods of time. The wood burns on a bed of ash, rather than having some sort of grate. This has been said to be the best way of burning wood in a stove. A built-in, yet extremely effective airwash system keeps the large windows clean and free of condensation, allowing you to enjoy the large view of the fire.

Fisher Grandpa model. 20” log.

PAPA model. It takes a 28” log.

our old camper school bus has a BABY Bear in it.

Here is some of the Fisher Story at hearth.com/econtent/


For our great room, have a Defiant Vermont Castings, with catalytic converter…Heats well, and wood lasts a long time.


I have an Earth Stove by Colony Hearth in my house. It heats great.


We have had two Timberlines over the years - very similar to the Fishers, they were the cream of the crop back in the ’70s. We replaced it with a Hearthstone soapstone last year - took some getting used to learning how to fire it but it sure is nice to have a warm stove when you get up in the morning.


Ran an Earthstove for a few years and thought it was comparable to a Fisher.

Been using a Vermont Castings Defiant Encore for the last 17 years. The top loading and ash pan clean out make it a very easy to operate stove. Heat output is second to none. The catalytic converter is a gimmick meant to please the EPA and the greenies.


I have used Ashley and Wondercoal with very good results. Got to get a coal stove or get a catalyis(sp) converter. Not the prettiest stoves on the market but they are affordible and efficient. Speaking of efficient I don’t buy wood, I can’r burn 1/5 of the leavings from the mill. Might be different if I was buying firewood.


I have a Jotul Oslo F500 Firelight. My friends own a hardware store and specialize in BBQs and Fireplaces. Their opinion after going to all the trade shows and looking at all the stoves is that the Jotul has the best looking flame. I love to watch the flames as it looks like the flame is pouring up out of the wood. It is a not catalitic stove. If you burn too hot you can damage the catalitic insert and they need to be replaced periodically. They recommended the Jotul and I have not been dissapointed. They are a swedish stove and have a very nicely detailed casting so they look good even when you’re not burning anything. I heat my 2000 sq ft home all winter alomost exclusively with the stove.


That stove was just replaced a month ago with a Jotul Oslo. I really like the Jotul stove it has one moving part, the draft control. Although it was not a factor when looking at stoves the viewing window in the front of the stove makes you want to sit, relax, and enjoy the view. I looked at the new Lopi cast iron stove but the fact that the castings were made in China was the main reason for going with the Jotul.

I have a Woodstock Soapstone stove. I’ve had it for about 25 years. It has a cast metal frame, and 1” of soapstone on the sides and top. It will keep heat all night. It doesn’t use a great deal of wood.

Morso are famous in Europe and I know they sell in the USA and Canada, they are a high quality cast iron stove manufacturer. Jotul are brilliant and I have toured their factory in Norway, I could post some photos if you like? Our f118 nearly heats all the home and never needs rekindled. I ve owned many stoves and i think jotul and morso are the best, maybe jotul has the edge, slightly, just my own view. Willy Campbell is a star, I m sure I m related to him !

Woodstove Chimney Pipe :: Through the Wall


Great article on safe Chimney pipe design.

firewoodhoardersclub.com/forums/threads Replacing Fireview with....?

Lot’s of good information in this thread.

Mentioned in response

        Ideal Steel
        Blaze King King
        Regency 5100

Well, I think first of all, if absolute heat output is a prime concern, then a stove with a larger firebox would serve best. Of the stoves you mention, the Blaze King, King model (they also make a Princess but it is considerably smaller) has the largest firebox and will simply hold more firewood and so deliver more heat per full load. It seems to be a very nice stove and was on my short list three years ago when I was in the market.

I ended up buying an Ideal Steel, it has served very well and I am very pleased with it. The Progress hybrid was also on my short list.

A couple of points you may want to consider: A front opening door is much easier to clean the glass. A side opening door is usually easier to fill and will result in less smoke spillage into the house. This is only a consideration for the Progress hybrid as it is the only side loading door stove on your list. It is also a medium size stove, and the smallest on your list.

The Blaze King King has a huge firebox, is a catalytic based stove and has a huge base of very satisfied customers. No question in my mind that it would provide the most heat per load (such as for overnight) of the stoves you list, plus it has an automatic damper which apparently works quite well. A couple of downsides are: 1) it requires an 8" chimney (flue). They used to list a 6" flue as an option but that seems to have been removed. My suggestion would be to call them if you are planning on using that stove on a 6" chimney. 2) it does not have a grate and so requires ashes be shoveled out, or a plug removed and the ashes shifted through that hole when the stove is mostly empty. A grate in a stove with a sealed ashpan (Ideal Steel or Progress for example) is easier to clean the ash out of it while it is actually running. 3) the combustors are expensive for a B.K.K. at ~$375 or so. Blaze King will claim up to 10 years for combustor life buy my experience is more like 2 years or so and so the cost of the combustor you will need for any stove you are considering becomes important over, say, 10 years or more of owning and using the stove. 4) the Blaze King King is a little more difficult to remove the combustor for occasional cleaning while an Ideal Steel, for example, allows the combustor to be removed in a matter of seconds with no tool whatsoever. 5) If running very low and slow, I think the Ideal Steel is the best design to run cleanly because the combustor is located directly over the top / center of the firebox and so is easier to keep 'lit'.

There is one other stove that I considered carefully, and it is a very direct competitor (IMO) to a Blaze King King; that stove is the Regency 5100 It also has a huge firebox, about the same as a B.K.K., is combustor based but is also a hybrid stove with a secondary burn ability. A very nice looking stove, very well made, from a company with an outstanding reputation and a limited lifetime warranty (!!). I suggest you check one of those out as well; I have seen one in person at a local dealer and in some ways like it better than the B.K.K. although it does not have the automatic draft feature of the Blaze King.

In the end, I would suggest considering what you really need out of a stove and try to solve that problem (or those problems) directly. You specifically mention your wife is cold, you want more heat out of a stove and long burn times so again, a big firebox is what will deliver there. There is no magic method by which a small to medium stove can possibly compete with a large firebox. My own choice would be for a cat. based or hybrid type of stove, which is all that you mention in your list. As I read your post, I tend to think the B.K.K. would best serve you and your family, especially during those very cold Minnesnowta winters. :) I live in the northeast and while we have 'real' winters, they are not nearly as cold as I think yours will be and that extra cubic foot of firebox will almost certainly have a great value. Especially so if you do not have ready and easy access to long burning hardwoods.

I use these probes: New 3 Meter High Temperature -100~1250 C Thermocouple K type 100mm Probe Sensor | eBay They are 8 mm on the threaded section so the hole for the thermometer on the IS must be drilled out and tapped (Oy Vei- my probe is too big for the hole! (Easy Boys)) to accept it. Note that these do not have standard K- type ends so you will have to buy some of those too and screw the wires to the adapters, not a big deal and the adapters are inexpensive.

Then I use one of these to read the thermocouples: 4 Channel K Type Digital Thermocouple Thermometer Measurer SD Logger Generic | eBay They are nice because they are 4 channel and record data on SD cards. This can be useful is you want to see how different settings affect an overnight burn for example- you can see the temperature of the cat., firebox, stove top and flue gas all at once for hours, days or even weeks at one time. I think it is what allows us to get the most out of a stove.

Thank you, Brian. That’s the information I was looking for and just couldn’t seem to find.

These are the type of connector I would need for those probes, correct?

DuraVent DVL double wall stove pipe

DuraVent DVL Product Page

DuraVent DVL 2016 Catalog

DVL’s double-wall, air-insulated design reduces clearances to combustibles from 18” to 6”, the closest clearance to a wall of any connector pipe. DVL improves stove performance by maintaining high flue gas temperatures for a strong, steady draft. Because the inner wall is stainless steel the flue heats up faster, stays hot longer, minimizes the formation of creosote, and has the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting or crimping.

Applications - Double-wall interior stovepipe for connecting wood stoves to manufactured chimney.

Materials and Construction

        .016" stainless steel inner wall.
        .018" galvanized outer, painted black.

Clearances - 6” clearance to walls. 8” clearance to ceilings, including cathedral ceilings.

Diameters - 6”-8”

Listings - c-UL-us listed to ULC S641 (MH14089).

Hearth Pad



With stoves burning cleaner and hotter than ever before, a traditional ember protector or homemade hearth may not protect the combustible floor beneath your stove. Building codes and safety standards now require the hearth pad to provide adequate protection based on the stove model. With that in mind, we now offer two levels of protection to meet the needs of every stove. All our pads are tested to meet or exceed UL1618. Whether you’re burning gas, pellets, corn, coal, oil or wood, our hearth pads offer the best protection on the market - and they look great too.

Thermal Protection

For today’s highly efficient stoves, a Hearth Classics non-combustible ThermaShield pad will block the heat from passing through to your sub floor. Fully non-combustible, with an R-value of 1.61, it provides the greatest protection of any manufactured hearth pad. For stoves requiring an R-value higher than R=1.61, a ThermaShield Low-Profile base, a ThermaShield Pedestal, or a ThermaShield Xtreme Pedestal can increase the protection up to R=10. All our pads are tested to meet or exceed UL1618.

How thick are your hearth pads? Tiled pads are 1¼” thick. Stone and Brick pads are 1½” thick.

hearth.com/talk/threads post by Hogwildz Micore + Durock Strategies?

I used 1/2” micore & 1/4 Durok and has no issues. Make sure you use the screws required for cement board, and be be generous with them. I think I used them every 6” to 8” apart. And 6’ along the edges. I have had no issues with the microre compressing or such. I put 1/2” x 18” square natural slate on mine.

hearth.com/talk/threads/ HELP ! - Hearth build


An alternative is to use higher R value Durock which is R=.39 for 1/2”. 3 layers will easily exceed the required hearth R-value. Use of latex modified thinset is fine and recommended.


The last 2 tile jobs I have used Hardibacker over Durock as a personal preference, including my current hearth and stove install which I also used slate tile.


It will work when ember protection only is needed, though not my preference. Hardibacker is R=.26 vs Durock NexGen at R=.39.

Skip the in between layers of hardibacker. Instead start with a 1/2” plywood bottom, then 1” micore, the 1/2” Durock.

Help with research on stove selection

Tue Jan 9 11:27:29 MST 2018

My wife and I recently moved to a small town and into a 1 1/2 story home built in 1914. The lot is about 1 acre so there is space to process and stack firewood. There is a non working pellet stove in place, but I see no evidence of a previous wood stove.

There are a number of issues for me to research before we purchase and install a wood stove. I’d like to get advice on stoves for us to consider.

I am looking for a new hybrid stove with a fire box about 3 cu. ft. The current short list is Woodstock Ideal Steel, Regency F3500, Hearthstone Manchester

I prefer the Ideal Steel. My wife likes the look of the Hearthstone Manchester, but the Ideal Steal not so much. She really likes the sculpted cast iron look in black.

I’m making my best case for a undecorated black IS but would like help in getting a list of stoves to consider and in particular what stoves might look attractive to my wife and have the efficiency and ease of maintenance I’m looking for.
