Woodstock's next Hybrid: Version 3 (Franklin Hybrid?)

Wow, someone needs to go split some wood. I think everyone needs to take a deep breath and step away from the computer for a breather.

I think cabin fever is setting in well at least at my house I know it is just watch my kid......lol

 

Unpossible. There are no other forums.

 

Totally agree!

 

So I'm curious as to how they're making this new stove even more efficient than the Ideal Steel. Is the cat out of the bag on that one yet? They were tight lipped about that when I visited the factory and picked up my stove in the fall. BrianK, anything you can share on that front?

 

As far as I know, that info is just scuttlebutt rumorville so far. Someone may have had some inside info and it made it's way here but I don't know the source or if it's true.

 

Thanks Scotty. (My apologies, I've been under the weather and not as patient as I could have/should have been.)

 

This banter (aka neg crap towards Woodstock) bodes VERY well for Woodstock. That means they are doing really well and getting under some other companies skin.
Interesting......

 

Think this one will rear vent? Adjustable rear vent height? Need to stay under 27" to clear my lintel

 

First off, welcome aboard hamsey.
Next, here's a link about the new stove.......http://blog.woodstove.com/2015/02/hybrid-version-3.html
Lots of good info there, and Lorin is a member here. If you have specific questions that someone here can't answer, she might be able to divulge a secret or 2.
Looks like it'll be top or rear vent. Don't know if the legs will be adjustable like the IS for your lintel height, but with a side door, I doubt it.
How large is your opening, and will you be able to open the door if the stove is inside that opening?
Lots of questions.

 

If the basic firebox is anything like the WS IS it will probably rear vent. Not sure of what the betas look like yet or how many mods that took place since I saw it in October.
papadave had mentioned, you can e-mail or call Woodstock and they will answer any questions you may have. If you contact Lorin on this forum you may wait longer for a response than if you called them directly.

 

This thread and the bickering in it amuse me.

That aside, I am excited to see the direction hybrid technology stoves will move in over the coming years.

 

Me too; I think this is the first real step forward in residential wood burning in 30 years or more.

The two EPA type stoves available have always used one of two possible techniques: the secondary burn types, which will burn cleanly but only when putting out a lot of heat with the attending loss in efficiency (more heat up the smoke pipe) or the catalytic types, burn extremely cleanly, can be extremely efficient, but only at low to medium firing rates usually. The hybrid really does combine both of these technologies, allowing a single stove to be as efficient as possible across the entire output range and still allowing a very slow burn when that is desirable.

Another thing that is great to see is that some companies are really starting to address the efficient management of heat produced by the stove in the first place. Most stoves that have a cat. use a bypass method which basically dumps the hottest part of the stoves' output straight up the flue- not very efficient at heating the room the stove is in. Most stoves also place the combustor such that the exit is pointed again directly at the flue, again effectively dumping the very hottest part of the entire stove directly into the flue and 'overboard' rather than into the room. Lately, there is a move to change the gas path through the stove, even when in the bypass mode, and change the position and direction of the combustor to better aim the very high temperatures at the stove body rather than the flue; the result is getting quite a bit more of the heat generated by the fuel into the house, where it belongs IMO. The old ideas about having a relatively high chimney temperature to prevent creosote buildup just do not apply if the stove burns cleanly in the first place.

I am looking forward to what the stove designers come up with to increase efficient and make better wood stoves.

I agree 100%. I’m still burning a 35 five year old Sierra stove and this “new” hybrid technology is the first thing to come along that makes me think it’s time to upgrade.

I too am very interested in the new Franklin Hybrid. I followed all the Ideal Steel beta threads last winter, here and elsewhere, and even made a down payment on the IS. I put the IS order on hold when I heard about the Franklin because it sounds like it might be a better fit for my home, size wise. Everything I have read and the couple of conversations I’ve had with the people at WS have sold me on the company and the Hybrid stove technology. Now I just need to decide whether it going to be the Franklin or the IS. Hope to see some beta reports on the Franklin real soon to help me decide.

Welcome to the site! Good bunch here, likewise at Woodstock. You must be looking forward to burning more efficiently and using less wood.

 

Called Woodstock the other week when I was deciding on the PH or wait. I could not get any information about the dimensions on the 3. It would stick completely out of the fireplace so we can use the side door. PH is just too big for the room it would be in so I had to cancel it. From talking to WS it does not sound like the 3 will be ready until after the new year. Just worked out a deal of trading in my clydesdale for a heritage. Bummer would love to have a hybrid.

 

That sucks. Too bad you didn't get any of that to work out. A hybrid would have worked out well for you.

 

Smaller stoves tend to burn cleaner so thats a plus. Easier to maintain firebox temps in a smaller space. They can do tricks with how the air comes in and mixes in the firebox. One trick they used with the IS is the extra air that comes in at the combustor. As the main driving force of a stove is the draw of the flue. So you only have so much air coming in to a stove being sucked in by the draw of the flue. So if you open an inlet to put air in at the combustor up top of the fire box that makes the air coming in down at the fire level to be less as the suction of the flue is divided between the primary inlet ,the secondary inlet and the combustor air. So your not starving the combustor for oxygen but yet your slowing the fire down below. Hope that all makes sense.

Also inventing ways to make the heat have to to travel farther before exiting the stove lets more heat to radiate out into the room. The soap stone lining absorbs heat and stores it. Some stoves have fins inside the stove to increase heat transfer to the outer skin of the stove.

There are two types of efficiency's the clean of the burn and then the heat transfer out into the room efficiency. You can have a clean burn but if you dont radiate that out into the room you loose heat up the flue.

One aspect of these high efficiency stoves is that since you build up the heat in the fire box you can get a clean burn with very little air flow thru the stove. Now what does very little air flow mean? Well it means less heat flushed up the flue and more time for heat to be radiated out in the room. We all know that a stove can burn like crazy with the door cracked open but very little heat builds in the fire box as the air flow is so high all that extra burning the heat gets flush up the flue. You will see you stove pipe temp get higher than your stove top temp in that situation.

And lastly this all is helped by really good dry seasoned wood.
