Chinook 30 not heating the house

Great point and, this should have been mentioned much earlier.

Uhm...

How high are the ceilings? 15 ft? (22 ft pipe)
Does all the heat pool near the ceiling (as physics dictates)?
If so, a ceiling fan may help (in the setting where it does not "blow downwards", but blows upwards; the warm air will then glide along the ceiling and then to the walls where it'll go down to replace the air being sucked up in the middle. This avoids sitting in the stream of air under a fan that blows down, which will lead one to feel colder than needs to be. (I know this does not negate your 59 F measurement, but it's useful nonetheless.)

Credit where credit is due. So much reading and so many threads. Somehow I missed this or plain dumb forgot.

My apology, my friend.

Sure, I'm not disagreeing with your point. But "not enough wood" should be well within the grasp of anyone who's heated any house with any stove. This isn't exactly quantum physics.

I guess we will see! If this turns out to be the problem, someone'd better take away the neighbor's matches.

I'm thinking it's also how or when the question was asked. The OP could say to the nice and well meaning neighbor, "look at this full stove, I keep it full and I'm cold". The stove is actually 75% full of coals with three fresh splits on top. The neighbor that is keeping his house warm like everybody else with full cycles sees a full stove and says, "that's what I do too". Regular stove people would just say that if the bypass is closed and the stove full of wood looking stuff and the thermostat is on high that you're doing all you can do and there's nothing to fix.

Hearth members would consider fuel quality, flue construction, clogged cap, obstructed OAK intake, top off loading frequency, coal accumulation, etc.

I can tell you from experience that when you're asking too much of a stove and coals start to fill the firebox that output falls way way off. Flue temps drop, active flame drops, even with good quality fuel. People have been known to shovel out piles of red coals in order to fit new fresh fuel in and get that raging heat output that comes with the early stages of wood combustion.

Yes, wonderful, wonderful, off gassing.

I just stumbled across this thread and sorry, I haven't read it all.

It looks to me like the Chinook has a double-wall. I've got the older Princess, and it had removeable panels on the sides. I removed (or never installed) them. I don't know if that's possible with the Chinook or not. I have a feeling my Princess might not heat the house so well with the side panels installed, UNLESS I added the fan kit. Just a thought ...

I have the princess with side shields installed. The heat doesn't go away, it just is emitted to the room as hot air instead of radiant heat when side shields are installed. That's why stove efficiency is so high on the princess model, it delivers those btu to the room instead of up the stack.

Like that one guy that claimed the interior wall shields would make the stove inefficient. It just converts the heat from radiation to convection.

Did OP ever update after adding stack?

Yeah, that all makes sense. I guess I just like the radiant heat - we both sit within 10ft of the stove. I'd kinda like to get a Chinook, but this gives me pause.

Are you saying the side shields increase efficiency? I thought radiant heat was more efficient than convection heat? Anyways it would be nice to have the option of removable shielding.

 

[BKVP]

Guys,

You must realize all safety clearances were established with the side shields attached on the current models. We also educate dealers that anyone purchasing a Chinook or Ashford should definitely get the optional fans to help move hot air further into the room and home. While both a superb at shoulder season heating w/o blowers, once it get cold, most users benefit from having the blowers running.

It's not, a BTU is a BTU. It feels different to humans, but that's about it. And there's still plenty of IR radiation coming off the front of the stove.
I live in a warm climate, and we rarely need to run the fan, the Chinook is more than adequate to provide sufficient heat.
And I like the safety aspect, the firebox is not exposed to the outside, so it's pretty difficult to burn yourself touching the running stove (except for the door, of course).

No, just that having the side shields does not make the stove less efficient. The heat still makes it out as is reflected by the very high efficiency numbers on these BK stoves. We know the heat isn’t going up the chimney so it’s making it out despite the side shields.

Plus, as we know, with the BK design the stove body is the fuel tank. The cat makes such a large part of the heat on the normal low burn rate that the open stove top and front do a great job. Apparently, as reflected by the efficiency numbers.

Yeah but the heat transfer efficiency has to be greater with an unshielded stove? Doesn’t the shielding somewhat insulate the stove and send more heat up the chimney? Unless there’s a blower attached as BKVP states above to move more air? I wonder how this is all figured out when tested?

The current test method (FRM (Federal Reference Method)) M28R requires what is know as the fan confirmation method. The emissions results from this run are NOT part of the emissions grade. Instead, it is used to verify burn rates.

Incidentally, the new test method coming in 2027 is the IDC (Integrated Duty Cycle) and EPA is reviewing method and data now to make it an FRM for 2028, or very soon after. This method requires that if fans are an option or included, they must be on during all testing.

That would be reflected by lower efficiency numbers and the BK has(had) the highest efficiency numbers of any stove. Can't hardly lose any less heat up the stack while still keeping the fire alive.

Maybe instead of efficiency you might be thinking of the stove with heatshields losing maximum output capacity.

 

[RustyShackleford]

Are the heat shields on the Chinook removeable ? With the obvious caveat that the clearances are greatly increased. If so, does the stove look reasonably decent in that configuration ?
