Hearthstone is getting real

Depends on wood, my house is hard to judge because I heat 2500 sq. Feet with many vaulted ceilings over 5 floors. I can keep STT on sugar maple over 500 for 8 hours. For reference.
My oil backup heat thermostats are set to 50 I live with women so that doesn’t work..

if -10 below or colder I reload ever 8 hours warmer every 12

 

I would say those are good times in those temps.When it gets single digits or below zero here I'm running both stoves.The One gives me 14 hrs of usable heat and I can live with that.The Mansfield will give me 8hrs.

 

For us this shoulder season has been a PITA. March and April have been mixed with cold rain, odd snow, and most mornings in the 20's-low 30's.
When it's sunny, a south facing warms us up fine. But at zero dark hundred it can be in the 50's.
So unlike winter with 24/7 fires, this shoulder time is many startup PITA fires. Going through newspapers ( librarys' sources closed for the NYT and WSJ ), and much kindling sometimes 2x/day since
Ms. SWMBO likes to be hot. I do not have rank anymore.

P.S. Any here ever use C4 for heating rations or starting fires ?

 

I just use a propane blow torch. $4 tank lasts a whole season.

 

So Rich, how are they doing this? More than double the burn time?

I'm looking at the ManCHESTER, not Mansfield, but the old Manchester lists a 14 hour burn time, the new "Manchester TruHybrid™ 20/20 Certified" (and they're the same size), lists a 30 hour burn time. I'm with you - this is a huge deal, if it isn't just a gimmick. Maybe you or someone will have insights on my question.

Yes, these are stated as BURN TIMES, not "Heatlife™" (both) are listed on page 62 of the main Hearthstone Stoves product catalog.

 

I think they're attributing these long burns times like everybody else to the catalytic converters.Isn't the manchester smaller than the Mansfield.If so and it doesn't have a Cat.forget 14 hr burn times My One doesn't burn for 14 hrs but with the burn time and the heat off the stone I'm getting 14 hrs of good heat.Of course the pipe damper also helps.On the new line of stoves someone else will have to bring the insights.I won't by one until I hear some real time experiences.Even then I may stay where I am.

These guys test a fully loaded Green Mountain 60 which has the same TruHybrid system, 2.0 cubic feet and they show a STT of 200 after 19 hours

Booya. Once you have this level of performance you will wonder why you waited so long Im glad Hearthstone actually has a design that truly appears to compete with the other 2 well recognized cat stove manufacturers. Need a few guys/gals here to make the leap and get FHC some real feedback!

 

Love those ad writers' wondrous naming " TruHybrid", "FlexBurn", "V3".
Where are the focus group real world users of the new and improved products ? Where ?
Like it was said here, who wants to be a test dummy.
".......I will love you in the morning."

 

The GM product has a real world review by a satisfied BK owner that has been going on this winter. His thoughts are all very positive. As far as test dummies go!

 

"GM product" ? BK owner drives a Chevy ? ??

 

A 200 degree stove after 19 hours. Not terrible for 2.0 cubic feet but 200 is not what most folks consider burning and the fire has certainly gone out. I wonder how long the cat was active which means burning which happens at exhaust temps of 500 and up.

Hearthstone used to have cats. They are not totally new to this.

 

I agree with Highbeam
1. 200* is not heating much
2. CATs stop throwing heat at 500*. When new and with dry wood
I just went and checked my IS is still 138* from fire loaded Wednesday night it’s Friday. Is it heating now. I would say no. Could I re light without a match yes. Loaded with mostly red maple.
Would I claim this as a 43 hour burn time?

I wouldn’t

 

That old Manchester is smaller than the Mansfield.The burn time they quoted is so inflated.The bigger Mansfield won't give you a 12 hr.burn time even on it's best day and I doubt the Manchester will either.Since these guys inflate the burn times nothing they state can be trusted.

 

Yea they list the Clydesdale at 12 hours and I pack it to the gills and am always below 200 degrees after 7 hours.

 

Many sellers inflate the burn times.The Hearthstone One is the only stove that I found that comes close to the heat life specs.Everything else that doesn't have a Cat.is a risk with many falling far below what's advertised.I do squeeze more time out of the Mansfield when I'm down to coals and I leave the door open.This works well.I just put a screen in front of the opening to catch any popping coals.

 

We do know that there are lots of different definitions of burn time. Manufacturers usually use the most liberal one to pump their product. Okay. What we should be able to assume is that whatever the old Manchester could do for burn time, the new Manchester can go twice as long.

There’s no free lunch. If your home needs 5 cubic feet of fuel per day to stay warm then you’re still reloading twice per day. That’s okay though because you can set the stove to burn constantly for 12 hours vs. a big surge of heat for three hours and then a long 9 hour cooling period. Way more comfort with a constant heat in my experience.

 

Burned cat stoves ( pre "Flexburn" VC Encores ) for a couple of decades. Enjoyed long heat times.
BUTT the maintenance, extra burning steps, and fussiness of the stoves was why we went with Jotul non cats 2 years ago.
We drank the cool aid of the new VC company. Two Flexburns fire drills later with returns , we got reliable, proven non cat stoves.
Wood stock and Blaze King have both solved most of past problems with cats with Q.C., engineering, and post sale service.
Cats still have a life ( ~ 12K hours or 2-3 years for those of us using wood heat 24/7 and 99% BTUs with no central heat ). Air control is critical such as gaskets. Blaze King needed extra space behind the stoves for us.
And, Woodstocks she thinks are plain ugly. Can't beat both companies however for service.
No free lunch for any technology. YMWV.
Burn time specs are "I'll love you in the morning."

 

Ok, any number of folks here have mentioned that catalytic converters have a limited lifespan, especially for those of us who use wood 24/7. I'm attracted to longer burn times. In Western Oregon with mixed wood, mostly fir.

So what are the costs and difficulties in replacing these parts? End user do-able? Complicated? Expensive? It depends on...? Worth it? Please fire at will.
