So I just bought a used Coal Chubby Sr. on Craigs and I've started a total tear down to refurb the unit myself. Many thanks to I'm On Fire
for the great play-by-play on his rebuild here, http://nepacrossroads.com/about16683-165.html
. I'm currently waste deep in grinding and sanding the rust and paint off the unit, inside and out. I have new Mica and Gaskets in the mail from Larry (GREAT GUY!). I will post pics tonight hopefully. As for the Jotul 507:
I am hoping the Chubby will replace and outperform my Jotul 507. Don't get me wrong I LOVE
my 507, what a great stove! But, after burning all winter long on the 507 I noticed it had difficulty keeping up when the temp dropped below 25 or so. And, in MA this winter we saw a lot of 15 F at night. I have 1800 SQ ft and floor vents to get the heat upstairs. I think I just need a little more output, and from what I've read, the Chubby is the way to go.A couple questions to other Chubby owners:How low can you run your stove? What is your rate of consumption on the lowest setting?
I'm talking spring and fall settings. With the airtight Jotul I could close the intake down low and run at about 350 F for 12+ hours on 8-10 LB. As low as 0.75Lb/hr. This meant I didn't have to run the oil furnace at all, even in fall and spring 40 F temps outside.How hot do you typically run your stove? What is the typical surface temp? What is your typical rate of consumption?
One thing I love about my Jotul is that I can run it at at 450-500F for 10 hours while I'm at work on just 12LB of nut coal. That's about 1.25 LB/Hr. The Jotul 507 is just so efficient. I'm hoping the Chubby does not disappoint. I want a stove with more output, but I dont' want to eat up my cost savings over the price of oil. I'd probably burn coal anyway (addicted), but it's nice to feel like your saving money.How high do you run your stove on cold nights? What is your rate of consumption on a high setting?
The jotul is supposedly capable of running at 800+ degrees, though I never pushed it that high. Above 500 I could easily reach a point where the entire coal bed it glowing red and it started ripping through coal @ 2+ LB/hour. When the entire bed is burning red, I think you're no longer efficient. I felt like I was maxing out the stoves potential. Thus, my drive to find a stove with a little more throughput.
AS A SIDE NOTE: I still have my U.S. Army Cannon heater, but it's just too darn powerful for my house. The cannon heater on its lowest configuration would have my downstairs ambient air temps running at 110F, making the first floor uninhabitable. I'm hoping the Chubby has more control and won't overpower the house. The cannon heater is NOT airtight by any means. The chubby looks like it's pretty close to air tight.
