There is a Jotul 507 for sale on ebay. It is a green model. It has been listed for a long time and I see it has a short time left. My Jotul is green and is still hammering away. The 507 can be run at very high temps for very extended periods of time without damage. This winter I have run my Jotul at temps of 700 F to 875 F 24/7 (October 1 to present). I have run it at 900 F once for a short period of time. The manual states that under intense firing the cast iron can exceed 932 F. At 900 F the interior cast pieces and fire brick start to glow yet the outside cast housing never got as hot as the inner casting or fire brick and at 900 F the burn time rapidly dropped to just two hours on a full load of coal. The manual doesn't state that the 932 F is the limit. I believe the stove could easily withstand a firing of over 1,000 F, however, I'm not willing to risk the stove and see if it can. The brick and cast are still like new. My Jotul heats 1060 sq. ft. to a temp of 68-72 F all winter. For a stove that ony has a maximum btu output of 42,400 and a heating capacity of 3,000-5,500 cu. ft. it sure can heat well and burn very efficiently. When it is very cold outside I mix stove and nut coal to get a good hot burn and a longer burn time. I would love to find a red one at a decent price. I will have burned three and a half ton in my Jotul by the end of this season.
Freddy, for that price it is a deal. Even if it isn't perfect or it is in poor condition it is worth it just for parts. I purchased one for $50. and had planned on keeping it for parts, however, this summer it will be refurbished and possibly pressed back into service as a second unit in the house. My question is: Can you power vent a Jotul? If I can power vent a Jotul I would definitely install the second unit in my house. Approximately how many sq. ft. is 5,500 cu. ft.? I have not found a conversion formula for cu. ft. to sq. ft. From my experience with the Jotul, they are a solid and almost an indestructible unit. It is a shame the Jotul is no longer in production. Freddy, if the unit your looking at has been over fired, you will see small cracks in the grate, grate support, and the cast deflector shield under the top cover. Also the inner cast pieces and fire brick should look like crap as well. Even in this poor condition it is still fixable. If the enamel coating on the stove has signs of bubbling I wouldn't mess with it, not even for parts. This is just my two cents on the Jotul for whatever it is worth. Freddy, keep us posted on the stove and if you purchase it post some pics.
