Does anyone know what the BTU output of the Jotul 507b is? What would be considered a good price for one?

If it is in good condition, that is all fire brick intact, grates intact and operable, I would say anywhere from $400.00 up. I've seen them go on EBAY for over $600.00. Parts are available but are pricey.

Do you know what the average burn time would be on a full load; hopefully ten hours or more. I want to thank everyone for all of the information. Thanks.

The burn time in any batch-fed stove will vary depending on how much heat you are trying to extract from the stove.. with the air to the fire turned down, you probably will be able to get 10-12 hours from the stove..

How many square feet do you believe this unit is capable of heating at 70 degrees. Also, does anyone know how many BTU this unit is capable of producing. Thanks wayne.

That's another 'it depends' question and answer. :)

The variables are the level and quality of insulation, the quality and quantity of the windows in the house.
The outside temperature and the wind also make a huge difference..

So, it will be very difficult to answer your question.

I live in an old farm house with moderate insulation and have fourteen single pane windows with storms and three windows that are double pane. As far as wind I don't get hardly any wind due to the surrounding hillsides. In the winter I close up most of the house and have about 2000 sq ft. to heat between two floors. Just concerned about the size of the Jotul and its output; I feel I would have to push the unit to the max burn all of the time to maintain the house temp. I do not like to hear the oil furnace run. Thanks. wayne.

I don't know the dimensions of the jotul, but the other pics I've seen on the forum of the jotul's seem like it is comparable to a hitzer 55, which make it around 55 k btu, maybe get a few firebox measurements and do a comparison yourself to known manufactures. You don't have your area, on your profile and if your in maine or southern pa will make a big difference if the stove is big enough.

I don't know for sure but I'd guess its BTU output is not that high. Probably around 40k. I've had burn times over 12 hours with the one in my shop. it's a deep bed of coal so coal likes that. But as Greg said, it depends how hard you run it. It's not reasonalb eot think that the Jotul will heat 2,000 sq. ft. It will cetainly take a lod off of the oil furnace though.

If you are able to get the use of the oil burner down to just once or twice a week or so, then the Jotul will be putting a huge dent in your oil bill.. I wouldn't turn one down if you have a chance to buy one. Hook it up, and enjoy it. If a bigger more capable stove comes along, then sell the Jotul.

Most of our weather is not the extreem cold that the house's furnace or boiler is sized for. Often a supplemental heater will do 98% of the heating needed, just the ocassional -10* with a strong wind will make the oil burner fire up.

I live in upstate NY, not New York City. I clearify this due to the fact that I get that question all of the time. I live in the Tug Hill area where the snow falls hard and deep. Last season I had a couple of weeks of sub 20 degree weather before wind chill. Most of the time it is plus 20 to 0 outside. The unit measures 12" *12"*3'. Still think the Jotul will do ok? Currently I have a wood stove that is around 40,000 BTU and I have to push the stove to keep the house at 68 degrees. Only used the furnace a couple of times last season. I have to keep in mind that the stove is only about thirty to fourty percent efficient. I used twenty cords of wood last season. Let me know what you guys think. Thanks. wayne.

Hi Wayne, are you replacing the wood stove with the Jotul?? if not,, I'd fire up the jotul, and use the wood to suplement the coal. In the climate you are in, you will be working the jotul alone pretty hard,, if you set it to burn for 10-12 hours, then fire up a wood stove for the evenings, you should get by without burning any oil.

The jotul looks like a well made stove, able to work hard, but the quantity of coal is fairly small.. What you need is a Harman Mark III, or an Alaska Kodiac hopper-feed, or a Hitzer big hopper feed... But if you have or can get the Jotul, I'd go for it.

I'm replacing the wood stove so I would be depending on the Jotul for total heat. If the Jotul were pushed how long of a burn time would you expect it to achieve? How much coal can you load in a Jotul? The Jotul is for sale for $400. I am waiting for the guy to call me back. I would love to have a Mark III, however, the price of a new unit scares me. I have not found any used units around my area within a two hundred miles area. I will not burn wood this season; I have already decided that. I'm just concerned the Jotul will not be able to meet or exceed what the wood stove was capable of. wayne.

Hi Wayne, I'm not going to be able to answer your questions.. and unfortunately there are only a few, maybe one or two Jotul stoves in use on the forum.. It may be a bit of a gamble,, but I'm sure you had to feed the wood stove like every 3-4 hours when you were working it really hard.. you should be able to get 6-8 hours at an absolute minumum out of the jotul per load, and that is burning it really hard.. more like 10-12 average.. But again, this is based on general coal stove knowledge, not specific to the jotul..

does your wood stove have a heat distribution fan?? I'd suggest using a fan near the jotul to 'wash' heat off the stove body, this is quite effective to get more heat out of the stove..

Sorry I can't be more help.

Greg L.

You have been a good help. It is nice to have some one with some answers. Burning the wood stove I was feeding it ( I referred to it as the money pit) every hour and a half and maybe two on a good day. The stove is so darn inefficient. I have been burning Elm and Maple for the past two years. I had a nice bunch of elm that got the elm disease. Anyway, I appreciate all of your input. I will keep everyone up to speed as to what happens. The guy who has the stove for sale has yet to return my call. Kind of expected him to return it today. The wood stove did not have a fan, however, I had a fan gently blowing the air around it. I would do the same with the coal stove. Thanks greg.

wayne.
