My husband is considering an old Jotul 118--I think it was made back in the 70s. It's been reconditioned. The seller bought it from an elderly couple who didn't want to heat with wood anymore and used a kit to reseal all the seams. He lit a fire in it while it was outside and said it did great. He wants $650 firm for it. I would like to know if this is a good price,or is he asking too much? Also,how many square feet did the old Jotul 118 heat? Any other information about these stoves would also be appreciated. Thanks!
