We are undecided on the cast iron vs. the steel stoves. We like the cast iron HI300 Hampton Stove but it will cost us about $700.00 more than the 1401 Napoleon steel stove. Both say they will heat our desired square footage. We want the best stove for the money, but we don't know if we will really notice a difference over the two. We would appreciate any advice to help us make our decision.
