I live in a 2000 sq ft home built around 1910 in Columbus, Ohio and want to add heating to our useless 35" x 29" fireplace. We did have the chimney re-lined with stainless steel so it should be good to go. What are the advantages to pellets over wood in this situation? Will I be able to heat the house with pellets or wood? The house is not drafty, but it is not totally sealed either.
