My friends need a wood pellet stove for a 1000 sq ft ranch. They are putting this in the living room. The ranch is a rectangle so I've advise them that it may not heat the bedrooms. Please suggest pellet stoves that are good choices for them in Springfield, MA. Also I am wondering which is better: cast iron or steel. I've been burning a Breckwell P23 for 8 winters and I'm satisfied with it but the service in this area sucks so I'm advising them on getting another brand. Thank you.
