Hey Folks... Looking for some of your own experience and input. I have a modular home that heats with heat pump and a vented gas fireplace (which is useless as all the heat goes up the pipe) Is anyone familiar with why non vented fireplaces are not put in on frame modular homes???? MY main question is this... If you have an outside heating unit..... Do you like it.... Do you find it cost effective.... How much can I expect to invest ....... my home is 2000 sq ft. Can I realistically heat 2 homes with one stove???? my mom lives beside me. she is 75 and has to climb stairs everyday to fix her fire. If I can heat 2 homes...that would help her. Any input you give is appreciated.
