Hello everyone. I am new to wood boilers. I have been looking at a few owb's like CB 1450, Heatmaster G200. I want to heat 3500 sq house, water and clothes dryer. I live in central North Carolina where the winters are 10f to 50f. I want to run the boilers all year long. I will have to build a shed to keep the wood dry which is no problem. Right now I am running all electric heat pumps, water heater etc. My electric bills range from 450 in the winter to 285 in the summer. What I am wanting is some direction. I know nothing about iwb's. I know I will have to build a outdoor building to be able to have a iwb. I have quotes for both of the owb's CB 1450 10,300. G200 10,875. Both are with all parts to hook up with 100ft of underground thermopex. Thank you ahead for any help I receive.
