We are expanding our Vermont based farm next year and are building a new house and greenhouse. The house will be pretty tight and well insulated. Using a calculator I came up with a ballpark load of 23000. I'm am not sold on any heating method yet in the house. My wife would prefer not having baseboard heating cause our house is on the smallish side already and any extra floor space taken up will reduce it further. The greenhouse which will be adjacent to the house will have a load between 110,000 and 175,000. I'm hoping to have a boiler to run both and was planning on it being in a shed that connect to both the house and the greenhouse. Any advice on what brands and setup would be really helpful. Thanks.
