Looking for advice on a new build heating plan
I am trying to figure out the best solution for heating our new home and I would greatly appreciate any suggestion from the wise folks here.
The house is in Northern New York, climate zone 6. We have great Southern exposure on the site and went with more of a passive solar design. The house is basically a simple rectangle with two stories and is built into the hill with a walkout first floor that will also be used for living space (attached are the floor plans). The house has a shed roof with 14ft ceilings on the South side and 8ft on the North. For our envelope we have R-20 under slab, ICF first floor, 8″ SIP second floor, and 12″ sip roof and triple pane Zola windows. The energy audit came in with a max heat load of 30,000 btu.
We will have a “hybrid” masonry wood stove from eco firebox on the second floor that we plan on doing the majority of our heating with.
My concerns/questions are:
I’m concerned that the heat from the wood stove will not travel downstairs…
We would really like to stay all electric in the house with plans to add solar in the future. Perhaps a mini split would work with one head downstairs and one upstairs? My concern with the mini split is that it is not uncommon to get multiple days in a row of -20F in our area, and we also travel a fair amount in the winter.
I could easily add some electric baseboard heaters downstairs as well but I am not crazy about the efficiency/looks. I’m also not sure if every room downstairs will need some type of heat or if something in the family room, such as mini split head, could work. Then again, with the mini split, what would happen downstairs on those days of of -20f?
I would greatly appreciate any thoughts/ideas/suggestions! Thanks in advance.
