How should I heat a fossil-fuel-free superinsulated garage/workshop?
So I’ve got this super insulated detached barn/garage that I’m building. There is lots and lots of insulation, below slab, both interior and exterior wall insulation, between the garage area and the apartment above, roof and the garage doors are as insulated as I could find.
There is a bathroom in the garage too – so I don’t have to traipse my dirty self back to the house. This means the garage is heated….yeah for me, my workshop, and mantown!
I’m in central NH (Zone 6A) – 8000HDD (Not including this winter), there is no fossil fuel heating on site. I’m struggling to figure out what my heat load requirement will be to heat it. My hunch is to go with an electric radiant ceiling panel in the bathroom and one above the workshop area. I don’t think it will ever get near to freezing, unless of course we leave the garage doors open in the winter. We are using a mini-split HP to heat the apartment above. We have lots of PV too.
Do any of you have a recommendation for what I should use for my heating needs. I was also thinking about just simple electric resistance baseboards – but was trying to avoid them. Is this ridiculous? If I go with it in the bathroom – what would you use in the garage/workshop area?
