I got allergies pretty bad. I do not miss heating with wood. However, I do recommend a non electric heat source. The future of the gird is a bit in turmoil. PEriodic soures like solar and wind, transmission delays. Large new loads from making companies electrify, like cement steel and glass plants.
I do recommend heat pumps. I am the installer for the family. Pioneer pumps can be had for like $1000 each for 18k btu ones. A 18 and a 12of them keep my 2400sqft 2x6 firberglass house with 20 year old windows warm all witner. Wife like's it cold an no heat upstairs. Did that when heating oil was pushing $6 a gal. at 17 cent a kwh its like having $2.30 heating oil.
I you suspect water freeing in inaccesible areas, install heat trace. Insulating pipes has its ups and down. Can make things worse in just the right spot.
Neighbor years ago had a double wide with no basement. Spray foamed the underside. Pipes froze that year. He had to dig out the foam. Try hard not to use exterior walls to run pipe. Especially if you plan on running the heat low.
IF you get wifi, they have leak detectors. Sense constant flow on your water system. Not sure if they have remote shutoff valves yet. Would be easy to do if they don't.
Speaking of electric, might want to get the fuse box solar ready too. A run on conduiit, extra space to run a disconnect box for it.
