Optimising domestic space-heating retrofits from nat gas to heat pump
DamonHD:
Hi,
So here is what I expect to spend (some of) the next ~8 years working on, officially starting 9th Jan (and ending, according to my offer letter, in 1931!):

Very interesting. I'll be following this closely.
My mother has been asking about converting her oil furnace to a heat pump. Her house is very poorly insulated, so i told her that would be a better place to start. She isn't excited about tearing the place apart though.
I told her that air source heat pumps aren't viable here as a primary heat becsuse they don't work well below -15c.
I suggested a ground source heat pump. I have the drilling rig to install this. Maybe I'm wrong on this.
Anyway, i know you'll do good work and that this research will be very valuable. I'll learn what i can from it.
Mary B:
They can spray foam by drilling a hole into each stud cavity on the outside of the house, same method for blown in insulation(this will settle some but it beats ripping all your interior walls apart).
SparWeb:
Agree that insulation is better, and don't forget the attic space, if applicable to her house's construction.
Notwithstanding your offer to drill the GSHP loop (a kind offer!) I think it can also be installed horizontally, as long as it is deep enough below frost line. I don't actually know how deep that would be here at 52 degree North latitude...
