I feel so much better reading this... I was afraid I was doing something wrong with the 30. 3 full loads of BL a day are keeping the house at 70 with minimal involvement from the heat pump.
Only time I really notice it hard to heat the house is when it's cold out, like close to -30*
Nate, can you give me a brief description of the construction of your home? ie. 2x6 framing, on a slab, or brick constuction with a poured foundation. My house would simply freeze and implode under those conditions.
Pretty standard construction... a 3-4ft apron around the house/garage.
Pretty standard construction, nothing special. 2x6 walls, R21 insulation. On a slab which is heated if I run the boiler. Sides of the slab have R10 as well as a 3-4ft apron around the house/garage. Attic is R60
Got it thanks. Standard doors and windows as well?
Really nothing special
A what?
Shallow frost proof foundation? I did this on my crawl space (foam down the o/s walls and out horizontal over the footers ). Probably more common in slab foundations where you're on grade - my guess...?Not sure what it's called in the trade, I googled it to find a photo to post and I can't find anything. The rigid foam insulation is put on the flat ground at about footer level all around the house. Helps with the slab to ground "barrier" I guess?
Do you have spray foam in the walls? how did you get R21 in a 6" cavity? Maybe you have that foam board under siding on the outside? 6" batt insulation is only r19, so i guess you have the 1.5" rigid foam boards on the outside which i think are aomething like r1.5-2ish?Pretty standard construction, nothing special. 2x6 walls, R21 insulation.
