Thank you for the reply to my comment.

My heating is actually 18,000 Kwhr converted from litres of propane.

Propane is tied to oil prices and currently 80 cents Cdn per litre, 24,000 btu

There is a federal tax on carbon which added $350 last year and is increasing every year to 2030

Our electrical is actually 8,000 Kwhr and billed on a time of use basis. includes hot water

Both heat and electricity are typical averages for a house in Canada, Zone 6

We keep the house at 55F at night and the same anytime we are out.

I think the real difference is insulation . My house is a storey and half and the upstairs is all knee walls.

I have 5 different attic areas and a real zoo to re-insulate.

The house is a brick facade so the lower walls are also a problem to fix without tearing out the drywall.

The house is surrounded by so many big trees that the solar guy did not want to install.

In any event, my roof area is not big enough for enough solar and is broken up by dormers and a garage roof going the opposite way.

We have electrical baseboards throughout but are too expensive to use.

Your idea of a heat pump for one room and setting it high is a good one.

We are actually on the same page.

great article, well researched and analysed

my house is similar to yours in size and has new windows well-sealed

no obvious caulking spots, all infiltration

however, I use a total 26,000 kwhrs from electricity and equivalent propane usage

I think you stated 11,000 kwhrs for your home plus an ACH of .34?

I have not been able to do the same economics

I believe a blower door test on my house would show 5 or 6 ACH @ 50 pascals

my roof is far too small to make it up with solar

plus would need more than one heat pump

the issue of deep retrofitting existing houses needs to be solved or our climate goals will not be met

FYI. I thought you might want to update your article.

“…solar projects in all market segments — residential, commercial, industrial, utility-scale — that begin construction in 2021 and 2022 will still be able to receive a tax credit at 26%. All markets will drop to a 22% tax credit in 2023, and the residential market will drop to 0%, while the commercial and utility markets will sit at a permanent 10% credit beginning in 2024.”
