Double Pane Window Update

Just a quick note about the first few weeks with the new windows mentioned last month. The latest electricity bill is 40% less than the average for the same month in the previous 3 years. There is obviously a lot of variability between years due to different weather etc. but I think this is very promising, especially as the bill includes only about 3 weeks with the new windows.

I also think the house is more comfortable; a bigger temperature gradient across the window means smaller temperature gradients inside the house, so the whole house is closer to the temperature at the thermostat.
