Thanks for your question! It’s definitely been more about passion than payback. The energy savings are there for sure, but for me, the real value has been in the learning and doing as well as the result, house climate control with constant comfort.

I will have to wait for a year to compare the data of total gas cost with the previous year.

If I was renovating and starting from scratch, I would probably invest in a ground source heat pump, which can offer climate control in summer and winter.

I figured something along those lines - great project. I always find it amazing how much more efficient we can make home energy systems but there is no economic incentive or level of talent in the market to make it work.

I mean at the end of the day home energy is more about comfort then efficiency and is relatively small money economics.
