Nice job, Boris. Very good workmanship.

Did you take any photos of the construction of your unit?

I'm a little surprised that you switch from heat pump heating to resistance heating at 45°F. Although the efficiency gets worse at lower temperatures, the efficiency is better than electrical resistance heat, much lower. I would think that depending on your unit, it might be good to 35°F or lower.

Thanks for sharing your project.
