The Goldilocks Problem with Heat Pumps
Why getting your heat pump's water temperature 'just right' takes months of manual tweaking—and how SnugSense learns to do it automatically.
Every heat pump owner knows the struggle:
Too cold outside → water temperature too low → house never quite reaches temperature.
Too warm outside → water temperature too high → wasting energy heating water you don’t need.
The fix? Adjusting your weather compensation curve—that setting that tells your heat pump how hot the water should be based on outdoor temperature.
The catch? Getting it right takes months of manual tweaking. Check the weather. Feel cold. Adjust. Wait a week. Still wrong. Adjust again.
I spent two winters doing this dance with my Daikin Altherma.
Then I thought: what if the system could learn my home’s thermal characteristics and adjust automatically?
That’s SnugSense.
It learns how your home actually responds to conditions—not theory, not generic curves, but YOUR house, YOUR insulation, YOUR windows. Then it adjusts automatically.
No more manual tweaking.
I’ve been running it on my own heat pump since last year. Early results: ~15% energy reduction compared to fixed settings, while keeping the house perfectly comfortable.
