Winter is coming and I need an ATO. I have been able to manually top up, but my new furnace strips humidity out of the air like crazy.
So. In looking at ATOs, I see there’s two types of sensors. Float switch and optical sensors. Is there any significant difference between the two in terms of precision, reliability, longevity, etc?
What models would folks recommend to a person on a budget?
What are the odds of being able to DIY an auto top off? It seems like it would be pretty straight forward really. Anyone done this, if so, how do you find it working for you?
