Insulated coops are nice and more usable. I insulated one small part of my coop last summer (only one part, because WOW
one roll of insulation and a few sheets of plywood are very expensive up here). The insulated part just stays much warmer, even when fully vented, simply because my very strong and cold wind can't rob the heat as easily.
As to water...what you do greatly depends on 1. How often you can carry water out, and 2. How reliable your electric is.
My electric is terrible, and I can usually carry out water quite often. So, we carry out water three times a day,
until it is so cold that the water freezes into a solid block in one hour or less. Then I use a stock tank deicer in a black rubber horse feed pan. That stock tank deicer can thaw itself out of a solid ice block very quickly, and those flexible black rubber pans are WONDERFUL, and immensely strong. You can smack them about to pop the ice cube out without breaking the pan.
I wanted to connect the coop to the house, but the spouse said no.
We have more than enough land for oodles of coops, except that I need to
1. Be able to see the coop from the house to be able to check on things (predators, boys having left the door open, etc.)
2. Be able to haul water to the coop in the dead of winter through blasting winds and heavy snow
3. Be able to get electric out to the coop if I need light (some breeds really need light to keep laying, and it is nice to be able to thaw the water when it is super cold)
Those restrictions GREATLY limit where I can put coops, especially since the spouse doesn't want to be able to see another coop. Makes it kinda impossible actually.
