If you never lived where it snows and were moving North to where it does snow, what would you have liked to have known? What would you do to prepare?
I’d go somewhere in-between to keep things dry.
Condensation around windows and outer walls make great growing grounds for mold. 15°C is the recommendation here.
Shit can happen. Boilers break. Leave your faucets dripping and run your circulation pump off of a battery and inverter to save your pipes.
18°C is recommended, especially for uninsulated pipes and where the ambient heat may have trouble reaching, as these spots may get colder.
More importantly, check your home insurance coverage policy, some will set a minimum temperature to maintain to be covered, with some exemptions in case of a power outage and other things outside of your control.
