New bathroom - water supply via barn - risk of freezing?

Hello,

I am new here in the forum and would like to briefly introduce myself. I am Sebastian, 29 years old and come from Lower Franconia. Since 1.3.18 I have been the new owner of a house built in 1900 with a barn. (House was renovated in 2016 + heating from Wolf Feb. 17) I have a question. My wife and I are planning a second bathroom above the first bathroom. Our Wolf system is in a separate room next to the garage (adjacent to the house). The idea was to lay the pipes over the barn (not heated) and then you would come directly into the new second bathroom. Now the company that is supposed to do this said they would not recommend it because the pipes running over the barn would be at risk of freezing on cold winter days. The company also said I should completely open up the first bathroom downstairs and run the pipes up into the second bathroom above. Which I personally do not think is a good idea! Is it not possible to insulate the pipes running over the barn in such a way that they do not freeze? What are your ideas? I was thinking of a 4m drywall partition insulated so that the pipes are enclosed and not directly exposed to the "outside", properly insulating the pipes, there must surely be a way to insulate them when they run in the "open"! The barn is covered, not heated! I am zero a craftsman, so I am asking here

Thanks already for your advice and your ideas

Best regards Sebastian

Insulation is not heating. That means if there are subzero temperatures in your barn, the insulation only prolongs the time until freezing occurs. Outdoors, water pipes are therefore not laid at all, but only frost-free at least 1 meter underground.

Basically, to prevent freezing, it helps to let the water run as often as possible (a lake freezes faster than a river), but as a plumber, I would not rely on that. What do you do when you are on vacation?

Alternatively, an auxiliary heater is also possible.

What also must be considered is that the circulation will run continuously with the hot water and consume a lot of electricity and heating energy. You should really think about electric heating (infrared, underfloor heating, etc.). However, you probably don't have any hot water in the bathroom from that yet.
