Can the monitoring room be heated with hot water?

I don't know what hot water you use to keep warm, or just put it on the floor. Isn't that the same as the bathroom! As long as the temperature of the monitoring room is between 0℃ and 40℃, the humidity should not be too high.

You mean to heat it in the radiator with water. No problem. The environment where people can work normally is not too harsh, and the places are generally ok, with no high requirements.
