It depends on the amount of flow in the pipes. Running water tends not to freeze. Some vacationers leave the water on a trickle when they go and turn the heat down. Water freezes at 0 degrees Celsius but I would not put your heat that low. Remember the thermostat is on the wall 5 feet off the ground. Some pipes are inches from a concrete floor and thus freeze. 5-10 would be good.

Heat tape is just for keeping the pipes from freezing, it does not heat the water. That's what the hot water heater is for.
yes, as they heat up or cool down they groan
Do your pipes freeze .
The Roman public bathhouses were heated using a series of lead pipes that fed in hot water. The water was heated outside and run down through the pipes which made lots of steam to heat the bathhouses.
It conducts heat and electricity very well. It is good in pipes for keeping the heat in the water.
No this is not necessary. Install the pipes as per usual. You can insulate the hot water pipes up to two meters or up to two yards from the hot water outlet from the hot water tank to prevent this.

The heat gets removed from the H2O
In a steam heating system, the pipes transport steam or water vapor to the radiators to heat the building. Insulating the pipes reduces the amount of heat lost to the surrounding environment. Any heat lost in the pipes cannot be used to heat the radiators, and causes the system to be less energy efficient.
The metal fins on the outside of the hot water pipes radiate heat into the room.
For domestic water, drain lines, heat lines.
I'm not familiar with rumbling in pipes, but the clanking of pipes when the heat starts up is a result of the pipes expanding because of the heat. Heat causes the metal to expand slightly, and the joints creak and clank when the heat makes its way through the pipes.
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
