Yes. If you run the heater without water, the elements will burn out. Unless the heater has a safety limit, that prevents it from running empty.

You can move the water heater to just about anywhere that would be convenient. However, it is not a good idea to reduce the size down from 3/4" to 1/2" directly off of the tank. You will likely run into issues with water pressure. In branch plumbing, it is best to keep the size of the pipe at its maximum until it branches off to a specific fixture. Most ...

It depends on how much you want to spend, how old your water heater is and what kind of water you have. The aluminum rods are usually the cheapest followed by magnesium.

The cable is even made in USA! See here for 12 AWG: https://www.homedepot.ca/en/home/p.electrical-cable--copper-electrical-wire-gauge-122---romex-...

If you want to be fancy and use wire natively colored the official colors, use 10/3. Wire-nut or tape the unused neutral. If your heater is 16 amps or ...

Alternate opinion here. People do not use hot water continuously. They have moments of activity when they shower, wash clothes or do dishes. The rest of the time, the water in the pipes cools off. You know the drill: How long the hot water takes to get hot, depends on the inventory (volume) of water in the pipe. Pipe volume is the square of diameter. ...
