For short trips you could leave a hot water faucet streaming a tiny amount of water so there wouldn't be a problem overheating the tank.

Well if it would heat it, I would shut off the electric, depends if it works that good

The only way you would know if it works good is if you cut the electric to the tank. Otherwise the tank will recover in about 30 minutes with electric where it would take up to 10-12 hours with the coal coil..hotblast1357 wrote:Well if it would heat it, I would shut off the electric, depends if it works that good
Don't worry, it will heat it.. Family of 4 here and we use hot water constantly. My temper tank was almost always between 110-150 degrees. Got up to 180 a couple times lol..

Here's a diagram of my hot water system.
"Pardon the crudity I didn't have time to build it to scale or paint it.."
In coal preheat mode
Valve 1 and 3 are open, valve 2 is closed.
Valve 2 stops flow directly to the electric tank and forces it to go thru the temper tank.
During the off season
Valve 1 and 3 are closed, valve 2 is open
Valve 1 and 3 isolate the tank during the summer so no cold water gets to the coil while I'm not burning coal.
Valve 2 allows cold water to flow directly to the electric tank.
