Reply to comment by SixtyTwoNorth in Electric water heater for outdoor shop, supply with garden hose. Any concerns? by syncopator

Yep, I'm just wondering about unhooking the supply like overnight when it's not in use but I would want to still have a tank of hot water the next day without having to refill or reheat. I'll wrap the tank with a bunch of insulation anyway so maybe I'll just experiment with unhooking the supply and killing the power.

I can't see how it would be an issue to unhook the inlet, just plumb in a shutoff valve on the inlet. It should be fine to keep the power on to keep the water hot over night. Just make sure the relief valve works... :)

Fo sho. I'll also make sure there's nothing important directly above it!

Buddy of mine had the relief valve seize and his water heater. It literally exploded. Took out half the wall of the little closet it was it!

I check mine periodically now :)

Theoretically the tanks are supposed to go vertical when that happens.

Rumor is that a fun redneck game is to take one out to a field, block the TPR valve, crank the thermostat and let her fly.
