Shutting down water heater while gone? - Bill Mains - 12-22-2015
Have gas(propane) water heater. When we travel can I just shut off water line that feeds cold into the heater and turn thermostat to vacation mode? Rest of house water needs to stay on as we have pets that a friend gives fresh water to daily. Thanks...Bill

Just turn the heater control to vacation. No real advantage to shutting off the water to just the heater.

Do you have a check valve or back flow valve on your water main? Do you have an expansion tank on the water heater? Would it still be in service?

No check valve or back flow on main line. Yes, have expansion tank on hot water line leading out of water heater. Just wanted to shut off main water line into tank in case it leaks. Thanks....Bill

As long as the expansion tank will still be on line with the heater, go for it.

My parents used to do that when they closed down their vacation home. But they had to drain the system first. If the water freezes it will burst the pipes.
It does not pay if you are not going to be away for a long time. Too much effort to drain the system.

He's just talking about shutting of the domestic water heater, not heat to the entire house. No draining required

It would be a pretty convenient time to drain the heater anyway.
