Is it less expensive to keep hot water heated while I'm on vacation by keeping the temp at it's regular setting, or should I turn the thermostat on pilot?

When going on vacation we always advise people to set the thermostat to pilot (or vacation setting on some gas valves)... definitely save you some money! Just be sure to note the setting before you touch the thermostat so you can set it to the same place when you arrive home.

It is also a very good idea to shut off your water main at the water meter (or pump)... this way you can be sure you won't arrive home to any leaks or floods.

You would be amazed at how many times I've been called into these leaks when people arrive home from vacations... some have absolutely destroyed the homes so if it is possible please do consider shutting the water off, too.

Questions... just let us know?

I would not only put the water heater on pilot or vacation setting but I would also shut all the water off at the house shut off. Shutting off the water while on vacation is the cheapest insurance against a flood that you'll ever buy.
Trust ne on this and have a great vacation. Tom
