He got down to look at the pilot light on the water heater. If it had a big red breaker it was an electric water heater. If it was a gas water heater any amount of electricity usage would have no effect. If you are going to use mechanical or electrical excuses in you plot, either learn how things work or cut back on the details.
"Even though gas water heater uses natural gas as its primary fuel, some models do indeed use electricity to get the pilot light burning. This piezoelectric starter makes a spark, which ignites the natural gas to start heating the water you'll use to take your nice warm shower."
This is how they work Europe and even models in the states. Either way...fuck sake guy, you most be a fucking blast at parties! lol. Great story, pay no attention to Larry the Plumber.
