Our electric bill has been running pretty high even though it hasn’t been that cold and we’ve been supplementing with wood heat. Decided to track down the culprit and hooked up an energy usage monitor to one of our 5 sub panels. Gonna check the other 4 over the course of the next few days.

3.16 kilowatthours
Ie, 1kw of load for 3.16hrs (or 69.3hrs at the 45.6watts shown)
That’s only one hot leg. The other measured about the same. So a little over 6 kwh over a span of about 4.5 hours. That’s mostly from using the range, oven, and a water heater.
I would definately look at the water heater if it’s old. Might have a lot of sediment built up. That and duct leaks and hvac filter. Best to collect a baseline before you make changes though.
Thats a good suggestion. We have two water heaters. This one is 26 years old and is somewhat hard to maintain because of its location. I’ve been dragging my feet on doing anything with it since I’d ultimately like to eliminate it.
You might also check for hot wster leaks somewhete.
