I've looked at the labels for electric 50 gallon HWH's and they use appoximately 4800 KwH annually according to the energy label. Easy to do the math to ~ 400 KwH month for a 50 gallon HWH. Even if you don't have a 50 gallon HWH, 466 KwH for a month is far better than me when your electric HWH is factored in. Well done!

I have a natural gas HWH and still used 291 KwH of electricity on my last bill. I was very pleased with that number until you raised the bar on efficiency.
