no it really is about 1 kwh per day or 40 watts from average elec 40-120 gal wtr htr

4 watts is less than ur typical night lite and any rocket scientist can feel the loss off the top of tank alone is way more than that

no mistake

By the way, after 20 years of service my tankless water heater (Acutemp C150 by Keltec) wore out because our tap water is so corrosive it destroyed the all-copper, 3-tube heat exchanger assembly housing the 5-kW element. Our tap water has over 387 pCi/L of Radon-222 & lots of water-radiolysis, as you can infer from attached Nucleonica analysis.
> Last Thanksgiving they the heat exchanger onto the control board and blew out the control system. In a panic, I called the manufacturer for a replacement because we used it for both space & water heating.     But the price shot up from around $500 in 1996 to $1700 in 2016. Since they still used a copper heat exchanger, I googled "tankless heaters with stainless heat exchangers" and discovered Home Depot was selling 11 kW ECO-11 tankless heaters by ECO Smart for $209.99, free S/H. So I bought one.       Worked great all winter and we save energy because it's maximum was 140F, not 180 from the Accutemp.CarmineP.S to Nick: Glad to see you are still trying to teach arithmetic to Reuben.
