First of all, I'm SINGLE and I can guarantee that I only use hot water for one thing at a time. If I'm taking a shower, the dishwasher won't be running etc.
My house is small, 1600 sq ft and I'm trying to decide which way to go with a water heater.
Reducing utility costs is a high priority with this and the calculations seem to point to an electric tankless heater -- (looking at an Eemax 95 unit).
I'll put a low flow showerhead on as well.
Needs 38.5 amps at 240v, no problem and the load box is close by in the basement.
I take quick showers and use cold water for laundry -- rarely use my dishwasher. (I'm not a "hot water freak").
If I were to get a 40 gallon electric tanked unit, how long (based on winter Indiana well water), would it take for the water to come up to temperature?
I know you'll tell me that a timer would be a waste of time but considering my situation, I think I would save considerably. Putting a timer on the heater is something I'm thinking about.
A daily late afternoon shower is all I need and perhaps a few other hot water chores -- I'm sure 40 gallons would do me fine.
Another advantage to a tanked unit is the possibility of adding a solar preheater at some point (something I will most likely do).
So, really my question is --
How long would it take that 40 gallon heater to get up to temperature?
(I would think it would have the "typical" (2) 2400 w elements?)
I think the numbers (if I use a timer) would be damn close to a tankless unit.
And yes, have a water softener ahead of the water heater.
