    If you're not converting to gas, don't bother.

    The average electric storage tank is already 90-100% efficient; any savings will be offset by higher install/repair costs.
    General public's attitude towards our energy predicament: "I reject the reality of finite resource depletion and substitute it with my own; energy is infinite, we just need an alternative storage medium to run the cars on. The economy can grow indefinitely - we just need to "green" everything! Technology is energy! Peak what?"

    The power requirements are alot more than water heaters. The whole house models usually require 2 - 40 amp breakers. You may want to have an electrician determine if you have the capacity for it before you buy it.

    20-40 amps for whole house instant water? that's not enough even for a single shower!

    I am not sure if you misread or not but the electric models need at least 2 as in 2 individual 40 amp breakers. Larger Bosch models require 3 individual 40 amp breakers. See link for specs. http://www.heater-store.com/images_templ/bosch-water-heaters-ae115-specs.pdf
    I think thats why most people stick with the gas models.

    With the electric model, I would like to see how fast the dial spins on your electric meter when you turn on the HW faucet.
    WOW.

    I am very perturbed by Bosch's tech support. They wouldn't answer the phone, never returned calls. When I stayed on hold for 2 hours and got through, they gave me bad information, then wouldn't take back the wrong parts they sent.

    I have a quietside in my house and love it. Pros are lower gas usage and for me being able to gain lots of extra space for my laundry room by removing the tank. Cons you need to ensure your gas line feeding your house is large enough to accomodate the extra btu's as it will be a fair amount more. Mine wasn't. Also installation can be a real bi@@@ch at least is was for me running the pvc lines as they were 4 inch. However some other models can use a stainless liner in your flue I believe. Oh yeah expensive as heck to do but I am happy with mine and would pay someone to do it next time j/k

    Realize that an instant water heater raises the water temp about 40 degrees, if your incoming water temp is in the 40-50 degree range ( a 80-90 dregree shower is not what most folks want) you will need a small 20 gal. electric to pre heat it up. Especially if you are north of the Mason-Dixon line. Ranni has a good info on this issue. And they seem to want to make sure the installer gets it right. Hope this helps.
    So you didn't ask, what you though was a stupid question. Now how, are you going to tell the boss about your stupid screw up?

    In these parts, people swear by Rinnai. Others just don't cut it. I wouldn't have an electric "on demand". And since you have gas already, you can probably profit by installing a gas one.
    No reserve. No retreat. No regrets.
