Tankless water heater
Tankless water heater
(OP)
Does anybody know of a (electric) tankless water heater that is 110/120 volt 15-amp? All I need is something very small. I have 15-amp service available and would like to avoid rewiring for 30-amp as most 120 volt heaters seem to be.





RE: Tankless water heater
This type of water heater was very common in Europe -at least in the many hotels I stayed in. The Europeans simply insert an in-line heater on the cold water line going to the shower in their bathrooms. The electric (220v, but it could just as well be 120v) heating element activates on water flow and trips out on no-flow. I never had problems, except a slight inconvenience of waiting for the water to warm up - but this can be a characteristic of tank heaters as well, if not designed correctly.

I remember seeing the types of water heaters that Art mentions in Popular Mechanics long ago, and I suppose they do sell them here. One drawback is they take more power (while heating) than a tank type water heater, so you have to have wiring work done to put one in a house. The big advertising point they always made was that you had as much hot water as you needed, never run out.
Have you tried Home Depot? I know our kitchen sink at work has a very small tank-type water heater under it, it quite likely runs on 110, though I never thought to look.

A small storage heater is your only alternative.

They can be over sink, under sink, with expansion vessel, without expansion vessel etc. etc.
There are many mainland European equivalents as well.
The Italians and Spanish do some excellent water heaters.

You two might concider a recirculation pump.
I might be less expensive to operate over time.

With additional crossovers you can add the benefit of instant hot water to other outlets and a low cost.
The timeer operates the pump at peak use hours only

The link that pennpoint left above is interesting and I have seen a "homegrown" equivalent that I like even better, but it can require a return line if you still want "cold" water at the location. The system in pennpoints message uses a pump on a timer, which recirculates at specific times, which is convenient but wasteful--to a degree. A similar system can be built with a pushbutton control that recirculates the water without the waste.
Just another idea,
