I know this type of tankless heaters with nichrome coils are common in some countries. Does anybody know how the "power showers" which are rather popular in the UK and Germany works?
I had a look at EEMAX homepage and in my always humble opinion, it appears like a low-cost alternative but if UL has approved it, it can't be blatantly unsafe, can it?
(I looked at the models on the Norway site and noticed that for the 40 Amp heater a 25A breaker and 4mm2 (#12) cable is the recommended minimum. A bit tight, in my humble opinion)
