This review is from: Stiebel Eltron Tempra 12 Plus Electric Tankless Whole House Water Heater, 240 V, 12 kW (Tools & Home Improvement)

After two months of use, I am very satisfied. This 12 KW unit supplies one kitchen sink plus one full bath (with shower) in the guest suite. There is never a problem with instant hot water, and you can take as long in the shower as you like. They make higher capacity units for the same enclosure in case you have multiple bathroom or laundry demands. It was a pleasure to get rid of that wasteful, ugly tank and use the space for alternate needs. In my case, I turned a utility room into a guest kitchenette. Keep in mind you will need to have room in your load center for the added power demand and install the required circuit breakers and wiring according to your local code. Stiebel Eltron specifies the manufacturer's requirements in their (pdf) installation instructions. The extra power demand will likely save power over a tank-type heater that has much more heat loss while idle. Even if you need to hire a qualified electrician, this is a pay-back improvement from tank type water heaters which are also flooding time bombs inside your home. Luckily, I happened to be near someone's tank type heater in a garage, when the bottom cracked/fell out (instead of more common slow, warning leak). When that happens, that little (building-code) drip pan under it is a joke. If your tank type water heater is over 15 years old and not a lifetime warranty, I would recommend preventive replacement.
