Verified Purchase & Recommended Product
I installed the 7kw heater to boost the water temperature at a sink in the garage, far from our main water heater. It does the job; no more waiting for the water to warm up to wash my hands (or using freezing cold water).
This heater may not be adequate if your groundwater is cold or you need a high flow rate (shower, dishwasher). Our groundwater comes in at 45˚F and this unit is not able to make it hot without help from our main water heater. But as a booster for the sink it works great. It activates at a low flow rate, so you don't need to run a lot of water to have it hot.
It is compact and fairly easy to install. It fit in the cabinet under the sink. There were, however, no instructions for the electrical connection; I was initially confused by the wiring. The unit comes with a short cable out of the bottom so you don't need to open it up to connect the wiring. The cable had three wires—black, white and bare (ground). I always thought white was neutral, but in this case it is the other hot (usually red). Since it is a straight 240V appliance, it doesn't use a neutral, just the two hots and ground. Once I figured this out, installation was straightforward.
The 7kW unit draws 29 amps, so it requires heavier wiring and a dedicated circuit; I converted a 30A circuit that was previously used for an electric dryer.
I would recommend this for a single sink if your incoming water is not too cold and you don't need high flow rates. If you need more than this, then you should consider a bigger unit.
