  • High Efficiency for a convenient price
Model: white-7
Very efficient water heater. Simple to operate, simple to install, nice design if installed in a visible place. The only important thing to be careful with is the thickness of the wires and breaker it needs. Recommend : 4 mm wires and a 40A breaker in a 220 V net. In cold winter weather, if the inlet water is too cold, set the desired temperature, but close the faucet a little bit to reduce the flow. This can help to increase the hot water temperature by reducing the amount of water that flows through the heater. ... show more

  • Works well
Model: white-3.5
After a few installation issues ( due to my fault ) it appears to work fine, Had problems with no flow but discovered there was a hose I used with a check valve in place, I have no problems with it thus far so for now it's all good

  • Disappointed Customer
It worked fine for about 2 weeks and then gave an error code of E4. I tried to get tech support for the code or explanation to no avail! I would love to resolve this issue and change my opinion of the service of the supplier would help me!

  • It works with one major caveat...
Model: white-3.5
This small heater works fine if you don't need much volume. At about 1/3 the normal volume of the cold side, the water gets quite hot. But when you increase the water flow, the temp drops quickly. And that is with 65 degree or so cold water inIet temperature. That translates to a 50 degree rise or so. If you have warmer water to start with, you could increase the volume proportionally. I have it on a 30 amp 230V circuit with 10 gauge wire so power is not a factor, it just has it's limitation. But for a shop sink where I wanted hot water to wash hands, occasional dishes and parts, it works great. ... show more

  • Things are going good now😁
No review.. I have yet to get it to power on. And I need an installation manual my Biselong electric water heater did not have on in the box. Okay so the guy doing the electrical got it all figured out and it’s a European colored coded wiring system. So once he figured all that out it was easy to install and works great… ... show more
