Features

  • Important: To install the 11 kW instant electric water heater tankless, a 240 V, 60 A circuit breaker is required. Please verify that your breaker panel meets these specifications. Suitable for 2 points of use in the bathroom.

Intelligent temperature control adapts to preset settings regardless of external water/electric conditions, automatically adjusting power for energy and power efficiency.

Includes overheating protection, low water flow protection, dry combustion protection, anti-freezing protection, high-pressure protection, and flame failure devices. IPX4 waterproof rating. Stainless steel heating element with no water storage to prevent sediment/scale buildup.

  • Compact quality and fair priced water heater
Style: RE8K
I recently purchased the Ranein 8kw water heater for our guest house. We are using this for a single shower and two sinks. The unit arrived quickly. It was easy to install and has a very thorough display with what seems to be high quality components. We used the template to place the mounting screws and mounted it under our kitchen sink. So far it works great, the price was excellent, the water temperature will get much hotter than we need it at this time. We did not experience any leakage after install. I expect this will be a great addition to our guest house. ... show more

  • My 1st tankless
Style: RE8K
An interesting product. This is my first tankless water heater and it works great. Easy to wire and install. It takes a few mins to get going, about 3 mins... But once it's hot, it's HOT.

  • Water Heater
It’s a great water heater and the water takes just a second to heat up. It small enough to fit on the wall without being in the way. The unit is pretty durable and easy to run. If you aren’t familiar with running electric you might have someone help you but it’s pretty simple to do!

  • Heater is junk and poor customer support
Style: RE13K
Bought this unit for a cabin at our lake property, worked great for about a month for doing dishes, after I completed the shower constructions I tried to take a shower and it quite working. Only had the unit 2 months and it quit. Tried calling the support center and sit on hold for a few min and then get a message saying all agents are busy and hangs up. Took the unit back down to see if I could trouble shoot more, still not heating up. Call again and hung up right away. Poor customer support, I would recommend not using this unit. Its been a headache once it quit working. ... show more
