Features

  • TANKLESS WATER HEATER:You'll get an 110V, 3500W tankless water heater. We highly suggest connecting it to a 30A circuit breaker. The LED display clearly shows the water temperature quickly jumping from 82F to 131F, so you don't have to twiddle your thumbs waiting for hot water
  • SAFE, INTELLIGENT & RELIABLE:This water heater is built with a 304 stainless steel lining, a 316L stainless steel heating tube, and a tough ABS shell. It's loaded with multiple protection features, ensuring stable, safe, and reliable heating performance
  • LIGHTWEIGHT, PORTABLE DESIGN:It features a wall - mountable design. It's a great fit for bathrooms or under kitchen sinks, helping you free up valuable space and enjoy hot water whenever you need it
  • EASY TO INSTALL & APPLY:Perfect for kitchens and RVs. It's small and light, and can be installed on side, front, or flat surfaces in a breeze
  • PERFECT AFTER - SALES SERVICE:If you have any questions after receiving the product, just shoot us an email. We'll sort out your problem within 24 hours once we get the full picture
  • *NOTE*:This high - power product doesn't come with a plug, only a wiring device, so you'll need to wire it yourself. In 110V homes, make sure to use a 30A circuit breaker for installation. You can adjust the water temperature by controlling the flow rate (lower flow means higher temp, higher flow means lower temp). The screen shows both the temperature and flow rate. There's a detailed installation video on our homepage for your reference

  • Won’t work without 8 ga wire and a dedicated 50 amp circuit.
Product description is very vague. To install this you would need to run at least 8 ga wire and a dedicated 40 amp circuit to the panel. Won’t work in an average home with normal wiring. Won’t be able to use this. Basically they away $110!

  • Limited heating power
Perfect little water heater. In Panama where water in pipes is already 80 degrees (27c) brings it up to 110 if needed in the shower. Not sure if it can heat it from 30 to 80. Needs 40A power line
