  • Perfect 110V Point-of-Use Heater
This is an excellent, compact unit for an under-sink application or a garage shop setup. The installation was incredibly straightforward since it runs on a standard 110V circuit—saving the hassle of pulling new 220V wiring. For a 3000W heater, it delivers hot water almost instantly, which is perfect for handwashing or doing small batches of dishes. The digital display is bright and makes monitoring the exact output temperature super easy. The build quality feels solid, and its small footprint fits neatly under the counter without eating up valuable storage space. Highly recommended if you need an efficient, on-demand plumbing solution ... show more

  • Outdoor shower
Easily connects to the pipes, plugged into a regular socket. I bought this to have an outdoor shower for my swimming pool. I’ll have to do is turn the water on hit the own button on the small heater, and instantly I’ve got warm water to shower before and after going into the swimming.
