Uum

I got this thinking it would work well but I haven’t been able to use it since the electric current in my house is different. However it did come well packaged and with instructions and appears to be an easy install as it also came with an instruction manual.

Easy to hook up, heats up quickly

This immediately feels high quality when you remove it from the box. It's straight forward to hook up, and comes with an easy to follow guide. You basically have the cold water in, hot water out, and the power cable that hooks to 120v at about 36A. It takes about 2-3 seconds to warm up to warm/hot temperature, maybe a second or two more to get fully up to temp, which is much faster than waiting for the hot water to reach from a hot water tank. I haven't had any issue with the RV kitchen sink I installed this in, though I do think the water flow is less than a house could have, so watch that your water flow doesn't go above about 2 gpm or you'll risk getting colder water.Note that you should check to make sure your circuit can handle at least 36A, in addition to other potential loads, or better yet you should probably run a dedicated circuit.

Works very well for sinks

This review is for the Tankless Water Heater Electric 4.4kW 120V, WINTEMP Provides hot water on demand without a storage tank, featuring self-adjusting temperature control, digital display and overheating protection.I have a potting bench with sink in my greenhouse. It only had a cold-water tap.My husband installed this to give me heated water to wash up.He said that it was easy to install. 1/2 inch cold line in and hot line out. This is hard wired and ready for 110v.This worked amazingly well. I set it to 110 degrees and had warm water almost immediately.
