This seems to be a well made instant water heater. Got this for under our kitchen sink because for some reason it takes several minutes for water to get hot, which just wastes both time and water every day. Having a water heater right under the sink means we get instant hot water anytime we need it, and can adjust the temperature easily to anywhere between hot and scalding. I'm not sure how much power this water heater draws but it is probably pretty limited when not running. Overall it works well, and I'm happy with it.

It saves on electricity. It uses electricity only when the water is turned on. The one problem is that it takes up space underneath the sink. It's too bulky to put on the counter or on the floor. It has to be underneath the sink. I dont' want to put it in the wall due to needing access to it in case it needs fixing. I also like that the water temperature can be adjusted. Having little kids turn on the hot water and burn their little hands is not fun.

6500W Tankless Water Heater,240V Electric Water Heater With Digital Display, Frequency Conversion Instant Hot Water Heater On Demand Water Heater (Glossy black) The water heater comes economically packaged in a plain brown recyclable box. Inside the box, the water heater doesn't have very many pieces to it, it's all pretty much one piece. They pad the main unit of the water heater well with an airbag using recyclable plastic, and there's another small baggie with the instruction manual and a wall bracket. The instruction manual, right on the front page has a QR code to scan and get an installation video. That's a very helpful thing to have. (I don't know how many times I refer to YouTube to repair something, so this is a plus on the manufacturer's side.) The instructions do note that the instant electric water heater must be installed by a professional, so unless you are 100% confident with your electrical and plumbing ability, I would have this installed by a pro. The instructions go on to give a lot of requirements for the electrical side of the water heater. They note that you should install a dedicated Earth leakage circuit breaker, so if you're replacing an existing electric water heater, you might need to put in a new breaker. (Reading through the instruction booklet, this seems to be a very specific breaker, so check your current one carefully. My house is 20 years old and I'm pretty sure I need to replace the breaker on mine) There are a lot of very specific requirements for the installation of this heater, so I agree with the manuals first recommendation, you should probably retain the services of a plumber and / or electrician. Looking at the instant heater itself, the power cable on it is fairly short, about 2 ft. You don't have a wire long enough to reach it from your existing heater, you may have to have an extension wired in. On the unit are very simple, other than the electrical connector, there are two water connectors, inlet and outlet. Recommend a heater specific shut-off valve near the heater and a pressure relief valve. I'm pretty sure I don't have any of those with my current electric tank water heater, so I'm going to fall back on getting a professional to install this.

I recently ordered the Antuony 6500W Tankless Water Heater to replace my outdated and inefficient traditional water heater. This sleek and modern unit has exceeded my expectations, providing a continuous supply of hot water on demand while saving space and energy. The first thing I noticed was the water heater's compact and stylish design. The glossy black finish adds a touch of sophistication to my utility room, and the wall-mounted design frees up valuable floor space. The digital display is clear and easy to read, allowing me to monitor the water temperature and adjust the settings with ease. Its performance is truly impressive. It delivers hot water almost instantly, eliminating the wait time associated with traditional tank heaters. The 6500W power output is more than sufficient for my household needs, providing ample hot water for showers, baths, and other daily activities. I appreciate the energy efficiency. Unlike traditional tank heaters that constantly heat and reheat water, the Antuony tankless heater only heats water when needed, significantly reducing energy consumption and lowering my utility bills. The frequency conversion technology is another standout feature. It automatically adjusts the power output based on the incoming water temperature and flow rate, ensuring a consistent and comfortable hot water experience. Overall, this small appliance is a fantastic investment for anyone seeking a reliable, efficient, and space-saving hot water solution. It's a modern and innovative appliance that delivers endless hot water on demand, reduces energy consumption, and adds a touch of style to any home.
