Product Description

Save water by eliminating the wait for hot water to reach the faucet. Simply tap into the water line and install the heater directly at the sink. No need for costly recirculating lines and pumps. And when you want to eliminate the wait for hot water but need more volume, install the Eco smart heater in-line with a larger hot water source, such as a tankless heater or a storage tank heater. Lightweight and compact, these units plug into a standard 110 volt outlet.

WARNING:

CHOKING HAZARD -- Small parts. Not for children under 3 yrs.

Using as Garage Sink Water Heater
4 Stars
Using as Garage Sink Water Heater
Taking 1-star off because mine did not come with a wall mounting bracket and the 'Ecosmart' logo on the front faded off a little while I was handling it during installation while wearing a rough-textured Carhartt jacket. It is supposed to come with one, but all I got were two bolts intended for masonry. Clearly someone took the bracket and returned this to Amazon. I was able to fashion a mounting bracket after going to a local hardware store and seeing what the bracket actually looked like on a display model of a Bosch unit.Anyway, it's depth is about 12" -- it's not a svelte little thing like comparable tankless water heaters are. It'd definitely take up a lot of under-sink space if you're installing it there. I'm hard pressed to notice any noise from it. It makes about the same "quiet boiling" noise that my 40 gallon electric water heater does in my house after a shower, but notably quieter. It isn't particularly heavy, but does have some heft to it, especially when loaded up with water.I chose to run a dedicated 20A circuit with a GFCI outlet for this unit since I was so close to the panel, I already had extra wiring/receptacle from a remodel, and my garage walls are open stud right now, but I'm confident that's not necessary in most cases, especially if you'll be using a 20A shared circuit. My nearest plug was a 15A shared circuit to which all of my tool and lawn equipment chargers are plugged in, and I didn't want to have any problems -- when they're charging (which, for me, is often at the same time), they can chew through electricity at about 12A total. This water heater only seems to spike power draw when it heats its first batch of water after being drained, after that it looks to be using very little power. It had the first 2.5 gallons of water painfully hot in about 30 minutes after the installation was complete. I piped the PRV to the sink below (the photo shows before I mounted the PVC pipe to the stud). I used PEX and a fancy PEX hanger system I found on clearance at Home Depot. Since the pipes are mounted to an outside-facing wall, I covered all the PEX in pipe insulation foam (not all of that is done in the photo).Now, this isn't as high of quality as the higher-dollar units of similar design you find with more recognizable brand names. For one, the inlet/outlet piping is clearly steel instead of brass, which will rust and already was a bit. I cleaned off the little bit of rust at the tip of the inlet/outlets, Teflon taped the everlovin' out of them, and attached 1/2 NPT to PEX adapters, then piped the rest of it as you see in the photo. After a little scare where the hot water outlet was leaking, all I needed to do was tighten that PEX adapter down more. After that, no leaks, no issues. Given the inlet/outlet pipes are steel and were already showing signs of rust, I don't expect this thing to last as long as a unit that is made with brass or stainless piping, but it was less than half the price. And if it ever leaks, it'll leak directly into the big utility sink below it. In conclusion, it works great, I got it for a cheap price, and it serves my needs well.
