Most Liked Positive Review

Everything as advertised.

Didn't know such a thing existed (120v) until I walked with S.H. tech. It's easy to recommend the waterheater, but it is even easier to recommend Supply House. They cared that I needed it quickly. When the first arrived damaged (in 2days), they were even quicker to replace the first, with a second, within two days. They're NY, I'm MI, it didn't matter. Thanks

Both units damaged in shipping

Ordered two of these for a job with tight timeline. PRV's were both damaged subtly enough that quick visual inspection did not detect but once installed we found both valves were stuck open. Pins were just bent enough to pull the valve open slightly. Had to replace both valves. Didn't have time to send back. Water heaters had not protective packaging for shipping. Not even Styrofoam around fittings. Would not recommend. Gave two stars instead of one only because Supply House delivered quicky as normal.

Perfect size for small space!

This heater has option of water inlet/outlets on the top or the side. We ended up using top and they are hard to find in this size. Heater fit perfectly into the small space under the stairs. Also electric 110/120 was perfect for historic building. Fast shipping too. Awesome!

Heater works great, packaging subpar

The heater has worked without problems. It is shipped in basically a retail box. Lots of dents, the TP Valve was destroyed and leaked, Cold water nipple threads damaged. Replaced TP Valve and nipple, banged out the dents and installed, worked.

Nice product and great vendor

This first unit was damaged badly by UPS, but Supply House sent out a replacement that same day I called. Customer service was top notch. They didn't even make me wait until the return made it back. Water heater itself works really well and heats up quite fast. Comparative brands only have a 1500 w element, but chose this one with the 2500 w element for a faster recovery. Needs a 30 amp breaker though. I liked having top or side connection ports and also has a good quality drain valve.

1. Turn off the heater electrical supply. Do not attempt to adjust thermostat with power on. 2. Remove the thermostat access panels and covers from the thermostats. Do not remove the plastic personnel protectors covering the thermostats. 3. Using a flat tip screwdriver, rotate the adjustment knob to the desired temperature setting. 4. Replace the covers and access panels and turn on heater electrical supply.

Q: I have a new hot water heater. This is the first year I need to drain it. I was told by the plumber when he installed it that you just have to turn the screw and it will drain. That is not happening. Any thoughts would be helpful. Thanks

I have a different brand, same size. A lot of "dirt" builds up. I attach a short hose to clear the area then open valve while leaving the water supply on. Mine works like a charm. You might have to turn the valve off a couple of times and do it again so the "dirt" resettles to the bottom again. Good luck. Bob

If the unit was manufactured to be used on 240 volts it can be used on 240 volts. If the unit was manufactured for 120 volts, you can not rewire the unit and/or operate the unit on 240 volts.

Q: Hello, I am needing a tank for a bathroom in my garage where we'd take short showers and wash our hands. I nave electricity only available. Space is limited. How many gallons would I require for something like this application?

You need to estimate your average usage per hour and determine whether this heater will produce the amount of hot water you need based on the specifications. This heater will work for approximately one shower per hour depending on the water usage of your fixtures and the length of the shower.
