What size circuit breaker is required?

Asked by: jj
3800 / 240 = 15.83a, so use a dual 20a breaker.

Will this heater provide continuous hot water after its 20 gallons are used up or does the water turn cold?
Asked by: Andy
If you are using 1 GPM for 8 minutes, then wait 30 minutes, it will reheat to starting temperature. It will reheat much faster with warmer inlet water, such as 65F in Arizona, while 45F water in Montana will take longer. If you need more instant water, i suggest a 11 KW instant water heater to preheat the water going into this heater. It could warm 2 GPM about 30F (above your ground water temperature) so the tank full of water will last much longer.

Is there one or two heating elements on the 20 gallon Rheem water heater?

Asked by: Ladyhawk
There are two heating elements, 3,800 watts each, and the upper thermostat will turn off the lower element when the upper element is cooler than the set point. Once the top of the tank is above the set point, the upper element will go off, and allow the lower element to run. Once the lower element is hot, then both will stay off until more cold water enters, cooling the lower element that will start heating first. So wattage is limited to 3,800 watts or about 16 amps at 240 volts.

Rated 5 out of 5 by from Easy to install I have Multiple Sclerosis so when things go wrong around the house, I sort of flip out a little bit. I am the consummate handyman and have never used anyone for any service of any kind. But as I lose mobility and energy, it has come to pass that I've had to use contractors. I only needed help getting it put into place and 15 minutes later I was installed. Very nice temperature at the factory setting as it is good and hot but you can tolerate it if you get your hands under it when doing dishes or something. Very nice, industrial looking unit. Your quality shows at least initially. Check back with me in 18 years which is how long my last Rheemglass unit lasted!

Rated 4 out of 5 by from As advertised I made this purchase about a month ago to replace a Rheem of a similar model that had been in service for at least 19 or 20 years. The house had been vacant for about 10. On visual inspection inside the old tank there was corrosion and sediment with questionable water clearity. The inspection took place when replacing both supply and hot water piping a few months earlier. My discomfort kept eating at me about the sediment until I bought the new heater. The physical size is identical, with duplicate wiring and plumbing connections. This may be the last traditional tank heater as I am hearing the manufacturs are soon making "only on demand systems or some call tank-less systems."

Rated 5 out of 5 by from EFFICIENT Didn't really need a new water however mine was over 13 years old. Was just going to get a flushing and my regular plumber suggested I consider a new one before I have any problems. Heard so much about Rheem so it was my first choice. Truly happy with readily available hot water as well as its competitive pricing. My plumber added all new connectors, a shut off where it was supposed to be, a pan under unit as well as a device to detect any water leakage to place near unit. So happy I made the investment - truly have piece of mind and enjoying the efficiency and savings on electric. Diane

Rated 5 out of 5 by from Easy install I bought this unit 2 weeks ago and installed it myself together with my fiancee. I was very nervous to do it since neither of us have done anything close to installing a water tank before, but after getting a lot of advise and researching, I was amazed how smoothly the entire process went. The tank comes well packaged, the cardboard box has convenient slots so 2 people can easily carry it to the designated place and once hooked up, it heated up the water in less than 30 min. We could not believe we have hot water already! Seems well built and durable, so far we are very happy customers.

Rated 4 out of 5 by from Overall great, but.... This seems well built, and love the compact size and the fact that it's he only 3800 watt 30 gallon on the market (most are 4500 watts). I have a rheem nat gas water heater in my main house, and it works great. If I was going to make one complaint - I think the temperature controls should be easier to access. I use this in my guest house/office and unless someone is staying there I keep the temp on low, and hen turn it up if I have guests. However everytime you want to adjust the temp on this you have to unscrew the two metal housings and use a screwdriver to adjust (while turning the breaker off). Kind of a pain considering a simple temp control could be used instead. Otherwise - it's a solid unit.

Rated 1 out of 5 by from No features. I bought this a few weeks ago and on the first day of installation I ran out of hot water. Yesterday I ran out again. Upon checking, Power was to the heater but not to the heating elements. On both occasions, I just touched the thermostat with a screwdriver and started to turn the temp up and with less than a millimeter of a turn the thermostat clicked and power came to the elements. So today I will call support and see what they do for me. Until then my review will stand unless my problem is corrected by support. If corrected I will amend my review.
