      It has one burner that requires 220V. Be sure that you are sizing correctly
      - too small and you won't get the hot water you need - too big and you
      waste electricity. This one works great for our bathroom, but really
      struggles to supply hot water to the washing machine in the winter.

      Keep in mind that I think it was a 50amp power supply so be sure you can
      make that happen. Won't believe how small it really is, shocking, but it
      has done the job just fine.

      A:

      If you keep the flow around 4 gallons per minute it will do very nicely and output about 110 degree water into your hot tub. The more water that is flowing, the less temperature rise you will get. I use mine in a wash sink and with the heater turned up to the hottest setting and wide open flow(about 3 gallons per minute) it will get about 145 degrees. The thing to remember is that this unit requires a 60 amp service and can be expensive to install. It will fill your Juccuzi if used as I mentioned above.

      Hi;
      Probably not,
      You can ask Rheem on their site.
      It will produce water at that temperature, but it will be a small flow of water.
      Rheem makes a larger natural gas continuous water heater 95 series.
      This has a good flow of warmed water.
      It can also replace your hot water tank, as long as you are not filling your Jacuzzi and showering at the same minute.
      CPO, Amazon, Home Depot & Wal-mart online sells them.
      Its about $1,200.00 for the largest size, but you can remove your hot water tank.
      Note: they sell both 'N' natural gas,
      'P' propane.
      Available indoor or outside units
      (outside units needs no venting).

      A better reference would be what applications are you looking to supply hot water to? For example, a two shower home where both showers would be used at the same time would require a higher KW unit to meet those demands. Tankless units are restricted by the GPM they can provide at the desired temperature.

NOW if you wanted a propane model Marey has a 5 litre unit inder $200 which I use in my vending truck, you do need to vent it but it is also a nice unit..

      Electric Tankless Water Heater for a bathroom and it works perfectly year
      round (we live in Arkansas and have rather mild winters). In the kitchen,
      we have an 18 kW tankless water heater that services a second bathroom, the
      kitchen sink and the dishwasher (and, I believe it could handle more). If
      you will only be using yours for your kitchen sink and bathroom sink and

      Can you answer Ashley's question about this product?
      Hi Ashley, In my opinion If you are losing Hot water after 5 minutes you definitely have an issue with your present hot water tank/supply you must have a VERY small tank.. Any how the 13kW Rheem supplies a constant flow of warm/hot water. I use the term warm/hot because depending on the Incoming water temp and the flow rate it going out (through the shower head) it will effect the water temp you are showering with.. A simple answer would be “yes” it will keep it from going cold on you..Will it give you scalding hot water? the incoming water temp and outgoing flow will effect your temp..Make sure you have the proper wiring for the heater and proper Circuit breaker. I installed my own,.In the spare bathroom, it gives warm/hot water yr round in PA..

      A:

      It all depends on how hot you like to shower and how many gallons per minute is being used by the shower. I use mine on a wash sink in my shop and with the faucet all the way open it will burn me if I turn the temp control up too high. The other thing to consider is the electrical demands this unit has. It will be very expensive to run the required electrical especially if you install this very far from the breaker panel. From your description of losing hot water after 5 minutes it sounds like it is fine until then and then your existing water heater tank runs out of hot water. It would probably be way more cost effective to install a larger water heater. This unit will give you plenty of hot water under normal shower uses, but keep in mind the cost to install and if you have a big enough electrical service to your home to support its operation. Draws 55 amps while heating. Hope this helps. This is a great unit when working under its intended conditions, which is what you are doing.

      Yes, but it needs electricity to heat the water.
      You may need an electrician to install this unit.
      You will need to add a 220volt 60 amp breaker in your electric panel, for this model.
      The wiring going from your electric panel to this unit must be enclosed in conduit, and grounded.
      This heating unit alone will heat water for a shower continuously, you can stay in the shower as long as you wish, it will never run out of hot water.
      *It may not heat enough water for *both a shower and a clothes washer at the same time tho.
      but, If you currently also have a hot water tank, install this unit on the warm water line side, and the closer this unit is to your shower, the sooner your shower water will become warm.
      Home Depot has all the wiring and supplies you may need!
      About $75.00 - $100.00 + labor to install.
      For best advice, you can ask the manufacture, include the model number...

      Your hot water heater is probably full of sediment, or an element has gone out this is a good booster unit but works best with back to back installs. In other words two of these units hooked together will run a whole house. Start at cold in on first one then from the hot on first one to cold on second one then hook to hot water line. Requires 2 60 amp breakers and 2 #6-2 wires to be installed at main panel to hot water heaters

      A:

      I have personally found that "on demand" water heaters are a great
      invention. However, it's very important to "size" them correctly. Size is
      based on how much "heating" is required to raise the water temperature to
      whatever heat level you desire from the temperature as it arrives in the
      heater. We have two on demand water heaters - an 18kW and this one 13kW.
      We live in Arkansas which has relatively mild winters and the 18kW rocks
      the kitchen, the dishwasher and one bathroom, but the 13 struggles during
      cold weather to heat the water for our washing machine (works fine for the
      bathroom spigots), and actually requires turning the cold water completely
      off, then turning the hot water down to about half speed so the unit has
      the time it needs to raise the temperature of the water.
      I hardily recommend "on demand" water heaters, but I would consult a
      professional as to what size will work for your circumstances - I obviously
      should have. Good luck!

      I'd recommend putting the water through filtration prior to its connection to the hot water heater, if the unit gets too much sediment it will stop working. It's great running for a minute or so, not sure how long it takes to wash a horse so might want to go with the unit that's larger than this one.

This Limited Warranty does not cover any labor expenses for service, repairs, reinstallation, permits, or removal and disposal of the failed water heater, or defective component part(s). All such expenses are your responsibility. Rheem will pay the transportation costs for an “in-warranty” replacement water heater, or “in-warranty” replacement component part(s), to a convenient delivery point (selected by Rheem) near the place the original water heater, or original component part(s), is located: such as a local Rheem or Ruud water heater distributor.You must pay any local freight charges, including the cost of returning the failed water heater, or defective component part(s) to a convenient shipping location (selected by Rheem): such as a local Rheem or Ruud water heater distributor.

Rheem will not reimburse any party for these, or any other, fees not specifically covered in this Limited Warranty document.

HOW TO OBTAIN WARRANTY CLAIM ASSISTANCE

Any claim for warranty assistance must be made promptly. First, determine if your water heater is “in-warranty” (that is, within the Applicable Warranty Period).You can determine your unit's warranty status by adding its Applicable Warranty Period to its date of installation. However, if you do not have documentary proof of your water heater's date of installation, your unit's warranty status will be based on its date of manufacture. The first four digits of the unit's serial number represent the month and year it was manufactured. Add the Applicable Warranty Period plus ninety (90) days to the date of manufacture to determine whether the water heater is still covered by this Limited Warranty.You may also determine your unit's warranty status by obtaining the complete model number, complete serial number, and date of installation of your water heater and then accessing the “Warranty Verification” information on Rheem Water Heaters' internet website (www.rheem.com) or contacting Rheem Water Heaters' Claims Department (telephone (800) 621-5622) during normal business hours (in the Central Time Zone) to determine if the Applicable Warranty Period has expired. If your water heater is “in-warranty”, contact the plumber, or mechanical contractor, that installed it for assistance with the warranty repairs, or replacement, required.You may also select a plumber, or mechanical contractor, from your local Yellow Pages to assist you. Rheem Water Heaters' Technical Service personnel are available to assist you (by telephone at (800) 432-8373 or via e-mail at techserv@rheem.com) in obtaining “in-warranty” service or to answer your questions about the operation or repair of your water heater during normal business hours (in the Central Time Zone). Be prepared to provide the plumber, mechanical contractor, or Rheem Technical Service person you call with the complete model number, the complete serial number, and the date of installation of your water heater in addition to an explanation of your water heater problem. If an exact replacement is not available, Rheem will provide you with the current model of your water heater, or component part(s), or a replacement unit with comparable operating features. If government regulations or industry certification or similar standards require the replacement water heater, or replacement component part(s), to have features not found in the defective water heater, or the defective component part(s), you will be charged for the difference in price represented by those required features. If you pay the price difference for those required features and/or to upgrade the size and/or other features available on a replacement new water heater, you will also receive a complete new Limited Warranty (with the full Applicable Warranty Periods) for the replacement new water heater. Rheem reserves the right to inspect, or require the return of, the failed water heater or the defective component part(s). Each “in-warranty” failure water heater must be made available to Rheem (with the rating label and all the component parts intact) in exchange for the replacement water heater. Each defective “in-warranty” component part to be replaced must be returned to Rheem in exchange for the replacement component part.
