Video Transcript for Review of Atwood RV Water Heaters - Standard Water Heater - AT94022

Today we're going to take a look at the Atwood RV 10,000 BTU Gas and Electric Water Heater with an Automatic Pilot and a 10 gallon tank. Now this RV water heater uses an automatic direct spark gas pilot and an internal electric heating element to supply hot water very fast to your RV. It is a quick recovery water heater, provides a nice, long-lasting supply of hot water, with a nice small, lightweight tank. It'll produce up to 20 gallons of hot water per hour. The tank is an aluminum clad tank, reduces calcium build-up, helps limit corrosion, eliminates the need and an anode rod.If you notice the connections on the back here, you got your hot water outlet right here on the top and your cold water inlet right here on the bottom. Both of those connections are a half inch NPT connection.

Let me open the front door here and we'll show you the pilot. Turn that and you can drop your door down. Then right here you have your automatic, direct spark gas pilot, which will heat your water once your destination is reached, and it will supply hot water in less than a half an hour. It does relight automatically until your heater is switched off. It does use a U-shaped flue tube to distribute more heat from the burner up to the water, and it gives you an 80% heating efficiency rating.The gas line, which will come in the back here, come through here, and connect right here.

It is a 3/8" flared LP gas line connection. The electric heating element will assist the flue tube to heat your water faster. It's an incoloy construction, which prevents burnout, and that's a nickel-iron-chromium alloy construction, with less than 50% nickel content.It is thermostatically controlled to prevent overheating, has a high temperature limit switch which will automatically shut off the unit, and it does also include this double panel switch right here, which will allow you to power your electric and gas components on and off individually. It's designed to mount in your coach for a nice, easy operation. It does use a pressure release valve to prevent excessive water expansion.

Has an air pocket in the tank to keep your valve from dripping in your cabinet. It does use a combustion shutter to adjust the oxygen level in your pilot light for high altitudes. It's externally sealed to keep the unit clean.The drain plug on this is nylon so that helps prevent rust and you can see the white access door is all included. All your serviceable parts are right up here, very easy to access. Go ahead and close the door, and just twist this, it will hold it into place.This is an open unit.

It can be hooked up and tested before your sidewalls are sealed. The unit is very small and lightweight for an easy fit in the RV's cabinet. Total weight on the unit is about 24 pounds. It is CSA certified, made in the USA.Few specs on it. It's 120 volts AC electrical connection. Wattage is 1400 watts. Heating capacity is 10,000 BTUs. Few dimensions on this. I want to give you the door dimension is going to be right at 18" wide, and the height on the door is 17 3/4". If we go ahead and drop the door again, just to measure the unit itself, water heater width wise inside is going to be right at 16", height is going to be right at 15 1/2" tall, and total depth is right at 20 and 7/8" deep. Again, the tank capacity is 10 gallons. And again, we can just flip our door up, close it, and then pull this out and just twist it. It'll hold it into place and there as everybody can see, your pilot light.It does come with a nice set of detailed instructions on how to install everything. But that should do it on the review of the Atwood RV 10,000 BTU Gas and Electric Water Heater with the Automatic Pilot and a 10 gallon tank.

While staying in Las Vegas our 18 year old water heater failed. I usually do this type of repair or replacement myself. The Atwood model we have was no longer available. I called Dometic for a replacement part number and actually received some incorrect information. Decided to go to Tucson where I have a workshop and other accommodations and take my time replacing the water heater as the controls on the replacement are different and there was some water damage done to the coach. Priced the water heater in Tucson and E-Trailer beat the best price by around $300. Got it at E-trailer free shipping no tax. Talked to Troy at E-trailer several times with some questions about mounting and size, he was very helpful. I ordered it on a Saturday and he made sure it was shipped first thing Monday Morning, He quoted delivery on Thursday and I received it on Thursday. He emailed me when he go delivery conformation and followed up later to see if I was satisfied. Installation took a bit longer than normal as I had some water damage to repair and the controls are different. The water heater came with a new switch panel but I wanted to incorporate our existing controls. I would use E-Trailer in the future and I was very satisfied with service provided by Troy 471938

Ask the Experts about this Atwood RV Water Heaters
Do you have a question about this RV Water Heater?


  • Atwood RV Water Heater with Electric Operation That Matches 12-1/2 x 16 x 18 Dimensions
  • We do have Atwood RV water heaters in both gas-only and gas/AC-electric types but we do not have an electric-only water heater. The standard gas/AC-electric unit that matches your 12-1/2 x 16 x 18 dimensions is the 6-gallon # AT96117. Model # AT96163 is similar but also includes a heat exchanger. If you want to operate one of these water heaters with only 120-volt AC electric power that is certainly possible.

  • What is Advantage of Electric Plus Gas RV Water Heater Over Just Gas
  • The Atwood water heater part # AT94022 is a great option for you as it has an electric element that helps heat the water as well as a gas heating element. The electric element allows the water to heat up a bit quicker so it is a nice option that allows this to produce up to 20 gallons of hot water per hour. Strictly gas water heaters like the part # AT94191 that has the same 10 gallon tank can produce up to 13-1/2 gallons of hot water per hour.

  • Replacement 10 Gallon Water Heater for Model G10B
  • The G10B is an older 10 gallon unit, as you mentioned, and to replace it I recommend the Atwood RV Water Heater # AT94022. This water heater uses an automatic gas pilot with an electric heating element to produce up to 20 gallons of hot water per hour and is thermostatically controlled. It measures 16" tall x 15-1/2" wide x 20-7/8" deep and is made in the USA.

  • How to Install the On/Off Switch Panel for Atwood Gas and Electric Water Heaters Part # AT91230
  • I have attached the wiring diagram for the Replacement Double-Panel On/Off Switch for Atwood Gas and Electric Combination Water Heaters part # AT91230. The installation will be very simply with only 5 connections needed. There will be three terminals that go to the water heater (orange, blue, white), one terminal that goes to a 12 volt power source, and one terminal that goes to a ground. In order to make these connections I recommend using four of the Female Spade Terminal Quick-Disconnect...

  • Replacement Electrical Heating Element for Atwood Gas/Electric RV Water Heater AT94022
  • If your Atwood Gas and Electric RV Water Heater # AT94022 operates properly with gas but not with electrical power then you are probably correct that the thermostat is okay. If the thermostat were bad this would affect both modes of operation. It is more likely that the electrical heating element is worn and needs to be replaced with Atwood part # AT92249. To find the location of the element you can just trace the two power wires. The photo I linked for you shows the location of the...

  • Location of Electric Heating Element in Atwood 10-Gallon RV Water Heater 91160
  • RV water heater replacement heating elements such as Atwood part # AT92249 and the similar items shown on the linked page usually install near the bottom of the water tank so that they are fully immersed. On the Atwood water heater 91160 the electric heating element will be behind the gas line assembly. You can refer to the linked photo. This part needs to be loosened and shifted out of the way in order to unscrew the old heating element. My Atwood contact confirmed that you will want...

  • Replacement for Atwood 10-Gallon Gas and Electric Water Heater GC10A-3E
  • Based on my research, the GC10A-3E is a 10-gallon Atwood gas and electric water heater. For a replacement I recommend the Atwood RV Water Heater # AT94022, which is also a 10 gallon gas and electric water heater. This unit can produce a sizable 20 gallons of hot water per hour, is made in the USA and comes with a 2-year warranty. As a note, I did want to mention we do recommend always having a qualified professional install a water heater.

  • Terminals Functions for the Atwood Replacement Double-Panel On/Off Switch
  • I wish that I could verify what function each of your wires carry but unfortunately if your wires are different colors then I won't be able to verify that right off-hand. If the Double-Panel On/Off Switch # AT91230 is exactly the same as what you have now though and you have either the Atwood RV Water Heater part # AT96163, part # AT94022, or part # AT94023 you should be able to just disconnect each wire and connect them to the exact same terminal on this replacement switch. Aside from...

  • Replacement Atwood Water Heater for Model GC10A-4E
  • I spoke to my contact at Dometic (who bought out the water heaters from Atwood) and the Water Heater # AT94022 is the exact same one that you mentioned so it is the correct replacement and will have the same wiring connections.

  • What is Difference Between Atwood Water Heaters # AT94022 and # AT96117
  • The Atwood RV Water Heater part # AT94022 has a larger 10 gallon tank and higher BTU rating of 10,000 whereas the part # AT96117 has an 8,800 BTU rating and a 6 gallon tank. The larger tank with a higher rating means you'll have access to more warmer water than the other one.

  • Heating Element for Atwood Water Heater
  • The Atwood RV Water Heater # AT94022 you referenced is designed to be used with a 1400 watt heating element # AT92249 and while you could use a lower watt element, it is not recommended, nor is there a lower-rated replacement that is confirmed to fit. Additionally, installing a lower wattage element will almost certainly void the warranty of the # AT94022 so it is something that you will want to avoid doing.

  • Switch Included with the Atwood RV Water Heater # AT94022

  • Replacement Electric Heating Element For The Atwood 94022 Water Heater
  • Yes, the Replacement Electric Heating Element for Atwood Water Heaters part # AT92249 is designed to replace the existing water heater element on the Atwood RV Water Heater part # AT94022. As these elements can be very difficult to remove, you will want to soak the threads in a penetrating oil first. Once soaked, you can then begin to remove the element. If all else fails, heat will be your best option. You will also want to use a bit of teflon tape or thread sealer when re-installing.

  • Compatibility of 10 Gallon Water Heater in 1994 Fleetwood Pace Arrow
  • You can add a larger water heater as long as your space allows. The Atwood # AT94022 water heater dimensions are 16" tall x 15-1/2" wide x 20-7/8" deep. The door dimensions are 17-3/4" tall x 18" wide. As long as these dimensions allow you the room, you can absolutely upgrade to a 10 gallon water heater in your 1994 Fleetwood Pace Arrow. You will want to check to ensure your electrical and gas systems can deliver the power for the larger system, as those may or may not need to be upgraded...

  • Replacement Water Heater Option for 1974 Winnebago M-22 Travel Trailer
  • Best option would be to measure the dimensions of the area to see what water heater would fit best. Our 6 gallon gas and electric Atwood Water heater part # AT96117 measures 12-1/2" tall x 16" wide x 18" deep. If you have the room for it this would work great.

  • Flow Rating for Ultra Faucets Shower Head # 277-000008
  • I checked with Ultra Faucets and for the Shower Head part # 277-000008 is rated for 2.5 gallons per minute. So with a 5 gallon water heater you'd have 2 minutes of hot water. The only way to really increase the time of having hot water would be to go with a larger hot water heater otherwise you'd have to be constantly needing to shut the water off while in the shower to preserve it. We have the 10 gallon water heater part # AT94022 which uses gas and an internal electric heating element...

  • Troubleshooting DSI Fault Light on Atwood Water Heater GC10A-4E
  • I spoke with my contact at Dometic (who took on the Atwood water heaters) and they said that the DSI fault light on the switch for your Atwood RV Water Heater # AT94022 (GC10A-4E) will only come on for two reasons. The first reason is that the water heater has attempted to ignite and failed, while the second reason is that the ECO has become an open circuit. They said to check for continuity across ECO when your light comes on to see if that is the problem. Let me know if you are...

  • Does Atwood 10 Gallon RV Electric and/or Gas Water Heater Use Anode Rod?
  • The Atwood RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - 10 Gal Tank # AT94022 does not use an anode rod. The manufacturer uses a comparable if not superior protection by using a clad aluminum lining that protects against corrosion and does not require yearly maintenance like an anode rod.

  • Atwood GC10A-4E Water Heater is Shutting Off After 5 Minutes
  • I reached out to my contact at Atwood who said there are a few different reasons why your GC10A-4E Atwood water heater, like part # AT94022, is shutting off after 5 minutes. She said that it is either reaching the set temperature, that the tank is empty of water, or that it is reaching temperatures excessive of 180 degrees Fahrenheit and the ECO (emergency cut off) is kicking in. If your water isn't reaching the set temperature then try making sure that you have enough water for the...

  • Troubleshooting Atwood RV Water Heater 94022
  • Since the Dometic Atwood Gas/120V RV Water Heaters like # AT94022 require professional installation I recommend checking with the shop that installed it. When you say the water gets cool fast do you mean stored hot water does not stay hot or do you mean that you run out of hot water quickly? This unit is rated to provide 20-gallons of hot water per hour. It also has a high-temperature limit switch that automatically shuts the unit off to prevent overheating. This feature may be malfunctioning...

  • Can a Motorcycle Battery Be Used With a Gas/Electric RV Water Heater
  • Yes, you can use a motorcycle battery to power the thermostat and ignitor on an RV water heater such as the Atwood RV Water Heater part # AT96163 for 6 gallon or part # AT94022 for 10 gallon. However, you will need to make sure the motorcycle battery is 12 VDC as some can also be 6 VDC which you could still use but would need to use two and wire them in series. Please note that the unit would still need to have access to 120 VAC as well as natural gas in order to function properly. The...

  • Compatibility of Atwood RV Gas and Electric Water Heater with 12V Battery
  • The Atwood RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - 10 Gal Tank # AT94022 requires 120V for both the direct spark ignition and the heating element with thermostat. It will not run on 12V power directly, so you will either need shore power or a power inverter for your 12V battery to give you the 120V output. If you need the power inverter it needs to be capable of 1400 watts or more like # 34279950 or # 34279458 to operate if you don't already...

  • Fuse Blows when Switch is Turned on for Atwood GC10A-4E Water Heater
  • Check for any places where the wiring or the switch on your Atwood Water Heater GC10-A-4E (same as part # AT94022) is damaged. Since a blown fuse means excessive power draw this means that there is a short somewhere whether it is on the wiring or the switch. Please note that the installation and service must be performed by a qualified installer, service agency, or gas supplier so it would be better to have someone certified do the troubleshooting.

Therefore, the only option we can offer you is a new water heater, the Atwood RV Water Heater part # AT94022 which is an exact replacement so the wiring will all be the same.
