Excellent question, and tankless water heaters like those from Furrion or Fogatti will actually use less propane than their tank counterparts. The reason for that is the tankless heaters only use propane as the water is being used, so if you hop in for a quick shower, for example, propane will only be used when you have the hot water on. Tank heaters, on the other hand, heat the whole tank of water (and take much longer to heat), so even if you don't use the whole tank of hot water with... view full answer...
Yes, all RV tankless water heaters such as my preferred model, the Excel RV Tankless Water Heater, # EX93FR are designed for liquid propane (LP). They will have an electric source only for the purpose of providing ignition spark. view full answer...
RV water heaters like your GC10A-3E # DMC74FR require both gas and electric to function. There is no way to turn one fuel source off and still have the unit produce hot water. The electric side controls the functions of the water heater while the gas is the fuel source for heating the water.
However, you could go to the tankless side and getting a Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 18" x 18" Door # FR68SR. Or ther Furrion RV Tankless Water Heater -... view full answer...
No, there is no need for an anode rod in water heaters such as your Atwood and the Dometic RV Water Heater, # DMC74FR. The manufacturer uses a clad aluminum lining that protects against corrosion eliminating the need for an anode rod. view full answer...
Tank heaters like the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163 are not compatible with 24volt applications and will only operate properly in a 12v system. view full answer...
The Fogatti Tankless Water Heater # LSB44FR maintenance section lists that you should drain the RV regularly flush the heat exchanger with an RV rated descaling solvent. They're very loose on their verbiage on "regularly" so at minimum you should do it once a season. to get the solvent through the water heater you would need to dump it into your gravity fill tank and run your water pump to pressurize the system and then run your hot water to pull it through the water heater. view full answer...
The Dometic RV Water Heater # DMC74FR uses an electric heating element to assist the flue tube to heat the water quicker. A double-panel switch # AT91230 can be purchased separately to allow you to power the electric and gas components on and off individually. view full answer...
Some items just can't handle the power of propane.
**Excel RV Tankless Water Heater - Gas - Electric Ignition - Vent Free - 38,000 Btu # EX93FR.
But the Excel Tankless can. You are 100% correct, the heat source for the Excel RV Tankless water heater is indeed Liquid Petroleum Gas(LPG), AKA Propane. view full answer...
The reason is that a holding tank heater pad like the # 277-000163 you've looked at isn't designed to heat a battery. It's designed to heat a large 29-40 gallon tank, not a much smaller battery. A thermal battery heater would usually wrap around all 4 edges of the battery and gently heat it from all sides, while the tank heater isn't meant to be folded or wrapped around anything.
You'd be better off using an actual battery heater, like one of the ones I've linked for you. Using the product... view full answer...
I have attached some info below regarding the gas consumption of the Excel RV Tankless Water Heater part # EX93FR.
A person can take 133 - 5 minute showers - with a 20lb tank
A family of 4 can take 5 minute showers for a month.
Calculation
1 gallon of Liquid Propane Gas (LPG) converts to 36.39 cubic feet of Propane Gas , there are 4.6 gallons of Propane in a 20lb bottle.
167.4 cubic feet of vaporized propane in a 20lb bottle.
There are 2,523 BTUH in one cubic foot of propane

Being that the Excel RV Tankless On-Demand Water Heater, # EX93FR is tankless, the need to drain that component is non-existent. However, there may still be water in the lines and valves that needs to be addressed. I suggest that you remove power to the water heater, close off the water supply inlet and disconnect the outlet water line allowing any water that may remain inside the system to drain. Use compressed air to blow out any remaining water from the lines. view full answer...
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. view full answer...
There are water heaters that you can use to replace the Atwood GC6A-7, since they are no longer in business, a direct replacement isn't available. As such, the best option I can recommend is to upgrade to a tankless heater, the Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 16" x 16" Door # FR98SR. view full answer...
The hot water lines in your trailer are separate from the cold water lines so if someone used the cold water in the kitchen while someone else was taking a hot shower you wouldn't have any interruption with the water temperature. Now if multiple faucets are using hot water at the same time the demand on the Fogatti RV Tankless Water Heater # LSB44FR would be greater and could possibly exceed the capabilities of the water heater, with the result being lukewarm to cold water. view full answer...
A water heater like the Dometic RV Water Heater # DMC74FR that has a DSI system will not require additional wiring for just the DSI. A DSI and non DSI water heater will have 12 volt power that goes to operate the thermostats and DSI board for those models. This particular water heater does have a 120 volt electric heating element as well as control switch for both. You would need the additional wiring for the control switches and 120 volt connection if you do not already have them. view full answer...
