So wanted to get some input on this , I notice on electric , there is hot water .. but it only last for a short time , probably less than a min then it goes luke warm. What could that be attributed to ? Heating Element ? .. The hot water come out very hot for 20 to 30 seconds or so then just dies out .. so not sure if that is the heating element or something else. No red light on pump 3 . so just wondering where do i need to start looking at on this. On burner , works fine of course has to heat up first to get the water back up to temp
thoughts ?

Thanks

Do you have any where in the coach that shows your amp draw. If so, see what your amps are then turn on the electric element. The amps on one of the legs should increase about 8 amps. If you don't see an increase in the amps you need to replace the element. I'm assuming you have the breaker on.

Electric only is good for short duration hot water. Turn your burner on for sustained hot water. Typical day use of washing hands and such are fine for electric. Shower, burner for sure. This has been my experience.

I regularly take full, hot, showers with electric only and lots of hot water to spare. I'd check the "summer" or "stir" circulation pump as it's probably not running.

We use electric hot water for day use. I use electric for a shower but I have to conserve. I lower the flow rate and turn the water off after I get wet while I am using soap. Then turn it back on to rinse. If I want a longer hot shower I use the diesel burner.

My wife uses the diesel burner when showering 100%.

The electric hot water supply is limited.

What is the ground water temperature where you are currently located? If it is not warm, burner help will be required for longer hot showers.
Stir pump functioning would be something to check in addition to the light.
80* weather, electric will give us two showers back to back, 50* not possible.

About 2 years ago I wanted more hot water production on AC current. I found that Aquahot uses 2 2000 watt electric elements in the 600d and the 450d uses a 1650 watt element. I purchased a 2000 element from a 600d parts place and installed it in my 450d. It has made a noticeable difference and has been working great ever since I installed it. Just an FYI

but if it was the element , would it not heat the water in electric mode ? i have hot water but its not a long time, as when i got the coach three years ago we could take a hot shower on the electric only before it went luke warm. I can check the inverters screen and turn off the electric to see what amps i am drawing before and after.

If the stir pump was not working would i not have hot water in electric mode ? I have green light on pump 3 when it is running and can hear the pump running. the pump was replace 3 years ago when i pick up the coach at NIRVC ,.,but was disappointed that i came to find out they put in an OASIS pump., but since then it been working up until now where the hot water doesn't last as long as initally on electric,, washing dishes and or washing hands , i should have enough water to last through a few pots

Good to know! Still getting to know our coach. Last trip it was 50s and we could shower on electric but it certainly wasn't a hot one for the duration. Nice to know that's normal.

I agree with Chuck. I think if your overnights have been in the forties or so, ground water is still pretty cold.
If you don’t get more hot water for longer durations on electric, then you might want to have it looked at.

Where did you come up with that?

I've run a Aqua Hot 450D for close to 10yrs, and with the 1650W element on, your looking at about 14amps!

ECVB · 03-16-2022, 10:06 PM

looking at the service docs..

Using a digital clamp-meter, verify the electric element’s amp draw is between 11.2 to 13 amps.

Using an ohmmeter, check the electric heating element for the proper ohms. The Ohms reading
should be between 8.5 - 9.5 ohms.
If the ohms reading is not between 8.5 - 9.5 ohms
follow the instructions in this section to replace the
electric heating element.
