Does the Oasis Have a Priority ?

[VACMAN]

This weekend it was a little nippy. The furnace was on and heating the coach. The DW was taking a shower and Stated she had no hot water. My question is: Does the Oasis have a priority? I know at home I have hot water heat, and it the floor is being heated it will not heat hot water for the storage. Also she took the shower soon after we had stopped from a 50 mile run. A friend stated that the water should have been hot from the run?

VACMAN - was the diesel burner on or just the 110v element?

The diesel burner in my experience gives unlimited hot water even with the furnace running. The 110v element just doesn't have to capacity to do both.

I too have noticed that after traveling a long distance, when I switch the diesel burner on after setting up camp, it fires up nearly immediately, even tho the fluid in the lines should already be hot.

AquaHot HAS a priority - the other way around from your description. Domestic hot water demand shuts down heat. Seems I recall that Oasis does this as well.

But, you stated the burner was on. Seems what happened to you is that it failed to light causing the domestic hot water to go cool. Even if the priority was reversed (heat trumps domestic) and it was just a little nippy, the heat demand should not have totally killed the domestic hot. Something failed to light.

Just to further clarify, if you stopped after a drive, had the diesel burner OFF and NO shore/genset power (even with with the 110v element switch ON) then you WILL run out of hot water rather pronto. Without the diesel burner on and/or the 110v elements actually powered and on, the engine will 1) need to remain running to heat the hot water being used in the shower and 2) the engine alone will NOT provide sufficient heat to heat a continuous hot water demand like a shower.

Neither Oasis or AquaHot actually heat a bunch of water in a tank like a traditional stix-n-brix hot water tank. Rather, these hydronic systems heat the water on the fly as it is used and therefore must have a heat source (diesel, 110v, or engine) to provide the heat while hot water is demanded.

UPDATE::: The Oasis failed again. After getting home I called Oasis Mfg. The tech ran me thru a couple of tests, and found out the compressor was not working. I am still under warranty, so they are sending me a new Compressor out at NC. I must say they were very nice and very helpfull. I am so glad I have an Oasis system. It sure is nice to have a Phone # you can call and have someone glad to help you..VACMAN

On their web site, they even have a video on how to change it out.
Pretty neat

I had the Oasis compressor fail on my brand new Essex during PDI and Newmar promptly replaced it. Two months later, the second compressor failed. It would fire up and immediately flame-out. I was parked in Naples, so I just switched over to 110 power and took short showers for a week or two. The day before I was scheduled to take it to North Trail to have it repaired, the darned thing started working again. I suspect this is going to be an ongoing issue with the Oasis.
