Oasis Hot Water

We are having a problem with our Oasis Hot Water Heater.  The hoses and water in the tank are hot but we are not able to get hot water to our faucets in the coach.  We spoke to the manufacture last week and he said it was probably the mixing valve so we replaced it today and we still are not getting hot water in the coach.  The heaters are coming on saying it is heating the water and our floor heating is working.  Does anyone have any idea what it might be or encountered the same issue? Any help would be greatly appreciated.  Thanks.

I can't offer anything specific on the Oasis. When you say the floor heat or you talking about the tile heat or the floor air registers?

I have the Oasis in my coach and can answer questions. But I have not had any issues with mine, yet! Keep my fingers crossed!

I fixed that same problem on SOB so I can't attest to the type of water heater, but I was told it is a common problem.
There is a $7.00 valve in the supply line, just before the water heater tank. It is a "one-way" valve, spring loaded. When it breaks no cold water can get into the tank to push the hot water out. The valve is to prevent the hot water  backflowing and end up heating the cold water in the supply line.
Unfortunately the valve may only be accessible by getting underneath the coach, removing an access cover, reaching up into a cluster of dirty, diesel soot covered hoses back by the engine. At least this was the case with the SOB I fixed.
The valve we purchased at Camping World. I learned that this is a common problem with coaches equipped with this valve so my friend bought a spare.
You may not have this valve so check with others first in order to find out.

Thanks for the replies.  Our Oasis is a CH-50.  The heat we were getting from the floor was the registers not heated tile. After hours of researching and looking at the manual we called the manufacturer again this morning.  After going through all the possibilities again with him he stated we had a check valve on our Summer Loop of the heating module.  He told us to hit it to see if it would possibly dislodge any debris that may have been stuck in there.  After hitting the valve we found that it was obstructed with calcium deposits from where we stayed this summer.  We were able to dislodge the deposits and now have plenty of hot water.
