Oasis forced air heating?

Just picked up new 2022 Dutch Star 4326.

I think I have 3 heat sources:

1. heated floor (controlled at light panels, front/back, and has hi/low setting).
2. roof heat pumps (controlled at driver's control center, set temp and it goes).
3. Oasis heat

The Oasis, as I understand it, will heat water from the engine, diesel burner, or 1/2 AC heaters.

I had thought there was a way to use that hot water to heat the coach also, with some type of forced air system that ran air over hot water pipes to provide a furnace like experience.

I don't see a way to do that though? Did I just imagine this feature?

Yes, it will be used as forced air.

On your air controls it will be called furnace, and is available on zones 1 and 3.

Correct. When the furnace source is chosen, and the oasis is turned on burner or electric that will
Provide hydronic heating through the heat exchangers. It move the hot coolant through the registers and fans force the heat out.

Oasis forced air heating?

The vents for the forced air are very well hidden and camouflaged.

Here are a couple of examples.

If you look behind the vents in the coach, there are small radiators. If you get down on your knees and look at the rear of the wet bay, you'll see one of them, it's exposed in there. They heat up and there is a small blower behind them.

You also have one of the heaters under the drawers at the center of the dash. It is operated when the furnace is on, and you TURN ON the dash switch that says heater. It won't operate otherwise.

Your engine will heat the system while driving, but you can't heat the engine (for cold starts) unless you add another switch and pump. The next level up Mountain Air and above are capable of that without additional changes.

With all that said, we've camped in 15 -20-degree weather several times now and all that was needed were the heated floors. They kept the coach very comfy. They need to be turned on early, before it gets too cold and on warmer days, turned off in the morning or the coach will get too hot.

Lastly, hear is something I wrote about Oasis heating that really explains when you need to use the various levels of the system, AC 1, AC 2 or diesel burner.

Did you just get in your new rig and drive off with no guidance? Can't believe your dealer didn't walk you through some of this basic stuff.

I have talked with many owners that went thru the same delivery process I did, and walked away without the same understanding.

Depending on prior ownership, you may not understand the purpose of the training you received until you know how to apply it.

This is the core reason I changed the policies for how new hires are trained at my company. We teach them how to find information and more importantly how do identify the proper time to ask for help before continuing. This is emphasized at all levels.

My philosophy: Better to ask a dumb question than perform an action that will prove you are dumb...and potentially get you a position in line at the unemployment agency.

Thanks, this clears it up. Found all the right settings.

As to my delivery experience... I've been RV'ing for 10+ years, and came in with a long check list of items to cover (this question was on my list)... The delivery specialist walked through a ton of stuff, but in the 3h of discussion, we got through maybe half my list. I let myself get distracted with some larger problems, and then I was late for a meeting.

I will say that for many of the systems, I already had researched more than the delivery specialist, I don't think they sell a ton of Dutch Stars (or Newmar in general) at the place I bought from, it looked like the bulk of their business was travel trailers.

As I realized their level of expertise, I shifted to trying to get the core problems (broken things, etc.) that I needed them to repair, and I figured I could research my way out of most questions.
