AC1 and AC2

Were out RVing in ND later than we should be. Its snowing. The state park that were in only has 30 amp service. Can I run the furnace on AC1 and AC2 or am I going to have to run the diesel burner to keep warm tonight. Temp at about 30 degrees.

You mean the heat pumps?

Heat pumps will only work to about 46 degrees or above.

And you have to turn on your diesel burner to get the furnace to work. AC 1 and AC 11 are for the hot water only.

Each element is 1500 watts. Both on is 3000 watts or 25 amps at 120 volts. That doesn't leave anything for charging batteries, lights, refrigerator...

When I am on 30 Amps and it is cold I use AC1 and the oil burner. You can try it with just AC1 but the fans and pumps will run all the time. The oil burner will keep you toasty warm. We like the hydronic heat and don't use the heat pumps.

We unfortunately do not have the electric floor heat. That may be the best choice with the oil burner assisting.

In our coach, the Oasis AC1 and AC2 elements will provide some heat in addition to heating water, but at 30 degrees, I would be running the diesel burner. We are still at our Western Montana place and the temps are dipping well into the 30s at night, so we're running the diesel burner.

We did discover last night that leaving the heated floors on the "4" setting (just comfortably warm on the feet) overnight kept the coach at 62-63 degrees all night. That's about where we like it for sleeping anyway. Not sure if your coach has electric floor heat, but if it does, that's another option...though you'll have to manage your current draw with a 30A service.

I want to correct myself about the AC1 and AC2. I was told that was for water in the summer mainly. To use the burner for heat. I believe you can use them. For heat after reading a couple of other posts. I've only had this coach since February so I'm still in the learning faze.

Not on the newer coaches. We heat all the time with the Oasis on electric only.

Some misinformation...you can use AC1 and AC2 for furnace heat. The problem when on 30amp, you'll be pretty much limited to AC1. Overnight, when you have everything turned off, you might get away with running AC2. Your coach will shut down AC2 if you exceed the 30amps.

With that said, when on 30amp, I leave AC1 on and turn the diesel on as backup. If AC1 can't keep up the diesel burner will come on. This way I use electricity as much as possible and run the burner if more heat is needed.

Now here's another way to cheat a little. Typically, your the 30amp shore post has a second 15amp plug. Generally, these are on a separate circuit. If you have neighbors close by and don't want to blast them all night with the Oasis, you can run an extension cord inside the coach and plug an electric heater into it for the bedroom or main cabin.

Not to high jack this thread, but with all the talk about cold weather operation and the Oasis operation I thought of a question for you seasoned operators. On our Ventana we have the Hot Water by the generator valve and I was wondering, what keeps it from freezing in cold weather. The Oasis is supposed to heat the basement - automatically - but the generator compartment isn't closed. I was told to be safe run some pink stuff through that valve to essentially 'winterize' that outlet.

Real life opinions and experience would be greatly appreciated.

On ours, there is a shut-off valve for the front water line located in the forward cargo bay on the passenger side. Shut the valve off, then open the faucet in front and let the line drain.

I will have to check that bay, however our valve is on the drivers side. I any Ventana folks out there now where the shut off might be I would appreciate it.

Sorry...mine is on the drivers side too. And, the valve is in the forward cargo bay on the DRIVER'S side. Don't know what I was thinking.
