Title: Aqua hot
Post by: lavocat on October 21, 2013, 02:20:58 pm
Any problem running the AQ on just diesel without electric burners on?  Have only a 30 amp connection and need to conserve. What you think Rudy ?

Semi related.  After I winterize - including the aqua hot - are there any issues with using the aqua hot on electric and/or diesel for heating the coach?

Thanks for the tread...

We will be staying in Tucson for the winter, which only on occasion get below freezing, but do not have power to the coach. Do have 150 watts of solar and could add another 300 watts if I can find the time.. Coach is only a couple blocks away so I could check voltage in the early morning after a cold nite. 

Will I be ok leaving diesel aqua on and not run down the batteries?  I could also leave auto generator on.

We will be using the coach on occasion during the winter.  Of course, have drained black tank, grey tank, emptied water tank and drained as much as possible. Will add RV antifreeze to drains.

Sorry for all the questions, but this will be the first time we winterize since we usually hide from any cold weather.

Thanks in advance..

When you winterize the water system you are replacing water with potable antifreeze.  The Aquahot heats its own antifreeze solution that transfers heat to the heat exchangers, the hot water tank (and the engine if you turn that switch on).  When you drive the engine heats the same fluid.  So once winterized running the Aquahot on diesel or electric to heat the coach or the engine works fine.  The electric heating element in the Aquahot will provide enough heat down to about 40°, maybe a bit less.  At that point it can't keep up with the heat demand and the fans in the heat exchangers and the Aquahot pumps will run almost continuously. Not good for the batteries.

We leave the diesel Aquahot on all day.  Once the system is heated up it only needs to keep it hot by running every once in a while.  It will use some battery but not too much.  We turn the heat down but not off at night or if we are not in the coach.  You should be OK overnight running the Aquahot.  We get by in the late Fall with a couple hours of generator time.  Be warm.

Just a reminder that when you leave systems running unsupervised one is asking for trouble (such as when coach is in storage). The most reliable way to winterize is to evacuate all liquids that can freeze and add RV antifreeze to those water lines. Disconnect batteries (yes I know some year coaches this can be a challenge).

That's a good point,  when the coach is in storage, everything is off including the 12v disconnect switch.  It is plugged in most of the time.

When we are camping and away from the coach for any several hours we usually turn the AH off.

Thanks all - glad to hear I can turn up the heat!

I should have mentioned that I only need to run the aqua hot on diesel for a night or two of winterized camping before the coach gets to its final destination which is climate controlled.

Do it all the time when boondocking. Cheers Karl
