Do any of you have a heat pump on your RV? That would also be an interesting comparison.

Many more heating options out there. What about Truma systems? My outside vent produces almost no heat and I get hot water too. While not scientific my 10 gallon propane tank seems to last forever. Then what about heat pumps in rooftop AC units? How about diesel burners like Aquahot?

Different subject, Mike. Is it safe to use multi-source battery charging at the same time? I have a truck camper with 950 watts of solar, 736 AH of lithium battery, a 50 am dc to dc charger, & a Champion 2500 watt dual fuel generator. I have run all 4 sources of charging at the same time before, (solar panels, dc to dc charger, 7 pin truck bed plug, & generator), but have wondered if there is any possible conflict with that many sources of power going into the batteries at the same time. My Expion 360 batteries can easily handle the total amperage of 70-80 amps, but I'm more concerned about cross feed or any other potential conflict between the 4 sources.

RV heating systems like the Alde are a different animal. The heat exchanger is simultaneously heating your water as well as charging the transfer fluid that is circulated for space heating. One input = two outputs.

We have an Aqua hot that uses diesel fuel for heating. I have never seen any comparison to electric heaters.

The Aqua Hot does have one electric element (that can't keep up under load), but my question would be diesel burn versus electric heater used inside the coach.

In California, electricity costs way more than $0.18 per kWhr, (est. 2-4x or up to $.6 per kWhr) and propane costs more than $3 per gallon, (est. $4-5 per gallon) so it’s cheaper to heat with propane unless you don’t pay anything extra for electricity as is the case when you stay RV parks that don’t charge for electricity.
