No Propane!

Seriously, I will not be using propane in my conversion. I want to use a hydronic heating system to heat the coach, the water, and preheat the engine in cold climates. I could go on an on about the advantages of this fairly new approach to heating air and water in an RV. But I'd like to hear from you.

Has anyone installed a hydronic system in their skoolie?

Yes, this has been discussed before. More than once.

Solar water systems work great if designed and controlled properly and the correct safeties in place.
Without propane a diesel fired system separate from the buses heating,motor running and fuel tank would work for back up.
Why NO PROPANE?

If you are concerned about fire...consider this... the vast majority of RV fire are electrical...not propane.

I'm going to build a kind of survivalist bus (zombie apocalypse). Propane will not be available at all if civilization crumbles. But fantastical ideas off the table, I've had times when locating propane was not easy. It isn't something that can be produced with another on-hand substance (like biodiesel from cooking oil) or something that is renewable (like solar). It is dangerous and would multiply any other issue (like an electrical fire). Just the fumes from a burner left on (or turned on by the cat) would be a big problem.

None of these issues exist in the hydronic system. On-demand hot water...so nice. Quiet heater in the coach...not a bad thing. Able to start up when the temps are arctic...very nice.

Bottom line: I have my reasons. We can debate them, if you wish. Or, I can elaborate more, if you want. I just don't want an inferior system in my rig. A hydronic system will accomplish everything I desire and more. Propane is more of a liability than I care to endure.

I'd like to hear from others who have built such a system.

If some of you are tired of having this discussion, please click to something more appealing to you. I'm not here to bore you, just learn.

Blessings

I'd like to see actual cases of issues that happened in converted buses due to the liability of propane. I bet they are few and far between. If done correctly it is very safe. Done incorrectly anything you do could potentially be dangerous. How are you powering your hydronic system? Most RV fires are from electrical issues

Someone I know had his 5th Wheel burn to the ground because the cat started the gas range somehow.

If used correctly, electricity doesn't start fires either. However, the other safety issue is the gas itself is toxic. And you're right, anything can be dangerous if you're a dunce. But safety is not the only issue. The issues are:
* Supply vs demand (I've had to go without or travel far to find propane when I wasn't paying attention to the tanks). Renewable energy is key here.
* Risk of fire and inhalation
* Noise level of propane heater (not too big of a deal)
* Water heater tank capacity vs on-demand (kind of a big deal)

I'm looking into powering the system with electricity (shore and solar) as well as diesel. Power consumption of DC is nominal (I don't have the stats right now). While running the engine, the hydronic fluid is warmed by it. It is antifreeze, after all.

Thanks for the input.

I'm trying to justify the use of it on mine. My hydronic flooring I want warm while the engine isn't running. My On Demand water heater will be propane fueled as well as stove and possibly fridge. Plans on a 60gallon tank, should last more than needed. Propane generator to keep fuel sources to a minimum.
