The Bucket List

LoL

Somehow I figured they would be sideways.

Thanks for the photos of your home system. For the bus, I went with the Camplux 2.6GPM heater:



https://camplux.com/camplux-10l-2-64...-water-heater/


The website mentions it can be installed inside with proper venting. I haven't gotten as far as reading the manual: that is on my weekend list of things to do. But, while at work with my mind wandering, I was trying to think of how you would vent it on the bus itself without something sticking way too far outside of the bus? Mine looks pretty much like 01marc's does, so I figured this is might be a good time to get some thoughts on the matter.

Since the motor temps could easily burn you I think you would need a tempering valve. The pressure wouldn't be an issue on the radiant / hot water side because they can be different pressures on each side of the heat ex-changer. The outlying questions would be would you pull too much heat out of the coolant line and the engine wouldn't be able to keep itself warm enough, and does the engine produce enough heat for on-demand heater levels of water temp increases. A side-effect would be you could use your propane heater as an engine block heater on cold days if you added an additional circulator to the bus coolant loop (my bus is like yours in that I have a seperate coolant pump already as well, just have to power it off the house batteries).

You quoted me so just a little confused. I don't have a propane heater. My intention is diesel everything. Diesel water heater, diesel heat, diesel stove. My tank is only a 65 gallon but the plan is to add (in addition) a 100 gallon tank aft of the 65 gallon and plumb them together. I don't like stopping for fuel. And if I'm on short trips in good weather, the 100 would be all but empty to save the 700 something lbs.

I'd probably go with a 45° angle raked backwards just so it doesn't try to back pressure while driving down the road at 65 mph. Would it hurt anything? Would it actually back pressure? I dunno but it just looks right.

Sorry for the confusion @Brewerbob, I just really liked your idea of trying to pull domestic hot / heat in-floor off the bus engine. You could just replace the propane heater with a diesel one, the diagram was really more of me brainstorming for myself

Are you describing something like this?

No worries and I thought that was the case. Just making sure you weren't talking to someone else as well.


It's the valving, temping, and exchanging that I'm worried about when using coolant with an exchanger. With the bus running down the road, is the floor going to get to 170° that the engine block see? That'll keep people from wandering around while the bus is in motion. I don't think I'll be taking a shower while in motion so I can use the diesel heater for floor and shower or just shower when parked. I might be able to shower with the coolant if I get to it soon enough after parking.

I will want to use the radiant to warm the engine when boondocking in the cold. The bus has a block heater but if I can do it without using house batteries, all the better.

Don't we have a water heater thread this could be pursued in?

Looking at the side of the bus, as it exits the bus. Rotate the 90° elbow 45° diagonally so it is neither up and down nor fore and aft. Should keep it from whistling like a soda bottle as well.

[Brewerbob]

Between 3 o'clock and 6 o'clock. At 6 and 12 it'll whistle. From 9 thru 12 to 3, you'll get water in it. From 6 to 12, you'll get a breeze up your skirt.

OK, I get what you are saying now. Thanks!



I won't discuss this anymore in this thread - I'll find a water heater thread for any other questions. But thanks again.

Very nice setup you have there Firepuncher Excellent job!

Bob,

Have you lived with a diesel cook stove before? If not, I would suggest visiting someone who has one and uses it before you commit.

I have met folks that bought boats with diesel stoves already installed and wound up replacing them with alcohol or induction electric stoves.

I would love to be all diesel. I can manage space and water heating with diesel but I won't have a diesel stove in my living space and I can't afford a decent diesel generator.

cool...those VT plates bring back memories. Spent the late 80's & most of the 90's in that great state.

Growing up in Sandy Hook, Ct. we used to get off the bus at school get into my buddies car and drive to Vt. and then turn around and head back, stopping at cool places along the way and getting high. Did a lot of skiing in Vt. Plates remind me of my old Colo. plates.

The other day I went to start it and the batteries were low and not spinning it fast enough. I hooked the battery charger up for a couple days and just went to start it up. The batteries show 100%, but when I turn the key, I get ZIP, nada, nothing, no lights or anything.
What should I check first since nothing has changed since it turned over the other day.
While out there I remembered I got a call from the fuel card people to complete my app about 3 weeks ago. I came in and called and the girl told me she had just sent me an email this morning to follow up. I checked and see that she sent it at the exact minute I was calling them, weird.

[Mountain Gnome]

well, short of you not reconnecting the batteries, I'd check the key switch first.
