You had me at capacitors.. 😊
:) Lol, you would have loved the video I actually shot about that. I rambled about electronics and circuit design for half an hour while I fixed it. I edited the video and then realized it wasn't exactly for our audience. You have used the little aquahot in some vans, right? I do love the idea of doing heated floors with it.
@@MortonsontheMove Would have? Some of your watchers would actually be interested in that video. I may be a little on different side for your viewers, but I would love to see the video on your replacements of that unit with a digital one.
Sounds like a great Arduino project. Two, actually. First a monitor to reverse engineer the timings on the pins and then the second is the digital controller.
It has been a couple of years since I watched the channel. Glad to see you two are in the coach. Ours has an LP model and I love not having to change the igniter. One issue I had when we first bought the coach used was a stuck check valve that prohibited circulation. Fortunately, I found some information regarding a fix online and got it to work. We make sure to turn it on every couple of months to circulate the boiler fluid through the floor heating system. We are in a 2013 and have not had the issues you are having. One pump our, one check valve stuck, and ignition issues with low fuel pressures sums up our issues. We are five years in our coach.
Great illustration!! Definitely a complicated system
Great video. One other "hate" at least with my 250d is that they dont work well at high elevation. It affects the boiling point of the fluid and causes frequent boil overs. The "fix" from Aqua Hot was a bigger reservoir. Basically it just overflows a little less now, lol.
I am impressed and have some of the same impressions. I have rebuilt my tank once (weld split), changed the system to non-pressurized, and added a spin on hot water filter that filters boiler fluid. Mine now has over 12k hours.
Nothing better when it's working I agree!
You’re lucky that your Aqua Hot is out near the outside edge of the motorhome. My 2000 Monaco dynasty has it in the center of that compartment. But I still love the Aqua Hot over any other system. I’m so glad my 100 series Aqua Hot do use of standard antifreeze and has much better built brass 12 V pumps. You should mention that the older systems at least 100 series use glycol instead of boiler fluid.
Dang! That would be tough, yes i forgot to mention that. It is a superior heat system for sure! Its crazy how cozy this thing is when its chilly + The hot water feels like in a home.
Our 23 Tiffin has a 450D and so far its been wonderful, with only a couple of glitches. The expenses this unit could some day cause is a bit scary to me, so I've tried to learn as much as I can about it. We are in Fl and SC most of the time, so it doesn't get too much of a workout. Probably only 150 hours or so per year. Running it once a month or so is great advice from one of your viewers. Thank you for an entertaining video.
Thank you, I appreciate how you walked us through the system. Your knowledge on so many topics is impressive indeed!
I have an Oasis. Low pressure fuel and runs on 12v. Very easy to maintain and mostly trouble free
Great video. I'd like to see a complete yearly maintenance video for my 450D to include fuel pressure etc.
Tom, always so educational. Not something I am wanting to tackle :) We will never get a motorhome with an Aqua hot. Heard horror stories about those things. Awesome video as always.
Lol thanks, like i said, its love hate. If it really goes I will prob a residential unit instead of replacing.
@@MortonsontheMove cant say I blame you.
Oil heat is alive and well. Been servicing and installing them for long time in my neighborhood. I’m looking for options to upgrade the heating system in the coach I’m buying. I have basement heat so I am thinking of doing a custom conversion with 2 diesel 28k btu heaters. I’d like the option to run one or both and send heat to just the basement or just the upstairs or both. I can only do upstairs or both currently. I’ll be digging in to see how it’s designed now and what will be best to modify it.
I’m a service and troubleshooter. That’s my specialty now a days. But I also design systems but more consulting now.
Lol. I’d like to rip out all that circuitry and computers and design my own system using relays and valves. I’m a mechanical engineer. This solid state and computer stuff is crazy. Units have thermistors all over the place and not serviceable boards unless you have an electronics shop.
I really enjoyed this video. You're very intelligent and definitely a geek. Love that. When you started talking about rebuilding the controller gizmo (technical term) I've done work like that so I was impressed but then talking about building your own with a PLC... how cool. I know what that is, so I definitely know you're a geek now. Very cool video and nice explanations.
When you have time, please consider making a video about how you made a Raspberry Pi Diesel Burner controller. I’m trying to follow your blog post and I’m struggling a little with the code and hardware.
That was such an informative video. Learned something totally new with that refractometer. ❤
Yay! New vid! This will be so helpful as we have the same unit!
I just bought a 1982 Eagle model 10 bus I plan to make into an RV and considering installing one of these into it if I can find a used one online or in a junkyard or something like that. I have a 2000 r-vision condor class A I've had for about 2 years now that has a standard RV furnace and water heater that I've had to service and this seems like an upgrade for sure despite the added complexity of the system
Great Video. I do my own maintenance on my 2006 Dynasty and don't know how you would own one of these and hire it out..... I did talk to an aqua hot Tech who told me run it though a cycle with Diesel at least once a month. Do not let it sit for months without running it if possible.
You have a very nice and robust rig.
Thanks, its a lot of work to keep it robust, but we like it. Our next video will show a pretty interesting mod fixing one big issue it has
Just discovered your channel. You could most definitely teach a course. I am sure this is crossed your mind, but you could do some kind of live classroom Skype or whatever people do to take classes online you could do specific projects or just an overview on your knowledge of different systems. Very interesting. Well done thanks.
I’m a plumber by trade. I’ve done a fair amount of heating, water heaters and electrical work. It basically looks like a sealed direct vent unit. I’m familiar with a lot of the different intricacies of that.
I gotta say, though you’ve got a nice area to work on it. It’s all in the front, thank God, you don’t have to get your head in there and lay on top of it and work from behind, Im all the technology you deal with
Lol, yes they did put it in a good area here, some coaches are not so great. Its a pretty basic system. What do you think of newer on demand boilers + domestic hot water units (residential). I wondered if the tank ever went out on this if i could retrofit it.
Thanks, glad you enjoy it. I have done some teaching in the past. Some of our courses are available through the RV life package now, but as of now were not doing any live classes.
Very helpful thanks .how much fuel dose it use a hr
Does the system work without ac power? Will it run on diesel and dc only?
What a complicated system. What is the cost of a new one?
10-12k! If the tank fails I prob will try to modify a residential on demand boiler unit to replace it
RV life, diesel maintenance, AND sidetracks on optical refraction and PCB rebuilding? I've found my people.
Lol, that sums us up! 🤣 Happy to have you here!
Dang, you are a mechanic , electrical engineer and coder?
I did not have the long hair/redneck look on my bingo card for this guy in 2024 - looks good though!
Are they using Aluminum Electrolytic Capacitors in timing circuits? No wonder they are having reliability problems!! They ought to have an oscillator circuit running into a long counter and do derivations off from that.. I would NOT put in the effort to maintain a system like that!! If you only use Aluminum Electrolytic Capacitors as power supply filters, you have a fighting chance for longjrvity, accurate timing, and reasonable repairability!! I would give that piece of equipment a big thumbs down!!
Right! No oscillator circuit; I did an entire video talking about the circuit and what I would do differently but realized it was not exactly for most of our audience. I even did a long segment speaking to my father-in-law, who worked with analog computation circuits in the 70's during the transition to digital, he's still a FORTRAN expert and we talked about how analog could and should make a comeback in some computation... I love nerding out, but Like I said, prob just going to go PLC, prob wouldn't trust my cuircit design anyway.
