Very impressive that they can heat the water that fast while flowing water without a heated reservoir.

That Chinese heater is amazing. Even has the water pump built in. Seems really powerful too. Shipping cost seems really high though. Someone needs to import a container of these and sell them locally. Thank you for testing this.

The little knob thing on the valvestem on the spray head can usually be used to used to increase or decrease the flow for hotter or cooler water with the always-on clippy thing in place, used a similar setup in my first house which only had a bath and no shower, was cheap and effective... :D

Wow that quickly. I think it will work. I would plumb it like a house is plumbed. Let the machine heat the water tank in a plumped loop. Have a cold water inlet to keep the hotwater tank full. Have a water faucet with the hotwater hooked to it and a cold water hooked too; to control the water temperature for a comfortable shower. I found a 24kw 12 volt heater. That should keep up with the hotwater demand. Thank you for taking the time to set all of this up and giving this demonstration. You rock.

Great stuff.. Cheers

Hot tubs have a flow control valve. That will shut off system with no flow. Also need to use a thermostatic mixing valve.it will prevent scalding. Check out the rixen hydronic system.

That is quite close to a saleable product! An arduino away perhaps from an off grid HSE decontamination shower or caravan combi boiler. Your average domestic shower head delivers a lot less volume than your garden sprayer head. Excellent mock up.

Put smaller diameter riser pipe to your shower head then it slightly lessens the flow rate through the whole system which allows the water to gather more heat on its way through and slowing the volume used.

do these have a thermostat control option based on coolant/water temp?

been considering one of these , what happens if you forget to turn on the water and start the unit up? does it have any protection?

Just thinking about the flow/over pressure issue. Maybe flow switch and pipe temp sensor on the outlet, pressure switch on a tanked system as safety switch, rundown timer on burner with bypass valve to run cold water through it during cool down . I.E. shower flow stops, flow switch sends signal to open bypass valve and actuate rundown timer. Just ideas for safety systems. Good testing though.

I liked the JP Chinese "Trauma" lol, but I think this is the best option.

Just need a bypass so that cold water from the tank can be drawn at the same time to be mixed with the hot at the shower riser pipe to control temperature but put a smaller bore hot riser pipe on it so that the flow is restricted enough to give the maximum comfortable heat when the cold water bypass is not adjusted to mix in.

Closed circuit water in and out and add a new pump to extract the water from the tank!

I’m working on a similar project using a similar set up for an off grid washing machine but running into some hurdles with water pressure at the right time for the fill sequence of the washing machine.. let’s just say its a tough one but the challenge is the fun part

Have sufficient storage for big use days. Best of luck it’s what I did in southern Spain/conil.

Probably already been said but a thermostatic mixer valve in combination with this would deliver at constant temp.

Simple solution is put an inline 90 degree tap on the pipe, fast easy control, I regards to saving water till it’s warm, have a t on the hot water pipe to return water to the tank, once it’s getting warm shut off return to tank with a tap, and open up tap to showet head

What if you wanted to heat the air in an RV, but you are not using the hot water?, will it cause an issue of overheating the unused water?

Thanks for the videos, appreciate them. I still haven't figured it out which sisten to install in my camper for both hot air and water. I've seen that new chinese heater for both but since you can't heat the water without heating the air, it's not a reasonable solution. (maybe redirecting the hot air towards outside i the summer). Was thinking of using two separate heaters, so one like this for water and one normal air heater and I'm wandering if I could use the same diesel intake pipe line from the fuel tank for both with a Y splitter... do you thig that will work?

If/when I ever get around to another van build I'll be using two seperate diesel heaters. One for the water and the other for the air. The combined heater just didn't give enough hot water, 500W compared to the 5000W of the Webasto. Now the clones of the diesel water heaters are becoming more available it should be even cheaper to implement. A Y splitter will work for the fuel line as the fuel pumps themselves act as one way valves. Perhaps run a larger diameter up to the Y.

I will plump into the cold water line of the propane hot water tank with a flow control switch to turn on the diesel heater. That way the propane will give you a small amount of instant hot water but the diesel heater will give you longer hot water. If the water is hot going into the water tank than the propane burner won't turn on. I was thinking of doing that with a propane instant heater but diesel would be cheaper and easier

That is awesome. Very cool.

Great channel mate, I'm very curious to see how efficient you could make a Chinese diesel air heater by putting an air to air heat exchanger (recuperator) on the exhaust and combustion air intake, see if you can get most of the waste heat out of the exhaust and back into the primary air. I guess it would be easier and more efficient to get the heat from the exhaust into the heater air intake (as opposed to the combustion air) but I'd be afraid if there was a leak in the recuperator that the exhaust gas would make it into the hot air delivery and suffocate someone. It seems like an obvious efficiency upgrage, basically turn it into a small condensing heater. I'd be very interested in an experiment like that. Thank's for all the great content.

@unmountablebootvolume

3 жыл бұрын

That's the concept the german Veritherm boilers use. They are basically normal condensing boilers with a combustion air heat exchanger added on, which made them incredibly efficient, even when runnig at very high temperatures. Sadly some "fakenews" caused a huge shitstorm against this boiler in the late 80s/early 90s, which made them unpopular to this day. Luckly the manufacturer didn't care, and even gave their entire boiler lineup digital controls in 2004. You can actually still buy one new, though you will have to contact them directly. I think it's a grea idea to try this concept on one of these heaters, though i'd worry about the plastic of the impeller melting/getting brittal.

@josephinring

If the plastic of the housing and the vents can take the heat I’d imagine the impeller would be ok, I can’t imagine the economiser would heat up the incoming air to an extent that it would melt the plastic. If a manufacture decided to do it for a production model they could simply put the impeller before the economiser. It would be a very interesting experiment. Probably need to run it exclusively on kerosene to keep soot build up to a minimum (as opposed to diesel).

Another excellent vidjeeo. Now, here's a question for you. I've got a (inoperative) Eberspacher D5W which once it is working will be plumbed to a 5L calorifier. With this Eber D5W (5kw, very like your webasto) a water pump, 5L calorifier (and some sort of anti-explosion header/expansion tank), will the Eber be man enough to give me a decent shower from the calorifier? Or will I need a 12, 13, 15, 16KW chinese jobby? At the moment, the calorifier is heated by 240v when on a campsite, and that gives me plenty of water for a shower - the calorifier is set to about 65 degrees and has a thermostatic mixer outlet valve, so I am using (I reckon)10L cold + 5L hot for a 40ish degree shower, and that is a long shower, very generous. Ultimate goal is to be able to fire up a shower without needing to be on 240v hook up.
