This is the best information about the Complex instant shower that I have. Thank you for reminding me that I am the master of my own destiny!

As some one who survived acute severe carbon monoxide poisoning I can tell you no, you just feel the most incredible tiredness you can imagine, you desperately need to sleep, luckily training said some thing odd go to fresh air now, and that where I was found 2h later, collapsed at the door face looking out, where just by good fortune it was winter and cold air saved my life, This was a logging camp shower house, in a home you may just go to bed and whelp that's it. Only way to know is to have a quality functioning CO detector! (In case any one was wondering how it happened: Some self described genius used a natural gas water heater on Propane (they made a co generator) Natural gas uses a larger orifice then propane so it was insanely over fuelled)

Oh wow, thanks for this video. I'm just about to start taking the casing off mine and see if I can work out why it's not igniting anymore. I've had it a week. It had been going great but one or two occasions it didn't fire. Yesterday.... Nothing. I troubleshot the inlet, outlet, batteries and gas... All fine. Looking forward to your stress test video now, but my glamping guest can't wait weeks for a shower 😬 I'm going to have to get onto the company!

Been using these for a couple of years, only problem I have had was leaving it in the rain with no weather cover 50mm hour rain for 4 hours kills just about anything . Just changed it with a spare unit I had problems solved . Cheap and reliable

Thanks mate, my water heater just all of a sudden wouldn't light, you can hear the igniter sparking it just won't light, I'm in the process of trying to find out why the gas won't come through, but when I find out I'll you and others know what the problem was. Thanks for the vid it was very informative. Seeya Rob.

I had one of these things on a food truck. The relay decided not to work so no propane coming thru. I raised the voltage to 4.5 (an extra battery) then eventually got rid of the batteries altogether buying a dc to dc converter to go from my 12v bank to 4.5v supplying power for this thing. Other than that it was great.

Thanks cool vibs and hot water!

This reminds me of those cylindrical hot water geysers people used to have sat over their sinks with that long tap sticking out the side, and also in bathrooms of many decades ago where people used them in a very much sealed room and ended up permenantly "falling asleep" in the bath due to CO poisoning, thank goodness for the balanced flue we have today... :S

I was looking at these for my camper van

I have one like this and a forced air unit they are made by Marey . the draft one needs 4' of stack to draft correctly. I would not use in a truck or trailer. mine is in a shed to go with a washer and drier , works good. i have not changed the batteries in a year. i have the forced air unit in a travel trailer and love it

Hey David thank you for posting this video, I am using it to fix my Westpoint thingy. One remark though, the pressure sensor should rather be referred as a pressure actuator which opens the gas inlet as well as moves the lever on the micro switch to start the igniter (the small electronic box). The sensor on the outlet is for the display of the temperature not for the pressure. The other sensor near the heat exchanger is to prevent over temperature, what I have read from the Internet is that this one which sends a temperature signal to the micro controller to cut the gas supply by closing the gas solenoid, if it exceeds 65 degrees centigrade. It seems the first design of these things was from Rinnai, correct me if I am wrong.

HI DAVID from Arizona, USA , missed seeing you Bro. !

Wicked content 👌

Thank you

I got a 47kg lpg bottle for £80. My camplux water heater comes today from amazon. I opted for the 16 litre version

Hi David, thanks for making this great video. Very helpful to understand how the thing actually works. I'm having a trouble with mine. Temp does not get higher than 30ºC even with max gas min water flow. Gas supply is fine. Just put in a new regulator. Any idea what it could be? I'm off grid and using mine with a 12v 4A pump that runs on a car battery. Curious to hear what you think. Thanks

the 25k info on the label means it can heat the water 25 degrees ( on the one i've played with said it was measured in Celsius) above the input temp of the water on minimum gas setting and minimum water flow. different unit/model to the one you have the one i've seen can go as low as 5L per minute

heck yea subscribed

What you called a thermocouple is probably a flame rectification electrode, it sends a very low AC voltage to the electrode and through the flame. the flame rectifies that to DC and returns it via the burner that the control box will see and confirms its alight, if no flame nothing can pass to the burner and it would go to lockout. Much quicker and more reliable than a thermocouple and cannot be bypassed.

Are there water heaters similar to this that could be used in campervans. Thanks 😊

I have a similar heater in my static caravan, Cointra CPA 11 Litre LPG….it’s great (obviously it has a flue fitted)

Hello!! From Arizona USA. I have the same model Camplux heater as this one. I’m reassembling it after repairing the copper pipe which busted after a severe freeze. Regarding the reattachment of the cover wires to the unit wires. Which go where?? On the cover we have one set which is a blue & black combo and another one yellow and black. On the unit there is one blue and blue and another one which is blue, yellow and black. What attaches to where. Any help would be appreciated. 7:55

Do u no haw to disconnect the 20minit shut off

Are you sure you do not have the BD264? I thought the BW264 has a third control on the front for Eco mode...

Im planning on building an "apartment" inside a 19/26 ton boxtruck, with 2000L of water (and grayewater) and everything you'd find inside the modern apartment. I've been thinking of using something like this for my hot water needs. You've given me all the info I need. Gonna put it in a box with a sprinkler inside, just incase

I have a similar unit made by joolca I have mine in a vw transporter mounted on a TV bracket so it can be outside vehicle quickly

Mine is vented to the outside to the outside. I only use it for showering inside my camper. Co2 monitor raises to 10-12ppm after about 1 min of use. I then open the side windows to add extra ventilation. Touch wood, I haven’t been killed yet.

I was looking at 12 volt RV direction ignition furnace parts/systems. I want to make a direct ignition automatic thermostatic radiant propane heater that is portable running off a small lpg tank and small battery. It looks like the cheapest way to get a 12 volt control/ignition system is to buy one of these and take the parts from and it and mash it up with a buddy heater type head.

What is the bag of hardware for?

love this, thakyou soooooo much!!!! so helpfull for my troubleshooting! Incidently...... I actually have one in my camper - for a year or 2 - been working fine - properly flued and all that (removed the fan from the flue as i didnt want to build a rocket engine!) - got a M02 alarm right next to it for safety which has worked in the past - now the water heater is not working (so after fiking about with water input etc and pressure (as I thought this might be the issue) - still cant get it to initiate its sparking mechanism... still investigating.... very helpful! will investigate ignition system with my multimeter...... any thoughts? yes the battery are a big joke, snapped off the same battery clips! but hey - it cost me around 110 quid when i got it - my version is a little different - has a winter/summer knob.... they all pretty much the same from what ive seen..... thanks again buddy!

I think I make a concealed thin steel box with a (outside) air in and double insulated outlet a bit like combi boilers work. Guess it’s like you say as well, your not using it while sleeping. I see a lot of people yelling about the dangers and carbon monoxide and what not while at the same time they are using a gas hob and oven.

David, i have a BOSCH thats constructed in the same cheap manner.

I have the same unit and was really pleased with my Camplux water heater until it started rusting…the exterior paint/ powder coating bubbles and then cracks and peels after a few weeks of usage. The shower head becomes yellow after time too.Pretty gutted really it’s not even 2 yrs old

when they sent it for review , i wonder if they knew the first thing DM would do is take it apart to see how it choches ??

How about using this to heat the water in an inflatable hottub? The 2kw heater in the lazyspa is expensive to run and very slow to bring to temperature. Thoughts?

Hi! Thanks for this video. I very stupidly installed one with an on/off switch on the shower head. I turned it all on but they shower head was ‘off’ so the water pressure (being tankless) just exploded the unit and water came out everywhere. I since bought a replacement and learned my lesson. My question is, with the old one is there a specific part I could replace or adjust to fix the damage caused so that it works again? The one I have is identical to the one you have. Any advice would be amazing 😁

Assuming I ever get it back, we could see how much of this camper van stuff we could jam on the Landcruiser. Then overland up the campsies and shit in a bucket.

Great video David! Quick question, how loud is it when it's running? Thanks!

8:15 I mean, there's ONE way to make sure it's off with a switch... A waterproof missile toggle switch! :P

thought mrs doubtfire was the voice after the helloooo

i think i would swap the d cells out nad have a 18650 and holder

Will it work on propane or butane?

I'm guessing you will need a reasonably good pump to ensure it works correctly. I wonder if one of those cheap whale ones would do the job? I've got one supplying my sink in the van and it's bloody impressive for a wee £11 submersible pump...would be an interesting test though!! Regards Mick

Hi there, I have a 8L per minute portable hot shower unit similar to this, with a 8lpm 12 volt water pump and it's got hardly any flow out shower head.Its about a year old and worked fine. Could it be blocked inside or have air pocket somehow? Any help would be appreciated, thanks

Well that‘d be an interesting project: Make your own biogas and connect it to a solar-generated power sources complete independence!

I got a similar of ebay and i found it was not hot enough for what i wanted so i added copper cpu heat sinks to the inside of it to capture more heat before going to the heat exchanger and added some more insulation works great now, use as and emergency heating for my solar hot water.

Torture test, I like your humour 😂

I ended up having to remove the plunger off the solenoid for the propain because its the cheapest POS solenoid they could find from China. I know it's dangerous, but i only use it outside. Also, i used a usb cable and a cellphone charger to power it.

My Chinese gas water heater has a switch on the bottom where just where you want one.

Not an on off valve, a butterfly valve ... it flutters. not pressure sensor, uses a flow sensor.

Have anyone hacked this thing so it doesn't turn off after 20min?

Nice video , But 90% seems optimistic.

Water pressure pump

I threw a 12v buck converter on my unit and ripped that dumb D battery holder out of there.

So a gas stove in a rv is ok but a hot water heater is danderous , id like to see a carbon monoxide test please,,,,,,,show how much comes off a stove with an oven and this heater , i bet you get 0 on both ,,,, the main issue is it eats oxygen,,,, if you have a window cracked this is fine indoors , also you could vent it as well , but hey go shower outside ,i prefer the privacy of my camper ....

"Hello" is very annoying, sorry.
