I work heavily with all sorts of valves and seals, I recommend to remove the o-ring and lubricate underneath the o-ring as well, this ensure maximum seal by allowing the rubber to freely take the needed shape to facilitate the best over all seal on the mating surface
Love your videos! I have a "Happybuy" Chinese heater in my motorhome that has been chuckin along for 3 years now...watching your videos makes me feel like I must have really gotten lucky with my purchase! Keep up these videos and your humor...very informative and entertaining.
Hellooooo back from the high desert of New Mexico USA 🇺🇸. I can't wait to see what you do with this heater. Keep up the good work and stay safe and God bless you and your family
Thanks again . As a admin of a couple CDHeater groups I often send people to your channel because Your vids are informative and not a one hour long rambling nonsense.
That is a very tempting proposition. I think that I can see one of those in my boats life in due course. A bit of heat sink in the water circuits return to prevent boiling and bingo heating and hot water. Lovely jubbly! The current hot air is marvellous but hot running water is a game changer.
Another cracking video,. Very informative like your previous ones. Being a tight Yorkshire man , I have now invested in one of these to heat my house. One criticism of this video is that you didn't say c**t at anytime (unlike some of your other videos). But. The odd f**k was most welcome x And I have now subscribed since I love hearing MidgeUre say f**k and c**t
Hey David, would love to see more details with the controller. Does it have the ability to setup startup timers? Also can you operate the air and water heater independently of each other, I.e. run the pump without the fan to heat the water faster. Thanks!
David, id like to see how this would perform plumbed into an indirect hot water system ie a hot water cylinder. An easy way woukd be to utilise a car header tank and a basic PRV. Great video though!!
Thanks David. Its good to know what is available. Price is a bit steep. I think I will stick with my original plan to electrically heat the water as I use it - an inline electric heater in the van. No storage or the losses associated with storing hot water. I have huge battery reserve, so not concerned about power requirements, and I already have the diesel heater.
Heating water with electricity is a really bad option especially considering the giant heat pump in your van called the engine. I made a heat exchanger inside my water tank to warm the tank with engine coolant. it works really good. 35 gallons hot in 15 mins.
@@thomasbarlow4223 Thanks Thomas, I agree, better to use waste energy from the ICE than generate heat for water, but I have a 4x4 and a camper trailer and the hot water is needed in the camper, so the waste heat from ICE approach is a little impractical. With 13.5kWh or storage and 1.5kW of PV, I can't see any downsides.
As others have mentioned, I've been enjoying bingeing your videos. Thanks for testing all this stuff! On the site, it mentions you can run this air only (without the water) can you run it water only, too? I'd prefer this over the bobil vans product I think. Otherwise my plan is to use a diesel water heater alone with a heater core and fan for heating air.
can you use air heater only with out water pump going? just thing of one for in camper to have a hot water tank and when water gets to temp shutting water pump off and just having hot air blower going. but think the water left in heat exchanger may boil and create pressure in pipes and hot water tank system
at 17:50 you mention your average temperature readings being off. Have you tried setting a temperature square on the FLIR and using the average reading from that?
Interesting!! What happens if the water boils in the chamber? I'm thinking of one in my camper, but sometimes the heater is run non-stop for a few days so I'd have to turn the water pump off once my 10L tank is nice and hot
So you could use a radiator with a vented hole put water in it and the pump would recirculate the water and then just top it up when needed! Or use a vented tank tank with a tap to turn off and on to wash your hands in the garage or shed ect and just keep topping that up when required . ?
I have, it works fine however be mindful of cable length as the voltage is read at the LCD control. To long/thin guage resulted in false low volt cut out.
Are these being sold in the UK now? Would it be possible to rig up to a radiator or 2? I love the Chinese hot air heaters but they are only 4kw max. I would love a 6 or 8kw version.
Curious if you've reviewed the diesel water heaters that don't additionally do air? I've been looking at a couple online specifically made for hot water. Now my biggest concern is if you use one of these diesel water heaters in a pressurized system (say, 30-40 PSI) will they crack? Are they safe for showering and dish washing? I've had a heat exchanger from bobil that unfortunately cracked due to the PSI being too high, and it wasn't even heating when it cracked..
Did this model have GSM? I’m thinking of getting one so I can text it in the morning to preheat engine coolant as have online heat exchangers to warm fuel lines for veg oil conversion I run on (just my engine not the heater) Only thing is the website is unclear if I can use the GSM to active the water heater part as well as air heater part 🤷🏼♂️ messaged them but response I clear or my question lost in translation. Great videos, keep up the good work!
Hi David. An other good review of these air&water heaters. Thank you for that. A have a question. Maybe you figured out how the controller works? Does it work as a thermostat keeping the preset temperature? If yes, based on what - air temp, water temp, device temp? My use case: I'd like to put it into my overlanding vehicle and attach it to the engine cooling system. Then use it to preheat the engine in a cold morning. As a bonus it would preheat the interior as well. But I would like either thermal cut off based on temperature of coolant (water) or at least a timer. Can you please share your experience with this type of the controller you have. Is it possible to get different controller for this type of unit or build one based on Arduino? Any info very welcomed. Thanks a lot.
You do know that if they shipped a unit with some wrong parts,, that unit wasn't supposed to go to you?? I was meant for me, I'm a Sh-t Magnet for bad shipments - Ha! Well done as usual & helps me to sort these CCD out in my head, well done
Will a 20ah x 12volt golf walking buggy battery on a battery charger full time start the diesel heater up when It is pull 10 / 12 amps for 10 minute start up . Thank for excellent Videos and helpful comments
So while yes you will get additional heating from the radiator, it would still be part of the total possible energy from the fuel. It would just further show any flaws/rounding in my readings from the other parts of the system.
This might be a stupid question but I'm looking for one of these heaters to heat my exterior tub. It is a 3000l (~790gallons) water tub which is currently heated with a Snorkel (Scuba) stove. If the water has around 10 degrees Celsius (50F) it takes around 5 - 6 hours to heat up to 39 degress C (102F). I'm looking for a solution to get the water heated maybe a day before since I have access to waste motor oil. What's your tought on this :) ? Thank you!
None of these heaters do well with even diluted waste engine oil. The additives in oil cause carbon, ash and slag build up in the atomizing mesh as opposed to true oil burners that use high pressure pumps and a nozzle to atomize the oil. They do sell water only variants of this heater that would work much better for just heating water.
I'll be amazed the day they release a heater which actually is the stated ratings, rather than the inflated figures they tend to be, but I doubt that'll ever happen, I'd have better chances playing the lottery... :P
so im wondering what would be the purpose of the water heater? it would take a long time to heat enough water to use for say a shower would it not? or is it intended for like rvs just for use in like a sink or to wash hands? just kinda curious thanks!
I think they are for markets where temperatures get really low. Russia for example, would be normal for -35 degrees. Cars and trucks have a tough time getting started on days like that.
David McLuckie Thanks for your great videos and information. Do you know or think this or any of these diesel heaters could be used to pump cold water hot tub and send it back hotter? thanks
The combined air and water aren't powerful enough. But there are plenty of diesel fired water heaters to pick from now. Like this - s.click.aliexpress.com/e/_DFN9aBj
@@DavidMcLuckie Thanks for that. So with the one you sent am I right in thinking all I would need to get this to heat hot tub water is a fuel tank? thanks again
@davidmcluckie your videos are great!! I live in Ayrshire and wondered if I could convert my tub to using one of the water only heaters. Could you do a video and do you think running costs justify purchase?
Hellloooo.. I’m currently installing one of these models in my van today, thanks for the heads up with your videos… Do you think I can use the afterburner controller with this unit? With a compatible ecu of course from my existing standard 5kw heater… Will afterburner fuel settings be the same for the so called “7kw” and 5kw burners? I already have a pump recirculating water/water temperature sensor in my tank so I would have the water heating separate from the air heating. I’m using home assistant so I can automate using body temp/water temp sensor and water pump switch
I see you've already answered your own question on the AB Facebook. I lurk there too. :) As Ray has said regarding the error. Make sure the magnets in the fan are passing the sensor. I've seen ECUs with a long and short sensors and they don't always line up with the magnets.
@@DavidMcLuckie Top man 👍👍 made some adjustments and she’s working. She started smoking from the body inside the van like, I might not have the correct mixture settings, setup for 5kw 🤷♂️.. or maybe because the body temp sensor was not correctly installed and AB was trying to compensate.. Thanks for your comment it got me running. 👍 and thanks for lurking 👀
hi pal i have a water pump on an old truma system that ran on gas,ive removed the truma water heater and air heater and currently using the pump for the cold water feed as its fitted to my underslung tanks, ive blocked off the hot water pipes..is it possible for me to re connect the hot water feed to one of these.? my pump is above the water tanks..kind regards..its my understanding the water pump has nothing to do do with the fuel pump so there shouldnt be any issues on that side..my only query is when you said the pump supplied with the heater should be below the water level of my tanks as mine is above..
The supplied pump had no self priming, so had to be lower than the tank to fill the pump with water. Now while this heater will provide hot air and water, unlike the Truma it's both or nothing. You can't just have hot water, or hot air.
Hi David, I run a 5 KWH diesel heater in my greenhouse and run the exhaust in to a 2'' copper pipe that is 10' long then out through the back of the greenhouse, the pipe gets way too hot to put your hand on right down to where it exits the greenhouse. Is it likely they claim 5 KWH output including the heat lost through the exhaust which may or may not be recovered depending on the individual set up ?.
@davidmclukie Can the water heating run independently to the air heating? Considering one of these in a camper build. Does the fan just not run for water heating only?
David,ive just bought a very similar chinese version to go on my narrowboat as i have the radiators and pipes already in splace,is it a good idea to fit a small expansion tank in line
@@DavidMcLuckie we fitted the heater in but couldnt get it to fire,had 11.9v to the heater wiring and 5 amp at the glowplug.,theres a pair of wires on a long lead that doesnt seem to be on the diagram,comes off the loom,what are they for
@@DavidMcLuckie Ive managed to get the heater all set up and working,only problem ive got is the pump supplied doesnt seem strong enough to push the water round the radiator pipes.four small rads ,length of boat about 50ft so 100 ft of plastic pipe,what size pump would you recomend,the little one trys but nothing getting warm.Cheers russ
Can you add to your tests. 1) how much back pressure it will operate at, until the heater backs off. 2) what is maximum input air temperature before unit backs off.
Oh my god. I was thinking about it also for the past month. A lot of heat is lost through the exhaust, what a waste 🤔. Run the exhaust through a radiator filled with water
Ooh that's a tricky one. I'd probably pick any of the actual brands. By that I mean I've had more luck with the branded versions than the unbranded. The Lavaner heaters have been great, but I've also had no problems from a Vevor heater as well.
Now if I could find one of these through a company willing to sell to US citizens that's be great. Every time I find one like this one,which is rare , I get either a dead webpage or a company that sells only within the EU. Not sure why these things are so hard to find but it is what it is I guess. That being said in your opinion which would be best , using one like this with the water jacket built in or using a heat exchanger from the exhaust side ? If I can't find one of these I may just get one of the bizillions I see on ebay or wherever and try to scavenging the heat building my own system etc etc BTW love your reviews and subbed.
This looks to be what I need. The only concern I have is if it can be used with out water to heat my cabin then connect the water side when the project gets to that point. Your take on this is appreciated but would not hold you responsible for your input. Do the instructions say anything about this. Thanks
Hi I bought the Trales alpene hydro hybrid 7kw diesel heater. After putting it together, I get an error message for the water pump. The heater works fine, but as soon as I press the water pump button the error message comes up and it all shuts down. I've tested the water pump separately and it works. Is there a know fault or am I doing something wrong, grateful for any ideas!?
Excellent question. You can, but not from this test. I'd need to run it again and heat the water and air at the same time and record the lower air temperature and use that number. The total amount of energy consumed in the system will still be the same.
I was wondering if you could sort of do exactly that for the purpose of driving a small dc generator so that the heater could be completely self powered 😅
I just wish the water pipes came out the side. I've been waiting for a decent one of these to come out that is air and water and I think I'm gonna grab this one. It's just the way you mount it your water pipes end up outside unless you get clever which I'll have to do cause it freezes around here.
David McLuckie -good job! like always. But one "hard" question: How the system is secure in the case when the pump is not receiving hot water?? Becouse.. in ex. my shower boiler (150liters) has 60C?...If I stop the pump then i have a problem with boiling water in heater?:(... Solution: I can make "drainback system" but then when I will later start cold water on very hot heater...i have temp.shock and crack the heat exchanger?? (English is not my native language-sorry:) )
Hey , men- ladies checked your air filter on those diesel units you may be in for big surprise inside the round diesel filter was Nothing 0- just plastic cylinder and slits and 1/8" holes on top No filter media in mine So it will real fast peice lawn mower air filter does the trick
Have you ever considered testing the fuel used by the diesel engine in a big truck as opposed to using a heater to keep the truck warm inside at night?
What John Mac said. My Googling says a truck at idle uses 0.75 - 0.8 gallons per hour. A diesel heater at full power would consume 0.1 gallon per hour or 0.04 gallon per hour on low.
Hey I have a small Shop Where I grow fish and I need Constant Heat sov i was looking into diesel heater kombination system but I could not find any people that has done a long term test so my question is Can you do a test for the weak where it is running on it lowest settings an What long terms problem Could Be by doing that
@@MichaelGreenhalgh That said, what about running on a lower calorific fuel with a lower ignition point? Thinking here 28s kerosene (plus a small amount of lubrication?).
@@DavidMcLuckie seems like the website has a problem. it is mostly down or buggy. yesterday i was able to get the heater into the basket but the website failed to let me acces the payment options. Support seems down also. I got 1 reply a week ago. I asked about the measurements of the diesel heater metal box. After i resend the mail 2 times the support gave me some fairly detailed measurements. I asked for more precise measurements and after 1 week i havent got an answer yet.
@DavidMcLuckie have an idea for You... quite "unique". How about a cooking episode? Not Julia Childs sort of affair...... an episode that utilizes the abundant heat a Diesel heater emits - in most cases unharnessed - exhaust pipe heat. Kabobs, or sausages cooking while You toil.... that's motivation ;).
