Hi guys thanks for watching this weeks vlog curtesy of the gorgeous Nesha. We have since done a lot more research and have made some changes (finally downloaded the BSS too). Thank you all for your comments. Dont know what i was thinking with the fresh air vent as like you guys have commented it should be taken from the cabin and recirculaed 🙄🙈 thanks for keeping us on our toes guys. And if you haven't subscribed you know what to do 👍🏼🖱️🔔
I take mine from fresh air taken outside the boat and passed boat safety get your self a bobil van kit too like I did it's amazing and you get hot water from your diesel heater great vid
@@nateuk2542 thanks for your comment ... Looking at the bss it doesnt say it needs to be outside just says a suitable tank fit for purpose should be used 🤷🏻♂️ not hard to pop a filler on tho ... Il keep my ear to the ground on that one 👍🏼
Hi guys just a bit of advice from someone who lived with a Chinese diesel heater in a caravan for a long time and learned from many mistakes. Firstly if you are running heater on a low heat please ensure that before shutting the heater down you run it on FULL chat for a couple of minutes to blow out the coke in combustion chamber which will otherwise foul glow plug and not fire up……. Symptoms being lots of thick diesel smelling smoke from exhaust and no heat.
This is one of the best installs I have seen of a CDH. Mainly because you are constantly questioning the safety of what you are about to do, and what you have already done, and making sure you are not making an error... or at least if you have then you are fixing as you go. Brilliant. I will check later videos to see how it went. PS I have been a YT viewer since it began, I think this is the first one I have ever bookmarked.
Hi guys. For piece of mind, buy a carbon monoxide alarm, then you will be belts and braces safe. Love your videos. Good luck with the rest of the renovation.
I have binge watched the whole restoration playlist, almost at the end but while I am on this video, I thought I would just let you know that you have a rouge video in your playlist No: 22. Action packed, crying over knifes, Split paint, how not to operate a jigsaw, but fully enjoyed every video. Keep up the great work both of you, but for now episode 23 is ending so its onto 24, nearly caught up.
Never had frozen water in my pipes in 16 years on my boat, have seen others have problems but they do not live on their boats full time as I do. I have made everything easy to get at just in case I need to get to electric cables and or water pipes on my boat, you never know when you may need access.
@@DriftwoodFolk When you live on a boat the water is always moving in the pips, washing and all that so less likely to freeze. If you go away and leave the boat for any duration of time that is a different kettle of fish, empty the water tanks.
Thanks for you comment much appreciated. Good idea ha we actually still havnt finished it as weve had to move on to other things (always do a job before you can do the actual job you need to do😅) next vlog is September 2nd as we are travelling alot with weddings and vacations but will put an update video on our list and try get one done soon 💪🏽 I know Danni & Joe have also fitted one too
Have a look at "Barnsley Boater" on youtube. He uploaded his installation video of how a diesel heater should be installed to pass the safety check. You must take the feed from your main tank and use the correct fuel line (throw away the fuel line that came with the heater as boat requirements are much stricter than vehicle installations where fumes or leakages cannot accumulate in the hull). My boat was surveyed last month. And the surveyor checked all fuel lines to make sure the correct specs were printed on the fuel lines. He even quoted that in the report. If your fuel lines to a heater have no printed specs it will fail.
Thank you so much for your comment. Ive checked him out ... Great install and really helpful so thank you for that 💪🏽👍🏼 yes we've changed all the fuel line to iso something ... They comply anyway haha
Hey Guys, the air intake for the air that’s to be heated sucks from inside the cabin area. No need to go to the outside world or you’ll be constantly heating cold air too 🙏🏻
Great video guys. You may of already fitted it but with the air intake I would leave it in the engine bay and maybe fit an air filter on it as the it’s the same as the engine. 👍👍
Absolutely don't put the fresh air intake and exhaust hole near each other or the intake in the engine bay. It's not any smell you need to worry about, it's odorless carbon monoxide in the exhaust getting drawn back in and sent to the cabin. (There can be undetected exhaust leaks from either the heater or main engine filling that chamber with CO.) Either use an external intake somewhere further away or draw it from the cabin space, though I'm not sure if the BSS disallows or frowns on that practice as they do seem to be adverse to cabins being sealed up spaces without fresh air.
Thanks for this ... The idea was to hood the exhaust and to hood the fresh air vent away from eachother so this wouldnt be an issue.... But on reflection and a whole lot of researching gonna see if we can take it from the cabin as its only recirculating the same air just heating it on the way.
Well done the safety officer!!! your heated recirculated air needs to be taken from and go back into the inside of your living space, not from outside.
Another observation. Will your boat pass the safety check? I would say that it will fail. Because I also have a separate tank identical to yours for my diesel heater, and the marina refused to fill it. Simply because you are not allowed to store any separate fuel containers "even empty ones" anywhere in the boat including the engine room. So I have a problem because I need to install my heater in the bow area & the maximum advised fuel line is 2m. And I also have a 45' boat. So you need to check the regulations before you pay for the safety check as I think it will fail. Then you would need to install a fuel line from your tank then pay again for that check. And its not cheap. Having the diesel fed from your main tank will allow you to use red diesel (unless they changed the rules again).
Thanks for your comment. Ive checked the BSS and all it says is that it needs to be a fit for purpose tank that is secure. (havnt actually secured it yet but I will😅) We actually wanted to have a separate tank so we didn't use it all for heating and could still move the boat. Very strange how your marina wouldn't fill the tank. As far as the BSS states it should be fine ... I know of a few that have done the same and has passed. We will be using red anyway so not to worry.
Hi Ya. So you are running a pipe the length of the Boat and having vents off of the pipe at certain intervals for heating sections of your Boat ?. The pipe is quite long so how powerful is this Diesel heater and the fan which will circulate the heated air ?. If say for argument sake you are going to have 4 vents off of the pipe I would imagine that the airflow/heat at the furthest point is going to be extremely low but at the closest point to the heater the airflow/heat will be high ? As the Airflow/heat moves away from the source it will Peter out which means that one end of the boat will be Hot and the other end of the boat will be cooler,so if it is fitted with a thermostat to control the heat and that is at the furthest point then the heater unit is going to be working hard all the time trying to supply heat ?. Would it therefore not be a good idea to fit some sort of circulating fan(s) to help the Airflow/heated air supply along the pipeline to the vents ?. I’m thinking along the lines if you have a water supply and a pipe and at intervals you put a tap for each room and each tap is turned on,the first tap will have a good pressure and flow but the second tap it won’t be as strong pressure and the third tap will be a trickle until you get to the end tap which has no flow ?. On plumbing I think you would have to install booster pumps to get a even flow,so on a hot air heater system you would need to fit some sort of booster fan(s) etc ???. The main thing with that Chinese Heater is not letting it work too hard,Webasco are more expensive but they are more resilient and better designed for the job that you are asking,the Chinese ones are good for small places like sheds etc but I’m not sure for what you are asking ?. What is its constant or long run time ok for ? If it’s going to be running 24/7 when it’s Cold weather will it be able to handle that ?. I think personally you should maybe speak with someone who knows better than me and knows the set up and what you are going to be asking of this heater….maybe someone at the Marina or the Boat Shop could give you some advice ?. I’ve worked with Webasco heaters but they were for HGV Cabs and it’s quite a small space compared to something the size of your Boat. Loving your videos and seeing your Home gradually coming together ❤
Hiya Leonard really greatful for your comment and thanks for watching. We are indeed yes. Its pretty powerful to be honest. Didnt want to get a lower one due to this thought too. My thoughts exactly ... My idea to combat this was to have slide vents that you can shut off in each room so the heat can continue to the next open vent. I know some friends who have a similar set up (and size boat) and they had the same worry and ended up not being that bad. Not sure where to put the thermostat as of yet tho but will ask and research and work it out. That is a great illustration and makes perfect sense ha thank you for that. (i learn by hands on stuff or illustrations so really appreciate it). Will probably take you up on that idea and fit a small fan half way just to keep the hot air flowing to the other end. Completely agree. Ive seen people take them both apart and apart from the quality of the castings they are pretty much identical. I know a guy who has a chinese diesel heater in his van and he does wild camping in the coldest of places and he pretty much runs it 24/7 with no issues. Mental i know haha. All we want it for is to take the chill off the morning and eveings so wouldnt be running all the time. Its just to keep the temp at a reasonable degree. Ive fitted one in my workshop (all be it a less powerful one) and ive run it 9hrs a day in the winter while i work and had no issues ... Yet....🙈😂. Yes weve asked around lots of people and looked at many many videos in the past 2 weeks or so. Realised many things that ive said and done are wrong and i hold my hands up to that. Theyve been sorted ha. Appreciated your time and all the info given. Oh wow okay ... Il be asking you many questions then 👀😂 haha thanks for watching and welcome aboard💪🏽
Looking at fitting one to my 34 ft sailboat. The challenge is different from a narrow boat if similar length in that the stern quarter of the boat is open cockpit and the forward third is taken up by v berth and head, so only need to heat something like a 16 foot (by 11 ft beam) space. Even so, I would still need more than vent but surely the problem you mention (of all the heat going to the first vent) is solved by having a controllable vent? That is, after all, how domestic (hot air or hot water) systems address that issue?
The fan in the unit will only move the air with a certain force. The corrugated ducting provides a resistance to flow and the longer the duct the greater the resistance. Think of it like putting your mouth over a pipe and blowing , you can only exert a given force if that pipe is one foot long the air will emerge from the other end without having lost much momentum. Now think of the same situation but with that pipe being 30 feet long or more the force coming out the other end will be minimal. The reason being that all the energy exerted by the fan will be used up in overcoming the resistance cased by the pipe . It’s made more complex when you introduce more outlets and introduce the expectation of heat being delivered to the far end. I would suggest that you have a good chat with someone who knows more about this .
You should consult a professional . Your return air should come from inside the heated space, locate the duct lower in the space where it will pull in cooler air and help create air circulation in the space. The supply air should be located strategiclly to the areas you are heating . Exhaust or flue gas should be vented outdoors where it is not located within an area with open windows or air intakes . Combustion air can be pulled from outside or inside but if you are taking it from inside you have to make sure that there is a make up air from the outside to make up for combustion air use. Like I said consult a professional.
Appreciate your insights. We have spoken to many people especially those who actually fit these but the instructions weren't as clear as they could have been ha. After lots of research and talking to people as well as comments we are all good. The understanding I got was it was a fresh air vent not a recirculation and that's where I was going wrong. All sorted now tho 💪🏽👍🏼
Thanks John much appreciated. Ive double and triple checked and the hose seems ok to handle it but on looking at it again im gonna cut it right back to almost nothing and put a marine fuel hose in rated for diesel just incase the information i have is wrong 😅
@@johnglover9935 yer ive finally downloaded the actually BSS (took long enough to find it) and will be checking it with our work and adjusting if needed. Yes i believe its ISO 7840
Sorry to say no to the fuel pipe , has to be of none combustible material, join’s can be of rubber but marked with iso numbers and joined with fuel clips, if using copper 6mm flare the end before rubber pipe connecting pipes. Air intake: take from inside cabin as that is clean air and warm and more efficient. You don’t want air from other boats exhaust or your engine compartment. Any other advice please ask
Hi Keith appreciate your comment. Thanks for all the info 👍🏼 ive checked the hose and its marked with an iso number so all good. Since the video the hose has been sorted and clipped properly.
Appreciate your comment ... Only reason to take the fresh air in is not for the combustion air but for the heated air (which you will be breathing) so cant be taken from the engine compartment under any circumstances
I wondered why you are not having the type of diesel heating with radiators like the boats usually do? I have not seen those types of diesel heaters on boats but in vans. Wishing you well with the install but please seek boaters advice for safety. ❤
Hi Ann thank you for your comment much appreciated. Our reasoning for the air heater instead of a water heater (for rads) is basically because we have limited wall space for radiators as its a small boat but equally needed heat so this was the option we came up with. We will of course have a stove too but this will be mainly used to take the edge off those chilly mornings and to stop the temperature dropping to extremes.
Are you not meant to draw in air from your cabin so it gets circulated and reheated costs less to heat your boat. It is to close to exhaust fumes. You'll give yourself carbon monoxide poisoning. The fresh air vent is probably the intake for exhaust that goes there.
You are going to have problems. Diesel heater exhausts should run downwards as they condensate in cold weather and fill with water. This causes fumes to backpedal through the heater. The exhaust needs to be on a constant downhill run. I have fitted 20+ heaters and also put many bad installations right for people and have seen this problem many times.
Thanks for your comment ... We will be fitting a drain onto it for that reason as there is just no way to make the exhaust run down hill unless its under the waterline 👀🙈
@@DriftwoodFolk Plenty of off the wall heating expansion idea if your into it. Maybe box the lot in a semi air tight boxing, under the outside decking but leaving the air intake for combustion out of it and with a 12 v computer type fan on the far end blow the units heat back through into the cabin, but of course keeping in mind the noise and exhaust fumes from your engine and the unit.
AVOID ANYTHING CHINESE that needs to last or where a failure would have significant consequences. The low cost of Chinese “anythings” is reflected in the quality.
Thanks for your comments guys .... We went Chinese diesel heater as after much research I found that they are pretty much identical to the expensive ones. The casting is abit less refined but still fit for purpose. After swapping out all the rubbish fuel lines and filters it's essentially the same as the more expensive versions at half the cost. Plus if we get a few years out of it and it goes we can but another and it will still be cheaper than getting one expensive one 😂. There's a guy on RU-vid ive seen and he had one in his van and took it to alaska in the snow for a long period and had no issues. He later took it apart and laid it next to a webasto and compared and they were identical. I'm normally wary of such things but I have one in my workshop and has been working fine for years 💪🏽
