For some while, my water heater had been working intermittently and then stopped altogether. I decided to investigate, disconnected it, and then removed it from its awkward position in the engine bay. With help from a fellow boater, it was dismantled, examined and the fault was found to be a worn-out burner and defective glow plug. This is not an instructional video, but I do give a step-by-step account of how we went about replacing the burner, refitting the heater and getting it operational.

Well done Alan. I must say, doesn't it give you a nice feeling of achievement when you do jobs like this, that you've never done before.

@MyNarrowboatVenture 6 месяцев назад

Thanks Graham, I agree I get a lot of satisfaction from doing this sort of job for myself.

Well done Alan ! You have now entered the Hallowed Halls of "Fixers"" It seemed straight-forward anyway ! Now all you have to do is walk up to a Radiator, touch it and say, ""Ooh OW ! that's hot"" Do you do call-outs now ? I clean my bolt threads with a small tooth-brush sized wire brush ! Head of the bolt in the jaws of the electric drill, spin it, and apply the necessary force with the wire btush and good old WD 40 / Brake cleaner. Bravo Alan, and Thank you Peter as well, for the Technical, {and human}, Support ! Stay warm ! Stu xx

@MyNarrowboatVenture 5 месяцев назад

Many thanks for your great comment Stuart. We shouldn't have separated the burner housing from the combustion chamber, as apparently there's no spares kit for the four screws and rubber seal. The screws were partly eaten away and very delicate, you certainly wouldn't want to be over enthusiastic in cleaning them. I'll do repairs overseas, if the client pays my travel and accommodation costs te he. Cheers, all the best.

@@MyNarrowboatVenture Ha ha ha ! Ill have to arrange that. We live by a large lake 7k x 3k 'ish it's only about 2 metres deep so a canal boat would fit in nicely ! It's used as a reservoir, but it's classed as a Marshland {Google - Kumphawapi Nong Han Lake and see}. Stu xx

Alan you keep on giving Absolutely brilliant vlog on tackling a tricky job Very well done to you for being brave and undaunted. This work will be saved in my archives for future reference not necessarily for the instructional content but for your tenacious " can do attitude"

Hi David, how very pleasing, I’m glad you enjoyed this episode. It’s really a straightforward dismantle and re-assemble job with a few niggly issues thrown in. I was glad we had a good outcome. All the best🤠

Im not a fan of DIY Alan, that’s only because I’m not very good at these things though. I did find this interesting and very enjoyable to watch. It’s great that you replaced parts,cleaned and refurbished your unit and not just bought a complete replacement. How fulfilling it must have been when you remembered the reset process to finally get it all working properly. Peter was very kind to offer his help and expertise. Well done both of you 👍 have a great weekend Alan

@MyNarrowboatVenture 6 месяцев назад

Hi Paul, thanks for watching and commenting, it is very satisfying to do a job like that and if I feel capable, I’ll tackle most things. Pete is always willing to help fellow boaters. You too have a great weekend, cheers 🤠

@IJ_uk 5 месяцев назад

Its very satisfying when you have worked on something like that. Rather rhan just knowing that the heater is hidden out of the way and the basics of how it works. You know in detail anout the individual components, its condition and how it all fits together.

@MyNarrowboatVenture 5 месяцев назад

I didn’t really understand how it worked until I dismantled it and put it back together, a fairly straightforward job in the end, but still a worrying one, as I separated the burner housing from the combustion chamber and shouldn’t have done !

@getubelogin 6 месяцев назад

I have also got a Webasto themo top C heating system on my boat, three pierces of information I collected over the years, one the unit should service the unit every 2 or 3 years, two you can diagnose problems on these heaters by connecting diagnostic equipment to them this is done usually at the start of any service and three they do not work very well with thermostats because if they run for less than 30 minutes the burner does not get hot enough to burn off all the carbon produced so it gradually builds up! Still well done for attacking a really difficlt job, it was very brave of you!

@MyNarrowboatVenture 6 месяцев назад

Hi Geoff. Thanks for watching, commenting and the advice. There is no thermostat on my system and I never turn it off within half an hour for the reason you state. I’ve had the boat for 6 years and never had a problem until now. I don’t have diagnostic software but now know someone who has. I just approached it as a dismantle and re-assemble and it’s pleasing and satisfying that all went well. Cheers

@michaelhiggins7365 6 месяцев назад

Well done Alan. I especially enjoy watching DYI repairs, please keep them coming. I suspect when you installed the water lines, there was air present in the system, and it took a few start attempts to purge the air.

@MyNarrowboatVenture 6 месяцев назад

Thanks Michael, that's right there was air in the system, which were expecting and got sorted quickly.

@groutmanalan5156 6 месяцев назад

Hi Alan just watched yourWebasto vlog and would like to say how well you explained the procedure. As an amateur like me it’s always a bit daunting before starting a job like that . A few years ago we had a Makuni heater which was always a pain until I stripped it down and re built it myself. Really glad it all went ok.well done. Ps we watched it from the comfort and warmth of our lounge at home 😅 see you soon Chris Silvester narrowboat Kagran round the corner in the marina 👍👍

@MyNarrowboatVenture 6 месяцев назад

Hi Chris and Nona, great to hear from you. It was actually relatively straightforward, dismantle and re-assemble with a new part. Apparently, we shouldn’t have separated the combustion chamber and burner housing, no spares available. The 4 bolts holding them together had been eaten away and were very delicate but they went back in without bother. See you next time you visit. All the best 🤠

Hi Alan, wow what an achievement and a pat on the back for Pete to come and lend a hand. A tricky job to do on your tod and reassurance from another boater is just the ticket!! Just out of interest what would have been the cost to have bought a whole new unit had you not had the confidence and petes support to have tried yourself?? A well deserved pint afterwards!!! A brilliant interesting vlog. Xx

@MyNarrowboatVenture 6 месяцев назад

Hi Lynette thanks for watching and commenting. I believe cost new is about £1500 but I have seen my type of of heater on offer for £1000. I've seen second hand ones offered between £500 and £800. Then of course there are reconditioned heaters and parts. I've used an original Webasto part in my repair. I'm glad you enjoyed this vlog, all the best, I hope you and Lester are keeping well.

@narrowboatlongpod4176 6 месяцев назад

I've repaired an Eberspächer but not a Webasto. My current boat has a Webasto, so will probably have to do it one day. The problem is that these diesel heaters are really designed to pre-heat lorry (and car) engines. They ideally run at full power for a short time and don't enter the low power cycling mode. Using them as domestic central heating boilers on a thermostat is not particularly good for them. We normally use the multi-fuel stove (coal is our fuel of choice) to heat the boat but do leave the Webasto on a frost stat when we leave the it. The Webasto is also useful for heating up the boat on cold spring mornings when the stove is not really required. It can also be used to heat water without running the engine (and not on shore power) but, again, this is not its ideal use.

@MyNarrowboatVenture 6 месяцев назад

Pete who helped me, has worked on Webasto air tops, they are different to the Thermo Top models. I'm not technically minded, so can't really comment on the comparison of the two. It was a straight dismantle and re-assemble. I use my Morso Squirrel stove, but the Webasto is good for cold mornings, as you say. Thanks for watching and commenting.

@dand5593 4 месяца назад

Glad that you managed to fix and also find some help. Quite expensive that part.... Regarding the power, those 5kw are managing to heat the boat? Be safe, healty and all the best! The sping is here, soon no more heat needed :)

Great job Alan, although it did look complicating at the start, it become apparent that it really was a doddle once you had everything in order. (Well I think it was) I was amazed at the price tbh It almost made me cough on my chicken sandwich. Maybe this time around you wont leave it to long to inspect and give it a once over as you would a gas heater boiler. And the extra pair of hands came in use too. Well done Peter. 🖖👍

@MyNarrowboatVenture 6 месяцев назад

It was really a straightforward dismantle and re-assembly. I don’t feel there’s anything to inspect, it is to my mind a case of, if it’s working leave it alone. Used heaters are £500 to £800. There are copy parts available cheaper but I prefer original 😀.

@castingshadows282 6 месяцев назад
