Webasto serviced again, Coolant good mixture, pipes all connected as should, webasto bled, rads bled, fuel pumping, webasto in out water/coolant pipes rearranged aswell as webasto repositioned. Still smoke on start up this time from top of air intake tube connected to webasto... Any ideas

Hmmm, okay well im guessing its not quite 50 50 anyway as i only topped up last time in the header tank with a mixture of 50 50.. Whatever was in the system already... Mainly water i assume... I would say its more like 60, 40 in essence... Cant be 100% but when i drained it off the mixture was not dark blue... Lighter shade... Anywayz.. Real annoying

Hi do you have a number of an experienced webasto engineer for narrowboat? Hi do you have a number for rhe guy who serviced your unit, installed it etc?

Yes i drained all but the radiators

Any idea how to loose a potential airlock in the system? Im not a plumber, lol. And value, what kind of valve are we talking about... I didnt switch any value while removing the unit for refurbishment purposes... Only thing switched was the fuel line off so didn't leak diesel everywhere... 🫡

Why

Staffordshire, penkridge to be exact

My heating system is a Webasto Thermo Top C, it runs x2 radiators and x1 towel rack (rad)... System uses a 50/50 mixture of antifreeze & water to run through the rads. The system is connected also to a colirifier to heat water... Currently my webasto was reconditioned as the inner burner was clogged with burnt fuel. Im guessing when the boat was taken from the water it drew dirty fuel from the bottom of the tank. Webasto has been reinstalled by myself in the engine bay, all pipe work is 22mm with 15mm T offs to rads so within recommended frame work. Webasto turns over using when using control unit an fires up, inline fuel pump seems to work... Could feel coolant/water circulation through pipe work to unit. Webasto goes through start up process makes all usual noises but eventually sounds strange. Slight smoke from unit near exhaust and unit gets hot as hell. I dont trust leaving it on in this state. Even bled rads and air seems to be released. Right now i am confused with the whole set up and dont undertand why it is not working. I thought could be electrical related issue but usually a webasto would not even fire up if it doesn't receive its 12v's so again this is why I'm stumped... Any ideas or know anyone good with these systems? Getting to winter soon and would be nice to have the rads working
