My 10l calorifier (Surejust type) part of an eberspatcher hot water/heating system has sprung a leak. I’m currently in Spain a week away from ferry booking home. Any idea if it’s possible to seal the leak and with what, enough to get me home?
 
Put some bars leak through it and let it seal, or any headgasket sealer will work.
 
I’d have to fill the complete water system to fill the calorifier in situ, so doesn’t seem like a good idea to fill with headgasket sealer. Otherwise means removing the hot tank, which may not be practical whilst on the move.
Any ideas on sealing from the outside of the tank?
 
Have you had a good look to see where it is coming from? If like mine there are the pipes from the Eberspacher/engine coolant going through the coils then all the domestic hot water connections. Then of course the pressure relief valve. Lots of places you could have a leak apart from the calorifier itself. When I had problems it was one of the John Guest connections on the coolant pipe side that had a slight leak

Edit: turned out mine was caused by one of the stainless holding down straps breaking letting the calorifier move a little
 
Photos please. I don't have that system. Is the tank pressurised ? Constantly

If not watch kingin it. YT they welded there tank after Norways cold, bursting tank.

Full story- I realised something was wrong when we parked up in the aire in A Rua on the N120 between Ourense and Astorga, the pump kept recharging the system. Discovered water seeping from a split in the calorifier insulation, so drained the system to have a dry night. Realising there was a hardware/ builders merchant on the high street 5mins away, headed there in the morning. They didn’t have the JB Weld solution but something called Pattex Nural 27, you can buy in uk. So bought that for 17.95e and headed out for Astorga (must visit place) parked up in the aire at the bull ring and set about cutting away the insulation from around the split. Nothing to be found, so filled the system, water coming from nearer to the end of the tank, so cut more insulation away to reveal 3 or 4 tiny pin holes in the end cap of the tank where it bends over the body of the tank. Each hole spurting a cotton thread jet. So mixed the two tube sealant and applied a good layer over a holed area and left to cure. Went out for an evening of bar crawling in Astorga to celebrate (all those free tapas with each beer) what looks like a good job. Filled the system this morning, put eberspacher on for an hour and two showers, no leaks, seems like a good fix to get us home clean. It’s a 21yr old motorhome so thing go wrong now and then!!
Thanks for offer of help from Girona and JB Weld idea.
