I’ve had my boat from new, built by stoke on Trent boatbuilders in 1998 and fitted with eberspacher which ran well but finally failed. Decided to replace it with Webasto as it is more modern with good reputation. New heater installed by Stokeboats and connected to existing plumbing system . ( pipe work, radiators, calorifier etc.) heater starts and puts some heat into system but then shuts down. Diesel feed has been bled as well as water system. System incorporates header tank and is identical to system when Eberspacher was fitted, in fact only the final connections from pipewok to heater was changed.
Any ideas please ????
