Well it was lucky I didn’t sell up just yet as had a bit of a setback last week , turns out that mild steel is not man enough for the job!
I had the exhaust wrapped to keep the heat in , it worked too well and blew out the welding on the pipe seam !
I have now built another one with an outer coil added to help cool the exhaust and do away with the heat wrap , will be testing today with feed temps and heater temps after warm up
I also am having a 304 stainless version made up , this should be a step closer to being able to sell a few of these things!
