hi I am new to this site but after some help please I took on job fitting out a narrow boat for a customer and confused when it comes round to plumbing the calorifier in
I have been researching the cylinder and so far I have got that it is a telford twin coil calorifier being feed from a webasto heater and also running off the engine I get the basics of how it works twin coils heating the tank up cold feed at bottom flow and return for central heating then I get confused to were the hot water is surpose to being comeing out please can someone help before I have an internal flood or melt down and maybe the best way to plumb this system up valves, expansion tanks, regulators etc I have uploaded the cylinder any diagrams of how things works makes more sense to me then technical terms many thanks
