Hi all, We have recently completed our maiden trip in Delta Queen, bringing her from Ventnor Farm Marina to our home mooring on the Coventry Canal. Excellent trip, and apart from a heavy shower whilst descending the Hillmorton locks brilliant weather. On the trip we noticed that the radiators were getting hot, even though the Webasto heater was switched off. When we got to our home mooring I looked at the calorifier plumbing connections and think they are plumbed incorrectly. The calorifier is a "Surecal" and was replaced in January. It has 6 connections. Lets call them 1 to 6 starting with 1 at the top. The bottom one (6) is the cold feed in, the top one (1) the hot water out, and the other 4 are the twin coils for the engine cooling circuit and the Webasto heater circuit. I think that the two coils are connection 2 & 3 and 4 & 5. Currently the engine circuit is connected to 3 and 4, and the Webasto heater to 2 and 5. I think this connect the engine and the Webasto in series, hence the hot radiators when the engine is running. (The rads also get hot with the Webasto only on). I think the engine connections should be on 4 and 5 , and the Webasto heater on connections 2 and 3, as this will allow the engine to heat the hot water, but not the radiators. Am I correct? Once I have identified the correct connections, how easy is it to change them? I presume you have to drain the calorifier and also the engine and radiator circuits. If they are plumbed incorrectly, my first port of call will be to ask the company that installed the calorifier to sort it out free of charge. Thanks in advance for the help[. Alan
