My 50 liter hot water
tank has, theoretically three sources of heat:
1. An electric
immersion element running on 230v shorepower or generator
2. A loop to the Eberspaecher central heating
3. A loop from the propulsion
engine's fresh water cooling
I like heating
with the immersion element because the water goes up to near boiling temperature and lasts much longer, since it is diluted before use.
But now that I am off shore power
and on a midriver pontoon, I will have less opportunity to make a tank of nearly boiling water.
My hot water doesn't heat up from the main engine's cooling
circuit. What could be the problem? Can anyone suggest a list of troubleshooting items?
Only thing I could think of was:
1. Airlock in the pipes -- bleed.
2. Faulty valve -- replace.
3. Faulty design -- hoses too long for the engine
fresh water pump to provide enough flow. Install electric pump
Anything else to check? The engine
is a Yanmar
4JH3HTE. The calorifier
is around the same level as the engine, about 4 or 5 meters away.
