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 system
3. A loop from the
propulsion engine's fresh
water cooling circuit.
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.
