I am having issues with my hot water
properly, even after 4 hours of motoring (I had the boat yard replace some rotten lines, never worked properly after that).
My system is as follows
I have an ardic diesel
heater in the aft lazerette plumbed into my freshwater engine cooling
loop. The system uses a heat exchanger
to provide forced air heating
in the cabin
. The heat exchanger
is installed below the port settee.
The hot water
tank is installed forward of the heat exchanger under the port settee also.
The proper route
for the piping then is diesel
heater -> engine
-> hot water tank -> ardic heat exchanger -> diesel heater right?
Now with cold coolant
, the thermostat on the engine should be closed so flow would be prevented through the engine so a bypass line is required (if I want to use the ardic to heat water and provide cabin
heat). If you do this then I think you need a one way valve in the bypass line to make sure the engine doesn't just cycle the coolant
This is my thinking on the system but it just doesn't work. Does anybody have a schematic that I could double check my arrangement against?
