10 dollars... with 115 shipping LOL... irony there...
Thanks for the help ben. so DC it is. Ill talk to my friend to see if he cant get a surplus DC power supply. It shouldnt be too hard to come by.
Heat sources
Secondary Heat from shunt - handled with sealed insulating res that shunt is placed in
DC PSU - Hot air vented out window through ducting system
Radiator exhaust and seondary heat loss- have rad exhaust also vented out the window.
Is there any more heat sources? I the pump could be considered, but i think I will use a 50Z for the radiator tests as I will get plenty of flow from it. the iwaki would be excessive as non one can get the flow rates that an iwaki would provide given they had an actual loop. So with that said the 50Z's heat dump is a small 8watts into the water with about 1-2 watts into the air. This will be a constant with all tests done so i think this heat source can be ignored. If I am wrong in my thinking here please lmk.
