Water Heater exchanger on 3208 Cat

[Capt. Jon]

Wondering if anyone here has ever tapped into a Caterpillar 3208TA cooling system to supply heated coolant to a water heater exchanger. If so, where did you tap into for the engine for outlet and return?

Thanks

One line comes from aft stbd side of port engine. Other looks like off water pump behind the alternator. My PO installed with isolation valves. Good idea. Hoses look small and heavy duty and have that chafe wrap. Now I know how it is all plumbed.

Dan, awesome pictures! This showed me instantly what I needed to do! Went right to the spots and the previous owner had plugged the fittings coming from the same spots. Looks like he used 1/2 pipe fittings. Now all I have to do is get some brass isolation valves. Like the way your PO added the extra valve for block draining. Thanks so much for taking the time to help me out!

Which hose goes to water heater inlet valve?

Hi,

In hooking up our new Raritan heater, the water heater clearly wants valve A to be in inflow FROM the engine,and valve B to be the outflow TO the engine from the water heater. We can't figure out how to determine which hose is going to flow INTO the water heater. How would I figure that out?

Thanks!
