Hi,
Please forgive the on-topic nature of this post...

I'm about to hook up the "domestic" Hot-water from my new engine (ie
use the engine's cooling water to heat the domestic water). I'm using the
same hookup as for the old engine, but there are two hoses - does it
matter which way the water goes? (ie is there a distinct "inlet" and
"outlet") The HW heater is really hard to get at, and I didn't mark the
hoses before I unhooked them.
