Oh, and we always use Beldon twisted pair wiring for sensors. It is the industrial standard.

No, I'm not using O2 barrier tubing. It's a closed loop system and the water heater will be dedicated, and the manifold has an air eliminator at the end of the return side, so air that the tubing accumulates through expansion and subsequent contraction of the water should be removed by that to avoid corrosion. Do you figure I still need a non-ferrous pump and fittings?
I'll check out the Vertex water heater - the significantly higher efficiency would definitely make a condensing one more attractive, but they are usually so %$#^ expensive compared to regular ones :P
Thanks for the info!
