Default Getting hot water to my HLT

I have a tankless hot water heater that has a flush kit on the bottom. I can hook a hose from my charcoal filter to the cold side and get filtered 140* water out of the hot side. The problem is, how do I get it to the HLT? My RV hose can't handle the temperature. I found a hose at the local hardware store that is for hot water but it says right on it, not for drinking. I tried it anyway and the water coming out smells, like, well, a garden hose. I did a search here and the general consensus is that smell and taste won't improve my beer.

The only thing I have thought of is silicone hose but I am not sure how to put garden hose connections on it and I think the pressure would be bad for it.

Someone here must have solved this problem before?

It is only 15'. I certainly could do that. I was just trying to keep it a little simpler and mobile.

Can't get much more simple than pex.

Silicone tubing, Tygoprene XL-60 or Superthane with the appropriate fittings? Probably the easiest way.

Garden house fittings and big silicone hose. Or pex. . . Or copper, but then you might as well just turn on your tap. . .

The high temp silicon hose we see at LHBS or on homebrew websites is only rated at 30 psi. Your house is probably regulated much higher. You can find 1/2 inch hose barb garden hose connections at your local hardware store. Make sure you control your water at the source, don't overpressurize that hose!

Easily controllable with a water pressure reducer or a valve though. Tygoprene is a bit stronger - Superthane might be a better choice.
