Transferring High Pressure Hot Water

[foamous]

Hey Folks,

I recently installed a tankless hot water heater to replace a defunct tanked one. When I installed this unit, I made sure to include an extra valve on the hot water outlet thinking that I could utilize the on demand hot water to cut down on the time it takes to heat water for mashing, etc.

I'd like to be able to run a hose/tubing from this hot water outlet about 30 feet to my garage where my brew equipment is located but I don't want to install anything permanent. I'd like to have a solution similar to that of an outdoor spigot/water hose that you can conveniently attach/detach when in use.

Does anyone have a suggestion for what I could use that can handle high pressure (household pressure is around 50 at the outdoor spigot) and high temps up to 150 degrees? Your help is much appreciated!

Hot water hose? http://www.amazon.com/dp/B000IO6PKC/?tag=skimlinks_replacement-20

I wouldn't trust that to be food grade. Look at silicon hose from morebeer.com or brewmasterswarehouse.com. Temp rated higher than your source I'm sure.

Good point. You'd need reinforced silicone to handle the high pressure, though ...

Will this work? http://acehose.com/potable-water-hoses.htm

Those look to be good enough in that they can move your hot water. You will still need to heat the water more for strike or sparge temps. If using a counter flow chiller, they may not be suitable for reclaiming water from that chiller because discharge water from a cfc can be pretty hot if done properly.

Hey guys - the hose from acehose may just be what I am looking for. I just want to be sure it's safe and that it doesn't impart any altered "taste" after the water runs through it like what happens with a regular garden hose or something.

I e-mailed Swan Hose from dutchoven's post about their rubber hot water hose. Here's their response:

Probably safe, but who knows what other flavors might come out of it.

Coming from a plumber... I wouldn't soft line anything more than 5 ft. It's just askin for trouble, and way to many things could go wrong to risk doing it at that heat. 150 will burn like hell.

I'd do copper. Sweat it to a threaded connection so if all else fails you can cut it all out, unthread the last little piece, insert plug... Recycle everything and get a few bucks back... Not to mention the peace of mind.

If you must soft line it make sure there's a water shut off a good distance away from it!
