OK I kinda figured that, but what does the heating electric, NG?, do you need copper or will PEX work?
Cheers

either - I have NG -- note as per a post above that the Natural Gas ones use electric sparking devices to light them off - so if there is a power failure, you get no hot water. If you had a tank water heater, then you'd get a tank full of hot water, and over some hours would have a tank full of lukewarm water (i.e. there is some buffering in a power failure).
Either PEX or Cu pipe can be used. I insist on Copper b/c PEX has been shows to leach some potentially non-healthy chemicals into water. Hot water accelerates that. It depends on how much $$ you put on potential health risks. As with other such things, the risks are much greater for a pregnant woman or for children than for an adult male. And if you are 85, then why bother? |

ok, the thing rocks! i finally got around to hooking up the remote controller, and turned the water down from 140f to 120f. i have endless hot water, and the thing operates at very low flow. i can trickle hot water from the faucet.
new copper lines ROCK X2! i can drown in my shower now!!!

r53e. i mounted it externally. it needs it's own dedicated gas line, a power lead, and water of course. it made sense (financially) to install it near all the utilities.
the unit has computer that puts out error codes if something happens. very cool.

Thanks.
And fwiw 120 is absolute minimum for clothes washing. Bleaches barely work at that temp etc. (Hangover knowledge from a year selling commercial laundry chems). Ian

I use Rinnai r75Lsin . Here's my review - Rinnai R75LSiN .
The same site (Tankless Water Heaters - Reviews, Tips, Recommendations ) has a calculator for various parameters of the water heater. |

Also, besides saving you up to 25% on energy costs, ENERGY STAR gas tankless water heaters are one of the qualifying energy-efficiency improvements that are eligible for a tax credit (in the U.S.) IF you make the change January 1, 2009 through December 31, 2010. If you're a U.S. resident, you should read over the tax credit info for 2009-2010 before you choose products.
