ACI was an interesting conference with a lot of great vendors exhibiting, but one had me stumped. The company was called ShowerStart & they have a product where you turn on the water & as soon as it hits 95 its slows the flow to a trickle. Once you hop in, you pull the lanyard & essentially you have hot water & saved a bunch that would have gone down the drain.

Personally I like recirculating systems & consider water the next big thing to watch (which for some parts of the country it already is) but would love to hear your thoughts - is it something you would recommend / even use yourself or just a gimmick?

Jim - The last iteration of the chilipepper is what you have heard about. It has been reengineered and is no longer loud and has longer lifespan. I dont know how you can think it is difficult to install. All you do is disconnect the two shut offs and put it between the two. The hardest thing is access to an electrical outlet which may have to be installed if not present, which is the same as the metlund product. Chilipepper was actually created by the guy who originally designed the Metlund system. It is actually on the order of three to four times more powerful which moves the hot water faster. Its also about 4 times less expensive as the metlund and can be self installed by anyone that has any home improvement know how. I'm not affiliated at all, I have just researched this topic extensively and have experience with both. I dont like paying 4 times the amount for a product that does the same thing. The metlund could very well have the durability edge but even if the warranty didnt cover your issue, you could buy 4 more of them!

Thanks for the re-iterations. Early in 2011 a friend, also an energy auditor, slipped a chilipepper into her plumbing. And OH what a relief!

Water bills dropped; kids love it. Even the noisy iterations had value -You KNOW when it's done and the water is hot and waiting because the racket stops! Kids LIKE that. Like when the doggie stops barking, we wag into the shower.

Happy campers are made of this.

One of the obvious problems with the device... is the use on installations in which the owner has previously installed thermostatic valves in the showers.  I use Grohe's thermal (Grotherm) controls.  We generally set the temperature at about 85F and that's where the water stays...  No value in the kit above.   For long runs using a chilipepper using either a dedicated return or the cold water return - works great.   I trigger my chilipepper when any of the bathroom light switches are turned on.  The recirc pump is located near the cluster of bathrooms.   Very little waste water and the shower temps are extremely stable.

Interesting side note... since I'm used to taking cooler showers - that seems to have caused some problems in a few of the German hotels that we've stayed at.  Most of the 3+ star hotels also use thermal controls for the showers.. and I'd set the show temp at about 25C-30C.  Two days in a row we had maintenance people coming up with immersion thermocouple probes and meters to verify the correct observation of the shower... because the cleaning staff noticed the temp was set at 25C instead of the higher temps that many of the Europeans like...  :-)
