| How well does it work with Instant Gas Hot Water systems? |

You can test the kind of temperature variations you might expect by turning your hot water on and off manually. If you wait 30 seconds, (the time it might take to shampoo your hair), does it cool down a tad, thus creating a drop in temperature for a moment? As for wear and tear, you should phone the manufacturer of your brand of gas heater system to discuss this very point. Is the lifespan of your gas heater based on 'hours of use' or the number of times it turns on and off? If it's based on the hours of use then the Every Drop Shower Saver® could extend its lifetime.
Rinnai technical assistance (http://www.rinnai.com.au/) said that when you flip the water flow back ON the temperature would be near what it was and then it will likely drop a bit as the cooling water runs through and the unit heats back up. As for life expectancy, they don't expect it would affect the life of the unit because the unit in their tea room has been turned on & off frequently over the past 10 years and still works perfectly. You should have a similar conversation with your particular gas hot water system manufacturer. The Every Drop Shower Saver® does not work with the Bosch Water Wizard 13P but works fine with many others, so worth checking. NOTE: The folks at Bosh pointed out that, because the gas only turns back on when the water begins to flow again, it is likely that you may get a foot-long section of pipe of un-heated water surprising you with a 'cold slug' of water when the Every Drop Shower Saver® is flicked back on. It's difficult to predict if this is uncomfortable or subtle. Only experimentation will tell but that is why you should first ask the manufacturer to learn of any unique qualities to your model. The two key questions to ask a plumber or hot system manufacturer would be: 1) Does frequent stopping & starting of water flow effect unit life? 2) Does the potential for back pressure due to joining the hot & cold feeds at the shower head present any issues with their system? |
