1.0 out of 5 stars Bosch Tankless Water Heater, August 30, 2008

This review is from: Bosch 1600P NG AquaStar 4.3 GPM Indoor Tankless Natural Gas Water Heater (Tools & Home Improvement)

This product worked fine for about 10 weeks. It then started shuting down while in the middle of the shower. Turning off the water and then turning the water back on, the unit would then start delivering hot water. I contacted tech support numerous times and they say nothing is wrong with the unit. They want me to send pictures of the installation, have a gas tech come out ($80.00 my expense)and check the gas pressure on thier side of the gas regulator. The last tech I talked to said to turn the gas shut off valve almost off and see if that helped. It does help but did not fix the problem. Think about it, use your gas shout off valve to make it work right. He said that my ground water temp was probaly too warm (71 degrees). They will not tell me in writing what they require of me to get the unit replaced or what they deem wrong enough to replace the unit. Apparently working fine for 10 weeks and then sending cold water during your shower daily is not enough.

Have had Aquastar (Bosch) tankless heaters in both my main home and a guest house for ten+ years in a rural area. Never had a problem. Have used a Palomar in the lodge in Alaska for 20+ years with never a problem. Recommend them to keep costs at a minimum not using traditional water heaters and paying the costs. Am surprised the other reviewer is having such problems.

I had this water heater installed in '07, and it has been a money saver ever since. I love that it has a standing pilot, when the power goes off, I still have hot water. No trouble with it. Purchased the unit on sale, took it home, when I was ready to have it installed the plumber gladly did the work. I have never been without hot water.
