I am surprised by all the issues mentioned in this forum. Looks like some are installation issues rather than product issues. I have had my unit since 1999 and only had 2 service calls - both to replace the pilot light thingie (same issue I have with my gas ducted heater). I only came to this forum to research hot water alternatives for a friend, and the continuous flow Bosch & Rinnai look good for domestic situations. Hope you get your issues sorted out :)

I was very surprised to find my Rheem Stellar Gas Domestic Outdoor Water Heater needed its anodes replacing after less than 4 years. The suggested time (as written in my booklet) says 10 years but could be less depending on the type of water etc. But still, that would be approx. 7 years before I would have needed to replace the sacrificial anodes. Looking on line at the new revised booklet put out by Rheem I see they have changed the amount of time to 5 years. Hope Rheem can give me a proper explanation.

I installed a new Rheem Stellar 330 exactly 3 yrs and 3 weeks ago. 6 weeks ago the pilot light started to go out inexplexibly and now it will not light at all. After 2 emails and several calls having to queue in the phone system, warranty only covers tank not parts or labour beyond 12 months. $143 for 30 mins and $28 per 15 mins thereafter plus parts. Is that the expected life of the parts of a Rheem. What use it the tank if the rest of it fails seriously !!!! Will never buy Rheem again!!! 3 yrs is a ridiculously short life expectancy for any part of hot water system.

Useless warranty
