saltnpepper 0 Report post Posted March 3, 2012 hi! i am currently using a Rinnai water heater reu-8cg. i have seen raves about this product... BUT! has anyone encountered condensation or too much water vapour escaping from this water heater during use? im asking becuse mine fill the whole laundry area with water vapour, resulting in moisture/droplets all over the pipes, ceiling n wall - within a minute after water is switched on in the shower.i have city gas people coming over to look at what was wrong. so far, the water heater was relocated lower, a cover built to prevent (another problem) flame being extinguished, an ugly diy 'fabrication' built over the top of the heater... but nothing is working. its so serious that the whole ceiling is wet wihin minutes. am i the only one with this problem? we may have to get a new heater, but does all gas water heater have this problem? pls help n contribute your experiences, thank you much much!

yoongf 11 Report post Posted March 4, 2012 Your symptoms sound like steam coming out of the water heater? like a kettle?Water heater suppose to heat to only max 60 degree, not to boiling point.Perhaps this model got a rapid heating phase.. where there is max heating.. and water boils over too fast?I not familar with gas heater.. but it really sounds like the regulator is set incorectly resulting in overheating.

yoongf 11 Report post Posted March 4, 2012 Come to think of it.. usually such heater got a pressure relief valve to release excess pressure when over boiling. Perhaps yr relief valve is stuck open and allowing steam to be vented out? Share this post Link to post Share on other sites
