My newly purchased 2006 boat
has a Kuuma 6 gallon water heater
. When we first ran the hot water
, it had a slight orange color and a definite smell (the cold water is fine). I didn't think much of it since the boat
had been sitting for awhile, after all. I ran a lot of water though the system and while it got a lot better and clearer, there is still a faint smell to it no matter what I do.
I searched the forums
for people with similar problems - commonly, most other people reporting a smell say it's a sulfur smell that requires replacing the anode, but I haven't seen anyone mention the orange water color which could have been - rust, maybe? And the smell is so faint now, honestly I'm not sure if it smells like sulfur or not.
Someone in my marina said it could be leftover antifreeze
from winterizing, but I have flushed a lot of water through it. Another person suggested putting a little bleach in the system, but yet another old salt
in my marina says that would be terrible for the hoses and sealants. Any ideas how to fix this other than replacing the heater
? I am certainly open to the idea that the now 13 year old heater is just too old, although this boat was lightly used in its lifetime.
