Hi all,
I don't know if anyone has had a similar experience, but I'm having problems with my Rinnai water heater.
The boat hasn't been used for months, and now the water heater isn't firing up when there is a demand for hot water. It worked fine before. The pilot light works fine, and I have temporarily removed the water filter in case it was blocked and affecting water pressure. I have also swapped the gas bottles to make sure that the gas pressure is sufficient. I installed the unit a couple of years ago, but I've probably only used it a dozen times, so it seems hard to believe that any of the components have worn out!
Now that I've ruled out the 'cheap' solutions I'm guessing it's going to require a more expensive one. I've looked quickly at the spare part prices for these things and they seem pretty high. Can anyone suggest why the unit isn't firing up when I turn on the hot tap? I guess one reason is a split diaphragm, but why would it split after so little use. I should confess that I haven't drained it down until now, so maybe frost has something to do with it, but we haven't had any really hard frosts in the meantime, and in addition I haven't noticed any leaks.
Thanks.
Oh, just one more thing.... Is there an easy way to check the water pressure coming out of the tap? It doesn't seem great.... Thanks
