The first five or six months in our new home, whenever we took a shower
or washed dishes or whatever, the water heater (gas) would click on for
about ten minutes or so, in three minute intervals. More and more
lately, over the last few months, its been clicking on for maybe ten
minutes but in more and more erratic intervals, like sometimes a short
20 second interval, and then like a 2 minute one, and then 6 - 15 second
intervals in a row. Really weird. We've tried messing around with the
temperature a bit but it doesn't seem to affect it. Any ideas?

Does the control look like:

(That deals with a recall. Those controls don't usually
cycle frequently; they have a wide hysteresis. If you have
a Power Vent or Direct Vent a different control would be used.)

Is the heater still under warranty?

Jim

Should still be under warranty. Get the model and serial # and call
the manufacturer. Sounds like a bad valve/control unit, which is
pretty easy to replace.

If you still get hot water when you need it, I wouldn't worry about it. You
may just be paying too much attention.
