My hot water heater keeps going out on a daily basis.Its less than a year
old. I can relight the pilot and it lasts 5 or 6 hours.What should I look
for? Any suggestions would be greatly appreciated.
First off I gotta ask it. Why are you heating hot water? Just jokin.
Could be the thermocouple is on the fritz. If the heater is still
under warranty, call and havit replaced. If it isn't, it's not a hard
job to do and thermocouples are fairly inexpensive.
In my last house I hooked up a hydronic heating system to my water
heater and used that to supply hot water to zone the rooms that I had in
the basement. It worked great and I'm thinking of adding a similar
system to this house but I might go with a tankless heater in the
future. My question is does the tankless heater stop heating the water
when this loop is eventually filled? Does it matter that it will be
reheating water? I guess I want to know if this could be done safely?
Tankless heaters have a T-stat on the outlet, otherwise, the output
temperatures would vary wildly relative to delivery flow rate and
Part of the trick is ensuring that the loop _includes_ the T-stat
of the tankless.
So, conceptually, it'd work. And many hydronic systems work precisely
However, before blindly picking any old tankless, I'd check either
with the instruction manuals or a professional whether _that_ specific
unit is appropriate for hydronic heat. Having a professional
size/design (or give you specific tips about) the system is a
good idea in any event.
And I'd most certainly _not_ choose an electric unit.

Before you call for service, make sure you have gas. At my last house the
gauge failed on the propane tank. The hot water heater was shutting down a
couple of times a day. It would always relight. The serviceman replaced the
gas valve, an expensive repair. A couple of days later it was obvious the
tank was empty. The serviceman had only checked the gauge, not the pressure.

I would call a service man or where you bought it. I had a problem like
that about 5 years ago. The burner holes were clogged
and even though the pilot light was off. There was a small amount of
gas escaping and building up. The repair man said he was glad I called.
He said that maybe the next time the pilot kicked on my house would be
He had to replace the burner. the water heater was only 2 years old. My
propane is piped in and on a meter so no tanks outside.

Is the gas supply OK, ie if either the water heater or the furnace go
on, do they get enough gas? I've seen failing underground gas pipes
that are leaking wind up with water in them that blocks the flow of
