It sound like some one hammer my heater pipe, and it start when the
boiler is burnning. it get very loud, "crank crank crak"
Any one know how to fix this? or something is wrong?
it didn't happen all the time when the system is kick in, but most
likely at night. I have always wake up to check what happen, some time
give it little more water the cranking sound will go away. The
cranking sould is from Heating boiler, and go all the way with pipe to
sound like return water pipe or something.
Need help, winter is here again and need sleep for the whole family.
sounds like something is wrong. hire a qualified heating repairman for
your system [is it steam? is it hot water?] look over your type of
system and show you how to perform annual maintenance. there are water
controls, gauges, and expansion tanks to learn about. also there are
controls and sensors that limit your system from overheating which may
need adjustment or replacement.
Deposits built up on the bottom will do that, the solution is a new
boiler. If you had maintained it from leaking without adding all that
makup water you wouldnt have built up deposits, Depending on unit
cleaning may help.
the boiler is about a year old, new just install not long ago.
"give it little more water" mean i add some more water to the tank and
the sound stop.
I have 2 zone, upper floor is steam heat and base is hot water heat.
Steam system... sounds like "water hammer"
look that up
if it is a single pipe system the pipe needs more pitch or you need a
return pipe also...
the return moving condensate and the forward moving steam are colliding
in the pipe..
the noise is around the boiler pipe i belive, not 100% sure it is from
boiler or pipe.
it is dual pipe system, one go out (steam/hot water) and return piple.
the noise 95% i belive is somewhere near boiler return pipe or boiler.
Because the noise follow the return pipe and making 2nd floor with
I try to turn the basement heat(hot water) higher than the upper floor,
and release the tank water until it is look clean. it seem goes away
little, the noise isn't that loud.
the basement heat most time wasn't turn on, due to the basement temp.
is keeping well. Maybe the water pump wasn't pump any water to make
the hot water to cycle to the tank.
what could be wrong? will see if the noise come back or not.
Thanks for all your guys help, aleast i can have good sleep during
Thanks giving night.
and happy hoilday to all.
Could be water hammer. The steam may be carrying slugs of water that hit the
pipes and make rather loud bangs. This mostly occurs during the start of a
cycle when condensate is laying in the pipes.
If it is a steam boiler, don't do that. Is there a sight glass? Is there a
mark for the water line? Never go below the line or the boiler can overheat
and do much damage. Serious, expensive damage.
If you are not familiar with the workings of the boiler, call a pro and let
him check it out and show you how to care for it.
Don`t just "add a little water" when you feel like it, go by the gauge,
and dont add cold water to a hot boiler. You need someone to go over it
, you must learn how to operate it before you possibly ruin it.
i didn't turn up the pressure, i have 2 zone (basement and upper floor)
and the basement hot water is using a pump to cycle the water i bleive
( which i have see a device near the boiler look like pump)
the pipe around the boiler has change , and also partial of the return
pipe too. there was a leak on pipe before, which has been fix.
If it is pipe hanger, how come the loudest noise is from near boiler?
i do call people to check, which the boiler didn't show some "respect".
When they come and check, the boiler keep quite and system just look
fine as new. Just can't keep paying for visite for nothing.
now i belive it is more like you guys say water hammer, because it is
only ON when the heat is coming.
BTW: i say turn higher temp. on basement which i want to cycle the
water that is in the pipe. Because the basement most time heat is not
on, which pump will not cycleing the water.
So far so good, as today the hammer "music" is not coming every night.
If it do come, it go away faster than before. I will do more cycling
the water to clean up the pipe.
Thanks for all your people helping me, hope this info will be helping
other water hammer victims too.
