Heater Not Working ~ Most Common Hydronic Heating Heat Problems

For heat use what you want to do is turn both
of these handles so that they're in line with the pipes. Perpendicular so you can hear the water start
to cycle through. What you'll feel is you'll feel the line start
to get really hot. This one's getting hot already. You also want to look and check for any leaks
or anything funky going on. One common problem with hydronic units. Not this particular set up.

Different set ups will have a purge line where
you hook up a hose to it usually inside the air handler you will hook up a hose and run
it to a bathtub. You need to purge the air from the line by
opening up what is called a gate valve. You'll undo the twisty twister to open the
gate valve. One tip with gate valves you don't really
want to cinch them open or cinch them closed when you close a gate valve. You want to close it gently. When you open it you don't want to open it
really tight towards the end.

You want to kind of leave it especially on
water heaters. That will help prevent the gate portion from
sticking inside the valve. One common problem with hydronic units that
have a circulation pump at the hydronic unit especially units that are in the ceiling is
there is a little cylinder pump motor and that pump motor often gets jammed. A little rock or something gets stuck and
what you can do is just tap on that if it gets stuck go ahead and either tap on it you
know either with your palm like so and tap on the valve itself or just lightly with either
a rubber mallet or kind of the rubber back of a screwdriver and just tap it. Allot of times you will hear it just free
up whir and than cycle through, cycle the hot water properly. Those are kind of a common problem with hydronic
units in addition to occasionally needing to be purged. My particular system is on a boiler system
and a recirc pump and I can purge air at the recirc pump but mostly usually not needed
on my particular set up but each set up is a little bit different.

Has it's own little quirks. Usually around the beginning of the heating
season you'll get all your no heat calls. Either needing to know how to turn the valves
on like this one or how to purge the air to keep the unit heating..
