Plumbing / bleeding air from system

« on: October 25, 2015, 05:48:46 AM »

I made a post this week about adding a hydronic heater in my garage.  I added another loop using another circulator and another return to my stove.  Thanks to RSI for all the help.  I put all the stuff in yesterday fired up stove and can hear lots of air in the system.  The new loop I added I put in a drain valve where I can bleed on the return side.  I bleed the air out of that loop and its working good(may have to bleed one more time).  My question is on my house loop.  I put a new circulator in(replaced a 15-58 with a 26-99).  I have only one place where I can bleed that side and that's on the return at the stove.  what is the best way to bleed my house loop?  I'm thinking close the return let it build pressure for 30 seconds and open the ball valve.  is that thinking correct or totally wrong.  I jut don want to burn up the new circulator.  another question is the 26-99 louder then the 15-58 or is it just the air in the system still.  Hope I explained it ok if not let me know and I will try again.

Thanks
Adam

I was thinking the tee would be in the 1" line after its returned thru the heat exchanger.  I know sounds complicated  but I'm hoping it will work.  after the house heat exchanger and on that return line I was thinking of teeing into that to get the water back to the OWB.  Hope I'm not confusing u at all.  if I am I will draw a diagram and post it but I'm sure you understand it.
Thanks.

The pex lines going inside that are unused is 3/4" but my main heat lines for the house are 1".  I have more ports available on my OWB yes but the other line that I would use for my hydronic heater return is used for my water fill.  so not a good idea to tee in the return then, or are you saying use something besides pex for the tee?  what would that cause if I did?  Thanks again

Ok I understand it now.  So looks like I'm adding a pump outside on the OWB this weekend.  Can I tee into the other return line or will that cause a back flow?  I'm not worried aabout it giving off too much heat as I have a drafty garage door.  Thanks a lot RSI.

add the other pump outside on boiler and keep in running 24/7 and controlled inside or have something control the outside pump?

Will hooking into the return side add more head pressure?

both great ideas and I'm feeling better in which direction I'm going to go.  As RSI said with adding a second loop, does that mean another circulator on the OWB? or just using a Tee in the supply line coming in from OWB and a circulator?    Because I have the ability to add another circulator outside and I have extra pipe already in the ground and ran inside.  My garage will never freeze.  Bare with me through this because I'm trying to understand it all and understand why we did it that way.  So I appreciate all the advice so far.  Thanks and have a good day.

so your saying t in the return side and use the return water temp for use with the hydronic heater?  That seems like a good idea.  so I would be teeing into the return line twice correct?

I hope all the professionals will chime in with some much needed advise.I have a reznor hydronic heater that is brand new and I would like to hook up in my garage.  I was thinking of teeing off the feed line coming into my heat exchanger and using a monoflo valve.  I have a separate circulator for this unit and was unsure if this idea would work.  my other option  is adding another zone off my inside furnace.  Will using the monoflo valve setup affect my house heat?  Will the monoflo valve idea work at all?  Thanks in advance.

When you guys say "coil cleaner"...do you mean the stuff that is typical used externally on evap/condenser coils?

And if so, do you circulate it full-strength through the pump or diluted?

Yeah im wondering the same thing. also since I don't have shutoffs im gonna have to make adapters right or just put ball valves in when I reassemble?

All my manifolds have added drain valves with ball valves to isolate the heat exchanger for flushing, I use commercial coil cleaner and a liberty pump, five minutes on each side, flush them with clean water and they are as good as new!

What is the name of the cleaner? I don't have drain valves on them so id have to remove lines then flush.

Getting ready to fire up the boiler within the next few weeks and I wanted to flush my plate exchanger.  Can I use a pressure washer?  Compressed air?  Water hose?  and do I need chemicals and f so what should I use?

Thanks
