[@frenchonion3359]

Thanks steve i’m a 7 month apprentice at a small company and this is really helping me learn as much as I can as quickly as possible!!

[@pauljamilkowski3672]

Same!

[@ramonpad]

Thanks for sharing. I want to wish you well and let you know that I am learning a lot. I live in CA where we don't face the same winters you do and it helps me to understand a lot.

[@Davidjames70]

Huge help Steve, Im going through an HVAC course and your videos are filling in alot of blanks for me.

[@shawnkumar5650]

Dillip NYC like u video very educational surprising a lot of junior and senior when rookie is figuring it out thank

[@Brad1237202]

Thanks for explaining the difference between the boiler and domestic expansion tanks.

[@stevenlavimoniere]

thanks for watching

[@deltafour1212]

Best damn videos on hydronic heating out there

[@stevenlavimoniere]

deltafour1212 thanks for the comment

[@hvacir9176]

this series is amazing thank you

[@amilnasser1426]

Great information. Thank you, God bless you.

[@phillipjohn08]

I live in Houston TX and I'm having a problem passing the NATE senior efficient exam because of lack of hydronic experience. so I hope these videos can help me.

[@raymonddebrooke463]

Nice video Steven, step by step we will get this Hydronic thing down. Keep up the good work. Ray

[@stevenlavimoniere]

yes step by step gets the job done this way i can go over stuff that you can run into at the end of the series i will go over the whole system and possablle problem and fixed

[@dcrickerson9775]

Thanks Steve, looking forward to more.

[@stevenlavimoniere]

[@nicholasceea4109]

Another thumbs up winner!

[@stevenlavimoniere]

Nicholas CeeA thanks nicholas

[@drodriguez394]

Another trick would be press on the shredder valve. If it sprays water the bladder is leaking by

[@mtngoat58]

cool ---good info ----going to try and build a wood fired boiler for my shop

[@stevenlavimoniere]

***** make a heat exchanger in stove .with a relief valve for temp and pressure

[@weedandwine]

Did you wind up building that wood fired system? How did it go?

[@mtngoat58]

still working on it when I get time don't want to rush it and blow something up -----just ordered a expansion tank so I got it when I am ready

[@RappyMcRapperson]

great stuff! Thanks for the video

[@RobHVAC]

Nice video Steve. I just had to drain a tank today.

[@stevenlavimoniere]

thanks for watching rob

[@eggyhead2172]

Great videos, very helpful AAA+++ Thank You

[@palmer0332]

Hey Steve. This is off the subject but do you guys get better ratings if the commercial at the beginning of your videos runs completely thru or if I hit Skip commercial does that hurt you in anyway? I always wondered and I want to do right by you guys taking time out to do these videos and all. Thanks.

[@visalyok4793]

very informative and thanks for sharing

[@TheBergy32]

Very informative, part 1 too. Thanks for sharing.

[@stevenlavimoniere]

more to come

[@rcj509]

Great Video Steve!

[@stevenlavimoniere]

thanks rob

[@fleetwin1]

OK, I understand the theory, but am confused when you speak of draining these expansion tanks....I thought you mentioned that if there is any water inside, the thing is junk...I have two of these things for the two systems in my home, both mounted up in the beams in the basement. One of these things is mounted sideways, which seems kinda strange...I guess I have to figure out what type expansion tanks I have....Neither boiler is popping the relief valves, so I guess all is OK, unless I have a lot of air in the systems....

[@salmonhunter7414]

I know it is an old video but still is very good thanks

[@stevenlavimoniere]

+James Splint thanks for the comment

[@hangngoaigiare]

Thank you very much Steven. Great videos I really like it. Would you do on site training with a fee?

[@mathewbetcher9663]

+1 good info for the newbs, I can tell craftsmanship is better in your state than here on Long Island! I see 15's all the time when it should have a 30. What's your thoughts on pre charging domestic tanks? I never used to do it until I saw this video. Adjusting the Pre-Charge of a Thermal Expansion Tank

[@stevenlavimoniere]

good points m bet

[@septicman361]

Nice video steve

[@stevenlavimoniere]

thanks septicman

[@salmonhunter7414]

how big of an expansion would you need for an open system with 2000 thousand gallons water with water temps around 190degrees? is there a formal ?

[@rem24319821]

Awesome I be learnin alot lol

[@stevenlavimoniere]

more to come

[@jbpost52]

Steve, how will you know if the owner played with the schrader valve on the expansion tank, and let air out. I have such a friend who has an undersized hydronic piping system, poor insulation in home so house can never get up to temperature in this extreme frigid weather we are having. When I stopped by he mentioned that their is air in the expansion tank, which leads me to believe he let the air out or some of it. Can a bike pump be used to put air bank into the tank once air was mistakenly removed?

[@stevenlavimoniere]

pressure should be 11 or 12 psi in tank with no boiler pressure on tank . yes you can use a bike pump .

[@TandNServices]

Can you use a water heater expansion tank on a boiler

[@stevenlavimoniere]

the tap is bigger its 3/4 not 1/2 but i am sure you can its just never done there a lot more money for a domestic ex tank

[@raganoheatingacinc.4643]

when a diaphram tank looses it charge , do you replace or use a bicycle pump to #12

[@stevenlavimoniere]

depends if it has water in it when i remove it then its junk and i replace it

[@kennyplay5982]

Hello. Question. I have a 1 zone system with old style expansion tank on ceiling. @ 8:00 , how much water should be in the tank? How much should be drained out? All the water? It's Hard to tell since I can't "see into the tank". Thank you!

[@bernardaflores1720]

Your tank should be totally empty and just knock on the tank it shound different.

[@rightchoicehvac3620]

So more water pressure on the water heater than the boiler?

[@stevenlavimoniere]

yes 12 to 15 lbs is the norm up to 20 lbs is ok the relief is set at 30 lbs

[@landongall2080]

Very knowledgeable and great videos, but for the love of God clean your fricken yard man haha

[@bhop2920]

Steve do you know how to size the expansion tanks?

[@stevenlavimoniere]

i can tell by the piping if its a large volume system i would go with a # 60 tank .there is a formuilar but i never needed it for what i do

[@slimlucas7486]

its 15 and 30 expansion tank not 30 and 60 for residential no offense jjust dont want pple to get confused 🤓

[@phillipjohn08]

I live in Houston TX and I'm having a problem passing the NATE senior efficient exam because of lack of hydronic experience. so I hope these videos can help me.

[@stevenlavimoniere]

phillip john i work on mostly hydronic heating .. up my way

[@phillipjohn08]

The hydronic part of the test is giving me the most problem mostly the zone questions.

[@winkhvac62]

Nice video steven

[@stevenlavimoniere]

thanks wink
