Good
I know I am late to see seeing this, but thanks! This was a great video and explanation. I have a question regarding zones. I have 3 zones and a thermostat and pump for each. How could I implement this? Would I need three resets, one for each? Or just one for the main living area? Or is it not really meant for my application? Thanks again for the great presentation.
Great video thanks
How about your boiler won't come out of standby?
A customer froze up a cabin where a Noble is installed, and glycol was leaking out of the boiler. It turns out the domestic water in the exchanger froze, deformed it, and it now leaks at both valve connections. I searched for information and here's your video. Just what I needed. Thanks!
Glad we could help!
Anyone seen a video related to changing a flue senson or a FBN2000?? mANY THANKS!!
Some comments: With regards to the Sigma 848 diagram explanation- Pint is not the signal pressure, it's actually the Inlet pressure. From my experience inlet pressure on combination valves does not have to be stable, so long as it is above the minimum pressure (typically 6" WC). I've seen inlet pressure swing from 16" to 6" with out impacting CO2 % at all. Note- with a premix blower (blower located downstream of the venturi) you will not need the rubber signal hose since pressure upstream of the venturi will be equal to atmospheric pressure. Another benefit of leaning out the mixture at low firing rates- in the event of restricted air flow, your furnace will fail lean versus rich causing high CO concentrations.
one of the best explanation that i found thank you so much
Glad it was helpful!
Much appreciated to have access to this type of education. It’s hard to get this stuff all in one place these days on the west coast.
Glad you found it useful. Keep an eye out for the next 3 parts of the series.
thanks for sharing all this, do you have also a book recommendation for the subject ?
This is a really good video; I have watched a bunch of them before making the decision to buy a Tekmar, but found this video after my decision. I'm going ahead with 3x 564, and 5x 561, attached to new IBL SLC, and 3x Life Breath AHU. I hopeful that the installer knows how to set this all up propertly. I think I like the idea of the room response. Overall, I learned a great deal about this system, and feel much more comfortable with my decision. The biggest reason for me was I have a Honeywell IAQ, but I could never find anyone who knew enough about the IAQ, Boiler and AHU setup - so always ginger pointing - hoping the tekmar unifies the support for the complete system. I had two AHU X10 of the 3 motors die and decided to bite the bullet and change out the complete system. Not to mention I have a Munchkin boiler that has been giving me grief for years that I was just fed up with and decided to do one entire new system. Hopefully, it pays off.
Glad the video was so helpful! tekmar is a great product!
Stop clearing your throat
I'll make sure to provide him with some lozenges in the future.
Nicely thought out video. The Noble is a great boiler!
Thank you! It really is!
@@FIA_Incyeah no. As my 83yr old sick ma & my illness (should go to hospital but can't cuz every day it breaks down & EVERYONE has been here for hours over days & now weeks. BRAND NEW. Your tech support is crap. $12K from 2 sick old people whose new heater doesn't work & you've sent NO ONE to help. SHAME ON YOU
Good information but did you record the audio on your toaster?
I think the issue is we had it on the bagel setting.
Has anyone has the issue of flame fail while running? Im going back on a Noble we installed about year ago that is having this issue. In high fire no issue but when it ramps down the flame drops out.
sounds like the venturi needs to be cleaned and a possible combustion adjustment. Contacting your local contractor would be our recordation.
Can you do a demonstration on adjusting gas pressure? Maybe do another with deep cleaning a heat exchanger? Or error codes troubleshooting?
Great suggestion!
Ive been stumbling through the internet to find some good G2 info that was right to the point. Excellent presentation! Answered many of my questions. Although this is a few years old, the data you provided was very clear and precise still. Thank you and two thumbs up sir.
The only people that say "G2" are in a boardroom. The rest of us say INT or intel because other people know what we mean when we convey same concept with fewer or equal syllables.
GOLD!
Great video thanks
Glad you enjoyed it
I'm still confused about how the flow in a secondary circuit can exceed the primary supply. I'm probably confusing volume with flow, but if a primary loop is only supplying 50 GPM of water, how can a secondary pump increase or accelerate that to 100 GPM when the quantity/velocity of water behind it in the supply isn't sufficient to meet the call? Wouldn't that create a massive vacuum behind the tee since their would be a shortage but there's no air to create a void? I mean, I heard your explanation that 50GPM backflows through the common and joins the original 50 GPM that entered the tee initially, I'm just still confused lol.
This video, while old, is a really good explanation. th-cam.com/video/U5nDztGOYDg/w-d-xo.html
Thank you so much ... ex plumber who is retired have a combi installed 4 years ago and need to service. Thank you
Glad this was helpful!
The principles of modern hydronics still date back to this man’s findings. Thank you Gil for your massive contribution to this industry and may you rest in peace
The slide rules he mad by hand are so impressive.
The fact that this video only has 1.7k views and yet countless videos on troubleshooting air and pressure related issues in modern hydronic heating systems have hundreds of thousands, speaks volumes about the state of the residential heating industry. I recently began residential service work, with my prior experience being big commercial hydronic systems and the amount of failed expansion tanks, popped relief valves, leaking auto vents, air bound systems, etc.... that have all just been excepted as facts of life with hydronic heating systems was alarming, The very first thing I noticed was nearly every single one of these systems had circulators on the return pumping into an expansion tank. Anyone that understands any basic hydronic or fluid dynamic principles can understand immediately what causes these issues. The negative pressures on the circulator inlet allow the system fill to continously add makeup water to the system, autovents draw constant air in, expansion tanks get filled with water until the bladders fail, then excess pressure exits the system through the relief valves or autovents. The effect of constantly adding undissolved oxygen into the system compounds all of these issues and creates endless issues and component wear. This video should be part of a required curriculum for any hydronic heating installer or servicemen. We need technicians that understand the theory of how these systems operate, not parts changers and salesmen of misinformation.
Well said. We agree, that's why we have such a focus on education here as FIA
You mean dissolved oxygen
It is a mazing how many refuse to learn the basics.
Just had a Bradford White combi boiler installed in my home. The plumber said I didn't need the outdoor reset even though it came with the unit. Any thoughts? Thanks ahead.
Outdoor reset isn't required, but it increases boiler efficiency and if it can be installed it should.
Any ever have lockout Water press switch erron lochinvar noble combi boiler?
In Manitoba you need to vent 2’ above the ground because of snow
This is amazing. So many commercial installations are incorrectly installed.
It's one of the first things we check for when checking out a problem installation
Very nice demonstration. But... what would be the point of no pressure change if there is no expansion tank in the circuit (theoritically suppose a closed loop circuit which has no heating/cooling function)?
In your theoretically static temperature closed loop example with no expansion tank there wouldn't be one and it would not matter where the pump is located.
You never explained why there is a second pump at the inlet to the boiler on the primary system?
The primary system has a pump to circulate the water around the primary system.
Could you explain further how you got the C_v value of 1.7 in that last example? I'm not quite following.
Thank you so much for this video! Very appreciated and will certainly forward this to my grand children who are in the trades.
Glad you enjoyed it!
This video was amazing! Thank you for sharing this knowledge! My Lochinvar Noble boiler currently has a fail ignition fault. It's been running like a top for three years then just stopped. I confirmed I have spark. I confirmed 26 volt from the board to the gas valve. My boiler goes from pre purge, runs 26 volt to the gas valve, I get ignition (visible) for 0.5 seconds, then boiler goes into post purge and gas valve goes to 0 volt. Repeat 3 more times, error and lockout. I don't have a manometer to check the gas valve unfortunately, but that may be the culprit. Odd to me that I can see it fire through the sight glass and it still shuts off though...any ideas from the peanut gallery???
It’s hard to pinpoint the exact cause for this as there are many things that could be the issue. When was the unit serviced…i.e… burner cleaned, etc..If you do not know I would start there. You can find your local representatives here www.lochinvar.com/locator/
My boiler is working fine but the display screen keep rebooting itself, what’s the solution? Do I have a bad control board? @FIA_inc
Does the unit still operate normally? If it does, I suspect it is not the main control board it would probably be the user interface or the ribbon cable between the user interface and the main control board. I suggest checking all the connections from the display board to the main control board. Power it down then power it back up and see if it goes away after rechecking the connections. Unfortunately there is no way to field test the boards. The main control board is the “brain” and is where the logic takes place, the user interface or display screen is only a window to see into the brain….so to speak. You can find your local representatives and service contractors here:www.lochinvar.com/locator/
It was the interface board. Can the inlet valve assembly be replaced? What’s the part number?
Love how everyone is multi-tasking (on calls, talking to others, even watching TV) when he takes everyone off mute. 😂
I’m seen plastic venturis completely rot out anyway to fix that? Like the plastic crumbles apart
Typically a plastic venturi rotting out or physically breaking down means it is being exposed to exhaust gas recirculation, a laundry dryer vent exhaust or some other chemical that could be drawing into the intake of the boiler.
This guy having domestic disputes during this video? Thanks fukn golden 😂
Bit of free entertainment for you guys!
Great explanation! I'd love to receive a B & G system sizer wheel if still available.
Contact us a training@fiainc.com
Amazing work sir
Thanks a lot
So often overlooked by building engineers. I can't tell you how many cooling towers I have seen sitting on ground level next to the pump expecting the max pump capabilities
And this stuff was figured out years and years ago!
This is amazing explanation! Are there any books or courses you would recommend for going in depth and learning about it more?
What exactly should the heat exchanger tubes look like? I did a dual fan Lochinvar and the tubes to me looked dirty. You didn’t really cover that in the video.
It is a firetube boiler so the interior of the tubes themselves cannot really be seen. You can see the upper chamber where combustion takes place. You can vacuum out the chamber. You can pour a vinegar solution into the “firetubes” but it is not recommended to run anything down into the firetubes like a brush/wire, etc… See the IOM for cleaning procedures. You can find your local representatives and service contractors here:www.lochinvar.com/locator/
Im not getting dhw. At my faucets
I’ve replace the diverter one year and another year I replaced the flow sensor that has a red light.
Flow may not be high enough to trigger DHW, verify DHW flow is at least 0.4 gpm You can find your local representatives and service contractors here: www.lochinvar.com/locator/
Gil Carlson....one of the godfathers of modern hydronics
He really is!
One of the benefits missed is fewer cracked boilers, especially commercial, lower operating temps and less major expansion/contraction make a huge difference in boiler life. I also think that now with higher fuel prices here to stay that ODR is also beneficial to small mass boilers and even a System 2000, I think now they say ODR can be a 10-30% increase in efficiency and that would easily pay for the ODR control in one year or less. Even with a small mass min temp of 160-170 and max of 200-210 there would be huge savings.
Exactly right!
I'm swapping in a new primary loop calculator and that led me to thinking about my boiler short cycling a little much, so here I am looking at what outdoor reset to go with! Thanks!
Glad we could help!
I finally found a presentation that explains what the acronyms are, and what they do. Thank you. I have a stupid question that I couldn't find an answer in spite of searching the web for a week. I wonder if anyone can help. The questions is: why do I want or need a primary/secondary loop? I thought the biggest reasons for P/S were to 1) reduce the temp of the inlet water (shock to the heat exchanger), and also create a path for the boiler circulator. Well, if I ran the system temp as low as possible (based on the fact that I have 40 year old baseboards tha are not something I will replace), why do I need to reduce thermal shock? Ultimately the boiler/system pump should run 4 hours without start/stop. Low outlet temps = low Delta T. So minimal shock to the heat exchanger. Also , If I turn OFF the boiler pump, and have a variable system circulator that runs only if there is demand from the thermostat, why do I NEED a secondary loop? I presently have 8 zones, so balancing the primary/secondary for all system demands would be virtually impossible with a low loss header if you want to minimize return water temperature to condensate during low demand. The system circulator would either be overpower or under powering the boiler circulator based on heat demands (single or multiple zones demanding heat).
We have a presentation on this topic: th-cam.com/video/XdUEtOlz10M/w-d-xo.html
There's a Richardson system in my father's house. It really confused older plumbers when I would ask for help. Now I understand it very well. I have some valves saved, but haven't seen a replacement for the trap-90s.
Excellent presentation
Glad you liked it
For multiple boilers in primary secondary configuration are isolation valves necessary? or would check valve, boiler, circ etc. provide enough pressure drop to prevent flow through inactive boilers?
Check valves if working properly will prevent unwanted flow but Isolation valves are recommended if and when a boiler needs to be isolated to perform any work on it on the water side.
I hope you folks are able to start building some boilers here before too long it is cold in Alaska and there is not one boiler in our state.
