Great content with lofts of useful knowledge. Too many times I hear complaint on water heaters not keeping up with demand. I am not sure if I missed it yet one way to help an undersized boiler is making it a priority, instead of leaving as a separate zone.
Was just going to comment this, I'm in NJ and most of the time its on priority but the installer put a zone valve in with a low cv rating so the thing never keeps up and the boiler short cycles then you obviously have problems trying to heat the building because the tanks never satisfied...
have only ran out of hot water twice in 11 years with a buderus s120 (32gals) piped with 3/4" to/from. i'll redo the math from this lesson, but i might need 1" to/from. Quite informative, thank you
@@TacoHVACtvactually, yes. Im looking to do manifold home-run setup for finned baseboard heaters in a zone, that way all heaters get same inlet temp as opposed to diminished inlet temps in the present series configuration. Is there a guide for calculating sizing for supply/return for the manifold, and the individual pipes for each home-run? thank you.
@timp.9582 To take this in a different direction than the webinar presented here you may want to take a look at the Taco After Dark series that will walk you though all of the steps needed. For your particular project, watch episodes 1-3. Episode 1 discusses heat loss and how to calculate it, Episode 2 reviews heat emitters and how to size them and then episode 3 with review how to size the pipe based upon the calculated flow rate needed that you found in 1 and 2.

@@TacoHVACtvThank you for your reply. The heat loss is informative, did it years ago, but it doesnt hurt to have a re-review of it. Ya'll have done a fantastic job with all of these workshops/webinars. BTW, i see Dave Holdorff is one of the trainers. Dave was 3yrs ahead of me at Ft Schuyler.
Hello there, I really enjoyed and appreciate the data in this video. I have a gas boiler, and an indirect tank. It has its own thermostat on it. I had a second tank installed. I learned the hard way that it had to have its own thermostat to talk to the boiler. Done. Now the big problem is my renter gets 1/3 of a tub of hot water for her bath. The companies here have not been able to figure out why. I am really curious how you would install a system like this. Absolutely nothing available online. It would be great. I can send digital photos, drawings, whatever you like. Let me know please, and thanks again.
Indirect tanks for hot water generation connected to a boiler have specifications based upon the amount of hot water it can generate. The biggest factor is the size of the boiler. Most residential boilers are just big enough to handle one indirect tank for a family. Adding two; the size of the boiler must be calculated properly in order to handle the load in order to create enough capacity. Let us know where you are from and maybe we can connect you with a contractor we know in your area that can help.

@@timp.9582 Hey Tim, this is a much different way of learning about heat transfer than in the days in the Bronx, deck or engine?
