New Boiler and Piping
Comments

it sounds like you need to learn how to install this yourself.
things that aren't typical residential are say a school building where there are say 2000' of main going down several wings of the building or a 6 story nyc or chicago apartment building where there are 4 rooms on each floor all stacked on top of each other so each riser through the building has like 1/4 of the load on it.
also, i stopped reading where the second paragraph should have ended.

the other thing to look at to see if the boiler is big enough for some hot water loops is to look at the heat loss of the house. if the boiler is still bigger than the heat loss of the house then you absolutely don't need to add extra for hot water loops. if yo start putting in a lot of hot water loops to heat parts of the house that aren't heated by steam then it could make sense to have a separate boiler for that if that load starts to get to be say half the output of the boiler.

also if you click on that little wavy thing by the top of your original post it will notify you when someone replies.

I disagree , They don't do their best to answer the questions they go above and beyond. The good this site has done through the years for so many can never be measured. Thank you Again for all your help.

Thank you so much for that tip about the wavy thing. This is the first time that I've ever posted anything anywhere. I'm really not too savvy when it comes to this sort of thing. That's probably why I made the dumb mistake of not hitting post comment After I finished my draft. In the post that you mentioned ,farther down I explained how I kept going and checking for 2 days to see if there were any responses . When I mention that I thought I was dumped that was not in any way A reflection on you guys. That was meant to be a reflection on me the old fool who keeps going back for days looking for a response from a post he never posted. You guys have been absolutely amazing believe me I can never thank you Guys enough. And if I'm allowed to continue posting until I get this boiler done I promise you no more jokes. Which is gonna be really hard I've always been like that It's the only thing I got left.๐ฅฒ

You have 746sqft with possibilities of more and the WM EG-75 is 733sqft rating I personally would go with that. If a steam expert has the luxury of walking through your house and doing an assessment of what you have (insulated and uninsulated pipes, whether risers to 2nd and 3rd floors are in interior or exterior walls and insulatedโฆ) you may very well be able to go smaller but you should certainly be in good shape with the EG-75 choice.
What does the system currently have for main venting?

Thank you so much I really appreciate you responding to my post. Sorry for the delay in getting back to you. My situation is a little different. During COVID my wife brought 2 family members from Chicago and took care of them here in our home until they passed. I still have a family member who has had 2 operations and an upcoming one that's the most serious. With a compromised immune system and severe anxiety. Because of this we've had no one in the house Since COVID .I've been put in the position where I have to do anything that doesn't involve the basement. So I Measured and calculated all the radiators with the styles measurements and made Printed copies to handout . I went through the house and I checked all the piping that you had mentioned. Most of them are on outside walls but luckily inside the house Running through the rooms Not in the walls. Only The portion between the ceiling and the floor above. There are no Main vents in the basement at all. I can only find 2 places that they had previously been. So that also will have to be addressed. I also have the 15 feet of copper fin Hot water loop That was installed before I purchased the home. It too was done totally wrong. Also printed out copies of how it should be done I believe from one of Dan's books. From what I was told I don't have to add that in to the total of the EDR. Thank you again

II fell as I need a little help I have A Boiler guy here who says the wheil McLean EG75 only has one Tapping going to the header I thought it had 2 Could you Let me know where the confusion's coming in.
0 -
it has 2 but you might need to remove a plug and cut a hole for the second one in the jacket.
1 -
Thank you so much for the quick response I really appreciate it. Is there A document somewhere where I can prove this or some pictures. Cause he's insisting that it's only one And even if He doesn't do the job at least I'll have my poof for the next one. Anything you can do I'd appreciate it.

table 7 on page 17 shows either 2 2" risers or 1 3" riser. also have them lift up the jacket and look.
also on page 35.

They show you have the ability to do a second supply as an option, but to my knowledge ( I have an EG boiler) they all have the second tapping available if you choose to use it. As stated above I think it comes with a plug installed on many of them, but it can be used on any if one chooses. It's a bit worrisome if a professional has installed these boilers and hasn't noticed an obvious plugged hole on top of the boiler block. That strikes me as odd.

Thank you so much for the quick reply I really appreciate it. You guys are awesome!!

Weil Mclain boiler does not come with any plugs

They want a 3" header on that boiler.
So (1) 3" riser will save you 1 3" tee, a 2" union and at least 2 2" 90s and some pipe and or nipples
It will cost you 1 3" 90 and some pipe, no union needed.
Keeping it 3" with 1 tapping is better IMHO and any price difference is negligeable. The area of a 3" pipe is over 7 sq inches. (2) 2" is about 6.2 so it will work better anyhow. Less labor and less material.

Thank you. So that means it's Up to the discretion of the installer not that it has to be either or. Now since you had suggested I believe it was either too takeoffs from the header or 3. Having only one riser will that cause any issues In regards to how that's Piped. I can tell you that the big issue I'm having is they want to Install the near boiler piping correct But when it comes to 2 or 3 takeoffs to the mains they wanna connect it the way it was already Connected in the center with one takeoff. I know that's not good can you give me an idea just how bad. I did reach out to Randy Houston plumbing unfortunately I'm out of his range. You did say he could make a trip for a consultation and I'm sure it would be worth every penny. But if I can't get anybody here to pipe it with the extra takeoffs it won't do me much good. Here's the picture against so you can see. Thanks again guys .

Do not let them put the tee between the boiler risers (if you use 2 risers). (I am referring to the uninsulated tee between the boiler tappings)
As far as the overhead insulated piping it looks like you have 3 supply pipes. Yes they should come down to the new boiler header individually.
But it is an expensive change. But you should have it done. You want it to look like the picture @EdTheHeaterMan posted on 10/20.
Will it work if you tie it in to the old pipe? Maybe but if it doesn't then it more money to change it.
1 -
Thank you Ed. The nearer boiler piping will be done right. That I can't mess with. I'll keep pushing to get the rest of it too.๐ค

so the other end section isn't drilled and tapped for the riser even though it shows it in the manual as an alternate?
1 -
Usually if you buy a boiler that is "Knocked down" and you have to assemble the sections they will have no plugs. If you buy a boiler with the sections assembled but with the jacket burner and controls off it would have no plugs. A Package boiler with everything mounted would have some unused tapings plugged. But I would think if the riser use is optional they would not be plugged.
Maybe @STEAM DOCTOR means Weil McLain ships the boiler without any plugs in it. IDK

In this case the steam velocity (in the riser) with the single 3" riser is better (lower) than with the two 2" risers so I would let them just do it with the single 3". You could go two 2 1/2" risers but that would be overkill in my opinion.

Thank you For your response. So it looks like you're in agreement with Ed Okay. Now it looks like I may be going with the peerless 63 06 A little more EDR And 4 more gallons of water Then the EG75. I assume the piping Recommendation won't change. Now the peerless comes with A Hydro level CG450. Now it's saying that I should get the hydro level VXT water feeder with feed delay. But I'm hearing different things what do you guys think would be the best way to go.
0 -
the 63-05 or 63x06 would be the right peerless for your system.

Thank you for Your quick reply. I ordered my new 63 06 today ๐๐ฅณ. I wanna thank everyone for all their great help and patience that they showed me.๐๐๐
