Purchase made - Froling S3 with dual 240 gal Storage

Oh......and the boiler shows up tomorrow, its starting to get real now.

I got a cheap Harbor Freight pallet jack to move it around in the basement when it was still on the pallet. I have other uses for it though, moving tons of pellets around.

Short sections of small pipe work great for moving a boiler around on a hard floor.

I actually purchased a garden cart rated for 1100 pounds. I will lower it into my outside stairwell with my moni excavator. Place it on the cart and then pull through my recroom, home theater room to get to boiler room. I actually hav to take down one wall to get this in the room lol. What a guy wouldn't do to get gasification lol.

Some teaser pics. As you can see, lucky it made it in one piece, pallet was busted on one side.

The brains, 3-way diverter valve, low water cutt-off sensor, and cold water protection valve.

Ok makes sense. My highest point will be the supply and return manifolds so thats where i currently have air vents on the old system. Seems to work, i rarely get air out in the zones. Having the vents on these, on both tanks and DHW heater, along with the air separators off each boiler supply piping should take care of the air im hoping. I will update the dwg in a few days to get everyone's thoughts. Appreciate all the feedback here.....thanks

True, where would be a good place to plum it in.

That is a good question, no perfect answer though.. Read article make a decision.

Sorry forgot to attach the article. The boiler looks like quite nice. I would put the dirt mag to the right side of your boiler thermoblock unit

Caleffi Discal.

You can plumb your expansion tank at the bottom of discal but use a tee and i see this is your fill point?

Yes, I have a drain for the air sep there, another tee for the make up water, and also a connection to the left for the expansion tank. Is there anything wrong with that arrangement?

I forgot about the idronics collection. It's a good read if you haven't. Here is a link showing what I was describing before. Again so long as your circulator isn't cavitating it shouldn't be an issue but this explains the reason for the ideal location.

[hyfire]

So it looks like the ideal location is at the bouler return connection nipple with a tee and a valve for tank service.

If it were me I'd do the expansion tanks in 3/4" make up water in 1/2" and the drain could be either. Mine is 3/4"

I would do the same way he also has to use a listed backflow preventer valve and pressure reducing regulator on the fill point. Also i would incoporate a drain spigot at the expansion tank, dirt seems to collect at the bottom of the tank, he needs to put a tee there and as well and once in a while flush it out.

He should already have a back flow preventer and pressure reducer in the line feeding the boiler. Both systems are tied together anyway so I don't see the need for a second set.

1/2" is way adequate for expansion tie in.

Correct.....this already exists but I will be relocating. Right now its just at oil boiler inlet.

I was Reading this article on temperature vs flow rate have a look at what they show vs temperature for DHW not sure if it applies here. If we look at the flow rate then 1" would not provide 2 fps above 160F. But I guess it be OK with 6 gpm and 40 degree Delta T. that would be about 100k btu load

You're comparing DHW to a sealed pressurized boiler system? Does not seem applicable to me?

Its more of a concern in boiler systems since the water circulates more hours than a dhw system, so it applies the same. He will be Ok with 1" if he can get a highdelta t and lower gpmi,ts just something to think about at the high temps long term and pipe lifespan.

Thanks Hyfire.

Good info but I will have to take my chances now, all 1" components purchased. Also, the current system has plenty of 1" copper pipe and the circulator between the two existing boilers have been running straight time during the cold season for 18 years and pipe is still holding. And im pretty sure the existing pipe is not type K.

I tend to taker some of the literature with a grain of salt but I still appreciate all the info, and i read every article I can, knowledge is power!!, especially when your learning. Thanks

 

[Newfiestang]

Started the 3D piping, work in progress but im hoping that I can pretty much have every component counted for by the time the summer roles around and im ready to install. I dont live close to the major supply shops in Newfoundland so having a 3D drawing of the actual boiler room should help alot with trips to the supply store. From this drawing I will create a complete BOL (Bill of Materials)

The detail of some of the 3D CAD models is absolutely crazy these days. Im an old school ACAD user and just learning this 3D stuff as I go and Im in aww of where its gone over the years. Below is a Caleffi Quicksetter adjustable flowmeter.
