1-my heat exchanger in the plenum now has 3/4" fittings should I buy a new one that has 1"?? or run as far as I can with 1" then drop to the 3/4"? :o
This is why I replied that if the fittings were changed from 3/4" to 1" it would flow better,but only going by my personal experience with the 3 exchangers I bought without the fittings & I had to choose the size fitting to solder on. Someday I may get my fingers to type socially acceptable wording so as not to anger the masses. My exchangers had 1" tubes to solder fittings to,so I soldered 1" fittings on & connected 1" pex to them.All of the exchangers work fantastically & the only way they could work better is to hook to 1" ID pipe instead of the pex with its 3/4" ID. Is this now STING approved or does it DEPEND ? :) :)

So much of this depends on fluid dynamics(behavior of fluids under pressure)
(air is considered a fluid in the scheme of things).

The fan used to push the surrounding air across the radiator fins is also a
huge factor. The fans ability to push the air through the radiator(heating appliance)
is also part of the puzzle as cold air is denser than warm air which provides a greater
ability to transfer heat into the air passing over the radiator for heat transfer or cooling
The Lake Source Cooling System used by Cornell University, The University of Hawaii
using deep cold ocean water and The City of Toronto, Ontario, Canada using deep
Lake Ontario waters are premier examples.

The other issue part of the puzzle is in low pressure fluids, the internal surface area
of the piping and heat exchanger plus the surface area of the return piping
which is creating the resistance to flow.

The heat exchanger is going to radiate as much heat as possible within the
time X amount of fluid passes it through it with the gallons per minute through the
internal surface area of the piping and the heat transfer ability of the water to
air heat exchanger being the BTU loss per foot of radiation.

I really don't understand why this keeps going. The OP said he had no problem with the coil operation!

Let's remember, the only piece of this puzzle that is being reworked/changing is the pipe. (flow)
Same pump, same water temp, same fan speed.

His question is about how will some possible piping changes (will it change flow) to now effect the performance from that of his prior piping.
I believe his desire is to match what performance he had previously. :idea:

The OP asked if he should change the exchanger to match the 1" pipe . Others posted that no change is needed if exchanger had satisfactory output as is. I simply posted that by changing to 1" fittings on the inlet & outlet of the exchanger he would have 1" flow the whole way. I was assuming that based on my exchangers all being 1" inlet & outlet,his may be smaller . I never intended to start a war from this totally out of proportioned mis-understanding of my post on something that I thought could help based on what I have personally experienced with the exchangers I have worked with. I am now :( :? :sick:

Now I'm more confused than I was before :shock: :shock: :D The exchanger is 3/4" so... I guess I will leave it and neck down after coming out of the boiler.. :D :)

Anyone have any suggestions on getting this monster in the cellar??

I'm sure an expert at this type of job will be the next to post so you shouldn't have long to wait for the proper way & safe way to get it done.

Unlike what the expert says, it's been my experience that K-8"s are pretty heavy and don't slide down planks. Even at a steep angle. A couple pieces of 1 1/4" rigid pipe will let you "slip" that baby down any plank with ease. I would suggest using good 2 x 12's as the boiler will shift to one side or the other once in a while. You might have problems anyway with the height of the boiler hitting the header coming down the stairs. Be sure to measure for clearance after the planks are set. Good luck. If you need a hand, I have time to help.

It has also been my experience that boilers don't slide on planks easily...but the advice to stay away from the "landing zone" is spot on. Safety should be the primary concern.

Wow Scott thats quite an offer :shock: Do you know how far away from where you live to where I do???? :shock: :shock: It's laying down on a pallet now.Think it would be ok to leave it on that and take it down the pipe that way???

Remember to double check the 'head room' for the boiler to get into the basement. Make a mock-up the size of the boiler and check it out. Getting it stuck in an awkward place and angle is no fun. PPPPPPP. Bribe Scott and save yourself some time and enjoy a pleasant experience.

You could also run 2 or 3 pipes lengthwise down the steps & slide it down on them OR if you can remove the steps without too much trouble you could lower it strait down onto a skid with pallet jack,floor jacks or platform with rollers. Do it the safest way regardless which way you choose to do it. Keep everyone out from the below zone.....weight + gravity can make squish.

CNY,

If it can wait till after the holidays and Scott is willing , he could pick me up on the way by and Ill help out. Even though it's not a "blue unit". Im up in Dryden so no biggie for me... Put up some pics of the basement entry and the approach and lets round table the thing!
