Paxo/EKO HX tube Dia?

I am out of town with the military for a few more weeks, but the wife is doing a wonderful job running the PAXO 25, but she seems to be noticing that its "not putting out the heat like it used to" when I first left about a month ago. The turbulators, dont seem to scrape the walls like I hear people say their EKOs do, or it might be the fact that its a Paxo 25, and it never did since it was new. So non the less, I think its time to pop the rear cover and run a brush down the tubes mid season.

Does anyone know the Diameter of the HX tubes, so I can order some brushes through grainger so I can clean it right when I get home. I am guessing its somewhere in the 1 1/2- 2 1/2 range.

Maybe I can rephrase this, if anyone else has bought brushes for their boiler, just tell me what boiler you have and what size you bought. They only come in 1/2" increments, so there are only a few options anyways.

Don't Know if there all the same but I'm guessing mine are 2" ID forgot to measure when apart. 2 1/2 seems to big
and 1 1/2 definitly to small.

That sounds like a pretty good guess, I am away on a trip with the military right now or I would reach in the lower chamber and get a measurement from below if I was home, I just wanted to get a brush ordered from Grainger so it would be waiting for me when I get home next weekend, if someone has done it before.

Thanks

The EKO40 has 8-2" tubes or the closest thing metric offers...

Not wanting to hijack the thread but, how long would those pipes be ?

By looking off the paxo users manual schematic on AHONA's website, they extend from just below the flue collar to about 3-4 inches from the bottom chamber floor, so in the EKO/Paxo 40 they are about 40-42" if you are looking to extend outside the unit on a drill, its in the 48-52" range. The EKO/Paxo 25 is more about 6" shorter.
