Re: Light weight aircrete ...

Are you trying to reduce the weight of the mix? Or just reduce the conductivity?

They can add an air entrainment at the redimix plant, or you could add it to a home batch

Re: Newbie looking for (re)design guidance and troubleshooting

Oddly enough -- and perhaps counterintuitively -- so long as your velocities aren't outrageous whether the primary flow is straight through the two Ts, or into the legs of both Ts -- or (and this is where it gets weird) one side one way and the other the other won't make much difference. The orientation will change the head loss, but not that much.

That said -- do it neatly. Nothing looks worse than a plumbing job which looks like the installer was high or drunk...

Re: Will 5-Section Boiler Be Too Big for 2300 Sq Ft Home ?rs-home-heating-steam-hot-water-systems/516413

Lots of things:

There are lots of things you should so. Heat loss, measure radiation etc.

We don't discuss price here.

Mty take is that if you get that boiler and burner for $600.00 and it is in good shape and running when it was removed, you'd be stepping over a ten dollar bill to find the dime someone might have dropped. In your lifetime, you will never pay back a new boiler by the few pennies you save over buying the $600.00 Buderus and installing it yourself. Does it come with a Reillo burner? A plus is that you can easily switch that boiler to LP Gas.

If it was me, and I needed a new boiler, and I got a nice boiler like that one, and my wife was warm. and we saved all that money over e new one, she'd be happy. And she might take me out to diner with the savings. A lot more than you have saved with that 368 POJ.

IMO.
