Have you used many Alpha pumps? How do you like them?
Those were my first alphas, there really cool, they are supposed to ramp down to nothing so you don't need a pump control. If they work like the should I think for the price they would be worth it. I haven't had a chance to really look into it but as far as I could tell they didn't shut off all the way.
The electric to you zone circulators is just draped all over. Steel to Copper connections.......is a no-no. Is that an expansion tank laying on the ground with tubing to the drain of the buffer tank? Air separator?
It's not done yet, had 2 days to get it running for the weekend, also Waiting on the right size exp tank, I buttoned up the wiring after, also have a tekmar to install.

What's wrong with copper to steel? Spirotop on top of the boiler buddy.
I was not familiar with the Boiler Buddy.......but apparently a air vent on the top of the buffer tank is all that is needed. They incorporate air elimination into the buffer tank. As far as, copper to steel in a closed loop........it isn't black or white. So it's better to be safe than sorry.

It's mainly about electrolysis, a domestic water line is grounded and oxy rich. A boiler is neither. I helped a boiler maker change out the tubes in a 300 gallon water boiler, if a hole in the plate was to large a copper sleeve was inserted and the tubes were rolled tight against that. That is standard procedure and a state inspected job, after that day I changed my opinions.
I don't see the point to a boiler buddy with a mod/con boiler but that's me. Seems like a really expensive way to decouple primary/secondary loops. Why not just do closely spaced tee's and a spirovent in one of the loops? Cast iron non-condensing non-modulating boiler is a different story, short cycling is much more of a concern ...
