Anyone using the Alpha 26-99 yet?
Hi all, I have a new house and attached garage I bid about a year ago that is finally ready for a boiler now. I laid 9 loops of 1/2" in the basement at 250ft each in a single zone, and 5 loops in the garage split into 2 zones also 250ft long so 14 total. At 30% propylene glycol and .75 GPM per loop, my math says 7 ft of head through the loops and another 10ish through the piping and boiler (UFT-100W piped direct, meeting minimum flow requirements for the boiler with the smallest zone) at 10.5 GPM with all zones calling so I was out of the range of a single 15-58 or Alpha. When I bid it, I was planning on zoning with a pair of 15-58 circs through an SR503 and actuators on the garage manifold to split up the 2 and 3 loop zones. Now that the 26-99 Alpha has come available, I'm considering going that route to simplify things at a pretty modest extra cost. Has anybody played with one yet or have any feedback for me? Possibly a recommendation that I haven't considered? Thanks in advance, you guys are great
