Lochinvar Sync Question

Eric_6Eric_6 Posts: 25Member
Doing some research on some commercial condensing boiler hxers before specing one out.
I was wondering if anyone knew what the hxer surface area is for the SYNC SB1500 or where
to find it? Could not find that piece of info on Lochinvar's website. Comparing it to a Patterson
Kelley Mach C1500H and Raypak's Xtherm H7-1505A.

    Those are three completly different types of boilers. The Sync uses two Genoni S/S heat exchangers. It offers a very good turndown ratio and a very resistant heat exchanger. If properly pumped, it will out last the other two. The Raypak has a standard copper fin primary heat exchanger with a secondary S/S heat exchanger. Under certain design conditions, the copper finned primary can condensate and leak. We have replaced several similar heat exchangers. The KELLY uses an aluminium alloy heat exchanger. Water quality and continuous checking of it,is paramount for any type of longevity. The PH, TDS and conductivity must be checked. We prefer the De Dietrich who have a longer experience in aluminium alloy heat exchangers and offer many more venting possibilities.

    The rating is 130.6 square feet, see attached file. Check out Lochinvar's "Crest" boiler with fire tube design, model FBN1501. I believe fire tube is the best hot water boiler heat exchanger design.
