primary/secondary boilers- jim f.

just fooling around with sizing my pictures. here are 2 burnahm 8 section boilers piped primary/secondary. this was my first prim/sec job. a lot of research went into this one. the primary loop is about 250' of 2" black with 3 seperate mechanical rooms srategicaly placed around the house. there are 9 hydro-air systems,3 garage unit heaters and an indirect tr-100 phase 3. the sub picture is the primary pump on this system. i do need to learn more on some modern operating controls. the main pump is operating on a outdoor t-stat set at 62*. the 2 taco 007's on boilers are operating 24/7. being i did not price this job, no for thought was put into controls on the original bid(against my better judgement). any way it is what it is. this system is a glycol system at a 60/40 mix. i can't remember off the top of my head but i think we put in about 75-80 gallons of glycol. this job was located in greewich, ct. and the house is approx. 13,000 sg ft. going for 4.5 million dollars.
