Check out the before-and-after transformation of this completed heating and domestic hot water system upgrade.
We replaced twelve existing HydroTherm boilers with:
• (4) Lochinvar FTX1000 98% efficient fire-tube boilers
• (4) Bell & Gossett ecocirc XL 20-140 circulator pumps
• (2) Lochinvar STU150 125-gallon reverse-indirect water heaters
• (2) Lochinvar RJA200 ASME storage tanks
• (2) Bell & Gossett ecocirc XL 65-130N stainless-steel pumps
• (1) Bell & Gossett PTA-42V ASME potable expansion tank
The project also included new boiler pumps, ECM boiler kits, condensate neutralizers, a magnetic dirt separator, an air separator, air vents and a B600 bladder tank.
Our team completed the piping, insulation, labeling, controls, electrical work, gas piping and sidewall venting. Temporary boiler service kept the building’s heating and domestic hot water operational throughout the project.
