Lochinvar · Series
The Epic is Lochinvar's residential fire-tube condensing line in three forms — the EPB wall-mounted heating boiler (80-199 MBH), the EPC wall-mounted combi (110-199 MBH) and the EFC floor-mounted combi (110-199 MBH) — all rated 95% AFUE with 10:1 turndown and the SMART CONTROL.
Series facts
95.0% AFUE is printed for every EPB, EPC and EFC size in the submittal rating tables.
The Epic fire-tube line covers three mounting and application choices on one condensing platform: the EPB wall-hung heating-only boiler in 80, 110, 150 and 199 MBH; the EPC wall-hung combi in 110, 150 and 199 MBH plus a dedicated 99.9 MBH EPC110N-CAN model for Canada; and the EFC floor-standing combi in 110, 150 and 199 MBH. Every size in the three submittal rating tables is rated 95.0% AFUE with a 10:1 turndown, ASME H stamp and ENERGY STAR certification, and the combis produce domestic hot water on demand — 2.6 gpm at a 77°F rise on the 110, 3.6 gpm on the 150 and 4.8 gpm on the 199 per the EPC submittal.
The product pages describe an ASME stainless steel heat exchanger, the SMART CONTROL operating control, a universal vent adapter that accepts PVC, polypropylene or stainless steel, 2" venting to 100 feet on the 80 and 3" on the larger sizes, and a 10-year limited heat exchanger warranty with 5-year parts coverage. The combi pages also describe the control's patent-pending logic that eliminates the cold-water "sandwich" between DHW draws, and an air-handler interlock for hydro-air installations. The EPB submittal prints gas connections of 1/2" and water connections of 1", with shipping weights from 120 lb (EPB080N) to 140 lb (EPB199N); the EFC floor combis add a boiler water connection of 1" and 3/4" DHW connection with weights from 184 to 215 lb.
Highlights
The EPIC product pages print a 10-year limited heat exchanger warranty and a 5-year limited parts warranty.
