The brochure prints the same 40,000 BTU/hr minimum fire on both, so below the 160C's ceiling they modulate identically; the 199C raises the maximum to 199,000 BTU/hr.
Hot-water delivery rises from 3.85 to 4.8 GPM at a 77°F rise and the first-hour rating from 250 to 300 GPH, with the performance chart printed for the 199 model at 199,000 BTUs at a 77°F rise.
Both are 55-gallon, 310 lb units with a 64.5" x 23" cabinet, 3" vent, 1.25" NPT supply/return, 3/4" gas and the 12-year limited warranty.
The HTP PHR-160-55C is the 160 MBH class model of the retired Versa-Flame combined appliance line: 40,000 to 160,000 BTU/hr input, 55-gallon 304L stainless steel buffer tank, 3.85 GPM at a 77 °F rise and a 310 lb package, recorded from the official HTP-Versa-Flame brochure table.
The HTP PHR-199-55C is the 199 MBH class model of the retired Versa-Flame combined appliance line: 40,000 to 199,000 BTU/hr input, 55-gallon 304L stainless steel buffer tank, 4.8 GPM at a 77 °F rise and a 310 lb package, recorded from the official HTP-Versa-Flame brochure table.
The firing ceiling (160,000 vs 199,000 BTU/hr) and the resulting hot-water delivery (3.85 vs 4.8 GPM at a 77°F rise; 250 vs 300 GPH first-hour).
Yes — the 160 and 199 print 3" venting; only the 130 uses 2".
The PHR-199-55C at 40,000-199,000 BTU/hr.
A consultation includes a heat-loss review so the size is right the first time.
