Laars Mighty Therm2 MT2H 2000 in practice
The MT2H 2000 is the 2,000,000 BTU/hr hydronic size of Laars' Mighty Therm2 replacement-market line, documented in the Document 1560 submittal and the Document 1211M I&O. The submittal sizing table lists 2,000,000 BTU/hr input, 1,704,000 BTU/hr output, 85.1% thermal efficiency, a 2" gas connection, 2-1/2" water connections and a 1200 lb shipping weight.
The Mighty Therm2 is designed for the replacement market with simple, straightforward controls and two-stage firing up to 4:1, a modular construction that separates burner trays, gas train and blower assembly, and fan-assisted Category I venting (Category III with a listed vent system). Model MT2H is the hydronic boiler and MT2V is the volume water heater, with heat-exchanger configuration letters printed in the I&O.
