The System 2000 Frontier is Energy Kinetics' integrated heat-and-hot-water system, published on the official site as 'System 2000 Frontier Boilers' with the claim that it combines heat and hot water in one system and incorporates the company's Energy Manager control. The product page describes a low-mass spiral 'energy converter' with a 10-foot wide open flue passage, a high-temperature ceramic combustion chamber, a 2-inch insulation wrap, a swing-down door for service, an advanced plate heat exchanger, air elimination and a high-efficiency ECM circulator, with chimney venting standard and a power-vent option for installations without a chimney. The page and brand literature position the line for residential heating plus domestic hot water from a storage tank, and the brand's overview page groups System 2000, Resolute and Accel CS as the company's heat-and-hot-water systems.
The EK1/EK2 gas data sheet prints the model-level ratings documented here. EK1 Frontier: 80,000 BTU/hr input with 69,000 BTU/hr gross output at 86% AFUE (natural gas) or 70,000/88% (propane); 100,000 with 85,000/85% or 88,000/88%; 120,000 with 101,000/84% or 105,000/87%; 150,000 with 125,000/83% or 129,000/86%. EK2 Frontier: 175,000 with 149,000/85% or 153,000/87%; 200,000 with 168,000/84% or 172,000/87%; 225,000 with 187,000/83% or 192,000/85%; 250,000 with 204,000/82% or 209,000/84%. The data sheet lists water content of 2.5 gallons (EK1) and 4 gallons (EK2), energy-converter weights of 270 lb (EK1) and 350 lb (EK2), 3/16-inch pressure-vessel steel throughout, ASME code construction and National Board registration, a 300°F net stack temperature, and wet-base design. A commercial EK3 sibling covers 300,000–399,000 BTU/hr gas input (up to 87% combustion efficiency) and is linked from the same literature page but not documented at model level here.
Boilers.ca documents the eight EK1/EK2 gas rating rows at model level from the data sheet and links the published warranty and System 2000 brochure. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'.
