Energy Kinetics Accel CS EK1C-90 in practice
The Accel CS EK1C-90 is a condensing gas boiler rated at 90 MBH input. Its row in the Accel CS residential brochure prints 84 MBH capacity at 96.6% AFUE and a hot-water first-hour rating of 155 gal/hr; the brochure footnote states the DHW rating is based on a first-hour draw with a 67°F rise and a 3 GPM draw on a 40-gallon tank, with draws over 195 gallons calculated on continuous draw at maximum flow.
The Accel CS vessel contains over 70 pounds of American-made 316L stainless steel with 37 stainless-steel super turbulators, wide-open water and flue passages, a fold-down service door and an AL294C stainless-steel condensate collector and flue. The Condensing Energy Manager control runs Hybrid Energy Recovery and SmartBoost with low-temperature reset, and the brochure lists multiple venting options (sidewall direct vent, through-the-roof and chimney), natural gas or propane with easy conversion, and a residential lifetime limited warranty with lifetime transfer to a new owner.
Boilers.ca documents this printed model at model level from the brochure and links the published Accel warranty. Gas, venting and electrical work belongs with a licensed contractor. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'.
Best suited to
- 90 MBH residential heating loads
- Households wanting a 155 gal/hr first-hour hot-water rating
- Retrofits with a sidewall, roof or chimney vent route
