Energy Kinetics Resolute
Model Number: RES
Entry-level Energy Kinetics with thermal purge technology.
Technical Specifications
Prices depend on sizing, venting and piping in your home, so we quote every installation.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

Expert Review: Energy Kinetics Resolute
The Energy Kinetics Resolute is the high-capacity option for larger Long Island homes. The patented thermal purge technology scales up for demanding applications, providing fuel savings in estate homes and multi-zone colonials. Output up to 200,000+ BTU handles larger heating loads efficiently.
New Jersey manufacturing since 1979 ensures quality and Northeast expertise. The Resolute brings System 2000 efficiency to homes exceeding 3,500 square feet.
For larger homes with oil heating, the Resolute often matches or exceeds the efficiency of smaller condensing gas units. Flexible fuel compatibility suits various applications.
The 15-year heat exchanger warranty provides excellent long-term coverage.
Our recommendation: The Resolute is ideal for larger homes where the premium investment is justified by substantial fuel savings over 25+ year lifespan. Best for efficiency-focused homeowners with larger heating loads.

Sizing & Installation Notes
Hot water boilers like the Resolute are sized from a room-by-room heat-loss calculation. We never match the old boiler's size — oversized units short-cycle, waste fuel and wear out years early.
Every Energy Kinetics installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, and gas or oil supply sizing. Learn more about our boiler installation process, or see current rebate and incentive programs that may apply.
