System 2000 by Energy Kinetics is not a conventional boiler. It is an integrated heating and hot water system with a patented Hybrid Energy Recovery cycle that delivers real-world savings of up to 40% beyond what the AFUE rating alone suggests. We install and service the full Energy Kinetics lineup across Nassau and Suffolk County, including the Frontier, Accel CS, Resolute, and Ascent Combi.
System 2000 is not just another boiler. Manufactured by Energy Kinetics in Lebanon, New Jersey, it is an integrated heating and hot water system that has been in production for over 40 years. The core difference is the Hybrid Energy Recovery cycle: when a heating call ends, instead of letting residual heat escape up the chimney like a conventional boiler, the Energy Manager control redirects that leftover energy into the hot water storage tank or back into the home. This thermal purge cycle was tested at the Department of Energy's Brookhaven National Laboratory and documented to save up to 40% over boilers with comparable AFUE ratings.
For Long Island homeowners, this translates to lower fuel bills year-round, especially in the spring and fall shoulder seasons when heating demand is intermittent. The system also produces virtually unlimited hot water through a high-performance plate heat exchanger, eliminating the need for a separate water heater. And it runs on gas, oil, propane, or bioheat, making it one of the most versatile systems available for homes with or without natural gas service.
System 2000 does cost more upfront than a standard boiler. However, the combination of lower fuel consumption, the elimination of a separate water heater, and the lifetime pressure vessel warranty often make it the lowest total cost of ownership over 20 years. We can run the numbers for your specific situation during a free estimate.
Patented thermal purge cycle captures heat that other boilers waste. Proven at Brookhaven National Lab to save up to 40% beyond AFUE.
Combines heat and hot water in one system. Plate heat exchanger delivers virtually unlimited hot water. No separate water heater needed.
Heats up in about 90 seconds versus 8-15 minutes for cast iron. No energy wasted maintaining temperature when the system is idle.
Runs on natural gas, oil, propane, or bioheat. Can be converted between fuels with a simple burner change. The rest of the system stays the same.
Energy Kinetics claims 30 of their boilers running simultaneously are quieter than one conventional oil boiler. Homeowners consistently confirm this.
Built by a family-owned company in Lebanon, New Jersey. Gasketless, one-piece steel pressure vessel designed to outlast cast iron construction.
System 2000 installations on Long Island typically range from $10,500 to $14,500 for a residential Frontier or Resolute model with storage tank. The Accel CS condensing model runs higher, typically $13,000 to $17,000 installed, due to the advanced condensing technology and 316L stainless steel construction.
This is a higher upfront investment than a standard boiler like a Peerless or Burnham, but System 2000 is replacing both your boiler and your water heater in a single installation. When you factor in the cost of a separate indirect water heater ($1,500 to $2,500 installed), the price gap narrows significantly. The ongoing fuel savings from the thermal purge cycle and lower hot water costs often make up the difference within a few years.
All Accel CS and Resolute models qualify for National Grid rebates and federal tax credits. Frontier models with qualifying AFUE ratings are also eligible. We offer flexible financing through Wisetack. For a full cost comparison by system type, visit our cost guide.
If you already have a System 2000 and are happy with how it performed, the newer models offer even better efficiency. The Accel CS condensing model achieves up to 97% AFUE with 316L stainless steel construction. The Resolute offers 90+ AFUE with sidewall venting capability, which eliminates the need for a traditional chimney. And the current Frontier series includes the updated Energy Manager digital control for smarter operation.
Some homeowners prefer to switch to a separate boiler and indirect water heater setup when their System 2000 reaches end of life. This is a valid approach, and we can compare both options during your estimate. Brands like Weil-McLain, Navien, or Burnham paired with an indirect tank are good alternatives if you want that flexibility.
For homeowners replacing a different brand of boiler and considering System 2000 for the first time, the integrated design means fewer components to fail over the life of the system. There are no cast iron sections or gaskets to leak, no separate water heater to maintain, and the pressure vessel carries a lifetime limited warranty that is transferable to a new homeowner.
System 2000 installation is more involved than a standard boiler swap because it is an integrated system. Here is the process from start to finish.
We evaluate your current setup, calculate your heating load, and determine which Energy Kinetics model fits best. We review all rebates, tax credits, and financing options before you decide.
Once approved, we schedule at your convenience. System 2000 installations typically take one to two days depending on whether you are replacing an existing System 2000 or converting from a different type of boiler.
Our crew removes the old equipment, installs the new Energy Kinetics boiler and storage tank, connects piping, venting, and the Energy Manager control. We program the system for your specific zones and hot water needs.
We register your warranty with Energy Kinetics, submit rebate paperwork, verify combustion efficiency, and walk you through the system operation. Your lifetime warranty coverage begins immediately.

Long Island homeowners share their experience with Energy Kinetics installations by our team.
"Our old System 2000 ran for 22 years without a single breakdown. When it was finally time, Domino's installed the new Frontier EK1 and the difference is noticeable. The new Energy Manager is smarter, the hot water recovery is faster, and the unit is even quieter than our old one. Oil bill went down about 20% the first winter."
"We replaced a 30-year-old cast iron Weil-McLain and a separate water heater with an Accel CS. The gas savings have been substantial, and the endless hot water is the part my family notices most. It cost more than a regular boiler, but we got rid of the water heater too, so the math worked out well."
"Our chimney needed major work, so Domino's recommended the Resolute with sidewall venting. That saved us the cost of a chimney reline and the boiler runs on oil through a simple polypropylene pipe through the wall. The thermal purge cycle is real. You can actually feel the radiators stay warm for 15 to 20 minutes after the burner shuts off."
