Homeowners enjoy economical heat, plus virtually endless hot showers with lower energy costs. It's a non-condensing 90+ AFUE in gas and oil models, and goes beyond AFUE with low idle loss for better delivered efficiency. 90+ Resolute is ideal for fin tube baseboard, cast iron radiators, air handlers, and unit heaters, complementing its exceptional performance with high efficiency and nearly endless hot water.
Oil - Natural Gas - Propane
AFUE does not accurately rate heat and hot water systems and misses significant areas of energy loss. There are tremendous opportunities to increase efficiency over AFUE estimates alone. The Department of Energy’s Brookhaven National Labs study demonstrates our design as the top performing system, saving up to 38% over boilers from around the world. The 90+ Resolute improves on the highest real efficiency of all systems tested, delivering even better peak and annual efficiency.
Energy Kinetics provides the best pressure vessel in the industry along with a lifetime limited warranty and a ten-year labor allowance for residential pressure vessels. This is backed by a track record of over 35 years of proven, industry leading pressure vessel longevity. The warranty can be transferred to a new owner within the first five years of the installation. The Digital Energy Manager carries a 5-year warranty and an extended protection plan for the life of your 90+ Resolute. Refer to the specific warranty for details.
90+ Resolute can vent with a polypropylene flexible chimney liner, or be sidewall vented for gas or oil systems. Both are excellent options instead of repairing an existing chimney or installing an expensive stainless steel chimney liner. With 90+ Resolute’s unique combustion chamber, combined with a nearly 15-foot long flue passage, gases leave clean, and relatively cool. So they can be vented directly through-the-wall.
