Energy Kinetics 90+ Resolute Boiler Overview

The Energy Kinetics 90+ Resolute is a non-condensing steel boiler with an efficiency of 91% AFUE. The 90+ Resolute was an Energy Star 2015 Most Efficient product and is oil-fired, with easy conversion to natural gas or propane. The unit uses a stainless steel side tank vessel to produce hot water and comes with a 5-zone control, easily upgradable to 12 zones. It can be vented with a flexible polypropylene chimney liner or directly through the wall. The 90+ Resolute uses Hybrid Energy Recovery to send heat that remains after shutdown to the top of the hot water storage tank or into living spaces for greater efficiency. The unit’s jacket is insulated to reduce both heat loss and operating sound levels.
