THE HELIX VLT CONDENSING BOILER uses a vertically mounted, helical fin tube heat exchanger made of 316L/444 stainless steel. The self-cleaning design has wide, smooth waterways that help remove hard water deposits and prevent scaling. It delivers an EnergyStar rated 96% AFUE, and features sealed combustion, built-in outdoor reset, built-in low water cut-off, and a corrosion-resistant CPVC flue collector. The sealed housing reduces noise for quiet comfort in the living space. The boiler is rigorously tested prior to shipment, and the heat exchanger is backed by a 15-year limited warranty.
