ARUBA 3 is CROWN's best selling gas-fired, hot water boiler. It comes in a wide range of sizes from 37,000 to 295,000 BTU/HR input.
Crafted with a rugged, cast iron heat exchanger and stainless steel burners that are both backed by a lifetime limited warranty, the ARUBA 3 offers proven-in-service reliability, simplicity of design and economy in its purchase price and consumption of fuel.
The ARUBA 3 is available with standing pilot or electronic ignition for greater energy efficiency. Honeywell controls provide reliability, ease and convenience.
Attractive and durable, the two-tone, powder-coated jacket resists scratching. Plus, it's insulated to retain heat. The ARUBA 3 meets all national standards, and the heat exchanger meets the specifications of the American Society of Mechanical Engineers.
