Crown Boiler
Crown Aruba3-AWI Boiler
Gas-fired hot water boiler
Perfect for residential and light commercial applications with chimneys
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.
ARUBA 3 is the latest in a series of designs that CROWN engineers have created for ease of use, constructed for long life and engineered to provide the most value for each energy dollar. That's CROWN's commitment to quality.

Boiler News
NTI’s Matrix is the first integrated appliance to not only qualify for the new CSA P.10 efficiency standard, but to exceed the requirements for its “Premium” performance designation. The Matrix, which incorporates a condensing water heater, furnace and boiler, heat recovery ventilator, and which is pre-wired for air conditioning, is a powerful, one-of-a-kind energy device.
In recognition of its achievements with the Matrix, NTI was honoured as the first recipient of Natural Resources Canada’s new eKOCOMFORT Award. The award recognizes manufacturers whose products meet the new CSA P.10 performance standard.
