The Aruba 4 Series (AWR) residential, cast iron, hot water boiler is a fully-packaged, installer-ready product. The rear draft diverter provides a low profile design that allows for closet applications on AWR models through the AWR210. This atmospheric, gas-fired boiler is for use with a conventional chimney fueled with natural or LP gas. The Aruba 4 features a standardized Honeywell Intermittent Ignition System.

The Aruba 4 comes with an Integrated Boiler Control with temperature control, relay, and ignition functions in a single module. This includes an additional circulator output for a second heating zone or an indirect water heater like the Mega-Stor. All controls are located inside the front vestibule, creating a clean look and space efficient design. With the controls located in the front of the boiler and supply/return tappings on both the left and right side, the Aruba 4 has flexible installation options to fit most locations.

This wall-mounted condensing boiler has a stainless steel water tube heat exchanger, and is one of our most efficient offering. The Phantom is available in five sizes (80, 100, 120, 150, and 180 MBH) with multiple venting options. The Phantom offers “Smart Boiler” capabilities, like outdoor reset and a modulating burner with 5:1 turndown ratio. A Honeywell SOLA control with a touchscreen user interface comes standard, as does low water cutoff, and side panel access to the circulator makes this boiler a serviceman’s dream.
