Crown Aruba

The Crown Aruba is the economy choice for steam system replacements. When budget is the primary concern and the existing steam radiators are in good condition, the Aruba delivers reliable performance at the lowest cost. We install these frequently in Hempstead, Roosevelt, and Uniondale multi-family properties.

At 82% AFUE, the Aruba uses older technology—but that simplicity means any technician can service it. Parts are universally stocked at every local supply house for same-day repairs.

Heavy cast iron construction is specifically designed for steam applications, handling the thermal cycling without cracking. The wide BTU range (70,000-196,000) suits various home sizes.

The 20-year heat exchanger warranty provides solid coverage for the straightforward cast iron design.

Our recommendation: The Aruba is the right choice when steam boiler replacement budget is tight and the priority is keeping heat flowing reliably. For homeowners willing to invest more, higher-efficiency options provide better long-term value.

Steam boilers like the Aruba are sized to the connected radiation — we measure every radiator's EDR rating and match the boiler's steam output to that total, plus piping pickup allowance. Square footage rules of thumb don't apply to steam.

Every Crown Boiler installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, gas or oil supply sizing, and permit requirements for your town.
