The Weil-McLain Ultra® Gas Series 4 is a high-efficiency condensing gas hot-water boiler with a wide BTU range — from 80,000 to 299,000 BTU/hr. This makes it one of the most versatile residential boilers in the Weil-McLain lineup, suitable for small condos, large single-family homes, and multi-unit buildings.
Like all condensing boilers, the Ultra Gas Series 4 extracts heat from flue gases that standard boilers waste, achieving 95% AFUE. Its stainless steel heat exchanger is designed to handle the acidic condensate produced during this process, ensuring long-term reliability.
D's Air & Heating, Inc. installs the Ultra Gas Series 4 throughout Chicago and the southwest suburbs. We pull all required City of Chicago mechanical permits, handle all piping and controls, and register your Weil-McLain warranty at startup.
