Boilers / Water Heaters - Sales & Repair

Sales & Installation

If you are looking for a hot water boiler or boiler sales and installation contractor, Four Seasons Chicago has you covered. By reducing your heating cost, Chicago land residents can enjoy water boilers at a minimized price.

The Series MI residential gas hot water boilers are cast iron, fully packaged and ready to install. This atmospheric gas-fired boiler is designed for natural draft use with a conventional chimney. The Series MI boiler is available with a standing pilot or intermittent ignition, and is available as natural or LP gas. The intermittent ignition is provided by the Honeywell SmartValve® System, which houses the safety and ignition functions in one device. Only when there is a need for heat does the ignition light the pilot, keeping cost low and eliminating the need for extra wiring and separate controls. The integral draft diverter provides a low-profile design, allowing the boiler to be installed in areas with low clearance. The Standard Honeywell controls are easily accessible making the Series MI boiler simple to install and service. Standard equipment includes a Taco circulator, a flame rollout safety shutoff switch and a vent safety shutoff switch. The Series MI boilers are energy efficient exceeding the 80% AFUE (Annual Fuel Utilization Efficiency) federal standard for residential boiler efficiency.
