How-To Articles


    Crown's Cayman line of boilers is designed to be an all-encompassing heating solution for homes ranging in size from a small condo to a full multi-bedroom household. The heat exchanger at its core is constructed of cast-iron, a material proven effective in hundreds of heating applications around the world. The footprint of the Cayman is smaller than average making it perfect for compact utility rooms, and it comes with a low-clearance vent opening to maximize venting flexibility and installation options. The key feature of the Cayman line is the included tankless water heater coil, an internal accessory that allows the boiler to provide domestic hot water for showers and kitchen needs while heating the air in your home at the same time.
  • Cast Iron Heat Exchanger
  • The heat exchanger at the core of the Cayman is made of durable cast iron, a material proven many times over for its reliability in heating applications and efficiency in heat transfer.
  • Built-In Tankless Coil
  • The Crown Cayman boilers come with a built-in tankless water heater coil, allowing the boiler to handle all of your domestic hot water needs without an external hot water tank. This also means that your home has an endless supply of hot water.
  • Low Clearance Draft Diverter
  • Crown's Cayman line of boilers come with a very low height draft diverter, allowing it to be installed in low height areas or in areas with complicated venting configurations.
  • Included Automatic Vent Damper
  • An automatic vent damper is included with the Cayman boilers. It regulates the exhaust gas flow from your boilers venting system, allowing more heat to be kept inside the boiler for increased efficiency.
