The WeatherMaker® Series boiler provides more responsive heating and greater thermal storage for better heating comfort. Thanks to a revolutionary cast aluminum heat exchanger, the BW9 transfers heat three times faster than a conventional boiler with a cast iron heat exchanger. It delivers indoor weather comfort right when you need it!

Faster heat transfer of the WeatherMaker® Series boiler helps lower fuel consumption and boosts the Annual Fuel Utilization Efficiency to 90%! The cast aluminum heat exchanger not only helps improve your indoor comfort, it also helps lower your operating costs by using fuel more efficiently. And that should make you just a little more comfortable when the utility bill arrives!

Along with the sophisticated heat exchanger, the WeatherMaker® Series boiler features easy installation and maintenance. The WeatherMaker® Series boiler is easily installed using PVC pipe for both air intake and exhaust. Additionally, all components are easily accessible and tied to a self-diagnostic system that reduces the time it takes for routine service calls.

The WeatherMaker® Series boiler is perfect for new home construction and replacement installations. Weighing just 220 pounds, the WeatherMaker® Series boiler installs quickly and easily. It’s the ideal heat source for traditional radiator or radiant panel systems. And, coupled with an integrated boiler control, you will experience the responsive heating and reliable operation that earns the name "Carrier."
