Weil-McLain takes condensing boiler technology to a higher level of performance. The Ultra Series 4 features a state-of-the-art heat exchanger with nanotechnology coating that works like "Ultra Armor", reducing build up in the heat exchanger while maintaining high efficiency. Inspired by nature Clean-free for at least 5 years* Nanotechnology was created to mimic the lotus effect, preventing water condensate build-up.

3 1 High Efficiency and Environmentally Friendly How high heating costs fall to Ultra technology As fuel costs soar, home heating efficiency is on the mind of virtually every homeowner. For gas fired appliances, Ultra boilers employ an advanced mono-block aluminum heat exchanger that transfers heat faster than conventional materials. All Ultra boilers feature a high AFUE efficiency level.
