Over the last 130 years Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing long-lasting heating solutions is seen in every boiler they make. Weil-McLain’s Ultra hot water boiler is highly efficient simple to install and remarkably durable. The Ultra is a brilliant addition to any hydronic heating system and the low profile means that it is easy to fit into even the smallest of spaces. Using condensing technology the Ultra will reuse heat that escapes from conventional boilers providing greater efficiency. Equipped with Weil-McLain’s proprietary U-Control system the Ultra is a very user-friendly boiler. Clear display screens relay information about operations temperatures and even the maintenance schedule and your contractor’s contact information. With U-Control and a 94% AFUE the Ultra 155 makes comfort and efficiency more accessible than ever before. Nano-Coated Heat Exchanger With a nano-coated heat exchanger the Ultra boilers won’t need cleaning for 5 years after installation. When it comes time to clean simply rinse the exchanger with water and replace. Outdoor Reset Control An outdoor reset sensor is included with every Ultra boiler. This sensor when paired with the U-Control system allows your boiler temperature to be adjusted relative to the temperature outside eliminating excess energy use and guaranteeing comfort.
