The Weil-McLain Ultra Series High-Efficiency Gas Boiler is a high-performance boiler part engineered to deliver premium hydronic efficiency and reliability. Built with a heavy-duty cast aluminum housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for residential, commercial, and industrial hydronic application loops.
Engineered as the centerpiece of advanced low-temperature condensing hydronic systems, the Ultra Series leverages state-of-the-art modulating burner configurations to eliminate short-cycling and lower fuel utility rates by up to 30%. The integration of an UltraArmor protective thermal block structure defends core passageways from corrosion and debris accumulation, sustaining high operational efficiency year after year. Equipped with intuitive multi-zone digital controls and outdoor temperature monitoring interfaces, this condensing system smoothly matches heat production to ambient load demands for uniform climate control.
Advanced Engineering Features:
- UltraArmor Nanotechnology Coating: Premium protective internal shielding acts as a barrier against scaling and harsh thermal cycling stresses to secure heat exchanger longevity.
- 5:1 Proportional Modulation Turn-Down: Advanced gas valve and variable-speed blower automatically scale performance down to 20% capacity to accurately fulfill small zone demands without wasting energy.
- U-Control Intelligent Logic Board: Comprehensive multi-circulator management screen monitors internal sensors and outdoor profiles, operating up to three unique temperature setpoints simultaneously.
