Weil-Mclain Ultra 105 Serie 2 Boiler Details
The Weil-McLain Ultra 105 Serie 2 Boiler features an innovative design, blending advanced intelligence with cutting-edge technology. It boasts a sleek, attractive aesthetic suitable for diverse installations. Central to its operation is PhD Technology, an intelligent system ensuring Precision Hydronic heating. This system dynamically measures and responds to various data parameters within your heating setup, thereby maximizing efficiency for both space and hot water needs.
At its core, the boiler incorporates high-tech components, including a robust cast mono block aluminum heat exchanger. Coupled with a sophisticated gas valve, blower, and venturi technology, the system constantly maintains an optimal air-to-fuel ratio across all firing rates. The specialized venturi mixing body precisely blends air and gas, contributing significantly to its overall high efficiency. This meticulous engineering ensures consistent, reliable performance.
The Ultra Control Module provides the system's intelligence, integrating inputs from room thermostats, supply and return water temperature sensors, flue temperature sensors, and even an outdoor temperature sensor. It also manages domestic hot water (DHW) aquastats and summer/winter switches. This comprehensive data allows the module to automatically adjust blower speed and gas flow, modulating the boiler's firing rate to closely match heating or DHW demands.
A unique cast aluminum mono block heat exchanger defines the Ultra 105. Its low-mass design facilitates faster heating, delivering warmth to your system more quickly. This particular aluminum block is engineered specifically for low return temperature applications, excelling in condensing operations. The pre-mix stainless steel burner, featuring a woven steel fiber mesh, offers a remarkable 20% to 100% modulating firing rate. It ensures longevity, quiet operation, high efficiency, and exceptionally clean combustion with low NOx emissions.
Installation of the Ultra 105 is designed for ease, requiring minimal clearance and floor space. It offers flexibility for both floor standing and wall hung applications, despite some model-specific notes on wall mounting kits. Water and gas piping are conveniently arranged for connection at either the top or bottom. Electrical components come pre-wired with labeled terminal strips, simplifying field connections. Furthermore, PVC venting allows for simplified exhaust and combustion air runs up to an equivalent of 100 feet without messy sealants.
For enhanced domestic hot water performance, the Ultra 105 pairs perfectly with Ultra PLUS Indirect-Fired Water Heaters, available in 40, 60, and 80-gallon sizes. This combination provides ample hot water and leverages the boiler's high efficiency. The Ultra boiler control module includes standard DHW priority control, ensuring quicker response times and faster recovery for the hot water tank. A convenient side-mounted service receptacle, on a separate circuit, is provided for auxiliary equipment.
The boiler is notably lightweight compared to conventional models, featuring side jacket handles for easier transportation and four adjustable feet for effortless placement and leveling. Beyond its high efficiency, the Ultra 105 is an environmentally friendly choice. It exceeds ENERGY STAR program requirements and produces significantly less NOx, making it certified by the South Coast Air Quality Management District (Rule 1146.2) in California. The product also comes with a limited 15-year heat exchanger warranty and a 5-year parts and labor homeowner protection plan.
