Weil-Mclain Ultra 310 Serie 2 Boiler Details
The Weil-Mclain Ultra 310 Serie 2 Boiler represents an innovative combination of sophisticated appearance, intelligent operation, and advanced technology. Its modern design ensures suitability for installation in diverse settings, from utility rooms to more visible spaces. This boiler is not only aesthetically pleasing but also engineered for superior performance and efficiency, setting it apart in the market.
Achieving over 92% AFUE and up to 98% efficiency in low-temperature applications, the Ultra 310 Serie 2 significantly surpasses Department of Energy's ENERGY STAR requirements. This high efficiency translates into considerable energy savings and reduced operational costs for homeowners. Its robust performance ensures consistent heating output even under demanding conditions, providing comfort and reliability.
At the heart of its intelligence is PhD Technology, a proprietary system that precisely manages hydronic heating and hot water needs. This intelligent control module measures and responds to various system data parameters, including room thermostat, supply/return water temperatures, flue gas temperature, domestic hot water aquastat, and outdoor temperature. This continuous monitoring allows for dynamic adjustments to optimize heating.
The boiler’s high-tech features include a cast mono block aluminum heat exchanger, designed for durability and quick heat transfer. This low-mass exchanger ensures faster heating, delivering warmth to the system more rapidly than conventional designs. Its construction is specifically engineered to excel in low return temperature condensing applications, maximizing energy recovery and overall system efficiency.
A sophisticated burner system, featuring a pre-mix stainless steel burner, enables a wide 20-100% modulating firing rate. This precision allows the boiler to match heating demand closely, preventing wasteful on/off cycling. The burner ensures quiet operation, high efficiency, and clean combustion, contributing to lower NOx emissions and exceeding stringent environmental codes like California’s Rule 1146.2.
Installation convenience is a key design aspect of the Ultra 310 Serie 2. It requires minimal clearance and floor space, offering flexibility for both floor-standing and wall-hung applications. Water and gas piping are thoughtfully arranged for easy connection, primarily at the top for floor-standing units, simplifying the setup process for qualified installers.
Electrical components come pre-wired and clearly labeled on separate line and low voltage terminal strips, facilitating quick and error-free field wiring. The use of PVC for both exhaust and combustion air venting streamlines the venting process, eliminating the need for messy sealants and allowing for vent runs up to an equivalent of 100 feet. This reduces installation complexity and time.
For enhanced domestic hot water production, the Ultra 310 Serie 2 seamlessly integrates with Weil-Mclain Ultra PLUS Indirect-Fired Water Heaters. The boiler's control module features standard domestic hot water priority control, ensuring quicker response times and faster recovery for hot water demands, making it an ideal companion for high-demand households.
Further demonstrating its commitment to user and service technician convenience, the boiler includes a side-mounted service receptacle on a dedicated circuit. This feature provides an accessible power source for condensate pumps, service equipment, or work lights, enhancing safety and ease during maintenance or troubleshooting procedures.
The Ultra 310 Serie 2 is also commendably environmentally friendly. Beyond its high efficiency, it produces significantly less NOx, meeting and exceeding all current environmental codes. This dedication to clean combustion reinforces its position as a responsible and high-performing heating solution for modern homes and businesses.
