Weil-Mclain Ultra 80 Serie 2 Boiler Details
The Weil-McLain Ultra 80 Series 2 Boiler stands out with an innovative blend of aesthetics, intelligence, and advanced technology. Its design is thoughtfully crafted to be appealing, allowing for seamless integration into various installation settings. This model achieves exceptional efficiency, surpassing 92% AFUE, and can reach up to 98.1% efficiency in low-temperature applications, making it a highly economical choice for heating needs.
At the core of its intelligence is the PhD Technology, an advanced system that precisely manages hydronic heating and hot water demands. This intelligent control module measures and responds to various system parameters, continuously optimizing efficiency. It meticulously tracks inputs from the room thermostat, supply and return water temperature sensors, and the flue temperature sensor.
The boiler features a high-technology cast mono block aluminum heat exchanger, designed for robust performance in low-temperature condensing environments. This low-mass exchanger ensures faster heating, delivering warmth to your system more quickly than conventional designs. Its sophisticated gas valve, blower, and venturi technology work in concert to maintain an optimal air and fuel ratio across all firing rates.
Further enhancing its high-tech profile, the Ultra 80 employs a pre-mix stainless steel burner, specifically engineered for precise firing rate modulation from 20% to 100%. This design ensures superior efficiency, exceptionally clean combustion, and quiet operation, contributing to a comfortable and environmentally friendly heating solution.
Installation is notably simplified, requiring minimal clearance and floor space, and offering flexibility for both floor standing and wall hung configurations. Water and gas piping connections are conveniently arranged at either the top or bottom of the boiler. For floor standing setups, most connections are accessible from the top, except for the condensate drain.
The electrical components come pre-wired and labeled on separate line voltage and low voltage terminal strips, facilitating quick and easy field wiring. Venting is streamlined through the use of PVC for both exhaust and combustion air, requiring no messy sealants and accommodating vent runs up to the equivalent of 100 feet.
For enhanced domestic hot water (DHW) production, the Ultra 80 pairs perfectly with Ultra PLUS Indirect-Fired Water Heaters. The boiler's control module includes a standard DHW priority control, ensuring faster response times for hot water demands and quicker recovery of the storage tank. The unit also features a side-mounted service receptacle on a separate circuit, ideal for a condensate pump or service equipment.
The Ultra 80 boiler is lightweight compared to traditional boilers, featuring side jacket handles for easy maneuverability and four adjustable feet for straightforward placement and leveling. Beyond its high efficiency, the Ultra boiler is environmentally conscious, producing less NOx emissions thanks to its PhD Technology and advanced burner design, meeting stringent environmental codes.
