Features

    Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Weil-McLain's Ultra hot water boiler is highly efficient, simple to install, and remarkably durable. Using condensing technology, the Ultra will reuse heat that escapes from conventional boilers, providing greater efficiency. When equipped with the optional Weil-McLain Advanced Features Module (AFM), the Ultra is a very user-friendly boiler. A clear display screen relays information about operations, temperatures, and system status. With AFM and an 87% AFUE, the Ultra UO-3 makes comfort and efficiency more accessible than ever before.
  • Modern Appearance
  • The Weil-McLain Ultra Oil has appliance-like design features that allow placement in high traffic living spaces as well as providing easy serviceability.
  • Swing-Away Door
  • Featuring a full access, reversible swing-away door, the Ultra Oil provides simplified inspection, cleaning and maintenance.
  • Three Pass Design
  • The three pass design, used by Weil-McLain for over 70 years, provides better flame control and efficient fuel utilization.
  • Concealed Controls
  • The Ultra Oil, with it's top mounted hinged control POD, includes a factory installed external service switch and temperature and pressure gauge for easy viewing.
  • Venting Flexibility
  • The Weil-McLain Ultra Oil can be vented to an existing chimney or direct vented using the pre-packaged termination and combustion air kit.

Medium Learn More
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Heat Exchanger Material
Cast Iron
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Oil
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
Modulating/Staging Learn More
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More
