Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing long-lasting heating solutions is seen in every boiler they make. Weil-McLain's Ultra hot water boiler is highly efficient, simple to install, and remarkably durable. The Ultra is a brilliant addition to any hydronic heating system, and the low profile means that it is easy to fit into even the smallest of spaces. Using condensing technology, the Ultra will reuse heat that escapes from conventional boilers, providing greater efficiency. Equipped with Weil-McLain's proprietary U-Control system, the Ultra is a very user-friendly boiler. Clear display screens relay information about operations, temperatures, and even the maintenance schedule and your contractor's contact information. With U-Control and a 94.1% AFUE, the Ultra 299 CT makes comfort and efficiency more accessible than ever before.
Cast-Aluminum Heat Exchanger
The Weil-McLain Ultra utilizes a cast-aluminum heat exchanger. The heat transfer properties of cast aluminum are superior to those of stainless steel; it heats faster and transfers that heat very efficiently. A condensate trap and drain system protects the Ultra from corrosion related to condensation.
Outdoor Reset Control
An outdoor reset sensor is included with every Ultra boiler. This sensor, when paired with the U-Control system, allows your boiler temperature to be adjusted relative to the temperature outside, eliminating excess energy use and guaranteeing comfort.
Clean, Efficient Burner
The Ultra 299 CT has a stainless steel, modulating burner with a woven steel fiber mesh. Modulating burners scale heat production to your boiler's demand, further improving energy efficiency. A venturi mixing body ensures the ideal mixture of fuel and air for your burner. Pre-mixing results in cleaner burning, making the Ultra a low NOx boiler.
Weil-McLain's U-Control makes it simple to set up even the most complex applications. Preset system configurations may be used right out of the box or customized to your liking. The U-Control supports zoning with up to three setpoints and multiple Ultra boilers may be staged together through it.
The U-Control is not the only design element that makes the Ultra easy to install. Weil-McLain included piping at the top and base of the unit to provide flexibility in how you install the Ultra. All electrical components come pre-wired, color-coded, and connected to the U-Control. Even venting is simplified; a flue pipe adaptor at the top of the unit eliminates the need for sealant.
