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. The SlimFit is one of the most versatile, powerful, and efficient boilers on the market. Clocking in at 1,500,000 BTU with a thermal efficiency of 95.8%, the SF1500R can bring excellent energy savings to the largest of applications. Designed to be simple to install, maintain, and operate, the SlimFit represents peace of mind in addition to comfort. Fully packaged and ready to install, the SlimFit's durable components and easy-to-use Sola controls round out what is one of the most impressive boilers in the marketplace. Ideal for every application from augmenting existing heating systems to headlining new construction, the SlimFit is one of the best values in heating.
Cast-Aluminum Heat Exchanger
The Weil-McLain SlimFit 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 SlimFit from corrosion related to condensation.
Outdoor Reset Control
An outdoor reset sensor is included with every SlimFit boiler. This sensor, when paired with the Sola control system, allows your boiler temperature to be adjusted relative to the temperature outside, eliminating excess energy use and guaranteeing comfort.
Industrial Power, Amazing Efficiency
The SlimFit brings condensing technology and a modulating burner to industrial scale heating. These features bring efficiency gains in the form of reusing heat that escapes traditional boilers and scaling heat production precisely to your needs, respectively.
A low profile and two venting options, direct vent and direct exhaust, mean that the SlimFit can accommodate nearly any installation requirements. Removable wheels on the SlimFit's frame provide a safe, simple way to get your boiler into position.
The Sola control has a large touchscreen to make navigating the menus simple and it can connect to Modbus communications systems for remote access to your heating system. The Sola isn't just for controlling the SlimFit, it also relays information about usage trends so that you can stay informed about your hydronic heating system.
Easy Application Expansion
The SlimFit's Sola control can stage and rotate up to eight boilers. Whether you want to add another SlimFit boiler or you are adding the SlimFit to an existing application, the Sola can handle integration. The SlimFit truly shines in hybrid systems where its modulation provides increased efficiency during low-load times and the conventional boilers provide extra power during high-load times.
