Overview for Weil-McLain 383600330

Over the last 130 years, Weil-McLain has built the 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 550,000 BTU with a thermal efficiency of 93.9%, the SF550 can bring excellent energy savings to the largest of commercial 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 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.
  • 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.
  • Cast-Aluminum Heat Exchanger
  • The Weil-McLain SF550 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.
  • Outdoor Reset Control
  • An outdoor reset sensor is included with every SlimFit® boiler. This sensor allows your boiler temperature to be adjusted relative to the temperature outside, eliminating excess energy use and guaranteeing comfort.
  • Installation Versatility
  • A low profile and two venting options mean that the SlimFit® can accommodate nearly any installation requirements. The SlimFit's® compact size can be the perfect solution for installations with difficult access to tight spaces.
  • Perfect for Retrofits
  • The SF550 is designed to be easily integrated with older, non-condensing boilers; a perfect way to increase efficiency by creating a hybrid system. It also comes fully factory-assembled for quick, on-site installation.
  • Advanced Boiler Controls
  • A user-friendly interface, boiler scheduling, warm weather shutdown, frost protection, and maintenance reminders are a few of many features that come standard on the SlimFit®.
  • Ultra Low NOx
  • The SlimFit® series helps keep peace of mind and harmful emissions low by limiting NOx emission to less than 20 ppm.
  • Modbus® Connectivity
  • The SF550 features Modbus® connectivity, allowing for communication and control between up to 8 SlimFit® boilers and 24 circulators.
  • Product Includes:
  • (1) Weil-McLain SlimFit® SF550 Hot Water Boiler
  • (1) Outdoor Temperature Sensor
  • (1) Natural Gas to Propane Conversion 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
    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.
    Natural Gas
    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.
    Condensing
    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.
    Direct Vent
    DHW Production Learn More
    DHW Production
    DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

    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.

    AFUE Learn More
    AFUE
    AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace.

    Maximum Input Capacity Learn More
    Maximum Input Capacity
    The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.

    Minimum Input Capacity
    110000 BTU
    DOE Heating Capacity Learn More
    DOE Heating Capacity
    Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.
    517000 BTU
    Net I=B=R Capacity Learn More
    Net I=B=R Capacity
    I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.

    Ultra Low NOx Emissions Learn More
    Ultra Low NOx Emissions
    NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx.
