Features
- Cast Iron Heat Exchanger
- The Crown FW includes a durable cast iron heat exchanger that circulates hot flue gases through the heat exchanger three times, resulting in a more efficient boiler.
- Durable Jacket
- A powder coated, textured and insulated jacket allows the FW to provide powerful heating in even the toughest conditions.
- Venting Options
- Pressurized for forced draft or chimney draft venting, the FW is able to adapt to your installation requirements.
The Crown FW is a cast iron, scotch marine-style boiler for use with light oil, gas, or a light oil-gas combination. Featuring a cast iron, 3-pass heat exchanger, the FW is designed to maximize heat transfer from flue gases to the boiler water. The FW includes cast iron push nipples and boiler sections, woven glass ropes between sections, swing open burner door and removable stainless steel baffles. Exclusively designed for forced hot air circulation, the FW boasts impressive BTU output while using as little energy as possible.

Medium
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
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/Natural Gas
Combustion Type
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
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
DHW Production
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
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

DOE Heating Capacity
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.
355000 BTU
Net I=B=R Capacity
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.
309000 BTU
Thermal Efficiency
84.5 %
Ultra Low NOx Emissions
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. Learn More
