    "Uncover warm possibilities" with Williamson-Thermoflo's OWT Oil fired water boiler with tankless. The highly efficient OWT-3-T-S2-W pumps out 114,000 BTUs with a thermal efficiency rating rating of 85 percent. The OWT is also designed with a solenoid valve, PSC motor, and a solid state igniter to maintain that efficiency. This boiler is equipped with many features, such as a temperature limit control, cast-iron sections with built-in separator, and an insulated heavy-gauge steel jacket. The OWT is also easily serviced with a swing-away burner door, top access cleanout cover, and plug-in wiring harness. Since it is factory tested and comes with a limited lifetime warranty on the heat exchanger, you can be absolutely sure that your investment is reliable and built to last.
  • Factory Tested
  • OWB boilers are factory tested, ensuring reliability and properly functioning equipment.
  • Factory Assembled
  • OWT boilers are factory-assembled meaning that the boiler comes ready for installation. This includes the aluminized flue collector, swing-away burner mounting door, with the refractory blanket and recessed target wall in the combustion chamber.
  • Easy Service
  • With a swing-away burner door, top access cleanout cover, and plug-in wiring harness, servicing the OWB boiler easy.
  • Product Includes
  • Taco 007 Circulator Pump

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.

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.
