 Earn double savings by eliminating…

…the disposal costs of used oil and the free heat and hot water for your business give you double the return on your investment. The PT-Series is an excellent option for smaller businesses desiring to convert the burden of waste oil disposal from a liability to a bottom-line enhancing asset. Our reputation for crafting quality heating systems will allow you to reap these savings for years.

The Story

The PT boilers result from a collaboration between Alternate Heating Systems and our dealers in response to a demand for high-quality, highly efficient, state-of-the-art, durable waste oil boilers that did not carry such a hefty state-of-the-art price tag. The PT-Series is based on our B-Series Premium Waste Boilers and is engineered with ease of maintenance and routine cleaning in mind. The PT Waste Oil System is a quality-built alternative to larger, more expensive waste oil systems.

The Burden

Our waste oil boilers are compatible with a variety of waste oil burners and can burn a variety of waste oil fuels, including crankcase oil, gear oil, transmission fluid, hydraulic fluid, fuel oil, and vegetable oil; these boilers offer a one-stop solution for saving on heating costs and solving your waste oil disposal problems. Disposing of motor oils and petroleum-based fluids from internal combustion engines has traditionally been a burden. The effects of improper disposal can be devastating to the environment. One quart of waste oil can pollute over 250,000 gallons of water, and cleanup is impossible. Waste oil is toxic and carcinogenic and can be a fire hazard if improperly disposed of. The EPA’s method of choice to dispose of used oils is on-site recycling.

Features of the PT-Series:

  • Heavy duty construction
  • ASME certification
  • Oversize heat exchanger delivers efficient operation all year long
  • Refractory lining and a Target Plate offer protection and combustion at very high temperatures.
  • Large access ports for easy access to burner end and flame viewing
  • Large access doors provide easy access to all parts of the boiler for maintenance and cleaning
  • Boilers and storage tanks can be custom-made for your unique applications

Engineered for incredible efficiency, our Waste Oil Boilers are the most state-of-the-art design on the market, excelling over competing brands for over 25 years.
