WASTE OIL HEATERS - BOILERS BY ALTERNATE HEATING SYSTEMS
The B Series Waste Oil Heater - Boiler
The B Series waste oil heater/boiler design is tried and true. The design has been in operation for over 18 years with a spotless record. Even after 18 years, our B Series design is
still the most state-of-the-art waste oil heater/boiler design on the market.




What makes the B Series Waste Oil Boiler's design different from our competitors:
  • An Airflow-inducing Fan causes the ash to be pulled through the boiler at high speeds keeping it from depositing on the burner wall. It also allows adjustment of the airflow according to the desired BTU.
  • The Swirl Chamber is a high pressure area in the burner that allows hot exhaust to reside for a long period of time. Coupled with a swirling motion, which gives the burner the ability to drop the temperature of the exhaust from 1,800 degrees to as low as 350 degrees (see below) before it is allowed to exit the burner, THE SWIRL CHAMBER IS OUR KEY TO HIGH EFFICIENCY COMBUSTION OF
    WASTE OIL .
  • The Cyclone Ash Collection System does the major part of the self-cleaning action of our waste oil burner - the rapidly moving ash acts to scour the walls of the inside of the burner preventing buildup and providing a self-cleaning action.  The cyclone funnels the ash into a pail for easy disposal.
  • A Secondary Air Inlet allows oxygen to enter the burn target for secondary combustion - any un-combusted waste oil remaining in the flue gases is provided another opportunity to be completely combusted.

Common Features of Our Waste Oil Heaters - Boilers:
Boilers and storage tanks can be custom tailored for your special applications.
Whether for recycling used oil or burning fuel oil (or both), we can size a cost-effective system for you.

Double savings means fast payback.
Heat your facility and generate hot water without cost while eliminating the liability and expense of contract off-site disposal.

EPA approved for recycling used oil.
On-site recycling is the preferred method of avoiding liability and reusing energy to enhance your bottom line.

Optional Waste Oil Heater Accessories Include:
  • Our base Waste Oil Heater may be purchased without the burner.
  • Controls and modifications for steam.
  • Hot water coils - 5 gpm, 6 gpm or 12 gpm.
  • 4" fitting for coil includes 4" pipe plug.
Stack Temperature
The stack temperature is an indicator of how completely the waste oil is being combusted. The Alternate Heating Systems Inc. B Series operates with one of the coolest stack temperatures of any waste oil heater/boiler on the market (we believe that it is actually the coolest). Because of the nature of the fuel, the stack temperature will vary. The low stack temperatures of our boilers are almost unheard of on the market.
