  • The Thermo-Disc is made to fit manhole risers with an inside diameter of 23.5 inches to 24.25 inches.

    Custom sizes may be available upon request.

  • No, the Thermo-Disc can remain installed the entire year without causing any harm.

  • Yes, the Thermo-Disc can be easily removed in seconds by you or your septic system maintainer.

  • The Thermo-Disc is specifically designed to keep the cold air out and warm air in the tank.

    An insulated manhole cover may be helpful but does not prevent the cold from penetrating through the risers and into the tank.

    The Thermo-Disc is designed to be installed as low as possible in the riser, providing an insulation barrier preventing the cold from entering the tank.

  • Our patented technology is an elegant solution to a pressing problem for septic tank owners in cold winter climates.

    We provide peace of mind for homeowners to avoid the expense and hassle of a frozen septic tank.

    Our mission is to deliver exceptional customer support, along with our innovative septic tank part.

  • The Thermo-Disc has a seal that helps reduce or eliminate odors from escaping through the manhole.

  • The Thermo-Disc is made of non-corrosive materials and should last a very long time.

  • You pay your heat bill every month; you buy your insulation once.

    Instaling Thermo-Disc before your tank freezes is an investment in avoiding a costly, annoying repair down the road.

  • The treatment and effectiveness of a septic system are drastically reduced when the temperature of the sewage is below 40 degrees Fahrenheit. The Thermo-Disc will help keep the sewage warmer, which will increase the effectiveness of the treatment process.
