Automatic Septic System Heater
A lot of septic systems have frozen up during the past couple of winters in the northern states and Canadian provinces due to light snow cover. A Minnesota inventor says his new septic heater automatically solves the problem.
  Chris Norgaard came up with the idea after his own septic tank froze two winters ago.
  The unit consists of a 38-in. long, 4-in. dia. poly tube enclosing a fan and heater as well as a 3-in. dia. stainless steel pipe. The bell end of the tube slides over the access pipe above a septic tank, lift station, or drop box in the drainfield of a septic system. It blows warm air down into the system. The air is naturally vented out the existing main vent of the home or cabin. (If the system has 6-in. dia. riser pipes, an adapter is needed).
  The heater turns on and off automatically based on a waterproof sensor that hangs a couple feet down into the pipe. The heater activates based on the temperature of the water in the drop box or the temperature of the tank and is activated when temperature drops to 35 degrees. It blows 140 degree air into the septic system. Once the temperature reaches 45 degrees, the heater turns itself off.
  Indicator lights on the outside part of the pipe allow you to see if the heater is working without leaving the house.
  "It takes just minutes to install," says Norgaard. "We designed the system a year ago and placed 13 units throughout Minnesota and Alaska last winter for testing, with positive results. It's a lot more dependable than placing hay or straw over the septic system and also a lot less work. It sells for $795 including S&H. However, it can cost a lot of money to have someone come out to pump out your septic tank or jet or steam the pipes. You don't have to worry about damage to the septic system or to your basement. And you gain the peace of mind by knowing you can go somewhere during the winter without worrying that your septic tank will be frozen when you come back."
