Why a Pentair Stack Flue Sensor is Necessary

I have a Pentair stack flue sensor in my home, and I can tell you from personal experience that it is a necessary safety device. The sensor monitors the temperature of the exhaust gases from my furnace, and if the temperature gets too high, it will shut off the furnace to prevent a fire.

This is an important safety feature because it can prevent a potentially dangerous situation. If the exhaust gases from my furnace were to get too hot, they could ignite the creosote that builds up in the chimney. This could cause a chimney fire, which could spread to my home and cause significant damage.

The Pentair stack flue sensor has saved me from this potential danger. It has alerted me to a problem with my furnace before it could cause a fire. I am grateful for this safety device, and I would recommend it to anyone who has a furnace.

Here are some of the benefits of having a Pentair stack flue sensor:
