Freezing Temp Alert, Freeze Warn Light: Flashes Below 42°F Available in Red OR Blue (Red) Batteries Included

Wonderful product for my situation. At a glance at the window, I could see the light flashing that meant the boiler had failed again. Love it!

Easy enough

On time reasonable price

works as expected

used in pump house

Holy crap works great saved my friends house. They were going south for the winter I got it for them as a gif. I was coming home one day and it was flashing. went in and it was cold they ran out of propane called him and they got it filled it works great.

When we tested this light it works well. We have people who live near us were told about the light and watch for it. We have in have homes in Wisconsin and a winter home in Florida. Wis. gets really cold in winter.Our friends keep a eye out for the light and can call us or repairman if the light comes on.

Have not had a problem yet ,so have no idea

I gave this as a gift

This is the second winter I have used this light. Got a call last week saying the light is flashing! Good to know as when we had someone check it out the furnace wasnt working. Got a repair guy out and was able to get it running before anything was damaged for froze!
