Here is a review of a GQF 0470 Thermostat Controlled Radiant Heater that was requested. I've had the heater about a week now and really like it. It has a wafer thermostat control like the Hovabator incubators and a low voltage light to attract birds at night. The unit is well made in the USA and is 26 inches long and about 6 lbs in weight. The heating element is a metal rod running the length of the heater and no light bulbs are used . It does glow a little but nothing strong ( see photo ). One thing I don't like is the chains provided to hang the heater. They work but I would of liked to see a little beefier chains. The electrical cord is fairly long also so I didn't need to use a extension cord. I have the heater hung around 32 inches from the floor. I took some photos this afternoon when the outside temperature was 24 degrees. The outside temperature is from the wired probe I put under the heater and it also shows inside temperature of the coop. I really like this heater as a brooder or as a heater to raise the temperature a few degrees in a coop.
