I have the equipment in my chicken coop in the use and control so that an Elstein infrared radiators (100W at 6m2 floor space). If the temperature falls below a set value falls (with me 12 ° C), then the spotlight is turned on. But only in the set time (for me 20:00 bis 08:00 clock), if the barn is open during the day, is thus not heated. Toll drinking water and the chickens do not freeze. Works without disturbance.
