It's designed for exactly that — the alloy steel body and IP24 splash-resistant rating handle humid greenhouse conditions, and the thermostat cycles the heat to hold your set level. In deep cold, use it as supplemental heat aimed at your benches. Will it keep a small greenhouse above freezing in winter? Is it safe around water splashes? It carries an IP24 splash-resistant rating, so humid greenhouse air and light splashes are within its design. It's still not for direct water spray, soaking, or outdoor rain exposure. Keep it raised off wet floors and unplug before moving it. Will it raise my electric bill a lot? Smart energy-saving core. When your preset comfort temperature is reached, the heater automatically turns off the heating elements to greatly cut continuous power usage. It delivers up to 30% less energy consumption in overall operation. Can I run it all day in the workshop? The thermostat cycling and overheat protection are designed for all-day duty in covered work areas. Keep it on a stable floor, clear of fabrics and sawdust piles. For unattended overnight use, follow standard space-heater practice. How many square feet does it cover? The 1500W setting warms spaces up to 160 square feet — a small greenhouse, grow tent, garage work zone, or workshop corner. In bigger areas, tilt the body to spot-heat your bench or seating.
