The Dr. Infrared Heater DR-218-3000W is a fan-forced electric heater built for damp greenhouse conditions. It requires a 240V, 20A circuit and delivers roughly twice the output of the 1500W model.\u003c\/p\u003e\n\u003cp dir=\"auto\" class=\"break-words last:mb-0 max-md:leading-[155%] max-md:mb-4 max-md:last:mb-0 streamdown-first-block:mt-0\"\u003e\u003cstrong class=\"font-semibold\"\u003eWhat the 3000W DR-218 does\u003c\/strong\u003e\u003cbr\u003eThis heater uses fan-forced air to move heat across plants, benches, and soil so they stay above freezing instead of turning into frozen, soggy mush.
