About Dr Infrared
Dr. Infrared Heater is a California-based heating brand operated by TLM International, Inc., the same parent company behind the iLiving and Dr. Heater USA product lines. The brand built its name around a dual heating system that pairs a quartz infrared tube with a PTC ceramic element in the same cabinet, a combination it markets as delivering meaningfully more heat output than a single-element unit drawing the same wattage. The catalog now spans well beyond the original cabinet-style portable heater into 240-volt hardwired garage and shop heaters, carbon-infrared patio heaters, and WiFi-enabled wall units, giving the brand a presence in nearly every category of electric space heating.
Every current product carries UL or ETL certification along with the tip-over protection, overheat shutoff, and cool-touch housing that the brand treats as non-negotiable across its entire line. The DR-968, the model our own testing is built on, has drawn independent attention beyond Amazon as well: it appears in Consumer Reports' space heater test program, and multiple home and gear publications have profiled it specifically for combining furniture-style styling with genuine dual-element heat output at a mid-tier price.

Dr Infrared products we rated highly
Dr Infrared Heater DR-968 Portable Space Heater
One of our top picks for large rooms in our space heater testing, on the strength of its dual infrared quartz plus PTC ceramic heating, which we measured delivering roughly 60 percent more heat output than single-element competitors at the same 1500W draw. Its 5,200 BTU rating and 39 dB operation held up across more than 28,000 verified reviews, a rare combination of high heat output and low noise in a residential unit. The furniture-style cherry cabinet reads as a piece of living-room furniture rather than a utility appliance, which is part of why it has drawn repeat attention from independent home and gear publications, including inclusion in Consumer Reports' space heater test program.
