A heat diffuser is just what it sounds like - a diffuser that uses warmth to evaporate essential oils. Generally speaking, models of this variety, like our eWarm Essential Oil Warmer, don't even use electricity; instead, they make use of a candle that heats a reservoir of oil from below. Though this makes heat diffusers a more economical choice than other varieties, that affordability comes at the cost of sacrificing control over the diffusion over the oil. Additionally, they're not appropriate for any areas in which open flames are not allowed.
