This is a great space heater and its affordability adds to its fantastic value but with one caveat. It generates a disruptive beeping each time the heater adjusts the indoor temps.

The DeLonghi TRD40615E is a radiant heater that promises “1500 watts of heating power and silent operation.” This slim space heater is perfect for larger rooms that need constant heat especially during the winter season. This heater features patented steel construction and permanently sealed oil reservoir to prevent constant refilling. The brand claims that the TRD40615E can produce 40% of surface heat. It also features thermal chimneys to maximize heat flow while still being cool to the touch.

We liked the digital controls, adjustable thermostat and multiple heat settings because of the level of control the TRD40615E gives to users. We especially loved its ECO setting because the device adjusted the heat automatically without doing a number on our budget. Other features worth noting are the thermal cut-off and anti-freeze setting to prevent the internal pipes from freezing. The snap wheels are also a welcome addition especially for room-to-room use.

Using the TRD40615E, it truly is a capable machine able to warm up medium to large room quickly. Our only gripe is the noisy beeping when it adjusts the temperature. Unfortunately, since it adjusts the temp automatically, there’s no way to mute the audible beeping. As such, this is not ideal for use in the nursery or bedroom.
