How to choose
Coverage is the maker's figure
Maker coverage differs across the three: the ROVSUN is rated for up to 200 square feet and the TMWINGS for 450 sq ft, while the Dumos suits medium-sized rooms. Match the maker figure to your room, since a 200 sq ft rating will not cover a room the maker rates at 450 sq ft.
Heat settings and controls
All three offer 1500W heating, and the TMWINGS and Dumos add 600W and 900W settings for lower output. Thermostats adjust on all three, while the ROVSUN and TMWINGS include remotes and the ROVSUN adds WiFi app control. Timers run 24 hours on the ROVSUN and TMWINGS, while the Dumos timer switches the unit on and off.
Moving, noise and placement
The ROVSUN rolls on four swivel wheels for moving between rooms. The Dumos rolls on four casters with a carry handle. The TMWINGS has an insulated handle. Fanless radiant heating keeps the TMWINGS and Dumos quiet, while the ROVSUN runs quietly for indoor use. Plug the Dumos directly into a wall outlet, and give any oil-filled radiator clear floor space away from walkways.
