DeLonghi EW7707CM

- Good heat output for a small heater
- Practically silent operation
Cons:
- The plug could be better quality
The Final Verdict
The vertical tunnel heat with the DeLonghi TRD0715T was good because it meant the heater wasn’t as hot to touch. Nevertheless, today’s winner is the DeLonghi EW7707CM. It weighs less and although it has wheels, it still helps with transporting the heater. We liked the separate on/off switches but the most important feature for us is COMFORTEMP. This allows the heater to run pretty much automatically without any interference and no need for a timer. The extended warranty is another bonus.
