Reliable and Easy to Use

We have multiple DeLonghi oil heaters. This is our first digital model. It is reliable and easy to set. We purchased it as an upgrade for a large space (full finished basement) to heat more efficiently. It kept our dogs warm during a brutal cold spell and we felt safe leaving it on overnight for them. I do wish the unit's cord was longer, though. Of course, we don't want to use the heater with an extension cord and the standard length cord with RadiaS ECO Digital Full Room Radiant Heater limits where we can put the unit in the room.
I would recommend this to a friend!
