Perfect winter heater without the dryness
This little heater surprised me in the best way. It kicks out great, steady heat and keeps the room cozy without drying out the air — a huge win in the winter when everything already feels like a desert. It’s quiet, simple to use, and does exactly what I need it to do.

Will this heater come back on after a Black Out???
The instructions are not clear if this heater can be set to come on every day at the same time but also it does not say if the heater will come on as programmed AFTER a power outage or blackout??? We want to know if
the heater will come back on by itself after a Power Outage or power interruption???

This is my favorite heater!
I’ve used lots of portable heaters in my 40 years, and this one is my favorite! I’ll be getting another one for my basement. It warms up quickly and puts off a good bit of heat without annoying noise or fans.

Makes Weird Noise
I bought it 2 years ago but the heater started making noise(tick tick tick tick ………..every 5 minutes that is very disturbing at night) even the same year. Not sure if it is a problem with the heater or it is how it is designed to work.

Liked it so much I bought a second one!
I purchased my second heater a few weeks ago to sit next to me when watching TV this winter. Even though the room is much larger than the bedroom where my first heater sits it does a great job keeping the area around my chair warm. I expect the second heater to work as perfectly as my first DeLonghi heater has...

Wonderful product
I got the DeLonghi Radient room heater at the best time! Our apartment wasn't fixing my heat properly and winter was keeping the apartment chilly! This kept the house warm without taking up too much space, it does pack some power, we had a breaker blow when another room had a space heater turned on but thats to be expected. Overall a great product and something I am gla...

Amazing
This heater is amazing. Warms up a small room very quickly. It has auto shut off if it gets bumped or tipped for any reason- awesome safety feature. Has plenary of temp settings to make sure the room stays comfortable. Highly recommend for a bedroom or bathroom.

Works great!
Quick assembly and hookup. This heater has the chill out of the room in minutes. Very easy to use and it’s quiet. This comes in handy on colder nights before bed to just warm up the room before bed. I definitely recommend this product!

Heats up quickly!
I absolutely love this DeLonghi Eco digital full room radiant heater. This heater heated up my master bedroom within five minutes of turning it on. I love that this heater saved me money on my energy bill! I also liked that the heat that was coming out wasn’t super hot it had a nice warmth to it. I would definitely recommend.

Gentle Heat
I love this heater for many reasons; safety, it throws a very gentle yet effective heat and it's been cost efficient and energy efficient. I am able to heat my entire tiny house with this in New England weather.

Very quiet & efficient!
We have wood pellet stove in our home - that being said, part of the house doesn’t get as much heat as we’d like. I use this in my bedroom - placed it in a corner… it is SO EFFICIENT & VERY QUIET!! I can sleep very comfortably and warm - I am very grateful for this. The look is very modern and sleek - I love it!

Love My New Super Quiet Room Heater
I love my new DeLonghi oil filled radiant heater. My favorite thing about it is that it is so quite. It literally does not make any noise at all. It is simple to use,..just plug it in, press the power button and adjust the temperature. Being able to set the delayed start or delayed stop option is a bonus.

Nice and quiet
We have used various other portable heaters in the past, but this Delonghi heater operates in a completely different way than we were accustomed to. It operates using an oil filled radiator that provides a gentle heating of the space, rather than a loud fan. This Delonghi Radia Eco Heater is so quiet we had to go over and make sure it was on since we couldn't hear a thi...

Great heater
We have very cold winters and we always like to have a few backup heaters just in case the power goes out. We have some colder areas of our home and this heater has worked great to keep those areas warm.
