    Economically warms the house before I get up
    [This review was collected as part of a promotion.] Oil heaters are economical to run and take the coldness out of the air without drying the air which can dry your skin. Lovely gentle warmth and with the timer function the house is nice a warm when you get up on these chilly mornings.

    Great value and heating capacity
    [This review was collected as part of a promotion.] I bought this heater two months ago and it’s so warm! It’s ideal for large rooms too! In our bedroom we have it on low.

    Questions & answers

    Hi . Was wondering out of this model and the Delonghi Dragon4 Electric Oil Column Heater TRD41500ET which is more energy efficient . Cheers . Jonno · 2024-04-22
    Hi Jonno, the Delonghi Dragon4 Electric Oil Column Heater TRD41500ET is the more energy efficient of the two (using 1500W as opposed to 2400W), but the DeLonghi Radia TRRS1224T 2400W Oil Column Heater with Timer is approximately 35 percent more powerful.
