Question about DeLonghi TRD0715T Oil Filled Radiator Heater

3 Answers

Delonghi TRD715T Just got the new heater and it's making this constant rapid ticking sound.  I've seen reviews from Amazon that people have said it was silent, and I'm wondering if I have a defective one and do I need to return it.  I have the heater in the bedroom, so it's very noisy when we sleep at night.

    I get the rapid ticking noise too. (Though I probably don't have the same model heater that you have.) I think it comes from the TIMER. This noise is a real nuisance -- anybody know what could be done about it? Thanks,

    It's not the timer. It's the metal expanding against other parts. This is a sign of a poorly made product. I have had plenty of other electric oil heaters that made almost no sound... the only thing you could hear was the oil heating and it was very quiet. This is much louder and I intend to return it if I can.

It's 5:30 AM and I'm awake because of that ticking, popping, cracking sound. Every ten minutes the unit makes several pops rapidly, and it's quite loud.

It's almost definitely the metal. Some part of it is expanding or contracting with the temperature change.

Reviewers on Amazon who have attempted to return the product to Delonghi have been told they had to pay for shipping, which made shipping not worth it to them.

I'm experimenting to see if the sound comes from one side or the other (my unit has two radiator panels and you can turn them on and off independently), and it so far, with the left panel off and the right panel on, it has stopped popping, but that may be because the right side has not reached its shut off point yet.

If using just one side heats my bedroom without popping, I may keep it. Otherwise, I'm going to see if Amazon will accept return (before it's too late).

I don't believe it's anything most heaters will tick from the heat. Also it could be the timer even though my timer is quiet. but again it's better to call them rather then letting the house burn down. sorry to scare but it's the truth.

Does it sound like oil bubbles? Sometimes when an oil heater is heating up you can hear the pop sound of the oil heating.

Daily cost to operate

electric is billed at so many cents per kilowatt hour. a kilowatt hour is 1000 watts per hour. if your heater is rated at 3000 watts, running it for one hour will consume 3 kilowatts of energy at whatever your utility charges per kilowatt. if the amount on your bill is .026 per Kw it'll be 2.6 cents per hour.
