Question about DeLonghi TRD0715T Oil Filled Radiator Heater

1 Answer

Won't heat I have an oil filled heater, my dog knocked my heater over and it fell on a sleeping bag. I didn't even know it fell, so it didn't fall on a hard floor. So i picked it up and turned it off and unplugged it. I tried to turn it back on and the lights come on, but now it won't heat. It has only been used for 1/2 a season, so it's almost new.

Check to see if the heating element has continuity or if it is even receiving power.

Oil Filled Radiator Heater Leaking

<p>A very common and increasing popular source of <b>supplemental heat</b> in the last few years has been the <b>oil filled electric radiator. </b> <br /> <p>These <b>radiator heaters</b> are filled with an oil that circulates through the fins of the heater and is heated by <b>electric heating elements</b>. The result is a steady even type of heat that has a lower surface temperature then many <b>space heaters</b>, making them a great way to get <b>supplement heating</b> into a room when you have pets, small children or combustibles near by.<br /> <p><br /> <br /> <p>One of the big questions that comes up with these <b>oil filled heaters</b> is what to do if they start to leak. The answer is that if the<b> oil heater</b> starts to leak then it is no good anymore and needs to be disposed of. These<b> heaters are filled with oil</b> at the factory and then are sealed tightly. Because of this there is no need to ever <b>refill the heater with oil</b> again. The heaters are sealed with the proper oil inside for the <b>best heating efficiency. </b> <br /> <p><br /> <br /> <p>So what this means is that if you have one of these <b>oil filled radiator heaters, </b>you will never have any <b>maintenance</b> or worries about <b>adding oil to the heater</b>. But if there ever is a leak then the heater is also no good and will need to be throw out and replaced. Very few of these <b>oil filled heat units</b> ever leak, but as is always the case there are always some that do.<br /> <p><br /> <br /> <p>A word of caution about heating efficiency. Always remember that when <b>heating with electricity</b>, the <b>laws of physics</b> always apply. <b>For every 1 KW of electric you will only ever get 3415 BTU's of heat.</b><br /> <p>There is no way to get any more or any less than that, so if anyone tries to tell you that their electric heater is more efficient then the next one they are not telling the truth.<br /> <p><br /> <br /> <p><br /> <br />

Won't heat my studio - even on "HIGH"

Does it get hot? If so, that is all you will get! It is not made to heat a room of 20 X 15 X 8 feet high. That is 2400 cubic feet of air space that may or may not be insulated. You need a quartz heater or two that are designed with fans to heat larger areas (see the specifications on them). The oil filled radiator is to put next to your rocking chair or under your desk near your feet!

My dog knocked something heavy onto my heater and broke two of the wheels. I need to know what material the wheels are made of (what type of plastic) so I can try to fix them. I think they can be glued...

ok well you shouldn't need any special material should be able to glue back or find four wheels that bolt to a tall toolbox which should be cheap at any hardware or lowes, homedepo store drill a hole where ever is not the oil tank, preferably where the tires use to be u know like where the old wheels useta be bolt down an good to go

I switch it on and with in ten mins its smokeing, whats the best way to get it fix it

Hey how's it goin'?

I had the same problem too.

There's a couple reasons the heater will do that, neither of them are good.

One reason is the heater has developed a leak and you can't fix that. The units are oil filled and if it was dropped or the dog chewed a hole in it ( I had a pretty mean dog ) then you can't seal it, it's time for it to go.

How the heater works;
Oil inside the unit heats up, expands and holds heat while you're getting warm. If the unit is leaking oil, you might even smell something like motor oil burning. That would be a gigantic tel-tale sign.

One other reason, and I had this problem too, is the wiring is getting tired and the wire jackets are getting too hot.

There's a couple reasons for that too, but unless you're a wiring expert or electrician, you're outta luck again.

Once the jackets of these heaters wiring starts to burn, there's no turning back. You need to replace all the wiring and terminals or solder new wiring inside. Special wiring, terminals the whole nine yards.

Rewiring one of these baby's is a job for an expert, even I might shy away from one. And I've been in the industry for 35 years.

The final question is this;
Is your dog's life worth saving $20 at a garage sale?
I know, I know, it can be a toss up.



Good luck.

Heater fell over while transporting in car,now it will not heat up even though the on lights come on to set power..

with heater unplugged, check all connections with an ohm meter, sounds like something got jarred loose. also check heating elements for resistance. if no ressistance, probably a broken heating element.

Oil baseboard heat v electric baseboard heat.

Two 8 ft baseboards will heat this basement fine. You should eliminate any sources of flooding before you invest in refinished your basement.

My heater won't turn on.

There really isn't anyway to give a difinitive answer to your problem. it requires some trouble shooting. Did you blow the breaker on the circuit feeding the outlet you had your heater plugged into? Is there a power indicator light on your heater? If so, when the dog tipped the heater over was it still working (ON)? If no indicator the problem gets more tedious and techy.

Oil heaters are great and simply designed. They are closed systems with heating elements that connect to the other end of the wire that plugs into your wall. The switch is in between the two to allow current to pass or not. If any of those connections was shaken loose by the fall it would cause your heater to malfunction. That's something you (or a service person) can only verify by opening the unit up. Hope this has helped...:-)
