The DeLonghi TRH0715 oil-filled radiator is one of the least expensive radiant heaters the company makes, yet still offers that trademark beautiful styling and solid feeling construction that DeLonghi is famous for.

And, like all DeLonghi space heaters, the TRH0715 comes with a full 3 year manufacturer’s warranty! But is the DeLonghi TRH0715 oil-filled radiator heater a good space heater?

Let’s find out, by exploring the TRH0715 and how it works, talking about our own experience using the heater and looking at reactions from verified customers as well.

Is DeLonghi a Good Company?

DeLonghi (or De’Longhi) is best known for their beautiful espresso machines, coffee makers and coffee grinders and, well, all things coffee, and is considered one of the finest companies, and an obvious choice for top quality, for both homes and cafes around the world.

But DeLonghi also makes some of the finest products beyond coffee – if there is indeed a world beyond coffee – including kitchen appliances of all types, air conditioners, heaters, air purifiers and more.

If you’ve ever priced a DeLonghi espresso machine, you know that they are pretty darned expensive – and we would fully expect this for such superb and absolutely stunning products. And the same is true of many of their brilliantly styled and beautifully made home appliances.

That’s why we are so pleasantly surprised that the DeLonghi oil-filled radiator heaters are so reasonably priced – in fact, while not cheap, they’re competitively priced compared to other space heaters, and outright bargains considering how well they are built and how well they work.

What is an Oil-Filled Radiator Heater?

First invented and developed by DeLonghi, and now often imitated, an oil-filled radiator heater is a radiant heater, similar in many ways to any other radiator heater, but with an important basic difference in design which allows it to be very efficient and also to output a deeply warming and wonderful feeling heat, which somehow feels better than what you get from so many other radiant heaters. An oil-filled heater is different in that it’s, well, oil-filled.

It has a permanently sealed internal reservoir that extends throughout the heating fins and contains diathermic oil, which heats up with the heater and maintains that heat over long periods of time, only cooling down very slowly. T

his system holds heat so well that an oil-filled radiator heater can save lots of money on utility bills compared to even other radiant heaters – which are already known to be very, very energy efficient and real money-savers. Plus, oil-filled heaters still enjoy all of the main benefits of normal radiant heaters, including:

  • Uniform, Consistent Heating
  • Quiet Operation
  • No Maintenance
  • Less Expensive than many other types of heaters
  • Deep Heating and Comfort
  • Better Air Quality and No Allergens
  • Makes the Air Less Dry than many other types of heaters
  • And, again, Real Savings on Utility Bills!

Does DeLonghi make a Good Oil-Filled Radiator Heater?

So you must be wondering a couple of things:

  • Is the DeLonghi TRH0715 a Good Oil-Filled Radiator Heater?
  • Is the DeLonghi TRH0715 Worth the Money?

Well, if the DeLonghi TRH0715 is even a decent oil-filled heater we can answer the second question immediately with a resounding yes, because again, despite how expensive many of DeLonghi’s products for homes, coffee shops and restaurants are, DeLonghi radiator heaters are surprisingly inexpensive, and the TRH0715 in particular.

But the great news is that the DeLonghi TRH0715 is a good deal more than decent – it is, in fact, a well made, well designed and extremely effective oil-filled radiator heater, and a true DeLonghi product through and through –  again, not as cheap as some of the competitors, but nonetheless a premium product without the premium price.

What is Our Experience with the DeLonghi TRH0715 Oil-Filled Radiator Heater?

Since we’ve had experience with lots of oil-filled radiator heaters in the past, the first thing we did with the DeLonghi TRH0715 is to set it in our garage and run it for a full day out there, allowing the initial smell to burn off completely before using the heater in our house.

After that, we could never detect even the slightest odour when using the TRH0715 in any space big or small. Similarly, as we’ve used all types of radiator heaters quite a bit, we expected a bit of a ticking noise when the DeLonghi TRH0715 oil-filled radiator heater first started up, but while that sound was present it was much less than with other heaters we’ve used, no doubt because of the TRH7015’s excellent heavy-gauge metal construction, and was completely gone when the heater reached its operating temperature. And when it did, what great feeling heat it provided!

Even in a room larger than what DeLonghi specifies, the heat was so deep and satisfying, and – somewhat surprisingly for this design of heater – the whole room kept warm and comfy. For smaller spaces, the DeLonghi TRH0715 often needed to be turned down to the lower heat settings, but it was never overwhelmingly warm, but always felt just right.

In operation, the DeLonghi TRH0715 oil-filled radiator heater was simplicity itself, with only three high-quality, reliable mechanical controls to set temperature and heating level. The whole design of the DeLonghi TRH0715 was great, in fact, with nice, smooth castor wheels, a well-designed reel for the power cord and an overall look and feel that was attractive and appeared very high quality.

With absolutely no problems or issues, extremely effective heating, ease of use and good and attractive design, the DeLonghi TRH0715 oil-filled radiator heater was an absolute joy, and we recommend it highly.

What do Customers Say about the DeLonghi TRH0715 Oil-Filled Radiator Heater?

Customers seem to have very positive experiences with the DeLonghi TRH0715 oil-filled radiator heater, and Amazon customers alone have given it a nearly four and a half star rating even with over 1,400 separate reviews! One of the things most frequently mentioned is the feeling of the radiator’s deep, even heating.

While some customers complained that it takes a while for the heater to actually warm a space, they all pretty much agreed that once the room was warm it felt really wonderful, and stayed consistently warm over time. Lots of customers talk about having purchased one as a kind of supplemental or backup heater, to add to their furnace’s heating or to use if the furnace ever conks out, but they end up using the DeLonghi TRH0715 oil-filled radiator heater much more than they expected and used the furnace a lot less.

And so, as you might expect, many customers also beamed about the money they were saving! Customers love the way their DeLonghi TRH0715 looks, mentioning its nice styling and quality construction, and many also praised the extremely easy operation and the intelligent and useful design of the controls.

People mention that the DeLonghi TRH0715 oil-filled heater puts out no odour or fumes, and talk about how this compares so favourably with other types of heaters they’ve used or even other brands of oil-filled space heaters. In fact, customers are very impressed with several basic things about the DeLonghi TRH0715 and all Delonghi oil-filled space heaters, compared to other brands and types of heaters, including:

  • Quality look and feel
  • Quiet operation
  • Ease of use
  • Reliability
  • Clean air and odour-free heat
  • Big savings on utility bills, even compared to other space heaters
  • Beautiful design
  • Great Warranty and Customer Service

People tend to be fiercely loyal to DeLonghi as a company, and to their products, and the heaters are no exception. Indeed, we see more repeat customers for DeLonghi space heaters than maybe any other company’s – even more remarkable considering that customers tend to have them for many years!

Final Thoughts: Should You Buy a DeLonghi TRH0715 Oil-Filled Radiator Heater?

Any good radiant heater is a great idea these days – they help us stay warm as winter approaches, and as we are spending so much time at home recently they are especially important and nice to have.

A good space heater will also save us lots of money on utility bills since we can heat only one space or room in our home and can keep the furnace running at a much lower level.

There are actually less expensive oil-filled radiator heaters on the market today, and, of course, you can always spend more on one as well, but to get a real DeLonghi product at this low price point, and to get such a safe, clean running, effective heater that looks and feels so good makes the DeLonghi TRH0715 oil-filled radiator an easy choice.
