DeLonghi is a brand that won’t be as familiar to American consumers as Europeans, especially when it comes to heating and air. They are best known for their kitchen equipment and cappuccino makers in the states, although that’s changed in recent years with the launch of new products. For our DeLonghi space heater review, we are going to take a look at their heating systems, which span several different categories.

DeLonghi Radiator Space Heaters

DeLonghi TRD40615TManualAdjustable3YesNo
DeLonghi TRD50615EManualDigital3YesYes

While all of the systems from DeLonghi qualify as space heaters, there are a variety of highly-rated radiator heaters in their collection. They currently have six models available with a price point and set of features for everyone, including budget-conscious consumers that want something simple for their home.

DeLonghi TRH0715

With that in mind, the DeLonghi TRH0715 is the company’s entry-level radiator heater. That means it has manual controls instead of electronic switches, although the dial lets you choose between 700, 800, or 1,500 watts of heat. It’s a barebones unit without a tip-over switch, but it does have standard overheating protection.

The DeLonghi KH3901715CM is slightly more expensive but a far better option. It has tip-over protection to go along with a sleek, modern design and an economical mode. If you’re looking for a system with more features but that’s just as energy-efficient, the DeLonghi Radia S Eco TRRS0715E is an excellent choice.

This unit has a row of digital controls down the front of the radiator and a 12-hour timer. It also has a small digital display, just like the Radias ECO TRR2715EBK, a black variant of the heater. Our next two heaters have similar specifications as well, but there are a few significant differences between the DeLonghi TRD40615E and the DeLonghi TRD40615T.

The TRD40615E is the more high-tech of the two, with a small LED display and digital controls on the front. You can fine-tune the thermostat electronically, and it has a 24-hour programmable timer. Alternatively, the TRD40615T has manual controls and doesn’t have Eco Mode like most of the heaters in this series.

DeLonghi TRD40615T

DeLonghi’s flagship radiator heater is the DeLonghi Dragon4 Pro Digital Radiator Heater. It has electronic controls to go along with a digital dial that allows you to find the perfect temperature. A 24-hour timer and ECO Mode or included on this model, which is rated at 1,500 watts on high like the rest of the company’s radiant space heaters.

DeLonghi Convection Panel Heaters

Convection heaters aren’t quite as popular as fan-forced systems, but they are a great alternative for homeowners looking to upgrade from a radiator heater. These units are slimmer and typically have more features as well, including the ability to sit on the floor or be mounted on a wall.

DeLonghi HSX3315FTS

The DeLonghi HSX3315FTS has a unique style with an angled top and can be used directly on the floor or mounted. It’s a bit thicker than other models at 8.3” wide, but has three heat settings and is portable with a weight of only 14.5 pounds. The DeLonghi HSX3315FTS6A is essentially the same heater but without dual fans.

As with most of the heaters in DeLonghi’s collection, if you prefer electronic controls and digital displays to manual systems, those are an option. The DeLonghi HSX415E Digital Convection Heater has all of the features found on other models but is one of their newer heaters with electronic controls. While the DeLonghi HCD9115 has a similar design, it’s their thinnest heater and makes use of the company’s Hi-Fi technology.

DeLonghi Forced Air Ceramic Space Heaters

DeLonghi’s forced air heaters are available in several shapes and sizes, but all fall into one of two categories. Some are designed to heat up smaller areas and are considered personal heaters, while others are taller and fall under the tower heater classification. While both systems use ceramic heating elements, we’re going to cover the company’s smaller heater fans first.

Verticale Young Compact Fan Heater HVY1030BL

The Verticale Young Compact Fan Heater HVY1030BL isn’t the smallest unit from the company, but it is the most affordable. It has two settings with a thermostat dial and no bells & whistles aside from Fan Mode. A trendier heater from a style standpoint would be the Compact Capsule Heater HX30C15. The controls are set into one side of the handle on this portable unit, and it’s available in White or Gray.

Two other small systems are the DeLonghi Caldobango Bathroom Heaters. These units have the same basic design with manual controls and a GFCI plug, making them safe to use in damp environments like a bathroom. They also have a dial-based timer you can set for up to 24 hours, but the DeLonghi HVF3555TB oscillates while the DeLonghi HFS50D15 does not.

Having IP21 protection and the GFI plug is a bonus on those heaters, and they both fall under the company’s “Silent System” banner as well. This means they are designed to stay quiet while they keep you warm, just like the DeLonghi Silent Compact Digital Heater DCH5915ER. You can’t use this one in the bathroom, but it’s stylish enough to go in any other room of your home.

DeLonghi DCH5090ER

This is another one of the company’s newer heaters, so it has their Silence System and Eco Mode along with motorized oscillation. This 15” tall heater also comes with a remote control, which allows you to access the timer and other features. The DeLonghi DCH5090ER is an older variant of that model, but without the silence system and a slightly different design.

The second set of forced air ceramic heaters from DeLonghi come in tower form, and there are six models available, excluding older and discontinued stock. Again, most of these models have a lot in common when it comes to the design like the rest of the company’s heaters, although the TCH7690EDR has an older look and the affordable tag of the bunch.

DeLonghi TCH7915ER

This 27” tower fan has a small digital display with electronic push-button controls. It’s best suited for areas up to 150 square feet and three operating modes, including Eco Mode. The DeLonghi TCH7915ER is more or less the same system, but is newer, uses Silent System technology, and is slightly shorter at 24” tall.

The company gave a slight redesign to the DeLonghi HFX66V15C, although it largely has the same features and modes. Their sleekest model is the DeLonghi TCH8093ER, however, with a series of touch-sensitive controls and a clean, modern design. It has an advanced Eco Plus function like the TCH7915ER and a redesigned remote that matches the heater itself.

DeLonghi DCH7093ER

If you’re in the market for something a little shorter, but just as capable as the tower fans in this range, the DeLonghi DCH7093ER is well worth a look. At 13” tall, it technically belongs with the smaller systems we already covered; except for the fact it’s just a shorter version of the TCH8093ER without the stand or oscillation.

The premium unit in this category is the DeLonghi 3D Comfort Air Purifier and Heater HFX85W15C. As the name implies, this system can purify the air and doubles as a tower fan when it’s not heating a room. This 3-in-1 system has a unique design with 10 fan settings and six heat levels, but with a price tag in-line with Dyson’s heaters and less than stellar reviews.

DeLonghi Space Heater Warranties

Most of the heaters currently sold by DeLonghi come with a standard 1-year warranty except for the TRD0615E, DCH5915ER, and a handful of other newer heaters, which are listed at 3 years. While we would have liked to have seen a better guarantee from the company across the board, a 1-year guarantee isn’t uncommon.

DeLonghi doesn’t have any replacement parts listed on their website, but you can find parts through the DeLonghi Encompass site. A quick search turned up dozens of results, although we noticed a number of models had no parts listed or stock available. That can change at any time, but it is something to keep in mind if you aren’t partial to extended warranties plans.

DeLonghi Space Heater Reviews

You can buy heaters direct from DeLonghi or through a number of sites online. We were also able to find their products locally, so it’s not hard to get an honest opinion on the company’s heaters. With that in mind, we chose four models with excellent reviews that appeal to a wide range of homeowners.

DeLonghi Dragon4 Digital Portable Radiator

The Best DeLonghi Radiant Heater


Radiator heaters can be an acquired taste, especially if you need a heater for your living room or a busy area. While the DeLonghi TRD0615E still looks like a radiator-based heater, it’s one of the slicker models on the market today and full of high-tech features as well.

The DeLonghi Dragon4 has been completely redesigned compared to the company’s older systems. New thermal chimneys will provide maximum heat while keeping the surface temperature low. There is also an upgraded display with adjustable brightness to go along with a full complement of electronic controls.

You’ll also find several handy features on this heater, although it’s still rated at 1500 watts with standard modes. There is a lock button that ensures your settings stay put and a 24-hour programmable on/off timer. Eco Mode is an option, and this heater also has an anti-freeze feature that allows you to use it when the temperature drops below 33°F.


  • Good looking with a modern design
  • Electronic controls
  • Easy to use and maintain
  • 24-hour timer, thermal chimneys and lock button


  • lack of tip-over switch
  • Not loud but has a clicking noise from thermostat

DeLonghi Compact Ceramic Heater

The Best Compact DeLonghi Heater


While we’re big fans of high-powered heaters that can handle large areas, sometimes good things come in small packages. That’s the case with the DeLonghi DCH5915ER, which is the best compact heater from the company, in our opinion.

The DeLonghi DCH5915ER is in-line with the company’s new ceramic tower fans when it comes to the design – it’s just considerably shorter. Thankfully, it still has the same features found on their top-tier machines like a 24- hour timer, LCD display, and electronic controls. This heater is around 13.7” tall and rated at 1500 watts like the rest of DeLonghi’s space heaters.

Some fan-forced heaters can be noisy, but that won’t be a problem with the DCH5915ER. This little heater makes use of the company’s Silent System technology, which keeps things quiet while keeping you comfortable. It is also capable of side-to-side oscillation and sports one of the company’s longer warranties at 3 years.  


  • Compact ceramic fan with oscillation and multiple modes
  • Excellent array of features
  • Reasonable price tag
  • 3-year warranty


  • Nothing significant

DeLonghi 27” Digital Ceramic Tower Heater

The Best DeLonghi Tower Heater


When personal heaters don’t cut it, the next logical option is a tower heater. These units excel at distributing warm air throughout a room, and our favorite model from DeLonghi is the TCH8093ER Digital Ceramic Tower Heater.At 1500 watts with a height of 27”, this heater can maintain the temperature in a small to medium room with ease. It has two power levels, along with an upgraded version of Eco Mode called Eco-Plus. As it’s a fan-based system, you can also use the fan function in the summertime on the TCH8093ERSB to stay comfortable all year long.The design of this heater sets it apart from others in its class as well. There is a series of touch-sensitive controls on the front that rest below a discreet digital display. All the standard features you’d expect from DeLonghi are present on this flat panel heater with a 24-hour timer, oscillation, a digital thermostat, and a remote control.


  • Flat panel ceramic heater with plenty of power and Eco-Plus mode
  • Touch-sensitive controls
  • Motorized oscillation
  • A tip-over switch and a full-featured remote control


  • Some quality control issues

DeLonghi Convection Panel Heater

The Best DeLonghi Convection Heater


There aren’t as many convection heaters available on the market when compared to forced-air systems or ceramic heaters. These heaters can do something those other models can’t, however, and the DeLonghi HCX9115 is currently the top option from the company.This heater isn’t any more powerful than the company’s other 1500-watt systems but is designed to be used on the floor or hung on the wall with the feet removed. You can adjust this heater’s temperature through touch-sensitive buttons on the unit or put it into Eco mode for economical heating in a room.The HCX9115 is rated for rooms around 300 square feet and has three heat settings. Other features to note include an anti-freeze setting and a 24-hour programmable timer. It’s a bit safe than other heaters as well, thanks to the design and tip-over switch. Thermal cutoff is standard on this model as well, like the rest of the heaters from DeLonghi.


  • Dual fans
  • Can hang on the wall or use directly on the floor
  • Fully digital system with a 24-hour timer 
  • 3-year guarantee and mounting kit


  • No remote control
  • Pricey compared to similar convection heaters

DeLonghi Heater FAQ

Q: How do I shut off the alarm on my DeLonghi heater?

A: Certain models are equipped with an alarm that alerts you when the heater begins to overheat. If you hear this alert, unplug the unit immediately and check for any blockages. Do not plug the heater back in until it’s fully cooled down.

Q: Why does my DeLonghi heater keep shutting off?

A: This can happen for a couple of reasons, including when the thermostat kicks in and turns the heater off when the optimum temperature in a room has been reached. Eco mode and timers are two other reasons for your heater to cycle on or off unexpectedly.

Q: Is PTFE used in any of DeLonghi’s space heaters?

A: No. According to the company, their entire current lineup is PTFE-free.

Q: What’s the best way to reset my heater if a problem occurs?

A: The heater should be turned off and unplugged from the power outlet for 10 minutes. After that time, the unit can be plugged back in and should function properly.

Q: Why will my heater timer not keep accurate time?

A: While not a problem with digital timers, this can happen on models with dial-based systems that will reset if the heater has been unplugged.

Q: What type of oil does the DeLonghi radiator heater use, and how often should I change it?

A: All DeLonghi heaters use diathermic heat transfer fluid, although you never need to replace it or change the oil. All of these systems are sealed, and the oil is good for the lifetime of your heater.
