I received depressing news from the company that supplies fuel oil for my house. The price they charge has doubled since last year, and although I knew the cost of oil was rising, this increase far surpassed my expectations.
My solution was to adjust the furnace’s thermostat a little lower and use an electric heater to add warmth to whatever room I was presently occupying.
Since then, I have searched for a lightweight, portable heater that worked quickly and economically. Today, I am examining an oscillating ceramic heater that, according to its manufacturer, can easily handle these requirements.
This 24-inch-high heater is composed primarily of dark and light gray colored plastic and includes a front-mounted metal grill. It sits atop an eight-inch circular plastic mount.
A control panel perches above the grill. Typically, however, the accompanying remote is used to operate this heater.
Controls allow the selection of the desired temperature and mode, setting a timer, and increasing the area covered by oscillating the heater. The available modes include 700W, 900W, 1500W, and economy. In the latter mode, the device will automatically choose the output best suited for reaching and holding the desired temperature.
The Dreo Solaris Max’s fan blows air across a set of aluminum fins that have been heated by the device’s thermal-efficient PTC ceramic element. The heated air then passes through the device’s grill and warms the room.

PTC Ceramic Heating
The Dreo Solaris Max generates warmth using a PTC (Positive Temperature Coefficient) heating element. Ceramic heaters are generally used to heat a small room or office.
PTC heaters are self-regulating. While traditional fixed-resistance heaters employ wires and coils to generate warmth, PTC heaters use conductive ink printed on thin, flexible polymer-based substrates.
These devices take advantage of materials that increase their resistance as temperature rises. Simply put, less current passes through the ceramic element as it becomes warmer. PTC heaters draw full power initially, quickly heating up until they reach their optimum temperature. As the element heats, power consumption drops.
Air blowing across the aluminum fins warmed by the ceramic element effectively distributes this heat
PTC ceramic heaters are economical to run compared to traditional electric models. Oil-filled heaters consume even less power but are bulky and take longer to produce heat.
Space heaters can be used to quickly heat a small room or office while lower temperatures are maintained throughout the remainder of the home. They are also light enough to be easily carried from room to room.
Because it is self-regulating, this device does not run as hot as a traditional electric heater. The Dreo Solaris Max is equipped with overheating protection and an interlock switch that turns the unit off if it is tipped over.
I tested this device’s stability by bumping into it a few times, and while it took a bit of force, it could be knocked over. As soon as the heater fell, it emitted an indignant beep and turned its heating element off. The fan continued operating, cooling the element for a further 30 seconds. Then it shut down.
The rated noise level of this device is 37.5db. The sound generated by this heater’s fan was barely noticeable.
I used the remote to turn the heater on, setting it to 70 degrees in ECO mode. The fan began to turn, and a warm breeze immediately wafted from the device.
I jacked the requested temperature up to 71 degrees. At this point, the heater’s internal thermostat noted a more significant difference between the requested and actual temperature than the 700W setting could accommodate. The heater changed its output to either 900W or 1500W. The heat emitted by the Solaris Max significantly increased in temperature.
The next step was to select oscillation. Then slowly and quietly, the fan rotated within a 70-degree arc.
To keep operating costs low, Dreo equipped this device with the ability to operate, drawing 700, 900, or 1500 watts of power. The heater will choose the appropriate setting for the requested temperature in ECO mode.
Noise levels are good. I only noticed fan noise when the heater was first started or turned off. When oscillating, I could detect no sound at all.
The DREO Solaris Max produces heat as soon as it is turned on, quickly warming a small room. This heater is recommenced.
