Oil-filled radiators TRH 25 E / TRH 26 E
Mobile radiators with 11 fins and remote control – for cosy warmth with reheating effect.
The comfortable heating solution
Whether it's the unpleasantly cool transition season or icy winter – with the two oil-filled radiators TRH 25 E and TRH 26 E you can enjoy cosily warm feel-good temperatures.
It's your choice: black or white
The oil-filled radiators TRH 25 E and TRH 26 E are technically identical, however, their colour is different. The attractive all-black TRH 25 E is fully in line with the times and sets a stylish visual accent in your living or office environment. The TRH 26 E, in contrast, presents itself in classic elegant white – ideal for bathrooms or a light home decor. Irrespective of the colour: with 11 heating fins, 3 heating levels and a heating capacity of 2,500 watts, the two mobile oil-filled radiators already develop their maximum heat output after 8 minutes in rooms with a size of up to 30 m² or 75 m³. The convenient remote control as well as the 12h timer function provide for special comfort. The modern LED display adds a visual touch and clearly indicates the preset desired room temperature to you.
Perfect as additional heating, continuous heating or as frost monitor
With their 3-level adjustable heating capacity (1,000 W / 1,500 W / 2,500 W) the two mobile heating devices TRH 25 E and TRH 26 E supply thermostat-controlled temperatures in the range of 15 - 35 °C. The oil-filled radiators work absolutely noiselessly, odourlessly and without raising dust, therefore they are well-suited for the application in households of allergy sufferers or in the bedroom.
The mobile radiators are also suitable for heating rooms that are used irregularly like for example conservatories, guest rooms, garden houses, or also workshops and offices. In unheated garages and cellar rooms the radiators as frost monitors also provide reliable protection against frozen water pipes and further frost damage.
Good to know: Modern oil-filled radiators are still provided with the tried and tested heating fins, since this design ensures a maximum heating surface with an optimum heating capacity and effectiveness. The thermal oil used in the radiator is an excellent thermal energy reservoir, so that you can still enjoy a long lasting heat output even up to 30 minutes after the heating device has been switched off.
Thermostat-controlled feel-good temperatures
The room temperature should be always increased carefully. Because... overheating the room not only has a negative impact on the room climate – every degree too much also means approx. 6 percent of energy costs more. In a smart and power-saving fashion, the TRH 25 E and TRH 26 E provides for cosily warm room temperatures in the range from 15 °C to 35 °C. Set the desired target temperature easily and conveniently using the digital thermostat with real value entry on the device or use the remote control supplied, then the oil-filled radiator controls the heating capacity and the energy consumption fully automatically. When the desired temperature is reached, the heating device switches off automatically. When the temperature falls below the value that you have preset, the radiator switches on automatically again for reheating. This is not only convenient, the sensor-controlled temperature regulation additionally saves you a great deal of energy costs!
Precisely planned room temperatures: 12-hour timer
The 12-hour timer which can be programmed in steps of 1 hour is equally energy-saving and practical to adapt the switch-on and switch-off time of the oil-filled radiator to your individual daily routine. Whether it's still running after official hours in the office or at the end of an evening watching crime thrillers at home: You can always be sure that the heating device switches off after the preset operating time without having to spare a thought about it.
Stable safety benefits
Whether there are playing children, high-spirited pets or thoughtless guests in your house: The TRH 25 E or TRH 26 E is not easily thrown off its track. To make sure of this, it is provided with broadly designed low-friction rollers which ensure a secure stand of the device. In the unlikely event that the radiator does actually start to sway, an integrated tilt protection deactivates the device automatically. Additionally, a safety thermostat prevents the operating temperature from being exceeded, which for instance can happen if clothes are placed carelessly onto the heating device and cover it.
Can be applied flexibly in all rooms
With its smooth-running rollers and the integrated device handle the TRH 25 E or TRH 26 E is suited for the variable use in different rooms, even if it still hot. To prevent the power cable from becoming a dangerous trip hazard when moving the device to a different location, it comes with a convenient cable winder.
The two oil-filled radiators TRH 25 E / TRH 26 E convince by their attractive visual appearance, a long-lasting heating capacity and pleasant comfort – simply perfect for the temporary and continuous heating of smaller to medium-sized rooms.
This is how oil-filled radiators can supply warmth effectively
With their heating fins oil-filled radiators may look a lot like "normal" heaters – but quite contrary to them use electricity to heat the oil within. The so-called thermal oil is heated by electric current and gives off the heat to the room air via the heating fins. By the way, oil-filled radiators are usually equipped with heating fins because they form a larger surface, thus making the heating process very effective. Since the devices are mobile, they can be positioned in any room wherever heat is required.
The functional principle of an oil-filled radiator
Why is a radiator filled with oil and not with water? The reason for this is the fact that water expands when it is heated, and that it does not store heat quite as well. The thermal oil used in radiators, in contrast, has a much higher storage capacity. Even after the oil-filled radiator is switched off, it gives off heat for another good half an hour.
Since the thermal oil is also a good insulator, heating resistors can be directly immersed in the oil, which makes the heat exchange again more effective. Then there is also the weight, because oil is lighter than water. This makes oil-filled radiators considerably more light-weight and easy to transport.

Frost monitor function
Ideal for short-term property vacancies or temporarily used rooms
Using the stepless thermal control of our mobile oil-filled radiators you can also operate the devices in frost monitor operating mode. The heating device is then automatically activated by a thermostat to protect the rooms from frost and prevent excessive cooling. Functioning as frost guards, the oil-filled radiators are not only ideally suited for landlords and real estate companies – they also offer benefits for private and business people, who can thus keep vacant rooms and garages free from frost. Particularly rooms, conservatories or cellars which are not connected to a central heating system can be kept warm reliably in this way.
