Oil-filled radiator TRH 28 E
Energy-efficient heating with convenience: 2,500 watt power with thermostat control, three heating levels, 24-hour timer and LED touch display
Quick warmth that lasts longer
The stylish TRH 28 E oil-filled radiator combines modern design and intuitive operation with the demands of an energy-saving heating system to heat rooms quickly and to the exact degree – to a pre-settable desired temperature in the temperature range of 16 °C to 30 °C. Whether you wish to heat a living room or bedroom, hobby room, attic, basement, workshop, garage or a holiday home – the 11-fin radiator powered by electricity already gives off its maximum thermal capacity after a heat-up period of only 8 minutes and in this way pretty quickly provides for cosily warm temperatures in rooms with a size up to 30 m² or 75 m³.
Feel-good warmth to lean on
The effective heating fin design of the TRH 28 E with its differently warm and precisely arranged heating circuits allows for a more even and more efficient heat distribution compared to conventional radiators, without making any compromise where the heating capacity is concerned. The maximum thermal heat is mainly emitted via die inside heating surfaces, while the outer edges at the sides show a lower surface temperature and can be touched – for example to shift the heating device whilst it is heating, carrying it by its practical recessed handle, or simply to touch the device to enjoy its pleasant warmth.
Energy-saving reheating effect
Good to know: Radiators of the TRH-E series are 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 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. This saves expensive energy costs and makes the use of the mobile heater even more economical.
Automatic heating unit with temperature preselection keeps heating costs under control
The energy-efficient way to enjoy cosy and warm temperatures: The TRH 28 E regulates the preset heating capacity and the energy consumption fully automatically with its intelligent automatic heating function. Simply preselect the desired target temperature (16 to 30 °C) via the user-friendly LED display – the thermostat control of the TRH 28 E will deal with the temperature control. Once the desired temperature is reached, the oil-filled radiator switches off automatically. If the room temperature falls below the value preselected, the radiator is switched on again automatically and heats on the heating level previously set. In this way, the room temperature always remains at a constantly pleasant level, the room will never be overheated, and unnecessary energy costs won’t burn through your cash.
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.
Comfort and safety for the whole family
Especially in households with children or pets, the safety of mobile heaters plays a crucial role. Maximum operating safety of the oil radiators of the TRH-E series is part of the basic design principle!
Safety due to tilt protection switch and overheating protection
Whether there are children playing, pets romping around, or careless guests – the TRH 28 E is not easily thrown off its track. Stable feet with low-friction rollers ensure a secure stand combined with a maximum freedom of movement.
If the radiator starts to sway by external influences nevertheless, an integrated safety tilt protection sensor switches off the heating device automatically. In addition, a safety thermostat prevents the device from exceeding the operating temperature and thus makes sure that the device does not overheat – for example, due to clothing placed on the radiator. In these situations, too, the overheating protection immediately switches off the device.
Convenient 24-hour timer
The programmable 24-hour timer with automatic switch-off is a particularly convenient way to help you save power. When you go to bed, simply set the desired operating time of the radiator (1 to 24 hours). The heating device switches off automatically after the preset time.
Mobile heat generation for all rooms
Smooth-running rollers allow for a quick and flexible change of location. Thanks to its innovative heating fin design and the recessed handles, the TRH 28 E can be taken from one room to another conveniently and safely even while it’ still doing its job heating.
Uncomplicated warmth with reheating and saving effect. The easy-to-handle oil-filled radiator TRH 28 E with digital LED touch display is to be recommended as an economical heat source for unheated rooms, as a quick-response heater outside the heating season and as an additional heater during the cold seasons of autumn and winter.

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.
Comparison TRH 27 E and TRH 28 E: Similar on the outside, technically slightly different
Both oil-filled radiators TRH 27 E and TRH 28 E are almost identical in appearance. However, there are technical differences. While the TRH 27 E has a stepless rotary switch for temperature adjustment, the TRH 28 E can be operated via LED touch display. In addition, the TRH 28 E comes with a timer function.
