After a brief heat-up period the oil-filled radiators of the TRH‑E series create a quick and cosy warmth in your own four walls. The thermal oil used to fill the radiators has a high storage capacity, as a result they can continue to give off heat for quite a while after switch-off. Purchasing an oil-filled TRH‑E radiator is a worthwhile and affordable choice: if, for example, your central heating system fails all of a sudden, you will have a heating device immediately to hand and do not have to endure the cold.

Thanks to the reasonable acquisition costs the oil-filled radiators are suited for almost every kind of private application. Ideally, the devices are used as additional heating solution on cold winter days or for the temporary heating of garages or basements. Here they can also fulfil their function as frost monitor. Despite their powerful heating capacity the energy consumption remains agreeably low thanks to the thermostat-controlled automatic operation. 

The offered product range of the TRH‑E series comprises oil-filled radiators with various equipment features with or without an on-demand turbo blower, incl. a PTC heating element for faster initial heating. Owing to the integrated rollers and a carrying handle the radiators can be transported flexibly and safely between different operating sites even whilst hot. 

Even if they may look similar with their heating fins, oil-filled radiators – unlike "normal" heaters – use electricity to heat the oil inside them. The so-called thermal oil is heated by electric current and gives off the heat to the room air via the heating fins. This is why they are often referred to as "electric heaters". 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.

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 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. Oil-filled radiators are designed for continuous use since they can fully substitute a wall radiator.
