Thermal Fluid tech
The fluid used in our radiators is an exclusive high-thermal-transfer mineral oil. It provides stable comfort with fast heating times, and a lower surface temperature that extends the product’s lifespan due to more uniform heat distribution. This translates into more balanced energy dissipation and lower consumption.
Rointe oil-filled radiators include up to 25% more fluid than other radiators on the market, making them the perfect choice for efficient heating.
The heating element of these radiators is made of armored steel. Located at the bottom of the radiator, it converts electrical energy into heat, which warms the fluid in the most efficient and uniform manner. Next, the heated fluid can circulate through the radiator easily and quickly, heating the air that moves through the radiator and creating a natural convection cycle.

Touch-safe radiators
Our radiators have lower surface temperatures. Thanks to the balance between the resistance, fluid, and aluminum, the surface temperature of the product, once the set program is reached, does not exceed 43ºC. Additionally, the temperature is evenly distributed across the entire surface.
In other types of radiators, temperature gradients can occur between different parts of the product. This causes uneven heating and surface temperature, with the consequent risk of burns in extreme cases.

To ensure maximum energy efficiency, it is essential to select the correct size for your heating product. This means that not all models or sizes are suitable for every room in your home or property.
Frequently asked questions: Electric radiators
Are electric radiators efficient?
Electric radiators stand out for their extraordinary efficiency, as they convert 99.9% of the energy consumed into heat. Unlike central heating systems, which lose part of the heat through the pipes, electric radiators deliver heat directly to the room environment.
What are electric radiators filled with?
Electric radiators, such as Rointe brand radiators, are filled with Thermal Fluid Tech, a high-efficiency heat transfer fluid. This liquid allows better heat distribution and retention, ensuring optimum performance and uniform heating over the entire radiator surface.
Are wall-mounted electric radiators good?
The wall-mounted electric radiators are compact and feature a sophisticated design, perfect for small spaces or modern decorations. They are easy to install and provide uniform and constant heating.
Is it safe to leave electric radiators on overnight?
Yes, without a doubt. Our radiators can operate autonomously and unattended both day and night, as they monitor the ambient temperature and stop heating when it is not necessary. However, certain precautions should be taken in this regard.
- Avoid obstructions: Do not place clothing, towels or other objects on the radiator while it is in use, as this could cause overheating and permanently damage the radiator electronics or structural elements of the radiator.
- Safety distance: It is advisable to maintain a free space of at least one meter around the radiator. The obstruction of the air flow not only decreases the efficiency of the radiator, but also promotes overheating and possible damage to the radiator.
What warranty do electric radiators offer and how can I make a claim?
- 10-year warranty on the radiator body.
- 3 years warranty on electronic components.
