Electric Radiators, the fast solution for heating needs

Electric Radiators: what do you need to know?

Changing or adding to the heating plumbing system, in a house is always has the potential for a lot of building work to be needed; the installation of an electric product is a possible convenient option, because not having to create new pipe work connections makes an electric radiator the ideal product.


Electric radiators can be specially designed to meet the needs of homeowners who cannot, or do not want to, make big changes to their system.


The heating process within takes place thanks to an electric current connected to a safety thermostat; the energy from the electrical resistance is transformed into heat, and a special thermal liquid that fills the whole radiator is heated. The thermostat controls the electric current increasing the heat until the temperature set is reached.


There are different types of heating elements, with more or less advanced technologies: from simple on/off, to those regulated with thermostat, timers  and wi-fi control.


Electric radiators are often installed in the bathrooms, that may also have underfloor heating because of their additional practical application as towel warmers.


Electric radiators can be managed with a timer thermostat; this device allows to regulate the temperature in each room, regulating when the radiator is on and off, setting the timer and the desired time bands. You can then decide when you want to heat your rooms throughout the day, when you are at work for example, it is not important to keep the heating on, with a set program the timer thermostat can be programmed to turn the heating on before you get home and so save a lot of electricity and provide flexible control.


How to choose radiator wattage.

The power of the radiator must be calculated taking various aspects into account. The size of the room to be heated, the average temperature that you want to keep in the room, its position, and the type of house in which it is located. This are just some of the information needed to correctly estimate the output of any radiators. It is very important to correctly size the electric radiator to be installed to avoid not having enough heat and feeling cold.


In order to determine which radiator is best suited to the needs of each individual room, you need to calculate the watts required based on the following information:


    Room size (length/depth/height)

    Type of room (living area/ sleeping area/bathroom)

    Building insulation (poorly insulated / very insulated / Class A)

    Minimum outdoor temperature (-20° to +5°)

Dual Function Radiators: the ideal solution for mid-seasons.

As the name itself says, "Dual fuel radiators" are radiator or towel rails connected to the central heating system but which, thanks to an additional electrical heating element, can also operate electrically, which means that these radiators can also be used independently of the central heating system, offering greater control and flexibility.


This allows the radiator to be used even during periods when the heating system is off, in summer for example.  


In order to be able to use both in hydraulic and electric, without needing to modify the existing pipework, IRSAP proposes the use of special valves that allow the insertion of the electric element into the radiator, through the valve  (picture 1).


Range and offer of electrical products: how to choose?

The wide range of IRSAP electric radiators can provide a solution to wide range of heat output requirements (250 to 2000 Watt) and for every room the house (with various models and sizes).


Many electric radiators can be integrated with:


  • ON/OFF control

  • Electronic thermostat to regulate the temperature of the radiator

  • IR electronic control to regulate the ambient temperature and remote  control for electronic control

  • Wireless digital electronic control, programmable weekly to manage the operating times and bring the ambient temperature to the desired level. This wireless control also allows you to reach the temperature set at the desired time through the ITCS (Intelligence Temperature Control System) function by adjusting the radiator's early ignition according to the ambient temperature.



The IRSAP range offers products that range from design models, for those who are looking for contemporary modern designs, to the more classic bathroom, furniture, or multi-column models, versatile and functional suitable for heating and furnishing any domestic environment.


Everything you need to know about electric radiators and new regulations.


IRSAP has embarked on a programme of developing models in line with the new ECO DESIGN regulations, working towards product design in accordance with a responsible philosophy from many points of view: environmental first and foremost, but also ethical and social.


Providing the possibility to choose the most suitable product for your needs, respecting the environment and ensuring maximum energy saving. 


The latest generation of electric radiators must comply with current regulations on energy saving, and they allow a much more controllable and efficient level of comfort. Due to the new developments in temperature controllers including the ITCS (intelligent temperature control system) function.


The ECO DESIGN 2018 regulations make a distinction between towel warmers and electric radiators: towel warmers can operate with only have an on/off function; electric radiators must be able to manage set temperatures and time slots.
