Fits almost all radiators and convectors

Fitting a SpeedComfort is very easy thanks to the
magnetic sliders on the top. This makes them suitable for almost all radiators and convectors.

With standard radiators, simply click the SpeedComfort under the radiator straight from the packaging.

If you have a narrower radiator, pull the magnetic slides out of the housing and re-install them with the magnet facing up.

If you have a single radiator, pull the magnetic slides out of the housing and re-install all four with the magnet facing up on one side.

For a convector or convector pit, it works slightly differently. On the underside of the housing there are four legs. Place the legs in the holes designed for this purpose. Make sure the foot is in the longitudinal direction. You can fit the SpeedComfort both on or under the convector block.

How do SpeedComforts work?


Universally applicable

SpeedComforts are suitable for almost all radiators and convectors. Thanks to the magnetic sliders, it is possible to use them on almost all radiators. Use the legs in the housing to place them on the convector.


Automatic operation

SpeedComforts come with a thermostatic switch that clicks onto the radiator near the hot water supply. The SpeedComforts switch themselves on automatically when your radiator or convector gets warm. Once the temperature near to the switch reaches 33 degrees, the fans start automatically. At 25 degrees they switch off again.


Silent fan

SpeedComforts fans are extremely quiet. They make less than 20 db of noise. This is less than the sound of rustling leaves.


Lossless adapter

The included adapter is lossless. SpeedComforts are energy efficient: they use about €0.32 worth of electricity per year.


Can be installed in minutes

SpeedComforts can be fitted to most radiators and convectors. No tools or technical knowledge is required. The built-in magnetic sliders (see video) mean you can easily click the SpeedComfort under any radiator. Or set it up on a convector using the legs from the housing. These are included as standard. Then place the sensor (using the magnets) on the heater near the hot water supply and plug the adapter into the wall socket. You don’t need to do anything else: the smart radiator fan switches itself on and off at the correct temperature.

Together, we can reduce our CO2 emissions

Purchasing the smart radiator fan will help you save money on your energy consumption and get more comfort in your home or business. The SpeedComfort’s expected lifespan is 40 years, and you get a 10-year warranty on the product. This way we contribute together to a sustainable and just society.


We have collected some of our most frequently asked question below.

Installing a SpeedComfort is very easy thanks to the magnetic sliders on the top. A small adjustment is all that is required to make them suitable for most radiators or convectors and to install them. Then install the temperature sensor, also with magnets, on the radiator near the hot water supply (usually near the on/off knob). Then put the plug into the wall socket.

For radiators with two or three panels and at least 7 cm between the panels, install the SpeedComforts as they come out of the packaging using the magnetic sliders. The magnets will automatically “click” onto the iron of the radiator.

If the gap between the radiator panels is less than 7 cm, you can hang the SpeedComfort under the radiator. Pull the magnet sliders out of their track, rotate them so the magnet faces upwards and slide them back. The SpeedComfort can now be installed under the radiator.

The magnet sliders can also be turned round for a single panel radiator, but with all four magnets on one side.

Four feet that can be pressed into the special holes can be found at the bottom of the SpeedComfort. These can be used to install the SpeedComfort onto a convector or into a convector pit.

A SpeedComfort moves approximately 30 m³ of air per hour. All the air in a room should preferably circulate once per hour. 1 SpeedComfort is enough for a small (bed) room of about 12 square metres. More will be required for a bigger room.

Calculation example: a living room of 5 m wide, 8 m long and 3 m high has a capacity of 120 m³. In this case you need 4 SpeedComforts: a Trio set with an Extension set, or two Duo sets.

– Bear in mind that an average length of 50 cm is required to put a SpeedComfort in place. This means 3 SpeedComforts will fit on a radiator/convector measuring 1.60 m.

SpeedComforts switch on at a fixed temperature of 33 degrees. They switch off again when the radiator cools down to 25 degrees.

The noise level of a SpeedComfort is less than 20 dB(A). This is a noise level that is lower than rustling leaves.

Do you think the noise level is still annoying? Please don’t hesitate to contact us. An adapter with a slightly lower voltage is available. This means the fan rotates slightly slower, which produces less noise.

You can easily connect SpeedComforts using a connection cable. These cables are included as standard in the duosets and triosets, as well as in the extension set.

Please note that you need an average of 50 cm length per SpeedComfort for placement. So, on a radiator/convector of 1.60m, you can fit three of them. You can connect up to 20 SpeedComforts, using a single adapter.

In the webshop, in addition to the complete packages, you can also find Extension Sets. These always come with a 30cm connection cable. Cables of 60 and 120 centimeters are available for purchase separately on the website.
