Transparent radiator — Invisible heat, visible comfort

The HERGA transparent radiator brings together design, efficiency and well-being in a practically invisible solution. Thanks to non-luminous infrared technology, it gives direct heat to people and objects, creating a pleasant feeling of comfort from the very first moment without having to heat all the air in the room.

Installation is quick and simple: it can be hung or stuck to the wall without taking up any useful space. And its surface makes for safe, comfortable everyday use in any setting.

Fitted under a window, it helps reduce the feeling of cold coming from outside and helps lower the dampness of the walls, improving the overall comfort of the home. Available in white, black and wood finishes to blend perfectly with any decor. Available with a manual switch with WiFi, a digital thermostat or a WiFi thermostat. You choose the level of control and energy saving that best suits your way of life. The WiFi versions are controlled from your phone with the free Tuya or Smart Life app.

How many units do I need?

The single most important question. Here is the honest answer — and the reason why some people feel it "barely heats".

ModelOne unit coversSecond unit from
Transparent radiator 6 m² > 8 m²
Wall-mounted radiator 12 m² > 14 m²
Portable radiator 14 m²
16-18 m² with good insulation
> 18 m²

The second unit is not meant to be on all the time

It works like air conditioning: you switch it on when you need it. In a 14 m² bedroom we use a single unit for most of the winter, and only turn on the second one on the very cold days of January and February. That is where the saving comes from.

Even with both on, the total power is still very low compared with any other system. And this is where the misunderstanding comes from: someone who puts a single panel in 12 or 14 m² and expects it to heat like a boiler says it "barely heats". It is not that it heats little — it is that the back-up unit for the hard days is missing.

Do not guess it

Enter the m² of each room in the calculator and in one minute it tells you the model, how many units, the final price and the saving compared with gas and heat pumps. These are the numbers that never fail.

💡 How to use it wisely

Use it like air conditioning: switch on the one you need. With two units in the same room, one is enough for almost the whole winter and the second only goes on during the coldest days of January and February. That active use is what saves the most.

The first two or three days of use are the ones that dry out the damp and warm up walls and furniture. After that you feel more warmth while spending less.

Recycled cardboard and no paper

Our boxes are recycled cardboard, with no plastic coating and no glossy finish. New boxes are unprinted: printing a box uses ink, solvents and energy and makes the product dearer without giving you anything. For some models we are using up every last printed box we have in the warehouse before moving to unprinted recycled cardboard: throwing them away would be a waste.

And there is no paper inside. The instructions and the warranty are online, always at hand, and they never get lost. That saves paper and ink, and they are always up to date: if we improve something, we update them straight away.

Frequently asked questions

How many m² does one unit heat?

The transparent radiator covers 6 m² per unit, and up to 8 m² if the room is well insulated. For more area, fit two units. For comparison: the fixed wall unit covers 12 m² (14 m² well insulated) and the portable 14 m² (16-18 m² well insulated).

Do I have to keep both units on all the time?

No. You use it like air conditioning: you switch on the one you need. A single unit is fine for most of the winter, and the second one goes on during the coldest days of January and February. That active use is what saves the most.

Does it burn if I touch it?

No. The surface works at around 87 °C but stores no energy: it only gives off the heat it generates at that instant. You can touch it while hot without getting burnt. It is NON-luminous infrared, the opposite of a red-hot quartz tube, which works between 500 and 900 °C.

How long does it take to heat up?

Radiant heat is felt in SECONDS. The first two or three days of use are the ones that dry out the damp in the house and warm up walls and furniture. From then on you feel more heat while spending less: patience creates savings.

How much does it consume?

460 W per unit. One hour switched on uses at most 0.46 kWh. Use the calculator to see your yearly cost with the real m² of your home.

Does it dry the air or stir up dust?

No. It does not heat the air or move it: no fan, no noise, no draughts and no dust in suspension.

What warranty does it have, and can I return it?

10-year warranty and 90 days to return it if you are not satisfied. We make it ourselves in Spain and sell direct from the factory.
