Buyers Guide to the Radiant Heater [Reviews 2019]

Functionality of the radiant heater

The heat wave heating, also known as radiant heating, uses in contrast to conventional heating neither gas nor other fuels, but electricity. A further characteristic of heating is the form of heat distribution, which instead of air convection uses radiant heat, which is similar to the energy of the sun. Basically, it is a more direct form of heating, as it does not heat the air in the room, but objects and living beings in direct reach through the radiation.

Due to the direct heat radiation, the air in the room is heated at the same time, but is not used as a carrier, which increases the application possibilities many times over. The functionality also includes simple installation, as it does not require any real installation. Due to the use of electrical energy, the heat wave heating is operated via a socket or electrical cable and can therefore be connected without any knowledge of installation technology. Another variant is glass heating, which uses another system for heating. It uses a conductive metal foil, which is charged with the help of electricity and then warms up and releases this energy in the form of heat.

For whom and where are heat wave heaters suitable?
Radiant heating offers interesting possibilities for use, as it can be integrated into any building and neglects the disadvantages of typical heating systems. They are particularly attractive for allergy sufferers, as they do not heat the air due to direct heating and thus do not swirl up any microparticles that could get into the human respiratory tract. Thanks to the direct heating, it is particularly suitable as an additional heating system and is suitable for high rooms that are difficult to heat via central heating. Other areas of application include:

Garages, cellars and attics
Individual rooms that do not have heating
Balconies and terraces
These heaters are often used for rooms that do not have to be heated continuously, but should not remain too cool for the duration of the stay, such as the hobby room as an example. Since the full heat output is achieved within a few moments, they are best suited for such projects. If the heating is no longer needed, it can be switched off and no longer heats immediately.

Possible acquisition costs

The prices of a heat wave heating vary strongly, since three important criteria define the purchase price:

place of action
The device itself costs between 400 and 1,000 euros, a little more is also possible. With many devices, however, care must be taken to ensure that the lower this is, the performance does not correspond to expectations. Before you buy, you should take care to consult the reports about the respective model, as these show problems that are not noticeable before. The larger the room or building to be heated, the faster the cost increases, as radiant heaters are not installed as central heating systems and therefore more units have to be purchased. At the same time costs are saved by the missing installation. A further cost factor is the design, because more and more often these heatings are offered in artistic form, which can be brought into modern and singular housing mechanisms.

Required wattage
Glass heaters and heat wave heaters use a certain number of watts that define the possible heat of the device. In order to define the correct wattage, the size of the room and whether it is a bathroom must be known. One square metre should be supplied with about 50 – 60 watts, with 60 – 70 watts recommended, as not all rooms, for example in multi-family blocks, are sufficiently insulated. The higher the wattage, the safer option is chosen. Who wants to use it in the bath, should count against it with 70 to 100 Watts, since only so the desired well-being feeling temperature of humans can be achieved. Depending on the size of the room, you will find precise information to help you choose a model:

300 Watt: 4 – 7 m²
400 Watt: 6 – 12 m²
500 Watt: 8 – 14 m²
600 Watt: 10 – 16 m²
700 Watt: 12 – 18 m²
800 Watt: 13- 20 m²
900 Watt: 15- 22 m²
1,000 to 1,350 Watt: Rooms up to 30 m²

Electricity consumption

In general, it is not possible to obtain any real information about the electricity consumption of the heating system, since three factors are decisive for the price determination. Firstly, there are the individual rooms with their required wattage and the operating time in which the heating is used. Depending on the room, this varies from one hour to the whole day. These values are combined and charged with the electricity price. If, for example, only a living room with 850 Watt is heated eight hours a day at a price of 0.19 Euro, the daily consumption is 6.8 kWh, which corresponds to about 1.3 Euro per day and about 232 Euro per year. Depending on the infrastructure of the building, however, the values can change considerably. Who has a solid brickwork, not too low outside temperatures and a strong insulation, can count on lower costs, since the warmth is stored better.


The most striking feature of a heat wave heater is its simple use, since only one socket is required for installation and, depending on the position of the heater, some simple tools such as a drill are required. Since it is supplied with the necessary energy by electricity, it only needs to be switched on after installation and heats the room within a few moments. The heater should not be touched during operation, as it can reach 80°C. Especially children should be kept away from them. The desired output is simply set via the individual levers and the heat is oriented to the stage and the set wattage. The higher the wattage, the more energy is used and the warmer the heating.

Important performance and safety features of radiant heating
Who wants to change to a heat wave heating, should consider some performance characteristics with the selection. The most important characteristic here is the wattage, which is important for the selection of the heater. The voltage must be taken into account. 230 Volts are the typical value for Germany and no other should be used. In order to ensure safety during operation, some safety features, so-called degrees of protection, should be provided. These include IP 40, which stands for a connection via the plug, IP 65 for the fixed connection. Splash-proof heaters are provided with IP 24, while IP X0 stands for no water protection. In this way, consumers can determine the necessary protection classes before purchasing and thus find the right heater for the bathroom, for example.

Positive properties

Low acquisition costs
Modern design
Easy installation at no additional cost
Better indoor climate, suitable for allergy sufferers
No pipe system necessary
Consumes little space
Negative properties:
Not recommended for houses with poor insulation properties
The different variants
Thanks to modern technology, the infrared heater can be offered in a variety of designs that can be attractively integrated into your own ambience. Classic glass heating can be found in the form of a glass pane, which is usually matt white and therefore does not stand out on the wall. They are very thin and therefore hardly noticeable. This form is to be found today also as mirror heating, picture or even board. In addition to the possibilities of placing the heaters on the wall, there are solutions for the ceiling, which are equipped together with luminaires and thus allow heat and light in one. A special design is intended for room corners. These round heaters close empty corners and keep living spaces warm. Particularly high-quality heaters can have the forms of an armchair, into which humans can warm up similarly a Sauna. Parking heaters are a type that are elaborately designed and can be placed anywhere in the room without even resembling a heater.

When making a purchase, bear in mind

When selecting a suitable heating system, the necessary energy requirement should be calculated beforehand, i.e. how many watts are required in the room. At the same time, attention must be paid to the distribution of the radiators, as several radiators with low wattage, e.g. 2 x 400 watts, are advantageous at a high wattage. Too much power in one place can quickly become too hot. Furthermore, it is important to use high-quality models, otherwise there is a risk of fire due to poor manufacturing.

Reasons to decide for the purchase of a heat wave heater

They are space-saving and require no installation.
Heat wave heaters are decorative.
