An electric convector heats the air inside the appliance. As the warmed air rises through the upper outlet, cooler room air flows into the heater and is heated in turn. This continuous natural circulation distributes warmth through the room without requiring an integrated fan on every model.

Convector heaters are therefore well suited to supplementary indoor heating where controlled room-air heating is required. How quickly the room reaches the desired temperature depends on the heater output as well as the room size, insulation, starting temperature and air exchange.

Heating output is one of the main criteria when choosing a convector, but the required capacity cannot be determined from floor area alone. Room volume, insulation, outside temperature, desired indoor temperature and heat loss all influence the actual requirement.

Use manufacturer room-size recommendations as orientation under the stated conditions rather than as a guarantee for every building. A poorly insulated room or a large temperature difference may require more heating capacity than a similarly sized, well-insulated room.

Many convectors distribute heat through natural convection without continuous fan operation. Selected models additionally use a turbo fan to accelerate the circulation of warm air when faster heat distribution is required.

A fan-assisted convector can therefore offer additional flexibility, but the fan also introduces operating noise. If quiet operation is a priority, for example in a bedroom or home office, check whether the model operates by natural convection alone or allows the fan to remain switched off.

A thermostat regulates heating according to the selected temperature or control setting. Once the target is reached, the heating element can switch off or reduce operation and restart when further heat is required.

Many convectors also provide selectable heating stages. These allow you to adapt the maximum heating output to the current requirement, while more advanced models may use electronic temperature control. Compare the control system rather than assuming that every TCH model offers the same number of stages or the same thermostat functions.

Additional controls can make a convector easier to integrate into regular room use. Depending on the model, available functions can include timers, remote controls, digital displays, window-open detection or app-based operation.

These functions are not standard across the complete category. Check which controls are integrated into the exact heater and whether a separate accessory, mobile device or network connection is required for the function you intend to use.

Portable convectors can be moved between suitable rooms and are useful when supplementary heat is required in different locations. Selected models are also approved for wall mounting, providing a fixed and space-saving installation.

Do not assume that every portable convector can also be mounted on a wall. Check the permitted installation method, required clearances and supplied mounting components for the exact model before installation.

Selected convectors offer a frost protection function that activates the heater when the temperature falls to the model-specific control threshold. This can be useful in suitable enclosed spaces that are not heated continuously.

Frost protection should not be treated as a guarantee that every part of a building, pipe system or stored item will remain above freezing. The result depends on heater capacity, room conditions, insulation, outside temperature and the correct positioning and operation of the appliance.

Some convectors are designed for use in suitable bathroom environments, but bathroom suitability must always be checked for the exact model. The protection rating, installation position and specified distances from bathtubs, showers and other water sources determine where the appliance may be used.

Do not infer wet-room approval from thermostat control, overheating protection or wall-mounting capability alone. Follow the operating instructions and applicable electrical installation requirements for the intended location.

An electric convector converts electrical energy into heat while its heating element is active. Thermostat control can reduce the amount of time the element operates once the selected room temperature has been reached, but this should not be presented as a guaranteed percentage saving.

Compare the required heating output, expected operating time and control functions instead of relying on general claims such as energy-saving, environmentally friendly or lowest-cost heating. Actual electricity costs depend on the appliance, room conditions, usage pattern and electricity tariff.

Start with the room and heating task, then compare the technical characteristics and operating functions of the available convectors.

• Match the heating output and stated room-size guidance to the actual room conditions;
• Compare the number of heating stages and the type of thermostat control;
• Check whether the model uses natural convection only or also provides a turbo fan for faster air circulation;
• Consider fan noise where the heater will be used in bedrooms, home offices or other quiet spaces;
• Compare timer, remote-control, display and app functions only where they are provided by the specific model;
• Verify whether the heater is intended for portable use, wall mounting or both;
• Treat frost protection as a model-specific control function rather than a general guarantee against freezing;
• Check the protection rating and installation requirements before using a convector in a bathroom or another moisture-exposed location.
