Water heating / electric heating


The big difference between an infrared heater and a conventional convection-based heater is the way heat is distributed. While infrared heating heats everything except the air, the opposite happens with convection-based heating.

The radiator heats the air against it, which rises up to the ceiling, steadily decreases in temperature on its way to the opposite wall, causing it to sink to the floor and finally return to the radiator.

This causes air to circulate in the room, which heats the entire room air; this is called convection. However, this well-known and widely used system also has a number of disadvantages that are not known to the majority:



Heating the air also changes the humidity. The result is dry heating air in winter. The consequences are drying out of the skin and mucous membranes. The danger of colds increases.


To improve the efficiency of convection heating, radiators have an optimised design (with fins) to accelerate the air more and thus facilitate the creation of air circulation. A lot of dust is stirred up and distributed throughout the room - even in the air that is breathed in.


However, the air circulation not only not only dust is stirred up, but also the faeces of the dust mites living there is also dust mites are distributed in the room. This is why people with allergies have great problems, especially during the heating season.


Warm air can absorb more moisture than cold air. If you a cold bottle of water from the water from the refrigerator refrigerator in the summer, it will very short time, it will be covered with covered with drops of water. The reason for this is the condensation of the water vapour in the air: The water vapour always condenses at the coldest point in the room. In in winter, these are usually the windows and walls in a house.


The combination of warm air and humidity, for example on a wall, is the ideal basis for mould. Black mould spores are naturally contained in the air and are distributed throughout the room by the room. If the room is warm and the walls cold, they like to settle there and begin to thrive.


The rising warm air and the sinking cold air create an air stratification with different different temperature levels. This effect is colloquially known as known as "warm head and cold feet". and is perceived as uncomfortable.


A relatively large amount of effort is required to heat the air in a room (burning an energy source, heating water, transporting water to the radiator, etc.). For a pleasant indoor climate, however must be ventilated regularly, however and all the energy is lost in the process.


In winter, the sun is lower than in tilt of the earth, is lower than in summer, which means that it shines through windows windows and can heat up rooms. To avoid to avoid overheating, the radiator the radiator should be switched off. However, a radiator heats up for up to 30 minutes and needs about 10 minutes to 10 minutes when it is switched on again to to get up to temperature. This delayed reaction time is due to the fact that because water is a good heat accumulator but releases this heat only slowly. Due to this sluggish behaviour, during the heating season. large amounts of energy are wasted.


Such heating systems require annual maintenance in order to for example to replace clogged filters filters and a visit from the chimney sweep. Possible repairs caused by wear and tear wear and tear every few years every few years. Ultimately, annual maintenance costs.



The principle of electric underfloor heating is relatively simple to explain: a wire, similar to a water under the floor covering, similar to a water underfloor heating. When the current flows wire is extremely heated and thus warms up its environment. However, this heating method is inefficient, as the hot wire must first bring all the must first bring all the gaps up to temperature before a noticeable increase in temperature. This technique is also very energy intensive.


With this type of heating variant, storage media are heated with cheaper "night-time electricity" (low tariff electricity) and release their heat to the individual rooms, usually with the help of built-in fans. This heating method is also inefficient and uneconomical. Therefore, a ban on this is why a ban on this heating method is a recurring topic in politics.
