Types of air heaters

Types of air heaters

Air heaters are used both in residential buildings as well as in workplaces and wherever there is no possibility of using another heat source or where alternatives are sought – to achieve a better, safer and more cost-efficient heating than in the case of a traditional heating system. The heaters are classified according to the type of fuel. Oil, gas and electric air heaters can be distinguished. What are their advantages and disadvantages? Which one is the best?

Oil air heaters

They are the heaters that are most frequently used for heating closed rooms, production halls and are also used on construction sites in a portable version. The heaters can be supplied with diesel oil or heating oil. They are distinguished by their resistance to low temperatures and high durability. You can find oil air heaters with and without flue gas discharge. The first ones are additionally equipped with a heat exchanger that allows to obtain much cleaner heat. These heaters are used in places where people are staying, and ventilation is insufficient. Heating devices without flue gas discharge function are most often used in buildings to accelerate, for example, the concrete bonding process. However, it should be noted that this applies only to portable heating devices. The lack of a heat exchanger means that these devices produce flue gases that are harmful to health and the environment. They also do not have power regulation.


Gas air heaters

Instead of an oil air heater, you can choose gas air heaters; they provide cost-efficient use. However, these heaters can only be used in well-ventilated rooms, because one of the results of gas combustion is water vapour, and of course we should bear in mind carbon dioxide. There is also a risk of a leak in the pipe connecting the heater with the gas tank, so it should be ensured that a gas leakage protection is installed on the pipe. All this makes the gas air heater not a good solution when heating rooms in which people are staying. Lack of sufficient ventilation in the building, combined with a large amount of water that the device generates, contributes to the formation of mould and fungi. These are not good working and living conditions.


Electric air heaters

Until recently, electric air heaters were only selected for heating small spaces, such as kiosks. Today they have a much wider spectrum of applications and are also used on large surfaces. These heaters work very well at workplaces, in offices, shopping centres and even at home. Their greatest advantages are safety, comfort and ease of use, as well as great possibilities in the field of energy saving. Electric air heaters are supplied with electricity, they do not have an open source of fire, and a potential system failure is not a threat to people and rooms. Electric air heaters do not produce flue gases and are safe for health and the environment, which distinguishes them from oil heating systems. These heaters are suitable for continuous operation and, above all, have a wide range of applications. In contrast to oil heating systems, they can be installed in rooms with high humidity. These heaters work quietly and provide high comfort of use. It is also worth paying attention to the engine with which they are equipped. SonnEC electric air heaters have an EC engine with high energy efficiency. Modern control allows programming of heating according to individual needs. The user can plan the device operation schedule, which is important for heating costs.

Based on the analysis of all the advantages and disadvantages of different types of heating, it can be concluded that the best choice are electric air heaters equipped with an efficient engine and programmable operation mode. They are friendly to people and the environment and can be used in almost every building.
