ENSTO stands for:
The basic principle of operation of these heaters is natural / free / convection, in which the heated air from the heater rises upwards. The convector has two openings - at the bottom (from where it draws cold air) and at the top (from where the heated air exits). The lack of accelerated convection makes them very comfortable, in contrast to fan heaters, which create an artificial current in the room and cause health problems.
The heater is made of massive electrical resistance material with very low electricity consumption and virtually no risk of overheating. It is controlled by a built-in high-quality thermostat.
Electrical appliances made of high quality, which is why they have a long service life.
