I have bought 2 Rohnson R-019 TURBO.
- The difference of the thermostat open-close is 2 degrees from the ambient temperature.
- The fan does not automatically turn on and off when the heating turns on and off, so I always keep it off because it creates cold drafts most of the time.
- Each device produces a lot of heat equivalent to 4-5 water radiators, and the air they emit is quite warm-hot. Indeed, they can heat large spaces quickly.

- Attention!!!
It dries the atmosphere quite a bit, especially in the high setting of 2300. If you use a dehumidifier, you will need to limit its use and find a way to humidify the environment if necessary.

For those who cannot calculate how much they will pay for electricity, things are simple:
If you have it on the 2300 W setting and it turns on, for example, 8 hours a day (with the on-off function), you will consume 2.3 x 8 = 18.4 kWh
If the cost of electricity per kilowatt-hour is €0.11 (from the power company), you will pay 18.4 x 0.11 = €2 per day for the device.
If you have a cheaper electricity provider and the cost per kilowatt-hour is approximately €0.07, you will pay 18.4 x 0.07 = €1.3 per day. (Of course, if you exceed a certain limit, the rates will increase and you will receive an inflated bill).
In very cold weather (10 degrees outside or lower) to have an indoor temperature of 21-22 degrees, expect it to be on for at least 16 hours a day with the on-off function for a space of 25-30 square meters. These calculations assume moderate to good insulation in the house.

Tips:
- First option: Have it on the high setting of 2300W (especially in large spaces) so that it heats up the room quickly and turns off quickly (this way you have better energy efficiency and more warmth).
- Second option (ideal): You can have it permanently on the 1000W or 1300W setting, with the fan running and the thermostat set to 30+ degrees so that the heating never turns off. This way, a) it operates at lower wattage, b) it utilizes the extra heat generated by the forced air circulation, c) you maintain a stable temperature in the room. With the 1000W setting, if it operates for 24 hours, it will consume 24 kWh, for 12 hours it will consume 12 kWh, and so on.
- The thermostat functions more like a timer because it is on the device itself and cannot accurately measure the actual room temperature. The higher you set the temperature, the longer it stays on and the less it turns off.
- Time how long it stays on and off (usually it is set at a specific temperature and you only need to measure it 1-2 times) to have an idea of the approximate consumption.
- Place it in front of the largest external opening of the room (window, door, balcony door, etc.). It is better to keep the curtains closed, but be careful to keep a safe distance of at least 25 cm between the device and the curtains.
