For the past 3 decades, I have replaced the heating system in my house with electric heaters. It is the cheapest way to heat with electricity, and under certain conditions, it can be the cheapest heating method.

The way a halogen heater works is as follows: a wire made of tungsten, several meters long (depending on the thickness of the wire used), is supplied with electricity at both ends, causing it to heat up. The repeated process of heating and cooling eventually causes the wire to break after a few hundred cycles. To extend the lifespan of the wire, it is coiled and placed inside a glass tube. Instead of using regular sand that would break after a few cycles, the tube is made of halogen, which is much more durable. However, if the halogen heater is accidentally hit while it is generating heat, there is a possibility that the wire will break immediately.

Conclusion: It doesn't matter if you spend 10 or 100€ on a heater... when the bulb burns out, it burns out.

For heating my house, I have 10 heaters that cost 10€ each, like the Esperanza, Mistral, and Conceptum models. I only use the top bulb, which is connected to a dimmer to reduce the consumption from 400 watts to 200 watts and prolong the lifespan of the bulb. The bathroom and kitchen each have one heater, while the two bedrooms, living room, and hallway have two heaters placed in opposite corners. When all of them are turned on together, they consume 2000 watts. From one end to the other, the house becomes warm (from 18°C to 24°C) in 20 minutes! In terms of energy efficiency (insulation), my house is neither the best nor the worst. If I keep them on for 24 hours, it will cost me 0.10€ x 48kWh = 4.80€, while the realistic daily cost does not exceed 1€ as they are in a controlled environment - a smart home that can be turned on before I arrive and automatically turn off based on different scenarios.

Why did I buy this heater:
1) It is easy to fix or replace compared to the other heaters I have.
2) It heats up the air more than objects like the floor or the body of the heater.
3) It has the option for better heat distribution by placing 3 low-speed, ultra-quiet 12cm fans underneath.
4) The purchase price is 9.72€ for 3x500=1500 watts, which is cheaper than the inferior ones I have.
5) The above reasons can help reduce my heaters from 10 to 6, saving space, outlets, and RF noise.
6) The replacement will be done gradually without any pressure, maintaining the balance between heating and cost.

5 stars for value for money and efficient operation.

P.S.: The heater may be labeled as Kumtel on the packaging. Whatever it says, it doesn't matter because they all come from the same factory, so they have the same quality and features.
