Once it was true that speed didn’t cause any change in energy saving, and still now, it costs you no change if you choose the wrong regulator. Then there was no option left for the consumers to use, but at present, there are more options for you to choose from.
First let us throw a simple description of the types of regulators:
1. Electric/Resistor Type Regulator:
The bulky one and the oldest one. Because of its huge size, it needs some ventilators to inhale and exhale. The regulator can be operated by heating up clockwise to gain speed and counterclockwise for deceleration.
But the acceleration and deceleration can make no change on your energy bill. This big one can only increase and decrease the flow of voltage to get connected to the fan. So, you should avoid it for energy saving.
2. Electronic Regulator:
Under this category, we find two subcategories like moveable and step type. These are the latest ones in the market. For energy-saving purposes, manufacturers are producing them on a large scale. Compared to the electric regulator, these regulators can save 30-50% energy at deceleration.
These are more convenient for users and are also risk-free. Users feel more comfortable using them. The bulky one is now out of our dish.
Therefore, choosing one of the electronic regulators would be better for you. These are safe to use and don’t occupy a large space. The most important thing is that these save energy.
