Electric boiler: why to make this choice?

Compared to the gas boiler, the electric boiler offers many advantages, including:

  • A low cost of purchase;
  • Simplicity of installation;
  • A device that does not pollute;
  • Is not subject to any maintenance obligation;
  • Offers a yield close to 100%.

Even today, choosing an electric boiler appears – wrongly – as an expensive choice because of energy considered too expensive. A wrong argument, because the long-term performance of a boiler is calculated on its cost of purchase, but also on its operating costs.

Over 10 years, the electric boiler appears as the smartest choice, with a much more advantageous performance than an appliance with oil, gas, and even a heat pump.
