What is energy efficiency and why is it so important for heaters?

Last updated: November 24, 2025

Energy efficiency means much more than just environmental protection. For your company, it means the intelligent use of resources: The optimal ratio of energy supplied (input) to actual benefit (output), in accordance with EU Directive 2012/27/EU.

Alongside safety and durability, energy efficiency is the central goal of our product development at Neybo.

The Fallacy: Why High Wattages Are Often Misleading

Conventional heating systems are often designed according to the principle “more is better.” Many believe that a high wattage automatically means faster heating. However, practice shows: Poorly designed heaters with high power output lead to significantly higher electricity consumption and faster wear (especially on thermostats) without noticeably shortening the material’s heat-up time. The energy dissipates into the environment instead of reaching the material.

A Calculation Example: Efficiency Pays Off

Even with small consumers, costs add up. Let’s consider the following calculation example:

  • Electricity price: €0.40/kWh
  • Power: 100 W (0.1 kW)
  • Usage: 8 hours/day for 250 working days

The Calculation: €0.40/kWh × 0.1 kW × 8 h × 250 days = €80.00 electricity costs per year

Note: Inefficient devices with poor insulation often require double or triple the energy to achieve the same result, unnecessarily driving up your operating costs.

The Neybo Concept: How Our Heaters Save You Money

Our design approach starts exactly where energy is lost. We achieve maximum efficiency through six concrete features:

  1. Intelligent Insulation: Thanks to our special EPP housing, the heat stays where it belongs: on the container, not in the ambient air. This increases efficiency enormously.
  2. Low Thermal Mass: Our heaters are lightweight. We don’t waste energy heating up a heavy steel housing; instead, we direct the energy straight into your material.
  3. Perfect Fit: No air gaps, no energy loss. Cartridges and foil packs fit perfectly against the heating elements.
  4. Optimized Power Density: Exactly as much power as necessary to heat the material quickly without damaging it through “hotspots.”
  5. Uniform Heat Distribution: The surface area is heated evenly, improving the material’s heat absorption.
  6. Faster Heat-up Time: The combination of insulation and contact heat means the material is ready for use faster—with less power consumption.
