What is energy efficiency and why is it so important?

Energy efficiency means the rational use of energy. It corresponds to the ratio of energy supplied (input) to energy yield (output) as defined in the Energy Efficiency Directive 2012/27/EU.

In addition to safety and durability, we have defined energy efficiency as the most important goal of our product development. At a cost of €0.40/kWh and a continuous output of 100 W and an average of 250 working days, you get the following result:

0.40 €/kWh x 0.1 kW x 8 h/day x 250 working days = 80 € electricity costs/year

Conventional heating systems are often designed according to the principle “a lot (power) helps a lot”. In practice, however, this leads to much higher energy consumption and faster wear (especially of the switching elements of the thermostats/controllers), without noticeably accelerating heating up.

Our design approach follows these energy-efficient product features:

• an optimal power density (not too much and not too little)

• a homogeneous surface distribution of the heating output

• a better fit that allows better heat transfer

• better insulation, which leads to better efficiency

• a lower weight, which means that the heater itself stores less heat energy

• a faster heating time
