Energy is an important issue; therefore, thanks to use of state-of-the-art
technology, our Carbon Heater® heating systems convert almost 99% of the input
current into heat.
With an efficiency factor of 0,99, Carbon Heater®
waterbed heating systems are among the most efficient and energy-saving systems
available. This efficiency is achieved through the use of carbon as the heating
element. Additionally, both the digital and analogue control systems operate
with minimal power loss while offering optimum regulation. For example, the
water temperature is measured continuously and the heater only goes into
operation if and when the temperature falls below the set level.
The effects of electrical and magnetic fields are a subject of controversial debate. Therefore, to be on the safe side, Carbon Heater® heating systems are uncompromising in this regard, being provided with TÜV-tested (EMV and EMF) shielding technology.
