Aquael Comfort Zone Gold 200W

The principle of operation<br />
Traditionally, glass heaters, talking with some simplification, consist of a thermostat, contacts and coils of the heater. The thermostat controls the temperature of the water in the aquarium, and optionally closes or opens the contacts, and thus starts or stops the heating process of the spiral.<br />
<br />
The most sensitive element of this system is contacts over time due to metal oxidation, their surface is gradually contaminated.
