Eheim verwarming heater - 300 Watt

I believe I have written a review for these previously. Fantastic item, very good quality materials and very capable. Example: you may have an inferior thermostat that was cheaper say, 300 watt to power a 300 - 400 litre aquarium when a 100 - 150 watt eheim item would do the same job. Therefore you're using alot more energy to do the same job which is more expensive in the long run and less consistent meaning you will have a higher degree of temperature fluctuations. This is an example, you can get the exact product specifications on the eheim website to size correctly.

After 30 years of fish keeping this the most accurate heater ive used great value for money
