Description
Fully submersible, shatter proof and extremely reliable nutrient solution heaters from German manufacturers Eheim. Drop them, have them half in half out of the water and they will not break.
Features auto safety shut-off, accurate temperature control and a 1.7 metre power cable.
Probably the best suited tank heater on the market for hydroponic use, and great value for money as well.

How to use
Pick the size for the volume of your tank, from the list above. Set the temperature and put the heater in the nutrient solution. It is shatter-proof and will not break if dropped or left half in and half out of the water.
Aim for a solution temperature of 18 to 21°C. If your tank runs too warm instead, a Hailea water chiller cools it. See also pumps and aeration.
Questions
Which size heater do I need?
Go by your tank volume: 25W for 20 to 25 litres, up to 150W for 200 to 300 litres.
Is it safe if it comes out of the water?
It is shatter-proof and has an automatic safety shut-off, so it will not break if it ends up half in and half out of the water.
