Know that the TEM can be easily get from SLT, but as i know the price of the items there varies from bottom shop to upper floor shop. I personally get a relay with S$12, but when went up to top floor, its only cost S$8.
So, could anyone know which shop selling TEM with good price?
Hi wfc ,

Thanks.Your Qc for 20L thank is about 20.6W if you want to lower the tank temperature from 28C to 25C. If you are using any pump/filter just add the power rated for that pump to 27.47W. Example if you using ehiem liberty 100, rated at 3W , then your Qc is 20.6 + 3 = 23.6W.

Once your desired temperature is ahieved , you can turn off your TEM. After that your TEM "ON" time will depends on how well you insulate your tank.

I can't rememeber the shop i got my TEM from. But those in SLT are low power one. I got mine from ebay.

cheers
