No, you need a pump.

In my pond I dont have a heater and all my cichlids and pacu are fine, the main thing you need is a UV sterolizer...
Your cichlids will be fine, trust me

Are there any submersable heaters that are ok being outside?Dr Joe;1830222; said:Your going to need about 1400 watts of heater. I suggest multiple submersible heaters int the sump/filter.
The water heater is viable but tricky as they normally don't have a low enough setting and I would go with a 40g one, instant heaters are harder to compensate for as you need a holding/mixing tank for them.
