Tank Size Heat 5ºC/9ºF Heat 10ºC/18ºF Heat 15ºC/27ºF
5 gal/25 L 25 watt 50 watt 75 watt
10 gal/50 L 50 watt 75 watt 75 watt
20 gal/75 L 50 watt 75 watt 150 watt
25 gal/100 L 75 watt 100 watt 200 watt
40 gal/150 L 100 watt 150 watt 300 watt
50 gal/200 L 150 watt 200 watt two 200 watt
65 gal/250 L 200 watt 250 watt two 250 watt
75 gal/300 L 250 watt 300 watt two 300 watt
Which would suggest approximately 800 watts should be plenty.
I believe 15 gallons for your sump is way too small, I would suggest at least a 40 gallon breeder tank should be the minimum; I know you did not ask about the sump size, but I did not charge for my opinion, ha.
