Heater to go with my Ranco controller

[reaper7534]

Currently have two Jager 200w heaters on my controller for a 75g tank.

Just purchased a 180 and sump will hold approximately 15 gallons of water. So I'm figuring right under 200 gallons.
My ambient during the winter is around 68 and summer is around 75.

The Jagers are really long so I'm thinking of going with a couple of Titaniums from Jehmco. What wattage would you
recommend to keep my tank at around 85-83 ?

My sump is going to be two small to accommodate the Jagers and the titaniums seem to run smaller, once I figure out wattage
I will Jehmco for measurements.


Thanks

Tim,

I found this on the web which mostly agrees with what I have been taught.

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.

Thanks, the sump is approximately 35 gallons, I was guesstimating how my water will be in it.

((85°F-68°F)/10)*(3w to 5w)*200 gallon = 1000w-1700w. This doesn't take into account any insulative properties your setup may have, but 1000w should be your minimum. 2-3 smaller heaters are still better than 1 even with a controller.

Thanks, I will probably go for 3 400w heaters from Jehmco then.

I am going with a couple 500 watt heaters and will add a third if needed. Should I go with Finnex or Jehmco. If Jehmcho, are the bulkhead recommended ? Last thibg, can the Ranco handle 1500 watts if I find the need for it ?

Tim,

Most of the controllers I found were rated at 1000 watts or less. I would be worried that my controller would fail in the on position and fry my tank. I would buy a separate controller "10A 110V Digital LED Fahrenheit Temperature Controller Thermostat Temp Sensor" for each heater. I found them for less than $11 each (buy a couple extras for repairs). You will have to add a power cord and plug but that should be less than $10.

What do you think?

Ranco ETC 111000 handles up to 1500w, 1800w for the heavy duty version. These are as good as they come.
