Setting up new 150 with 40 gallon sump.
Currently run just 1 300 watt heater on an inkbird controller for my 90. I’m in TX so it’s only truly cold for like MAYBE 2-3 wks out of the year. The inkbird does have an additional outlet. I’m I good with the single heater, or should I add another 300 watt.

I used to run one myself. Then I bought the ink bird with 2 heater plugs and temp sensors. now I run one in the main tank and one in the sump. It comes down to preference. I also don't run glass heaters but the titanium instead. I have had the glass ones break too many times.

I have a similar sized system and I run two 300 watt heaters for safety reasons. That way one is not doing all the work, in my mind that means it will be under less stress and less likely to fail. however always keep back ups and possibly a second temp controller or warning system. Heater failures are one of the most common causes of tank crashes.

I have two: a 500W in the sump and an 800W in the tank.

If you need 300W, then use 2x 150W heaters so both would need to fail at the same time to cook your tank.

My case is a little different, I use 2, but as I am in MI, and in the winter ambient in house is 58 degrees normally, I have 2 large heaters on a Helio so that if I only have one, I can maintain 78 with a 20 degree delta. If I lived where you do with such a small delta between ambient and tank, I would probably have one heater, as it sounds like in an outage your tank will not move far off your set temp, and you'd have plenty of time to get a replacement.

I am in Texas also and use 2 50 watt heaters on my 42 gallon tank with a 10 gallon sump. I have been doing it for 8 years and only replaced one of them about three years back. I run each on a different outlet on my controller. I also have the thermostats in the heater set 3 degrees above the controller settings as a backup off. The controller has power monitoring and it is set to send an alert if the power drops below 45 watts or above 45 watts on each outlet when the outlet is on. So if the heater cuts off for any reason I will get the wattage out of range alert. But you are right my heaters will start coming on late October and and stop in early april. Sometimes they are off for days even in the winter months. It does not normally take much to keep the temp at the setting as far as heaters since there is central air and heat in the house. My cooling fans run more than the heaters do.
