Help Me Choose a Heater

My Aqueon Preset 100W heater stopped working a couple weeks ago. Luckily, my weather is nice and my outdoor tub (~13G) and betta tank (5G) have enjoyed a nice temperature throughout the days without a heater. However, winter is coming up and the water in the tub and tank can get as low as 50F degrees. I’ve been looking for a good heater and one with the right wattage that will be able to keep my temps at around 78F degrees. My previous heater was only able to go up to 72F. I’ve been looking at these heaters on Amazon and was wondering what wattage do you guys recommend, especially in waters that can get cold.
I was thinking either 50W or 100W.

For around 13 gal, a 100 watt should do you fine. I definitely reccomend adjustable over preset. Don't kniw abkut the top link, but i do have an Orlushy in one of my 29s. So far has held steady over the first 2-3 months at 78. Have liked it enough i have a 2nd one to put in the other 29.

 

Depending on how long your last Aqueon lasted I would go with another one

It lasted 6 months. But I feel like it broke because of me. A silly mistake. Took it out of the water unplugged and started steaming.

Will probably get the orlushy one. It’s a bit smaller than the top link, around 4in smaller, which is nice.

 

for a 5 gallon, the marineland precision, 50 watt, for the 13 gallon tank. the 75 watt.
