Betta fish heater

Its also winter here, do you think if i opened my window and let some cold air in that would help?

No, that won't help. It will simply cause the heater to spend more time being on. The water temperature will remain the same.

Does the topfin have a thermostat to keep temperature constant? My tetra thermostatically controlled 50 watt heater in my 5 gallon does not have to work hard to keep temp at a steady 78. It should be fine in your 2 gallon as well.

I dont really know the tempature of the room I would say 70 tops so to cold without a heater. I have an aqueon mini 10 watt heater, the other one is great has kept my tank at a steady 81, the only problem with returning it is i completely tore apart the package to get it out so i dont think they will take it back. The fish is doing great though, very happy and a LARGE bubble nest so I'm torn on what to do

I will be the lone voice of dissent here. From what you describe everything sounds OK. The bubble nest is a very good sign. I've always kept my Bettas warm and they do just fine.

Okay, update: I went to the pet store and all they had was the same Aqueon heaters (literally carried no other brand of heater) and got the same one but 5 watts since it's for smaller tanks. I´m going to install it today and hopefully, that one works better!

You should have brought back the bad heater and asked for a refund. Again, I recommend a heater that has a thermostat that is either adjustable or is set to keep temperature at around 78. They sell them on Amazon.
