It's a bit chilly here today, and I need to do a water change. The water coming from the hose is really cold, anybody know what I should do to make the experience, a little more comfortable for my fish?
 
I find that if you SLOWLY fill the tank back up, it will only change the temperature by a few degrees, but it will take a very long time depending on how many gallons you change. I change about 35-40 gallons and it takes about an hour and a half to re-fill it. Sometimes I'll get hot water and mix it too.
 
Too be honest...I haven't had a problem with that. I did it all last winter and no fish loss. I just started doing the slow method because I'd figured it was probably better and I got tired of boiling water.
 
If its really cold instead of adding slowly get a couple buckets use hot and let the air cool it outside. It is still adding slowly and will take long but seems to be less risky?
 
During cold weather I have the same problem. I fill my tanks back up with the water hose and it comes out very cold. My 156 gallon tank will require two buckets of hot water and my 265 takes four buckets of hot water to keep the temp around 80 degrees. Just make sure you don't just dump in all the hot water at once. I let the tank fill up a little, add half a bucket, fill some more, add hot water and keep doing that until full. That way the water stays right around 80 the whole time.

In the summer around July and August, the water comes out of the hose about 83-84 and is a little too warm lol but that's ok, never had a problem.

Does pouring hot water in create any bad gasses or anything?

Quickest way to kill an entire tank of fish, and I learned that the hard way. Hot water has much less oxygen, and will cause embolisms in your fish, believe me. Slowly warm the water with an aquarium heater, overnight if you have to.
