I assume your room is kept at least at 70F or more. I fill up some buckets for my water change and set them near the tank (on a shelf underneath). I find that since I am only changing 20% of my tank water at a time this is close enough. Otherwise run the taps and mix wrm and cold water til it "feels" about right. Close is good enough.
I would do a change when the ammonia climbs over 1.0 and nitrites over 0.5. So do another water change tomorow or if you have the time first thing in the morning.
