Asking about heat is an excellent question. It's not so much the amp, but the room that needs cooling - for your personal comfort. A small room such as yours with a 9ft ceiling will warm up pretty quickly. (Have a T shirt and shorts on standby.) If you run your system frequently, expect your electric bills to climb upwards of $15-25/mo - not counting air conditioning. This is equivalent to a monthly subscription to Tidal.com.
I have two Class A amps - ss and tubes. In the summer, air conditioning is mandatory. Fortunately, my AC is fairly quiet - but it does create a constant white noise that can be distracting. It's not uncommon for people to buy a 2nd amp that runs cooler for just the summer months. OTOH, a Class A amp is a great space heater in the winter.
Where you live - what kind of climate - what kind of ventilation in the listening room - are all factors in dealing with a true Class A amp. There are many high quality Class A/B amps that don't generate as much heat. They put out Class A for the first several watts - which is fine for most listening.
