Heating isn't really a problem, as there's enough heat from just about every operational system aboard that's turned on. The engineering spaces alone can reach above 120° F if the ventilation and AC is off.
Every major system, from the engineering systems, all electronic systems, even the galley ovens and stoves generate heat. The real problem is keeping everything cool, and for that reason the boats are cooled by huge AC systems and fans that run throughout the ship.
During a casualty drill, the fans are turned off (e.g., to deny the spread of smoke or contaminants from a fire), and you find out very quickly just how much heat is being produced by all the onboard systems.
The only real spot in the ocean where it gets a bit chilly is in the Arctic, where the water temperature is a constant 28° F. But there's always a nice comfy fan blowing heat from some equipment to warm you up.

What are the basic idea of nuclear submarines?
Nuclear submarines are powered by a nuclear reactor and they are completely independent of air, so there is no need to surface frequently.
Which countries have nuclear submarines?
The US, Russia, Great Britain, France, China and (recently) India have nuclear submarines.
Do nuclear submarines generate nuclear power on the submarine?
Yes, nuclear submarines generate nuclear power. There is a nuclear reactor on board (hence the tern nuclear submarine) which creates steam to drive the main engines to turn the screw(s).
What is todays submarines powered by?
Nuclear Energy

The PLA navy has more than 225,000 personnel and is thought to have as many as 70 submarines, 10 of them nuclear-powered
Is plutonium in navy nuclear applications?
Plutonium can be used in nuclear reactors for nuclear propulsion of ships and submarines.
Do submarines need gas?
No - all submarines, be it nuclear or diesel-electric, use diesel fuel, either for primary engines (DE) or backup generator (nuclear).
Are the UK's nuclear missiles based in submarines?
Since its free-fall nuclear weapons arsenal was decomissioned in 1998, the United Kingdom's only means of nuclear weapons delivery is via submarines and SLBMs.
