Heating techniques probably varied by region and epoch.
The Short answer is: 1. Heated 'masses'. and 2. building fire was a science to people.
A common house design going back a couple hundred years includes a centrally located large fireplace and hearth to serve various purposes. Seeing as fire was the most advanced technology the people in question had at the time, fire would have been very central in their lives.
A large fireplace capable of safely burning full size logs, several feet long would need to be sturdily built. With brick or stone enclosures (and chimneys) several feet thick.
A fire place 5' tall x 7' long x 4' deep, could possibly involve over 100 cubic feet of stone heated to 800 or 900 degrees. There is what you call a 'heated mass'. Five or Six or who knows how many strategically placed large fires could certainly provide enough heat for a large structure.
Furthermore the actual building of a fire was a highly advanced skill for both men and women. They understood that different types of material burn at different rates, lights, and heats. If somebody had the means, one could have materials (wood) from other regions brought to them.

Square keep castles (or stone keep castles) were made out of stone; you can probably tell from the name! Hope this helps.

Becuase of me
This depends on what type of castle your referring to. In the Norman times, there were two different types of castles built. There were Motte and Bailey castles and Stone keep castles (Stone castles). The Motte and Bailey castles were made out of wood and the Stone keep castles were made out of stone (obviously).
they all did IT.
No, all castles are different in some way. These are the different types of castles: * Motte and Bailey castles (made out of wood) * Stone keep castles or just stone castles (made out of stone) * Concentric castles (also made out of stone)
