	For any heat pipe entity with one input connection on one side and one output connection on another, this entity ~~with~~ lower the temperature by <code>1 + (P / 15) °C</code> with P being the power going through this entity expressed in MW.		For any heat pipe entity with one input connection on one side and one output connection on another, this entity will lower the temperature by <code>1 + (P / 15) °C</code> with P being the power going through this entity expressed in MW.

	A [[heat exchanger]] must heat up to 500°C before it can generate steam. And the maximum temperature of a heat generator (such as a nuclear reactor) is 1000°C. As such, the temperature difference between a heat source and the heat exchanger is at most 500°C. We can express the maximum length of a straight line of heat pipe as <code>500 / (1 + P/15)</code>.

As such, the temperature difference between a heat source and the heat exchanger is at most 500°C. We can thus express the maximum length of a straight line of heat pipe as <code>500 / (1 + P/15)</code>.

	For example let's take a single nuclear reactor outputting 40MW of heat power to a single line of heat pipes. The furthest that line can go is <code>500 / (1 + 40/15)</code> which is around 136 heat pipes long.

The furthest that line can go is <code>500 / (1 + 40/15)</code> which is around 136 heat pipes long.

	A nuclear reactor can also be used to transfer heat in a similar manner as a heat pipe, whether or not it's fueled. In this case, the reactor will drop the temperature by <code>1 + (P / 387) °C</code>, with P again being the power in MW going through the entity. Note that this is an approximation, the actual value measured is supposed to be 200000/517 or about 386.847.

Note that this is an approximation, the actual value measured is supposed to be 200000/517 or about 386.847.

	That being said, the nuclear reactor entity is also much bigger, meaning that we must compare it to 5 lines of 5 heat pipes instead of just a single one. The nuclear reactor will thus lower the temperature 5 times less with near-zero power going through it, and nearly 26 times less when approaching infinite power, compared to those lines of heat pipes.

Different entities consume different amounts of heat to prevent freezing, but they do not have the temperature requirements of a heat exchanger.

	Heat pipes have a heat capacity of 1 MJ/°C. Thus, they can theoretically buffer 500 MJ of heat energy across their working range of 500°C to 1000°C, making them a space-efficient energy store. However, because temperature needs a drop of greater than 1 degree before it will "flow," you can't raise them all the way to 1000°C or drain them all the way to 500°C, so the practical energy capacity will depend on the layout.
