-Exchanges heat between two pipe networks very quickly, ~10x as fast as the [[Kit (Small Direct Heat Exchanger)‏‎|Small Direct Heat Exchanger]]. It's counterpart is the [[Kit (Counterflow Heat Exchanger)‏‎|Counterflow Heat Exchanger]]. <small><sub>pun intended</sub></small>
+Exchanges heat between two pipe networks very quickly. Comes in two variants, large and super large, which both act as bulkier upgrades to the [[Kit (Small Direct Heat Exchanger)‏‎|Small Direct Heat Exchanger]]. It's temperature-swapping counterpart is the [[Kit (Counterflow Heat Exchanger)‏‎|Counterflow Heat Exchanger]]. <small><sub>pun intended</sub></small>
 ==Usage==
 It's purpose is to equalize the temperature of two pipe networks without allowing their contents to mix. <br>
-The heat exchanger does not have an internal volume and instead transfers heat directly between the two input pipe networks. A meter on the side displays the heat exchange rate in joules per tick.
+The heat exchanger does not have an internal volume and instead transfers heat directly between the two input pipe networks. A meter on the side displays the surface area and heat exchange rate in joules per tick.
 ===Heat Transfer===
 Heat will flow from warmer to colder at a rate that increases with a greater difference in temperature. Newton's law of cooling can be used to approximate the rate of heat transfer according to the equation:<br>
