Heat Accumulator

The Heat Accumulator is a machine added by Prodigy Tech. It is used to charge a Heat Capacitor inserted into it. To do so it must be provided with Hot Air at least as hot as the capacitor's target temperature.

Unlike other Hot Air machines, it does not transmit any Hot Air.

Charging speed
The Heat Accumulator does not get sped up the same way other Hot Air machines do when provided with higher temperatures. The time (in ticks) it takes to replenish worth of charge in the inserted Heat Capacitor can be calculated using the following formula:

$$T = max(20, \frac{300}{10 + \frac{(heat - targetheat) \times 2}{targetheat}})$$

Where:
 * T is the final time
 * heat is the heat the Heat Accumulator is currently receiving
 * targetheat is the capacitor's target heat

This gives the following times to fully charge a given Heat Capacitor at some common temperatures:
