The Heat Generator is a machine added by Mekanism, which is used to produce energy from combustible materials and Lava (see Usage).



Energy production

Picture 1: The Heat Generator in passive mode produces energy from surrounded lava.

The Generator needs combustible materials (e.g., Coal) or Lava) to produce energy. Lava can be supplied manually via storage items like the Basic Gas Tank or through Basic Fluid Pipes.

The Generator can produce energy passively from adjacent Lava blocks, as shown in Picture 1. In this mode the generator produces smaller quantities of energy compared to consuming combustibles but can produce energy constantly without consuming materials. Every block of Lava next to the generator raises the heat input and subsequently energy production.

The produced energy can be delivered to a connected Basic Universal Cable, an adjacent machine or Basic Energy Cube, or it can be used to charge portable energy storage cells like the RE-Battery and items inside the GUI.


Picture 2: GUI of the Heat Generator.

Right-clicking on the machine opens its GUI (shown in picture 2).


  • The slot on the left can be used to input combustible materials or Lava Buckets.
  • The filling level indicator in the middle shows the internal storage which is expressed in "mB Lava". For example, one piece of Coal is transformed into 800 mB of lava and stored in the internal storage.
  • The green slot and the vertical meter on the right side accepts rechargeable portable power storage containers (such as a Basic Energy Cube or RE-Battery) and displays the current energy in the machine respectively.


  • The upper-left button changes the displayed heat system between °K (Kelvin), °C (Celcius), °F (Fahrenheit), R and "+STD". The change only affects the display; the energy is still available in all forms inside the system.
  • The middle-right button opens the GUI to configure the access rights for the machine.
  • The lower-right button changes the behavior to Redstone:
    • "High" = operates only if a signal is received
    • "Low" = operates only if no signal is received
    • "Disabled" = operates independently from Redstone signals
