Mouse heat is the amount the heat goes up when you click on the object. Heater is like an auto clicker, but it starts in reverse to represent heat escaping. The object always loses heat at the same rate, but when you turn on the heater, it starts getting a constant supply of heat, canceling out the loss of heat, only a little at first, so the heat still goes down, but more slowly, then enough for the heat to stay the same, and then enough for the heat to go up, only a little at first, but the more you upgrade the heater, the faster the heat will go up.
There might be more changes at some point, but this will be around as it is for a while.
