Heat Generator produces very little power in passive mode

Issue description:

The Heat Generator when surrounded by lava should (according to the wiki, and the discussion in Issue #4697) produce 5J/t per side (assuming the default config). However it is producing considerably less than this. In a test world with just Mekanism and MekanismGenerators, I got the following results

Lava Blocks Generated Power
1 161.06 mJ/t
2 624.15 mJ/t
3 1.36 J/t
4 2.34 J/t
5 3.56 J/t

Looking through the code for the Heat Generator, what seems to be happening is that it is creating 5 heat per tick per side (in the getBoost() method), then the heat dissipation simulation run, a chunk of the heat is dissipated and the remaining amount is used to generate electricity. This seems to explain the non-linear numbers I'm seeing as less heat is lost to the surrounding blocks when the surrounding blocks are lava, at least I think so.

This might be what's intended but it's resulting in very low outputs for passive generation.

Actually, I've just tested active generation, and there's similar behaviour. A generator is only producing 74.92 J/t, not the 150 I was expecting.

Steps to reproduce:

  1. Create new world
  2. Place heat generator surrounded by lava
  3. Check energy output

The wiki is not well maintained, so treat its numbers as dubious at best

It does look to be intended, as the heat loss is part of the energy calculation
