Manual boost is not used during the night, so is not counted in used kWhs. |

Depends what you mean by "boost" I'd use the top heater most of the time, and only turn the bottom one on when I wanted a bath. No need to heat the bottom of the tank at all most of the time - half a tank should be OK or a shower. Andy |
