OK, I don't think you know what KVAR and KVA actually are.
The R in KVAR stands for Reactive. It's about powering inductive loads. That's why I was talking about reactive loads. Nothing to do with "HEAT" really.
It sounds like you've gotten your hands on some equipment that gives you KVA and KVAR readings, but you don't understand what they are so you've worked yourself up into a bit of a tizzy.
Go and read some books on basic electrical engineering, and try to understand what is going on instead of getting angry about something which is new to you, but old to everyone else.
