Well, I just received my Winter electricity Bill after the first comparable Season using the halogen oven. And believe me, the thing is never off. My Daughter uses it to cook my Grandson's teas, then it is usually back on for ours - rather than the hob, grill or main oven. In fact, our oven usage, in total has probably doubled, equivalent to probable use of main oven.
So, what has this excessive use done to my kwh over the Season? It has CUT it by 10%

- and the reduction in prices means my Bill is 24% cheaper a month! All from the only change, a little halogen oven - I love it
Dave.
