Hmmm, slightly off topic but here we go.
I have just had delivered, and installed, a new Gas Cooker. I am in the UK.
It seems to me that the cooker is woefully inadequate. A standard ring with a standard pan that fits the ring, will not make a pan of chips (french fries).
Similarly, the oven, which has a control up to Gas Mark 8, will not heat the oven higher than Gas Mark 5, and 45 minutes at Max failed to brown properly a Poussin for dinner tonight, and the garlic bread was similarly uncooked, so my breath is going to stink tomorrow.
But the question is, how might you measure the power output of such a cooker to determine whether there is or isn't a problem with it? All I know is that according to the Gas Safety Certificate given to me by the installers, it is rated at 9KWHr. (It has an oven and grill (mutually exclusive use), 2 standard rings, one small one and one large one. I haven't a clue what this 9KWHr figure actually means in practice)
Now, I know there are methods of checking microwave power by boiling a known quantity of water and timing it, so is there perhaps a similar method for a gas cooker? (Obviously more difficult than the Microwave because the efficiency of heating is going to be vastly different and very subjective).
Cheers,
Gareth.
