underfloor heating - running costs

It doesn't say what the prices represent. KW, therms. What? One thing is for certain in the 1960/70s gas heating was going in like wildfire. Those who could not afford it fitted gas fires. If electric was so cheap gas fires would not have been sold at all,as electric fires were cheaper than gas and no fitting expense. Gas was cheaper to run, that is why it took off like a rocket in the 1960s - High Speed Gas, remember that?

Have another look. According to page 20, in 2002 electricity is cheaper than gas. As we all know this is balls. The graph is only projecting backwards and forwards from 1990, which is very misleading.

It doesn't matter. The figures are normalised to 100 at 1990 and all the other figures and graphs are relative to that.

From the definitions on pp26:-

"Data relating to the energy content of fuels are on a gross calorific value basis. Prices are presented in real terms i.e. the effect of inflation has been removed by adjusting each series using the GDP deflator."

There's no need. It's abundantly clear that this is normalised data to 1990 and shows comparative prices.

You could normalise at any other date and easily calculate the numbers.

I dunno. Judging by the mutated look of most deep sea fish, that happened years ago,
