However, he ignores the fact that he's also losing 45 watts of heat.
To keep his house at exactly the same temperature, an extra 45 watts
of heat need to be pumped out by whatever heating system he has, for
as much of the year as he needs any heating at all. Admittedly,
that may be a bit cheaper if it's gas-fired, but it's still the same
amount of energy, so it's unlikely to have a huge impact on climate
change.

You are assuming that those 45W of electricity are converted to 45W
of heat with 100% efficiency which is clearly not true.

Where else do you think it goes?

Hmm, maybe powering the standby circuitry, IR receivers, etc?

Which is ultimately turned into heat.

OK! Thanks to all who put me straight. Ultimately, yes it ends up as heat,
but its an expensive way to heat your house. I think I'll be sticking to gas
CH instead of filling my rooms with wall-warts. :-)
