Agh!!!!!

Why does whatever you set the heating to in July suddenly
become too cold in December? *IT'*S *THE* *SAME* *FECKING*
*TEMPERATURE*!!!!!!!!!!!!


Journalists' nonsense or a figure of speech, but not incorrect.

Thermostats work on the air temperature which could, given an ideal
heating system, remain constant at, say, 21 degC.

Human comfort is based on heat losses by convection (air temperature),
radiation and cooling by evaporation. So, in cold weather, the
surrounding radiant surfaces (walls, floors, ceilings) are colder so
you feel colder although the air temperature stays constant. You lose
more heat by radiation. ISTR that human comfort conditions are best
controlled by a temperature sensor in a b;ack ball of about 6"
diameter; can't recall what it's called though.

Similarly, UFH SHOULD allow you to feel comfortable at a lower air
temperature.

So there.
