cold

[JoeyB]

My 70 year old detached house has solid walls and is always cold despite having red hot central heating which is expensive to run.

What is the problem

[Clanad]

Most likely insufficient or total lack of insulation.  This is especially important in the ceiling areas...

[hopalong]

Could be draughts. 

[woofgang]

large single glazed windows? damp? exposure to cold winds? poorly placed central heating? radiators the wrong shape (small and thick instead of larger and flat?)

[smudge]

Our house has full central heating, but we have two open fireplaces for burning coal/logs. No matter how long the heating is on for, we'll always get down draughts from these chimneys!
