All depends on azimuth, roof angle and shading.
My installation is near perfect in all these respects.
The house was purchased with this in mind.
The installation is almost three and a half years old and will have
paid for itself in five years.

Only because you are indulging in legalised banditry on the rest of
us.

Ah. Another whinging socialist.


Would you have fitted panels if they didn't make you a large profit?
Obviously someone that cared about the environment and believed AGW was
a threat would have.

You aren't honest enough to admit you did it for the cash and sod all
else. Its why I installed cavity wall insulation 30 years ago as it
saved cash not because it saved the planet.

Both.
Renewable energy is the sensible way to go.

Nope, not for heating.

Only the brain dead can'tseethis.

Only the brain dead can't see that the cost of
renewable energy makes it unviable for heating.

99% of heating (as in conventional houses) is unneccesary.


Harry.. When will you take on board that its bloody impossible to
insulate any existing houses like that egg box one you live in.

Modern rooms are small enough as it is without half a yard of Celotex as
desirable as its properties might be!...


Its pointless fitting as much insulation as harry..

say 50% of the heat goes through the walls, an inch of cellotex will
reduce that to about 5%, 2 inch to 2.5%, 4 inch to 1.25% so as you see
adding another 30 inches is going to save you about 1%. The required
changes in air will use about ten times as much energy so fitting a heat
exchanger will save more and take up less space.

Drivel.
Also whole house ventilation is a waste of space.
