The extremely low energy consumption hints/tips/projects thread.

Damn, not the right thread for classA amplifiers!

If you can run them during offpeak times then it is perfectly affordable.

Which is exactly what I do: http://www.diyaudio.com/forums/tubes-valves/71300-photo-gallery-455.html#post3291496

Oh dear. Here in the USA, public service announcements on TV tell us to lower our thermostats to 65 degrees to save energy. We already leave the thing at 50 degrees (in the winter) and wrap up under blankets. I wonder what they would sugest I lower THAT to?

Let's say you have a house that is drafty - very cold when windy - if you can reduce the infiltration you can save a lot of energy. While there is certainly a price to pay for a house that is "too tight" or one that doesn't manage moisture properly, older houses (such as my 1959 ranch) often can reduce their energy bill more cost effectively with weatherstripping than with insulation.

The payback on adding insulation in my attic is decades,where the payback on making my windows tighter is more easily measured in months.

Where I used to live I had a kerosene heater gobble up about 10 litres of kerosene in just 1 night during winter just because of drafts that couldn't be stopped, this is how cold it was when I eventually ran out:

Well, I set back as low as 52F when I am not home, and 65F when home - and my heating bill is about 40% lower than it was 4 years ago - just from weather stripping. This in Minnesota, which may or may not mean something to someone in OZ.
