RE: Do setbacks save energy without compromising comfort?

If I may comment, from a pure physics standpoint, I think its pretty much certain that the temperature of the intake air (which I think is what @catho...

Thanks I've had a scan and think I possibly understand what they are saying, but can you summarise what conclusions you draw as you know better ...
