T-Stat Optimal Efficiency?


Hi All,

I recently installed a nice digital programmable thermostat.

I live in the Northeast.

Here's my ideal T-stat setting (purely for reasons of frugality):

MOrning (upon waking) 60

Late morning until around 5:00 - 55 (or even 50)

Dinner time until bedtime - 60

While I'm sleeping - 55

A few questions:

1) Is the 5 drop worth it in terms of the time it will take the boiler to run to get the house back to 60? My feeling is absolutely, especially if it's turned down all day. My friend/tenant seems to think it will take the furnace "6 hours" to get back up to 60 (or whatever).

2) Would it be more efficient to simply run the T-stat at 60 24/7? I have a very hard time believing this.

Is there some kind of "magic formula" to figure out the ideal differential between high (keeping me warm while I'm there) and low (cruising speed at "cool" throughout the day whilst no on is there)?

Personally I find 60 quite comfortable. I could even tolerate 55. My friends apparently can't take anything less than 64 in the morning. So I'm not sure what to do about this. Would like to find a way where they can be comfortable, but also turn it down during the day so I can save my shirt, if indeed it is more efficient that way.

Thanks for any advice on the matter.

Set back will save money.
How long it will take to recover, varies with each system.
