I've been in hvac 36 years & don't agree with a lot of the suggestions for "saving energy" a lot of them will in fact cost money as well as problems with the newer equipment. The more sensible "rule of thumb" for thermostats used to be unless you are going to be gone more than 72 hrs. don't vary the temp more than 5 deg. 10 degrees for just an 8 hour period is asinine !, If the outside temp is low enough for the house to drop 10 degrees in that period this constant change is also hard on paint furnishings etc., the recovery time eats any savings & the biggest factor to consider with modern equipt is that if there is any issue with inadequate air flow i.e. sizing, dirty filters or too many vents shut off or blocked, the furnace will over heat & eventually shut itself off.Furnaces doing this creates probably 65% of no heat calls in the winter & a common response from people is "my old furnace never did that", As for these new "smart thermostats" I personally don't think the majority of consumers have any chance of recouping the cost, but think a lot of people just want the newest fanciest "toy" like the smart phone game, most of these will probably be outdated or have failed before ever recouping plus most people with these type of controls are constantly playing with them. I also feel that the High end variable speed "bell & whistle " models are not are good investment. They are becoming more reliable & most have a ten year part warranty which is better than the one or five year previously. in a lot of cases a step down from the top of the line to one with 2 stage technology & ecm motor is a better investment, none of these are any better than the way they are installed, a lot of contractors push the high end as it is better for them for obvious reasons, a lot of the savings depends on the efficiency &size of the house as well as the area it is in i.e. energy costs, climate.The best investment for energy savings is common sense !
OK, I've got a Nobel prize winning observation here: Put some freaking clothes on. Big time thermals, 2 layers of pants with 3 layers of shirts, 2 pair of socks, and a hat or beanie. If you run to your thermostat wearing shorts and a short sleeve shirt you deserve to lose your shirt.
Don't heat air- heat objects instead. Small wattage radiant heaters work best and they work in drafts, too. A 400 watter keeps me comfortable and the only time I run the central heat is to protect the pipes during a plunge.
I think LEDs are crap. I used them 2 yrs. ago on my wreath. Took them out last year and most didn't work. I had to search for lights again. By the time I got done, I had 4 sets of LEDs on my little wreath.
They don't have a long life. Yes, they were battery-operated for the wreath - I kept changing the batteries but it was actually the lights - I used the batteries for other things and they worked fine.
I don't put up a wreath until my b-day ( the 8th) and only run them for a few hours. I hate LEDs. Give me the mini-lights - brighter & they last. Can't find the battery operated minis anywhere now.
