- Speaking of heating systems, switch our your old thermostat with a new smart thermostat. Many have geo-fencing capabilities these days so will go into hibernation when you leave and fire right back up once you return.
There are some savings with this but it isn't much when it is short periods of time. Your house loses X amount of BTU's per hour and that doesn't change much as the inside temp drops. The amount of heat that you didn't put into the house has to be made up when you return. Where the savings can occur is efficiency in the heating system, longer cycles on units utilizing a fuel that burns like gas increase their effcicny for a lot of reasons.
If you have regular resistant electric baseboard this doesn't apply because it is always 100% efficient. For heat pump they have variable efficiency depending on outside air temperature and since you typically wouldn't be at home during the warmer part of the day this can increase
your energy costs.
Since they take so long to catch up it's not very practical anyway.
Same thing applies with water heaters. Turning it off for the entire day really isn't saving you anything. However if you live in area with variable electric rates where they are lower at night you can see a significant cost savings running it only when the rates are lowest. There is little energy savings, just the dollar cost. Modern water heaters lose very little heat, for one or two person household this is very doable if you don't need hot water during the day much. If you need hot water during the day you can jack up the temperature it heats to when costs are lowest. Just make sure to install mixing valve so you don't end up scalding anyone.
