The purpose of getting any whole-home heating method is to be able to have an upper hand when it comes to temperature control in your home, but if you are wondering if you should make the move from an analog to a digital thermostat the answer is yes, however the only thing the analog one has over the programmable one is that it is slightly cheaper than its counterpart but due to the level of temperature accuracy it ends up adding to your energy bill, but according to the Department of Energy, the programmable regulator saves up to 10 percent on your energy bill each year, however with them, you can program in yearly settings to adjust the indoor comfort when you are not in the house or asleep, and by doing this you allow your electric heating system to not operate as often when you do not need it or are away and this is one of the major energy-saving tips when it comes to a programmable regulator.
It is possible to have a zone control replacement if you have an electric heat pump as your central heater, and coupled with a programmable regulator you can adjust individual temperatures in the different zones of your home.
This also applies to radiant floor heating. If you do not have such a method and you are interested in one you should call your local repair provider and have a heating worker tell you what is needed and if it is possible with the replacement that you have, then you could also wait till the next time the heating business is coming for a gas furnace/heater tune-up or a gas furnace furnace repair to inquire.
