The world is for sure changing in many ways. More so every single day. Look at where technology is at. Some of it is good and some of it is bad. However what has really advanced is heating and air conditioning technology. Within the last 20 years along heating and air conditioning technology has advanced so much it rather is crazy. If you think about the things we have like radiant heated floors, portable space heaters as well as portable air conditioning systems that have tons of power and also smart thermostats more than anything else. I never thought that I would see the day where a thermostat to control your central heating and air conditioning system from anywhere in the world would even be possible. Also I can tell you that the energy companies are not very happy with smart thermostats. This is because smart thermostats help save tons of money on your monthly energy bills. And this is making it so that the energy companies can no longer rip you off and charge you high dollar for running your central heating and air conditioning system unit just to have well needed indoor comfort. This is why I love my smart thermostat. I have had a smart thermostat for a long time now. Going on almost 10 years. It has saved me so much that it nearly paid for my central heating and air conditioning system unit! That is how much savings a smart thermostat can give you in energy use if you program it right.
