I am not as old as dirt, at least not yet. However, thinking back to my childhood brings up some very distinctive differences in the day and age. I grew up in a very rural area where nature surrounded us. I remember if I said I was bored, I had two options. Those options were, to go outside or clean the bathroom. So, I spent a ton of time outside. Except in the winter when I was shackled by short days and cold temperatures. But, man did we stay warm. HVAC as we know it now was not part of how I grew up. Granted, I was raised in a house that was already 50 years old back then. But, there were no air ducts or forced central air heating and cooling units. No, our house had this enormous boiler in the basement. The thing reminded me of some living beast from a bad dream. The boiler heated up all that water which then flowed to radiators throughout the home. I was taught a very healthy respect for the radiators. They got hot so, I was always leery of getting too close to them. Of course, during an indoor football game, I went head first into one of the radiators. I not only knocked myself out but, also gave myself a bit of a burn on the neck. Those radiators gave off the best heat. It was cozy and also had a humidity factor to it. I miss that humidity in the winter. Now, my HVAC does more sucking up of humidity to my chagrin. I’ve often thought about installing geothermal heating in my home. The heat is transferred by water through tubing in the floor. I would just love to walk around barefoot all winter. Would be like the old radiators but, even better.
