Have you ever wondered how both of us got information before the internet? When I guess about it, I find it weird because the things that I normally search for, I don’t guess I can instantly get the answer by calling someone I know, however for instance, when I thought about purchasing an whole-house air purifier for my home, I used the internet to help myself and others to make my decision; I don’t guess anyone who owns an whole-house air purifier, so there was no 1 to call & ask the questions I needed an answer to. I could have called a local Heating & A/C provider, but the internet was far more convenient, and a year ago, when I needed to replace my sizzling water heater, I went straight to the internet to research which gas furnace was better for me. There are more than one types of sizzling water heater, 1 that is tankless & the other has a tank. The water gas furnace that broke had a tank, so I was trying to decide if I should switch to a tankless; Based on what I found during my research, the tankless water gas furnace was the best choice. It has a better lifespan than the tank water gas furnace & it is more energy efficient. In fact, the Department of Energy website mentions that if I use less than 41 gallons of water per morning, then a tankless water gas furnace could save upwards of 34% on my energy bill. I found out all of this information without having to contact a plumber, & I was able to make my decision just from spending a few minutes on the internet.
