I have lived in many homes and apartments, and one of those things I always keep my eye on is the water heaters. Those thing are prone to failure all the time, leaving you cowering in the shower as cold water sends chills down your spine. I know, I’ve been there. It’s far from pleasant. Good thing nowadays technology has allowed us to do away with traditional tanks in favor of tankless water heaters. Now installation and performance is much better, meaning years of happy warm showers.
