NYC made history this week by releasing a huge dataset of actual building performance—including some blank spots for buildings that didn't comply with the law.

There are two primary types of water heaters: storage and tankless. In this column I’ll try to explain the differences between these two approaches and offer some guidance on choosing between them. (There are also “hybrid” water heaters with features of both that I’ll cover in a future blog post.)
