As you may have heard, new regulations went into effect earlier this year that required design changes in residential water heaters.  The new style is more efficient, but has a significantly larger diameter.  Here’s a “Pre-2015” model on the left along with a “Current” model on the right.

If you think your water heater might be due for replacement, take a look at the space that’s available where it’s installed.  Plan ahead so that if and when your water heater does fail, you’re not caught by surprise with a space that won’t accommodate the new style heaters.
