The Pros and Cons of Each Type of Water Heater

The last thing you want to do after waking up at the crack of dawn is wrestle with your water heater, hoping to get just a 10-minute hot shower out of it. Instead, trust that you’ll have reliable, hot water all year long by spending a few minutes learning about which water heater is best for your home and family’s needs.

Conventional Models
