Best Gas Water Heater FAQ

1. What Is The Difference Between Electric And Gas Water Heaters?
One of the main differences between electric and gas water heaters is that gas options cost less to operate on a monthly basis than electric models. They are also more effective at supplying larger homes and businesses with a constant flow of hot water.
2. What Tank Size Should I Choose For My Gas Water Heater?
Choosing a water heater with a large enough capacity to handle multiple water users is essential, and the number of people in your home will affect what size you need. Typically, a 50-gallon water heater can sufficiently supply a household of up to 4 people, but to figure out the exact size you need, it’s best to estimate your peak hour demand.
