Benefits of Tankless Water Heaters: 

  • Quantity:
    Tankless water heaters are transforming the way people heat water for their homes and businesses. A tankless water heater can turn any water source into hot water, meeting demand at any scale. When you’re free from the limit of tank size, hot water is pretty much limitless.
  • Quality:
    Water quality tends to be better as well because tankless heaters don’t build up rust and scale as traditional heaters do. Best of all, these cutting-edge water heaters save energy, space, and money. Rinnai® heaters, in particular, are ENERGY STAR® approved, so you can invest with complete confidence.
  • Efficiency: 
    Compared to a standard water heater with a tank, tankless water heaters can realize a 33% savings because they only heat the water on-demand, as opposed to continually keeping a full tank heated. Traditional water heaters even need to keep the tank heated when hot water is not in use! Needless to say, a more efficient mechanism is not only better for your pocketbook, but also more eco-friendly as well.

Tankless water heaters are revolutionary, which is why so many people are surprised at how affordable they are. When you decide to upgrade to a tankless water heater, choose Callahan’s Gas & Appliance in Centreville!
