Electric Tankless Water Heaters:
Pros – Generally easier to install, no venting required, smaller size, and typically lower upfront cost.
Cons – A storage tank may be required for higher operational costs in areas with high electricity rates and less efficiency in very cold climates.
Gas Tankless Water Heaters:
Pros – Lower operational costs due to lower natural gas prices, better performance in cold climates, and more efficient for high-demand households.
Cons – Requires venting, more complex installation, and typically higher upfront cost.
In Colorado, where heating water at high altitudes requires more energy, gas tankless water heaters tend to be more energy-efficient compared to electric models.
