Tankless vs Tank Water Heater Calculator
Compare the long-term total cost of ownership between traditional tank water heaters and on-demand tankless systems.
When deciding between a tankless (on-demand) and a traditional storage tank water heater, there are several key factors to consider:
- Upfront Equipment Cost: Tankless units typically cost 2-3 times more than traditional tanks for the equipment and installation.
- Energy Efficiency: Tankless units avoid standby heat loss (the energy wasted keeping a tank of water hot when not in use), making them up to 34% more energy efficient for homes that use less than 41 gallons of hot water daily.
- Lifespan: A traditional tank water heater usually lasts about 10-15 years, while a tankless unit can last 20+ years. Over a 15-20 year period, you may need to buy two tank heaters vs one tankless unit.
- Unlimited Hot Water: Tankless systems provide a continuous supply of hot water, meaning you won't run out during consecutive showers.
