Frequently Asked Questions

Is a tankless water heater worth it?

For most homes, yes. Despite higher upfront cost ($1,500-$3,000 more than tank), they save $100-$150/year on energy and last 20+ years vs 10-12 for tank heaters. Break-even is typically 6-10 years.

Can a tankless water heater run out of hot water?

Not in the traditional sense โ€” they heat water continuously. However, they have a maximum flow rate (typically 5-10 GPM). Running multiple showers simultaneously can exceed capacity.
