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 — they heat water continuously. However, they have a maximum flow rate (typically 5-10 GPM). Running multiple showers simultaneously can exceed capacity.
Why does tankless water heater cost different in Houston than other cities?
Houston's costs reflect local labor rates driven by the energy-healthcare-aerospace economy, humid-subtropical climate conditions that affect materials and scheduling, and relaxed permitting requirements. The competitive labor market also influences competitive pricing.
