Frequently Asked Questions

Common questions about tankless water heaters in Dallas.

How much does a tankless water heater cost in Dallas?
Tankless water heater installation in Dallas typically costs $2,500-$5,500 including the unit and professional installation. Gas units range $2,500-$4,000, while electric units are $1,800-$3,000. High-efficiency models from Rinnai or Navien may cost more but offer greater energy savings.
How long do tankless water heaters last?
Tankless water heaters last 20+ years with proper maintenance, nearly double the lifespan of traditional tank water heaters (10-12 years). Annual descaling and filter cleaning extend the life significantly.
Are tankless water heaters worth it in Dallas?
Yes! Dallas homeowners save $100-$300 annually on energy bills. Tankless units are 24-34% more efficient than conventional tanks. Plus, you get endless hot water, space savings, and a 20+ year lifespan. Most homeowners break even in 5-7 years.
Can a tankless water heater run two showers at once?
Yes, properly sized tankless water heaters can handle multiple fixtures simultaneously. A typical whole-house unit (7-11 GPM) can run 2-3 showers at once. We calculate your home's peak demand to recommend the right size.
Do tankless water heaters work during power outages?
Gas tankless water heaters need electricity for ignition and controls, so they won't work during outages without a battery backup. Electric units also require power. Consider a UPS backup system for uninterrupted hot water.
How often does a tankless water heater need maintenance?
Tankless water heaters should be descaled annually in Dallas due to our hard water. The process takes 1-2 hours and costs $150-$250. Regular maintenance prevents mineral buildup and maintains efficiency.
What size tankless water heater do I need for my Dallas home?
Size depends on your peak hot water demand and groundwater temperature. For Dallas, a 7-9 GPM unit handles most 2-3 bathroom homes. Larger homes or simultaneous use may need 10-11 GPM. We perform a free assessment to determine the right size.
Which is better: Rinnai or Navien tankless water heaters?
Both are excellent. Rinnai offers proven reliability with the longest industry track record and excellent warranty support. Navien features innovative condensing technology with the highest efficiency ratings (up to 98%). We recommend based on your specific needs, budget, and installation requirements.
Can I switch from a tank to tankless water heater?
Yes! Converting from tank to tankless is common. It requires gas line upgrades (for gas units), electrical updates, and venting changes. Installation takes 4-8 hours. We handle all conversions and ensure code compliance.
Do you offer tankless water heater financing in Dallas?
Yes! TAB Home Services offers flexible financing options for tankless water heater installations. Plans include 0% APR for qualified buyers and low monthly payments. We also accept all major credit cards and offer senior/military discounts.
