Is Tankless Right for You?
Endless Hot Water
Tankless water heaters heat water on demand as it flows through the unit. You never run out of hot water, even when multiple showers, the dishwasher, and laundry are running at the same time.
Lower Energy Bills
Because tankless units only heat water when you need it, they eliminate the standby energy loss of keeping a tank hot 24/7. Most homeowners save 20-30% on water heating costs after switching to tankless.
Longer Lifespan
Tankless water heaters typically last 15-20 years with proper maintenance, nearly double the lifespan of a traditional tank water heater. That means fewer replacements over the life of your home.
Space Savings
Tankless units mount on the wall and are about the size of a small suitcase. They free up valuable floor space in your utility room, garage, or closet compared to a bulky 50-80 gallon tank.
Cleaner Hot Water
Without a storage tank where rust and sediment can accumulate, tankless water heaters deliver fresher, cleaner hot water every time you turn on the tap.
Tankless Water Heater Costs in Fort Smith
Tankless water heaters cost more upfront than traditional tank units, but they last longer and deliver significant energy savings over time. Here’s what Fort Smith homeowners can expect:
- Gas Tankless Water Heater: $2,500–$5,000+ installed
- Electric Tankless Water Heater: $1,800–$3,500 installed
- Whole-House Tankless Unit: $3,000–$5,500+ installed
- Point-of-Use Tankless Unit: $500–$1,500 installed
Why go tankless? Tankless water heaters heat water on demand — no standby energy losses from keeping a tank hot 24/7. They last 20+ years (vs. 10–12 for tank units) and can save Fort Smith homeowners $80–$100+ per year on utility bills.
Installation costs vary based on whether you’re converting from a tank system (which may require gas line upgrades, new venting, or electrical work) vs. a straight tankless-to-tankless swap.

Our Tankless Water Heater Installation Process
Installing a tankless water heater requires more expertise than a standard tank swap. Here’s how Riverside Heating Air Plumbing handles it:
1. Hot Water Demand Assessment
We calculate your household’s peak hot water demand — how many showers, faucets, and appliances run simultaneously — to size the right tankless unit for your home.
2. Site Inspection & Planning
We evaluate your current gas line capacity, electrical panel, venting setup, and water line configuration. If you’re converting from a tank system, we identify what modifications are needed.
3. Transparent Quote
You receive a detailed estimate covering the tankless unit, any gas line or electrical upgrades, venting modifications, permits, and labor. No surprises.
4. Professional Installation
Our licensed technicians handle the complete installation — mounting the unit, connecting gas/water/electrical lines, installing proper venting, and removing your old tank water heater.
5. System Calibration & Testing
We calibrate your new tankless unit’s temperature settings, test flow rates at multiple fixtures, verify gas connections, and ensure the unit activates properly on demand.
6. Owner Training
We walk you through your new system’s controls, explain the maintenance schedule (annual flushing is recommended), and review warranty details.
Tankless installations typically take 4–6 hours. Call (479) 616-1364 to schedule your consultation.
