- Home improvement stores (Lowe’s, Home Depot) offer competitive pricing but may lack expert advice.

Top 5 Places to Buy a Gas Water Heater
1. Home Improvement Stores (Lowe’s, Home Depot)
Big-box stores stock popular brands like Rheem, A.O. Smith, and Bradford White at competitive prices. Their inventory visibility lets you check stock online, and many offer same-day pickup. However, their staff may lack plumbing expertise, risking incorrect sizing or compatibility issues. Some models are builder-grade with cheaper components to meet retail price points.
2. Local Plumbing Suppliers
These wholesalers (e.g., Ferguson, Hajoca) sell professional-grade units often unavailable at retail stores. Brands like Navien or Noritz dominate here. While some require a contractor’s license, others serve homeowners directly. Expect better warranties and technical support, but prices run 10-20% higher than big-box stores.
3. Online Retailers (Amazon, SupplyHouse.com)
Online shops provide detailed specs and customer reviews, with options like SupplyHouse specializing in HVAC equipment. However, shipping heavy water heaters costs $150-$300, and returns are cumbersome. Verify local installation codes before buying—some units aren’t certified for all regions.
4. Direct From Manufacturers
Companies like Rinnai or Takagi sell tankless models directly, often with extended warranties or rebates. This cuts out middleman markups but may delay delivery. For example, Rheem’s website redirects buyers to local dealers for inventory checks.
5. Local Plumbers (Full-Service Option)
Hiring a plumber (tips here) ensures proper sizing, permits, and installation. Many bundle equipment markup with labor, but you’ll avoid DIY pitfalls like gas line leaks or venting errors. As plumbing expert Mike Lombardi notes, “A $50 savings on the unit can cost $500 in repairs if installed wrong.”
Comparison Table: Where to Buy a Gas Water Heater
| Retailer | Price Range | Warranty | Pros | Cons |
|---|---|---|---|---|
| Home Depot/Lowe’s | $400-$1,500 | 6-12 years | Instant availability, price matching | Limited expert guidance |
| Plumbing Suppliers | $600-$2,000+ | 10-15 years | High-quality units, pro support | May require contractor |

3 Hidden Costs to Watch For
- Installation fees: DIY isn’t recommended for gas units. Plumbers charge $500-$1,500 depending on complexity (e.g., venting modifications).
- Disposal: Stores may charge $50-$100 to haul away old units. Local utilities sometimes offer free recycling programs.
- Permits: Gas line work often requires inspections ($75-$200). Skipping this voids warranties and risks safety issues.
FAQ Section
Can I install a gas water heater myself?
Gas line and venting work should always be handled by a licensed professional due to explosion and carbon monoxide risks. Electric models are more DIY-friendly.
What’s the average lifespan of a gas water heater?
8-12 years, but maintenance (e.g., annual flushing) can extend it. Tankless models last 15-20 years.
Are tankless gas water heaters worth it?
Yes, for homes using 40+ gallons daily. They cost 2-3x more upfront but save 20-30% on energy bills. See our tankless vs. traditional comparison.
Final Recommendation
For most homeowners, buying from a local plumbing supplier or full-service plumber ensures the best balance of quality, safety, and long-term value.
