Costco does not sell gas water heaters; they primarily offer a selection of electric water heaters and related accessories in their home improvement section.
Costco offers gas water heaters both online and in select warehouse locations. While availability varies by region, members can purchase tank and tankless gas water heaters through Costco’s partner network, often with installation services included.
Costco’s Gas Water Heater Selection
Costco primarily sells water heaters through their third-party partners rather than stocking them in all warehouses. Their offerings include:
- Rheem gas tank water heaters (natural gas and propane)
- Tankless gas water heaters from brands like Rinnai
- High-efficiency condensing models
- Hybrid heat pump water heaters with gas backup
Online vs. In-Store Availability
While some Costco locations display water heaters, most purchases are arranged through their home installation services. Online offerings frequently include special promotions like bonus Costco cash cards with purchase.
Costco Water Heater Installation Process
Costco partners with licensed professionals for water heater installations. The typical process involves:
- Online request or in-store inquiry
- In-home assessment (required within 40km of a warehouse)
- Professional installation with warranty coverage
Installation Considerations
Gas water heaters require proper venting and gas line connections. Costco’s installers handle these requirements, but you may need upgrades if your home lacks adequate gas supply. For more on gas water heater operation, see our guide on how gas water heaters work.
Costco vs. Competitor Pricing
While Costco’s prices are competitive, they may not always be the lowest. Consider these factors:
| Retailer | Price Range | Installation Included |
|---|---|---|
| Costco | $800-$2,500 | Yes (through partners) |
| Lowe’s | $600-$2,200 | Additional cost |
| Home Depot | $550-$2,300 | Additional cost |
Special Offers and Warranty
Costco frequently runs promotions on water heaters, including:
- $200-$500 Costco shop cards with purchase
- Extended warranty options
- Special financing offers
Their standard installation includes a 1-2 year labor warranty, with manufacturer warranties covering parts. For comparison of top brands, read our Bradford White vs Rheem water heater analysis.
Alternative Purchase Options
If Costco doesn’t service your area or you want more selection, consider:
- Local plumbing supply houses (often better pricing than big box stores)
- Direct from manufacturer programs
- Utility company rebate programs
