If you’re a homeowner in Fullerton, CA, and your hot water heater has finally given out or you’re planning a proactive upgrade, you’re likely asking, “How much does it cost to pay someone to install a hot water heater around here?” It’s a smart question. Installation costs can vary widely based on several factors, and knowing what to expect helps you budget more effectively and avoid surprises.
At The Water Heater Warehouse, we’ve helped thousands of Fullerton residents find reliable, affordable solutions for their water heater needs. Here’s a breakdown of what goes into the cost of hot water heater installation and what you can expect when you work with a professional installer.
Factors That Influence Installation Costs
In Fullerton and the surrounding areas, installing a hot water heater typically costs between $1,200 and $3,000. Several key factors contribute to this range:
1. Type of Water Heater
- Tank water heaters (standard units) are generally less expensive to install. Depending on capacity and brand, installation may cost between $1,200 and $1,800.
- Tankless water heaters offer energy savings and a longer lifespan, but they usually cost more to install between $2,000 and $3,000 because of the additional labor and plumbing modifications required.
2. Labor and Permit Fees
Licensed plumbers in Fullerton typically charge $75–$150 per hour. Hot water heater installation usually takes 2–4 hours, but the final price may include:
- Permit fees required by the city (usually $100–$250)
- Disposal fees for removing your old unit
- Plumbing and electrical adjustments if your setup doesn’t meet current code
3. Location and Accessibility
Is your water heater tucked away in a tight attic space? Or installed in an easy-to-access garage? Installation in tight or difficult-to-reach locations can increase labor time and costs.
4. Gas vs. Electric
Gas water heaters may require venting upgrades or gas line adjustments. These are often more involved than electric heater installations, potentially increasing the cost.
