Replacing an Apollo water heater involves several variables that influence the total cost, including unit type, energy source, installation complexity, and local labor rates. Understanding these factors helps homeowners budget effectively and compare quotes confidently. This article breaks down typical costs, clarifies differences between common models, and offers practical tips to save without compromising safety or efficiency.

What An Apollo Water Heater Replacement Entails

Replacing an Apollo water heater starts with selecting the right model for household needs and energy goals. The process typically includes removing the old unit, preparing the installation site, installing electrical or gas connections, venting or exhaust updates, pressure testing, and a final system check. Permitting or inspection requirements may apply in some jurisdictions. Professional installation is recommended to ensure safety, compliance with local codes, and optimal performance.

Factors That Influence Replacement Cost

The total price combines the unit cost and installation charges, each shaped by several variables. The energy source (electric, gas, or solar-assisted), tank size (commonly 40, 50, or 60 gallons), and whether the model is a traditional storage tank or a tankless system significantly affect price. Labor rates vary by region and can reflect permit fees, accessibility, and the need to upgrade venting, electrical panels, or gas lines. The warranty terms and any required ancillary materials like an expansion tank or new shutoff valves also impact cost.

Typical Price Ranges By Type

Understanding the common Apollo models helps set expectations. The following ranges reflect installed costs in the continental United States and may vary by market.

<strongElectric storage tank (Apollo): Unit price often $500–$1,000; installed total typically $1,000–$2,500.
<strongGas storage tank (Apollo): Unit price usually $600–$1,300; installed total commonly $1,500–$3,000, depending on venting and gas line work.
<strongTankless electric or gas (Apollo): Unit price commonly $1,000–$2,000; installed total often $2,500–$4,500 due to complex venting, gas line upgrades, or electrical capacity needs.
<strongSolar-assisted or high-efficiency variants: Unit price can exceed $2,000; installed totals frequently $4,000–$8,000 if solar integration or significant electrical work is required.

Hidden Costs To Consider

Some expenses may not be obvious at the outset. Permits and inspections can add hundreds of dollars. Disposal fees for the old unit and a potential water heater removal surcharge are common. If existing components are outdated, upgrades like a larger electrical panel, copper piping, or upgraded venting may be necessary. Additional costs may include expansion tanks, anti-scald devices, new shutoff valves, and incidental labor for tight crawl spaces or uneven floors.

Ways To Save On Replacement

Get multiple written estimates from licensed plumbers or HVAC contractors to compare pricing and scope.
Ask about package pricing that includes removal, installation, and disposal of the old unit.
Evaluate energy efficiency versus upfront cost; higher efficiency models save on operating costs over time.
Check rebates and financing options, including manufacturer rebates, federal tax credits, or utility company programs.
Plan for future needs such as family size and peak hot water demand to avoid undersizing or oversizing the unit.

Choosing A Qualified Installer

Professional installation is critical for safety and performance. When selecting an installer, homeowners should verify licensing and insurance, request proof of certifications (such as Gas Safe or similar local credentials), and review customer references. Request a detailed written estimate that itemizes the unit cost, labor, permits, and any extras. Confirm the installer’s readiness to handle code-compliant venting, electrical adjustments, and proper water heater alignment with existing plumbing. A reputable contractor will also provide a clear warranty on both the equipment and installation work.
