Factors Affecting the Cost of a Tankless Water Heater Installation
1. Type of Tankless Water Heater
There are two main types of tankless water heaters:
- Gas Tankless Water Heaters ($1,000 – $3,500 installed): Require a gas line and proper venting.
- Electric Tankless Water Heaters ($800 – $2,500 installed): Easier to install but may require an electrical upgrade.
2. Size and Flow Rate
Larger households require higher-capacity units to meet hot water demand. The cost increases with higher GPM (gallons per minute) ratings.
3. Installation Complexity
If your home requires significant modifications, such as installing new gas lines or upgrading your electrical panel, installation costs will rise.
4. Brand and Quality
Top brands like Rinnai, Navien, and Rheem may have a higher upfront cost but offer better durability and warranties.
5. Location of Installation
If the heater is installed far from plumbing lines or requires wall modifications, labor costs will increase.
Additional Costs to Consider
- Maintenance & Repairs: Regular descaling and servicing may cost around $100 – $300 per year.
- Water Softener Installation: If you have hard water, a water softener ($500 – $2,500) may be necessary to prolong the heater’s lifespan.
- Energy Efficiency Savings: While the initial cost is high, a tankless water heater can reduce energy bills by 8% – 34%.
Is a Tankless Water Heater Worth the Cost?
A tankless water heater is a smart investment for homeowners looking for long-term energy savings and continuous hot water. While the upfront cost is higher than traditional water heaters, the efficiency, longevity (up to 20 years), and space-saving design make it a valuable upgrade.
