What Is a Tankless Water Heater?
Unlike traditional storage water heaters, tankless water heaters (also known as on-demand water heaters) heat water only when needed. That means no bulky tank, no standby heat loss, and nearly instant hot water when you turn on the tap.
Key Advantages:
- Endless hot water (great for large families)
- Energy efficiency (up to 34% more efficient than tank models – per U.S. DOE)
- Space-saving design
- Longer lifespan (often 20+ years with proper maintenance)
How Does Tankless Water Heater Installation Work?
Water heater tankless installation requires both plumbing and electrical/gas work, making it a job best left to professionals.
Here’s an overview of the steps involved:
1. Assessment & Planning
A technician assesses your hot water needs, the existing plumbing layout, and the availability of utilities (gas or electric).
2. Removing the Old Water Heater
If you’re upgrading, the old tank-style water heater is safely disconnected and removed.
3. Installing the New Unit
- Mounting the tankless unit on the wall
- Connecting water lines, gas lines (if applicable), and venting systems
- Adjusting the gas supply or upgrading your electric panel if necessary
4. Testing & Final Inspection
The system is tested for flow rate, temperature accuracy, and safe operation. Local codes may also require a final inspection.
