Tankless water heaters are one of the most impactful energy-efficient home upgrades. Unlike traditional models that reheat stored water, tankless systems heat water on demand—cutting energy waste, saving space, and lowering costs. This guide covers how they work, key benefits, and what to expect during installation.

What Is a Tankless Water Heater?

Unlike conventional water heaters, which store hot water in a large tank, tankless water heaters heat water only when needed. When you turn on a hot water tap, cold water travels through a pipe into the unit, where either a gas burner or electric element heats it instantly. This provides a continuous supply of hot water without the need to store and reheat gallons throughout the day.

Benefits of Tankless Water Heater Installation

1. Endless Hot Water

Tankless systems are ideal for families or homes with high hot water usage. Since water is heated on demand, you won’t run out of hot water during back-to-back showers or laundry cycles.

2. Lower Energy Bills

Tankless units only heat water when needed, reducing energy consumption by 24%–34% compared to conventional storage heaters (according to the U.S. Department of Energy). Over time, this can lead to significant savings on your utility bills.

3. Space-Saving Design

Traditional water heaters, with their bulky tanks, take up valuable floor space. Tankless models are compact and wall-mounted, freeing up space in basements, closets, or utility areas.

4. Longer Lifespan

While conventional water heaters typically last 8 to 12 years, tankless water heaters can last up to 20 years with proper maintenance. This longevity makes them a cost-effective investment over time.

5. Cleaner, Fresher Water

With no storage tank, there’s less risk of rust and scale buildup in your hot water, meaning cleaner water for showers, cooking, and cleaning.

Is a Tankless Water Heater Right for You?

While tankless water heaters offer many benefits, it’s important to determine if they’re the right fit for your home. Consider the following factors:

• Home size and hot water demand: Larger households may need multiple units to meet simultaneous hot water needs.
• Fuel type: Tankless water heaters can be powered by natural gas, propane, or electricity. Gas models often require venting, while electric units need proper circuit capacity.
• Installation costs: Tankless systems can cost more upfront than traditional units. However, energy savings and lifespan often offset the initial investment.

What to Expect During Installation

Tankless water heater installation typically involves a few key steps:

1. Assessment and Sizing: A professional technician evaluates your home’s water usage and recommends the right size and model.
2. Removal of Old Unit: The old tank is safely disconnected and removed if replacing an existing water heater.
3. Upgrades and Connections: Depending on the unit, installers may upgrade gas lines, electrical wiring, or ventilation systems to meet requirements.
4. Mounting and Testing: The tankless heater is mounted to the wall, connected to plumbing and power, and thoroughly tested for performance and safety.

A licensed plumber or HVAC technician should always install to ensure compliance with local codes and manufacturer warranties.

Maintenance Tips for Long-Term Performance

Tankless water heaters need little upkeep, but routine maintenance keeps them efficient and long-lasting. Descale annually, clean the water filter and check for leaks. A professional inspection every year or two can prevent costly repairs.

Why Now Is the Right Time to Upgrade

With energy costs rising and sustainability at the forefront of minds, tankless water heater installation is a smart, efficient upgrade for any home. Whether you’re building a new system or replacing an old one, the long-term savings and performance make it worth the investment—especially with available rebates and incentives.
