If you're a homeowner in Los Angeles, chances are you're always looking for ways to save energy, lower your utility bills, and make your home more efficient. One of the smartest upgrades you can consider is switching to a tankless water heater. More and more homeowners are ditching traditional water heaters and turning to tankless models for their efficiency, convenience, and long-term benefits.
In this blog, we’re diving deep into everything you need to know about tankless water heater installation in Los Angeles. From how these systems work to why they’re a great fit for Southern California homes, we’ll walk you through the benefits, installation process, costs, and why working with professionals like Derks Plumbing makes all the difference.
What Is a Tankless Water Heater?
A tankless water heater, sometimes called an on-demand water heater, is exactly what it sounds like—it heats water only when you need it. Unlike traditional systems that store hot water in a tank and constantly keep it heated, tankless units only kick into gear when you turn on the tap. That means no energy is wasted heating water you’re not using.
These systems are compact and are usually mounted on a wall, freeing up space in your garage or utility room. They’re designed to provide a steady supply of hot water without the limits of a storage tank. So whether you’re taking back-to-back showers or running the dishwasher after laundry, you won’t run out of hot water with the right setup.
Why Go Tankless in Los Angeles?
Los Angeles is known for its warm climate, rising energy costs, and eco-conscious homeowners. That makes this city the perfect place to install a tankless water heater. Here’s why tankless systems are especially ideal for LA residents:
- Energy Efficiency: Southern California's utility rates can be high. Tankless water heaters are significantly more efficient than traditional models, which means you’ll see savings on your gas or electric bills almost right away.
- Compact Design: Homes in Los Angeles, especially in urban areas, often don’t have a lot of extra space. Tankless units are wall-mounted and take up far less room than bulky tanks.
- Endless Hot Water: You’ll never again have to schedule showers or stagger laundry loads to avoid running out of hot water. A properly sized tankless heater delivers continuous hot water when you need it.
- Environmentally Friendly: Reducing energy consumption isn’t just good for your wallet—it’s good for the planet. A tankless water heater lowers your carbon footprint and contributes to a more sustainable home.
- Increased Home Value: Installing energy-efficient appliances is a selling point for many homebuyers. A tankless water heater can increase your home’s marketability and value.
How Does Installation Work?
Installing a tankless water heater is more involved than simply replacing an old water tank. It requires careful planning, proper sizing, and knowledge of local plumbing and building codes. Here’s a simplified overview of what the installation process looks like:
- Assessment and Sizing: First, a professional will assess your home’s hot water needs. The right size unit depends on the number of people in your household, how many bathrooms you have, and what appliances need hot water.
- Location and Mounting: Tankless units are usually installed on the wall, either inside or outside your home. A professional plumber will choose a spot that’s convenient and meets code requirements.
- Gas or Electric Upgrades: Depending on whether you choose a gas or electric model, your home may need upgrades to the gas line or electrical panel. This is one of the reasons why DIY installation isn’t recommended—these steps require permits and inspections.
- Ventilation: Gas models need proper venting to safely expel exhaust. Your plumber will install a venting system to meet safety standards.
- Water and Power Hookups: Once the unit is in place, it’s connected to your home’s water supply and power source. The plumber will also ensure there’s a proper drainage system for condensation if required.
- Testing and Inspection: After installation, your plumber will test the system to make sure everything is working smoothly. In some areas, a final inspection from the city may be required to meet code compliance.
How Much Does It Cost to Install a Tankless Water Heater in Los Angeles?
The cost of tankless water heater installation in Los Angeles varies depending on several factors, including the brand and size of the unit, the complexity of the installation, and whether your home needs upgrades to accommodate the new system.
On average, the total cost—including the unit and labor—can range from $2,000 to $4,500. While that’s more than a traditional water heater upfront, the long-term savings in energy bills and the longer lifespan of the system (often 20 years or more) make it a smart investment.
Also, keep in mind that certain models may qualify for rebates or incentives from local utility companies or government programs. A professional plumber can help you navigate these savings.
Gas vs. Electric Tankless Water Heaters
If you’re considering going tankless, one important decision is whether to choose a gas or electric model. Both have their benefits, but your home’s existing setup and your budget may determine which is best.
Gas models typically deliver higher flow rates, making them ideal for larger households or homes with high water demands. However, they may require more installation work, especially if you need to upgrade your gas line or install venting.
Electric models are easier to install and often less expensive up front, but they may not be as powerful, especially if you live in a home with multiple bathrooms. In areas where natural gas is cheap and accessible—like Los Angeles—gas tankless heaters are often the more popular choice.
Common Questions About Tankless Water Heaters
Do tankless water heaters really never run out of hot water?
Yes, as long as the unit is properly sized for your household’s needs. If the demand exceeds the unit’s capacity, it might struggle to keep up, but for most homes, this isn’t an issue.
Can I install a tankless water heater myself?
It’s not recommended. Installation requires knowledge of plumbing, gas, and electrical systems, as well as local building codes. Improper installation can lead to safety hazards and may void your warranty.
How long do tankless water heaters last?
On average, a tankless water heater lasts 20 years or more with proper maintenance, compared to 10–15 years for a traditional tank system.
Is maintenance required?
Yes. It’s important to flush the system annually to prevent mineral buildup, especially in areas with hard water like Los Angeles. A professional plumber can perform routine maintenance to keep your system running efficiently.
Why Professional Installation Matters
Tankless water heaters are advanced systems that need to be installed correctly to work at their best. Hiring a licensed and experienced plumber ensures that your system is properly sized, safely installed, and meets all city and state code requirements.
A professional will also walk you through the maintenance process, show you how to use your new unit, and help you register your warranty. It’s peace of mind that your investment is protected and your hot water supply is reliable.
