If you're a homeowner in Los Angeles, you already know how important it is to have a reliable and efficient water heating system. Traditional water heaters have served many homes for decades, but now, more and more people are making the switch to tankless water heaters. Why? Because they offer convenience, energy efficiency, and long-term savings.
In this guide, we’ll explain everything you need to know about tankless water heater installation in Los Angeles—how it works, its benefits, what to expect during installation, and why hiring professionals like Derks Plumbing Company Inc. is the best choice for your home.
What Is a Tankless Water Heater?
A tankless water heater, sometimes called an on-demand water heater, heats water only when you need it. Unlike traditional water heaters that store and heat gallons of water in a tank around the clock, tankless models provide hot water instantly without storing it. When you turn on the hot water tap, cold water travels through a pipe into the unit, where it’s heated by either a gas burner or electric element.
This smart heating method means you don’t have to wait for the tank to fill or reheat. You get an unlimited supply of hot water—and you save money by not heating water 24/7.
Why Are Los Angeles Homeowners Choosing Tankless Water Heaters?
The climate and lifestyle in Los Angeles make tankless systems especially appealing. Homes in the LA area often have high water usage, especially in multi-person households. Hot showers, washing machines, and dishwashers running throughout the day can take a toll on traditional water heaters.
With a tankless water heater, you won’t run out of hot water no matter how busy your household gets. Plus, they take up less space—a huge benefit in homes where square footage is valuable.
Energy efficiency is also a big factor. In a city that experiences rolling blackouts and rising utility costs, using a system that consumes less power is a smart financial move. Tankless units use about 30–50% less energy than traditional heaters, and that difference adds up over time.
How Long Does a Tankless Water Heater Last?
Another big advantage of going tankless is durability. While traditional tank systems generally last 8 to 12 years, tankless water heaters can last 20 years or more with proper care. That’s almost twice the lifespan, meaning fewer replacements and more value for your investment.
Many modern tankless systems also come with advanced features like Wi-Fi monitoring, temperature control, and even leak detection—all adding convenience and peace of mind for homeowners.
How Is a Tankless Water Heater Installed?
Installing a tankless water heater involves a few important steps, and it’s not usually something homeowners should try to do on their own. The process begins with choosing the right unit for your home. Factors like the number of people in the household, the number of bathrooms, and how often hot water is used throughout the day all help determine the correct size and type of heater you need.
Once you’ve selected a unit, the old water heater is removed and the area is prepped for the new installation. Tankless water heaters require special venting and possibly upgraded gas or electrical lines, depending on whether you choose a gas or electric model. These changes ensure that the system works efficiently and safely.
A licensed plumber, like those at Derks Plumbing, will also make sure the system complies with local building codes and regulations in Los Angeles. Improper installation can lead to poor performance, frequent breakdowns, or even damage to your plumbing system. That’s why hiring an experienced team is crucial.
Gas vs. Electric Tankless Water Heaters: Which One Should You Choose?
There are two main types of tankless water heaters: gas and electric. Each has its pros and cons, and the right one for your home depends on your specific needs and what energy sources are available.
Gas-powered tankless water heaters heat water quickly and are usually better for large households with higher water demands. However, they require proper gas line sizing and venting, which can increase installation costs.
Electric tankless water heaters are more compact and easier to install, especially in smaller homes or apartments. They are often more energy-efficient for homes that don’t use large amounts of hot water all at once. On the downside, they may struggle to supply hot water to multiple fixtures at the same time.
A professional plumber can evaluate your home and recommend the best type based on your budget, water usage, and long-term goals.
Maintenance Tips to Keep Your Tankless Water Heater Running Smoothly
Tankless water heaters are low-maintenance, but they still need occasional care to stay in top condition. In Los Angeles, hard water is a common issue, and mineral buildup can affect your system’s efficiency over time.
Flushing the system once a year can help remove calcium and other deposits. You may also want to install a water softener or a pre-filter if your home has particularly hard water. Cleaning the air and water filters regularly can also extend the life of your unit.
Having a professional plumber perform an annual inspection is always a good idea. They’ll check for any issues, clean the system, and ensure everything is running at peak efficiency.
Cost of Tankless Water Heater Installation in Los Angeles
The cost to install a tankless water heater in Los Angeles can vary depending on a few factors:
- Type of unit (gas or electric)
- Size and capacity
- Complexity of installation (new venting or upgraded lines)
- Labor costs
On average, you can expect to pay anywhere from $2,000 to $4,500 for the full installation. While this is higher than a standard tank unit, the energy savings and longer lifespan more than make up for the upfront investment.
Many local and federal programs also offer rebates or tax incentives for energy-efficient home upgrades, which can help reduce the cost even further. Your plumber can help you explore those options during the planning phase.
