Continuous Hot Water Without Waiting or Running Out

Tankless Water Heater Installation in Tarzana for homes that have outgrown storage tank capacity

ER Plumbing Solutions installs tankless water heaters for homeowners in Tarzana who need a system that delivers hot water on demand without the limitations of a storage tank. You notice the difference when multiple showers run at the same time and the water stays hot, or when you no longer hear a tank cycling on and off throughout the day. These systems heat water only when you turn on a faucet or appliance, which removes the need to store and constantly reheat gallons of water.


Tankless water heaters work well in homes where space is limited, energy bills are a concern, or hot water usage happens in bursts throughout the day. We start by evaluating your home's peak water demand, which includes how many fixtures might run simultaneously and what temperature rise is needed based on incoming water temperature. Once we determine the right unit size, we install the system on a wall, connect it to your gas or electric supply, and set the controls so it activates only when water flows through the unit.



If your current water heater struggles to keep up or you want to reduce energy consumption, we can walk you through what a tankless system would look like in your home.

What Changes After the Installation Is Complete

After we install your tankless water heater, you will notice that hot water arrives at your fixtures without waiting for a tank to refill, and the system does not run out even during high-demand periods. The unit itself takes up far less space than a traditional tank, often mounted on an exterior or interior wall, which frees up floor space in your garage or utility room. You will also see a reduction in standby energy loss since the system only heats water when you call for it, rather than maintaining a full tank at temperature around the clock.


ER Plumbing Solutions ensures the unit is properly sized for your household so that it meets your flow rate needs without lag. We also configure the temperature settings and test all connections to confirm the system responds correctly when you open a tap. The installation includes venting for gas units or electrical upgrades for electric models, depending on what your home requires and what the manufacturer specifies.



Tankless systems do require occasional descaling, especially in areas with hard water, to prevent mineral buildup inside the heat exchanger. We explain what maintenance intervals make sense for your water quality and how to recognize when the unit needs service. This system does not include a storage reserve, so if you lose power or gas supply, hot water stops until service is restored.

Questions About Tankless Water Heater Installation

Homeowners in Tarzana often ask how tankless systems differ in practice from the tank-style heaters they are replacing, and what to expect during and after installation.

How long does a tankless water heater installation take?

Most installations are completed in four to six hours, depending on whether gas lines or electrical circuits need modification and whether venting routes are straightforward.

What size tankless unit do I need for my home?

We calculate the required flow rate by adding up the gallons per minute used by fixtures that might run simultaneously, then match that total to a unit that can handle the demand without dropping temperature.

Why does the water take a moment to get hot even with a tankless system?

The unit heats water instantly once flow is detected, but the hot water still has to travel through your home's piping from the heater location to the fixture, which creates a brief delay similar to any other system.

Can a tankless water heater work during a power outage?

Gas tankless units require electricity to operate the ignition and control board, so they will not function during an outage unless you have a backup power source.

How often does a tankless water heater need maintenance in Tarzana?

We recommend annual flushing to remove mineral deposits, especially if your water hardness is above moderate levels, to keep the heat exchanger operating efficiently.
