A tankless water heater, also known as an on-demand water heater or instantaneous water heater, is a type of water heating system that heats water directly as it flows through the unit, without the need for a storage tank. Unlike traditional tank water heaters, which store and continuously heat a reservoir of hot water, tankless water heaters only heat water when there’s a demand for it, hence the term “on-demand.”

Here’s how a tankless water heater works:

  • Water Flow: When hot water is needed, cold water flows into the tankless water heater unit through the inlet pipe.
  • Heating Element Activation: Inside the unit, either a gas burner or an electric heating element is activated to heat the water as it passes through.
  • Heat Exchange: The cold water flows through a heat exchanger, where it is rapidly heated to the desired temperature by the burner or heating element.
  • Output: The heated water then exits the unit through the outlet pipe and is delivered directly to the faucet, shower, or appliance that requires hot water.
  • Continuous Flow: Tankless water heaters provide a continuous supply of hot water, as they heat water on demand. This means that there is no need to wait for a storage tank to refill and reheat, and there’s no risk of running out of hot water during periods of high demand.

Tankless water heaters come in both gas-fired and electric models, each with its own set of advantages and considerations. Gas-powered units tend to have higher flow rates and are better suited for larger households with higher hot water demand, while electric units are generally more compact and easier to install but may have limitations in terms of flow rate and capacity.

Tankless water heaters offer several benefits, including energy efficiency, space savings, and a continuous supply of hot water. Murphy and Son’s brings you quality, affordable installation for tankless water heaters. Call us to get a quote today.

Tankless Water Heater INSTALLATION

As plumbers in Laguna Niguel, we offer hear from homeowners that are searching for ways to lower their utility bills. What you may not know, however, is that well over 16 percent of your home’s electric bill comes from heating your water. This is more than the total amount it takes to run all the other appliances in your home combined. Therefore, you may wish to speak to a plumber about replacing your traditional water heater with a tankless water heater installation. This energy-saving option is a particularly good choice if your hot water usage is somewhat high due to multiple family members taking daily showers or if you must regularly do a significant amount of laundry. Below are some of the major differences between tankless water heaters and traditional units.



Also referred to as an “instantaneous” or “on demand” water heater, a tankless unit generates hot water on an as-needed basis. The primary difference between a tankless hot water heater and a traditional unit is that conventional units keep one tank of hot water on standby, thus using more electricity and increasing your risk of flooding if something goes wrong with the tank.

Tankless units, on the other hand, provide hot water at the time it is needed. Water heaters of this kind run on gas or electricity, with gas powered units capable of producing two to five gallons of hot water in one minute. You can even have have a tankless hot water heater installation done several times in your dwelling if there is a substantial demand for hot water in your home. You may also choose to invest in a tankless unit for a specific appliance, such as a washing machine or dishwasher. In addition, certain models come with their own thermostats for precise temperature control. These are all options that are not possible with traditional units.

Tankless water heaters, also known as on-demand water heaters, offer several benefits compared to traditional tank water heaters:

Energy Efficiency: Tankless water heaters heat water only when it’s needed, eliminating the standby energy losses associated with traditional tank heaters, which constantly keep a reservoir of water hot. This efficiency can result in lower energy bills.

Continuous Hot Water: Tankless heaters provide a continuous supply of hot water, as they heat water on demand. This means you won’t run out of hot water during long showers or while running multiple appliances simultaneously.

Space Saving: Tankless water heaters are typically much smaller than traditional tank heaters, which can free up valuable space in your home, especially if space is limited.

Longer Lifespan: Tankless water heaters generally have a longer lifespan than traditional tank heaters. While tank heaters typically last around 10-15 years, tankless heaters can last up to 20 years or more with proper maintenance.

Reduced Risk of Water Damage: Because tankless water heaters don’t store water, there’s no risk of leaks or flooding due to a ruptured tank. This can help prevent costly water damage in your home.

Customizable Temperature: Tankless water heaters often allow for precise temperature control, allowing you to set the temperature to your preference more accurately than with traditional tank heaters.

Less Environmental Impact: Due to their energy efficiency, tankless water heaters generally have a smaller carbon footprint compared to traditional tank heaters. This can be beneficial for environmentally conscious homeowners.

Reduced Risk of Legionella Bacteria Growth: Legionella bacteria, which can cause Legionnaires’ disease, can grow in the warm water of traditional tank heaters. Since tankless heaters don’t store water, there’s a reduced risk of bacterial growth.

While there is an initial investment in getting a tankless water heater installed, the benefit of savings far surpasses the investment.
