Is your current tankless not producing hot water? Or is it only working intermittently and displaying an error code? Whatever your problem happens to be, a highly trained tankless technician will perform a series of tests on the unit to determine the root of the problem and then direct you to the correct course of action. Call 866-405-2378 to schedule an appointment.


The cost of a tankless water heater including the installation will vary depending on a few factors:

  • The size of the unit in GPM (gallons per minute) or its BTU rating.
  • Is the tankless natural gas, liquid propane or electric?
  • Will the unit be installed inside the property or mounted outside on an exterior wall.
  • Residential or commercial.

Besides these factors, the layout of your home will also play a role in determining a complete materials list and ultimately the price of a tankless system. For average size homes, 1 to 3 bathrooms, the cost for a complete installation will usually range between $2000 and $2700, with all of the above information taken into consideration. Larger homes may be higher but there are usually installation options for every house. Also, there are currently buying incentives, such as So Cal Gas Company rebates and Federal tax credits. Call us to have a tankless water heater expert provide you with a free estimate at 866-405-2378.

  • Go Green!!! By eliminating stand-by heat loss, energy consumption is significantly reduced. Because of its on demand functionality, you won’t be heating water when out of the house or sleeping. Also, a tankless water heater will last 2 to 3 times as long as a traditional water heater, meaning less waste in our landfills.

  • Never run out of hot water! A tankless water heater heats water on demand using a heat exchanger and a high power burner system so that you will never run out of hot water. Multiple showers can be taken at the same time along with your laundry load and/or your dish washer without running out of hot water, and these applications can be in use for as long as you need them!

  • Save Money! Because of the technological advances over your conventional water heater, a tankless will only heat water when you need it. It contains a flow sensor that will tell the unit to power on when water is running through it. This means that you are using minimal gas to heat your water, whereas a tank will use gas, 24 hours a day 365 days a year, to maintain a constant temperature. Start saving money today!

  • Huge space saver! Look at your current water heater and imagine a small suitcase in its place. Going tankless will free up this area dramatically allowing for more storage and just a cleaner space. The tankless is mounted on the wall and is approximately 24 x 14 x 10 inches, which will allow for as much as 50 cubic feet of free space!

  • Very long life expectancy! Tankless water heaters have been tried and tested and the technology has been around for over 50 years. They will generally last 20 to 25 years, whereas a conventional tank will last on average 8 to 12 years. That’s 2 to 3 times longer than a tank and makes it an exceptional investment!
