  • Frequently Asked Questions About Tankless Water Heaters

    Written by ABC Plumbing, Heating, Cooling & Electric

    How does a tankless water heater work?

    Tankless Water HeatersA tankless water heater works on demand so it isn’t using any gas until the  hot water is turned on from the point of use.  The units ABC installs start working at very low pressures to ensure the unit turns on quickly and then will continue to provide hot water heater for as long as you want to use the shower or faucet, etc. Premium tankless water heaters, also called hybrid water heaters, have a buffer tank installed with a pump,  this eliminates the “cold water sandwich” that is common amongst tankless water heaters,  it also allows the hot water to get to the faucet faster.

    What are the advantages of using a tankless water heater?

    The first benefit is endless hot water,  you can literally turn the hot water on at 8am and then shut it off at 9pm and it will still be the same temperature.  They also are more efficient than a typical heater usually this means you save on your gas bill.  Next, all parts of the unit are replaceable unlike a tank type water heater,  which means a much longer life expectancy and better warranties.  Because it doesn't have a large tank of water, it will not flood the basement and takes up no floor space.

    Can a tankless water heater be installed in the same place as the old water heater?

    Yes,  they can be installed almost anywhere because the manufacturing process is completing at the job site it allows greater flexibility for installation location.

    How much does it cost to have a tankless water heater installed?

    This depends on various things throughout the installation process and what exactly you looking for. That is why ABC always sends a licensed technician to the home first, to examine and discuss the options available. We provide you with a guaranteed price in writing before any work begins.
