Tankless water heaters are much more energy-efficient and have a lifespan that is almost twice as long as a standard water heater with a tank. These cost savings can help make up for the higher initial cost of a tankless model. When you turn off the faucet, the water heater shuts off, which saves energy. Tankless units may use electricity, natural gas, or propane to heat the water.

Although there is no storage tank, it is still important to choose the right size water heater. This depends on the number of appliances or fixtures that you need to run and the flow rate for each, as well as the temperature rise. This is the difference between the water entering the home and the desired temperature. Our plumbers can perform the necessary calculations to ensure that your new water heater meets your family’s demands.


Standard water heaters with a storage tank must constantly run to keep the water in the tank heated. This wastes energy and limits the hot water in your home to the amount of water that can be stored in the tank. Tankless water heaters heat water instantly when you turn on the tap, so you always have hot water.

The benefits of tankless water heaters include:

  • Better energy efficiency
  • Save money on your energy costs
  • A constant supply of hot water
  • Smaller size that takes up less space
  • Longer lifespan
  • Although tankless water heaters offer many advantages, a tankless model may not be the ideal choice for every home.

The drawbacks of on-demand water heaters include:

  • Gas and propane models need stainless steel tubing for venting
  • Higher initial cost
  • Annual service may be required
  • We can help you compare standard tank water heaters and tankless water heaters in Antioch, so you can find the best unit for your hot water needs and your budget.
