What affects cost?

Many factors affect the cost of a tank water heater installation, such as the:

  • Efficiency of the water heater: The higher the unit's EF (Energy Factor), the greater the initial investment. A gas water heater in San Antonio should have an EF of 0.50-0.80.
  • Size of the water heater. Water heaters are sized by the number of gallons a full tank can hold. The larger the tank size, the more expensive the unit.
  • Code Requirements. We install the water heater to meet all code requirements.
  • Company you hire for the installation. Hire high-quality technicians even if the up-front investment is more. Choosing one will usually save you money in the long run because you won't need to pay for repeat work.
