Gas Versus Electric Water Heaters

What Is The Difference Between Gas And Electric Water Heaters?

There are several different types of water heaters that use either gas or electricity. Here is a closer look at the different types of water heaters available.

Standard Storage Tank Water Heaters

Most water heaters in North America are either gas or electric storage tanks. These standard tanks range in size and can store anywhere from 20 to 100 gallons of water. The main difference between gas and electric water heaters is the energy used to heat up the water. Gas water heaters burn fuel like natural gas to heat up the water in the tank while electric water heaters use electric resistance coils.

High-Efficiency Storage Tank Water Heaters

There are also high-efficiency storage tank water heaters available in both gas and electric models. These high-efficiency units can save you money on your energy bill over time.

Tankless Water Heaters

A tankless water heater either uses electric coils or gas to heat up water on demand. Tankless water heaters operate by warming up the water as it flows through your home or office. These units tend to be more expensive upfront than traditional tanks; however, they use less energy since water is heated as needed and not kept warm in a storage tank.

Heat Pump Water Heaters

A heat pump is another choice for electric water heating. These efficient yet expensive models heat up your water by pulling in heat from the surrounding air. As a backup, there are electric elements to ensure your water is hot. 

Water Heater Installation Methods

Unless you have a background in plumbing or electrical work, always enlist professional help in order to install any type of water heater. From understanding plumbing codes, obtaining appropriate work permits as well as working with electricity or natural gas, most homeowners and business owners realize that calling an expert is the wisest choice. For standard storage tanks, these installation methods will be completed in the following manner:

Gas Water Heater Installation

  2. Drain the water in the tank
  3. Unscrew the vent pipe from the hood, cut away unit from water lines and remove the old water heater

  5. Solder the new copper pipe-fittings into the water inlet ports

Electric Water Heater Installation

  2. Drain the water from the old tank
  3. Disconnect the electrical wires under the access panel on the unit and the water lines from the old unit
  4. Remove the old water heater
  5. Confirm that the circuit breaker can handle the energy required from the new water heater
  6. Rewire the new water heater
