Electric vs. Gas Water Heaters: How To Choose?

Discover the benefits and disadvantages of each fuel source, as well as newer, more efficient designs of water heaters that might save you money in the long run.


If you have actually had the very same hot water heating system for more than 10 years– the average lifespan– an excellent suggestion would be to think about changing it well before it breaks down and puts you in a jam.


Before you begin going shopping for a new water heating system, you should first decide whether it must be gas or electrically powered. While both types are very the same, there are notable differences in regards to functions and efficiencies in between the two.

The choice in between gas and electrically powered water generally comes down to the type of power currently present in the residence.

Most times, property owners just go with whatever the residence currently has. Nearly every residence has electrical power, and many have both gas and electrical power.


However, if you merely have electrical power, the decision is basic: You require to pick an electrical hot water heater.


Electric powered hot water heating systems might not be the only alternative for rural residents who do not have access to natural gas. They can use a gas water heater if they have propane.


Both gas and electrically powered water heaters are graded by “input,” which is a measurement of just how much gas or electrical power is utilized each hour to warm the water in the tank.


BTUs are utilized to determine gas input, while watts are utilized to determine electrical input.

Electric Gas Water Heater
  • A gas hot water heater’s average input score ranges from roughly 30,000 to 180,000 BTUs, depending upon size. The higher the BTU score, the quicker the device will warm water.

  • The power input of electrical water heaters ranges from around 1,440 to 5,500 watts, and the very same idea uses– the higher the wattage, the quicker the device will warm water.

Gas hot water heater have higher starting prices than equal electrical hot water heater, but they can also be cheaper to operate.

The cost of a hot water heater varies mostly based on how big, efficient, and high quality your hot water heater is. Typically, the higher the cost, the better the system will execute. A gas hot water heating system, on the other hand, will cost more upfront than a comparable-size electrical hot water heating system.


On the other hand, it is generally cheaper to operate a gas hot water heater since the expense of natural gas is lower in a lot of places of the country than the expense of electrical power.


Depending on where you are, you might prefer one over the other. Your month-to-month expenses are what will hurt you in the long run.


While the expense of a hot water heater is important, it must not be your lone deciding issue. Your decision must take into account the expense of performance, operation, and efficiency.

Electric hot water heater (in particular electrical heat pump hot water heater) can have EF ratings that are higher than gas hot water heater.

The energy factor (EF) of a gas or electrical hot water heater is a measurement that compares the volume of hot water produced per day to the volume of fuel consumed.


The more energy efficient the water heater, the higher the EF value. While the efficiency of gas and electrical models is generally equivalent, particularly when comparing models of the very same manufacturer and size, specific kinds of electric-powered models– including heat pump and hybrid heat pump units, as talked about below– have the efficiency edge.


The EF score of a hot water heater can be looked for on the product’s box or in the literature that comes with it. Every new standard water heater should have a bright yellow and black Energy Guide label that reveals the product’s energy factor as well as the following information:


  • The type of fuel the water heater uses.
  • Its estimated annual operating expense.
  • The estimated volume of energy utilized annual (BTUs or watts).
  • If the water heating system satisfies Energy Star requirements for water heating units), an Energy Star brand (.
  • Tank size (in gallons).
  • First-hour score (see below).


You won’t have the ability to see the Energy Guide label if you shop online, but trusted suppliers provide all technical requirements about the models they offer, so you’ll have all the facts you require to make an educated decision.

A number of kinds of gas and electrical hot water heater are more efficient by design.

Neither fuel type guarantees the greatest performance; nevertheless, manufacturers have developed extremely efficient subcategories of water heaters for each type of power source.

Efficient Gas Water Heaters

Energy Efficient Gas Water Heaters

Condensing water heaters recirculate and catch energy that would otherwise be lost in order to improve the total performance of the appliance.


Condensing units capture and recycle hot water vapor, as opposed to normal (non-condensing) gas hot water heaters, which route hot water vapor down a flue and exhaust it out of the house.


Obviously, these systems have downsides and benefits:


  • Condensing water heaters are more pricey than comparable non-condensing systems.
  • Running expenses are lower for condensing hot water heaters.
  • Condensing water heaters have higher first-hour ratings and recovery rates than non-condensing models.
  • A set up gas line is required.
High Efficiency Condensing Water Heaters

Energy Efficient Electric Powered Water Heaters

The heat pump hot water heater is the peak of efficiency in electrical hot water heaters. This water heating system is most suited for usage in warm regions since it draws heat from the air.


Heatpump models are more pricey than non-heat pump ones (about $800 to $2,500 more than a basic electrical system), but they are the most efficient hot water heaters on the marketplace today.


Hybrid heat pump hot water heaters make it possible for the consumer to pick several working modes for various scenarios, hence increasing the product’s efficiency.


Most hybrid heat pump systems, for example, offer a “vacation” mode that decreases operating expenses while no one is at home.


Depending on the system, selecting a hybrid heat pump over a typical water heater can save you as much as 80% on hot water expenses. These products, nevertheless, should be set up in an area of a minimum of 1,000 square feet, so while they appropriate for a big garage, they are not suited for a small utility closet.

Tankless Water Heaters

Energy-efficient Water Heaters Powered by Gas or Electrical energy

Tankless hot water heaters, typically known as “on-demand” or “point-of-use (POU)” hot water heaters, are offered in both gas and electrical models. When an unit or a faucet is switched on, these smaller configurations draw water in through a heating element.


They can be as much as 35% more energy highly effective than basic tank-type hot water heaters since they warm water as you use it. Condensing or non-condensing gas tankless hot water heaters are offered.


They have a limitation on just how much hot water can be pumped out at the same time, so choose the device based upon just how much hot water you’ll require. Due to the fact that they do not hold hot water, recovery and first-hour ratings do not apply (see below).


Rather, tankless hot water heaters are sized based upon their “flow rate,” which is determined in gallons per minute (GPM).

Gas hot water heaters tend to warm up faster.

Gas produces heat quicker than an electric heating element since of its combustion. As a result, the recovery rate and first-hour score (FHR) of gas hot water heaters are higher than those of equivalent electrical systems with the very same manufacturer and tank size.

(You can find these ratings on the unit’s description on the merchant’s or manufacturer’s website).

  • The amount of water that the unit can warm an extra 90 degrees Fahrenheit in time is indicated by the recovery rate, which is determined in gallons per hour (GPH)
  • When the water in the tank is fully heated up, the FHR shows how much hot water the heating system can give up the first hour. The higher the FHR, the more efficient the water heater.

An electrical water heater installation could be a DIY project.

A motivated do-it-yourselfer with fundamental electrical expertise can generally replace an electric hot water heater and reduce installation expenses (about $350 to $450, depending upon the location locations of the country will have differing rates).

Replacing a gas hot water heater, which needs removing and reconnecting a gas line, is a completely different process. Gas lines should be moved throughout installation, and natural gas and propane hot water heaters (other than condensing styles) should be vented to the outside.

This is not a project that the average property owner has the ability to do; rather, it is suggested that the installation be dealt with by an expert.


If a home currently has a gas water heater, a plumbing technician will charge $400 to $550 to remove the old unit and set up the new one, regardless of whether it is a tank or tankless design. However, changing from electrical to gas might cost an extra $1,500 to $2,300 in installation expenses due to the need to run a new gas line and set up venting.


The type of water heater (tank or tankless, for example), instead of the power source, will decide for how long it lasts.


Tank hot water heaters last 10 to 13 years usually for both gas and electrical, whereas tankless devices can live up to 20 years or more. Electric heat pump hot water heaters have a lifespan of 12 to 15 years usually.


Whatever type of water heater you choose, whether gas or electrical, you will get the most useful life out of it if you always follow the manufacturer’s annual service and maintenance schedule.
