Does Water Heater Use Natural Gas: Find Out!


Debarghya Roy

Natural gas is a popular fuel source for water heaters. Does a water heater use natural gas? Yes! It’s frequently used in residential and commercial buildings.

Tankless water heaters are becoming popular too. They don’t need a storage tank, and the amount of natural gas they use depends on factors like flow rate and temperature rise.

Traditional water heaters with a storage tank also use natural gas. The size of the tank affects how much natural gas is required to heat the water. For instance, a 40- or 50-gallon tank will use more gas than a smaller one.

Does a tankless water heater use electricity? Not to heat the water, but it may need electricity for other functions like ignition and controls. But traditional storage tank water heaters might need both gas and electricity to run.

Pro Tip:¬†Choose your water heater wisely! Consider factors like price, efficiency, recovery rate, and installation costs. Even though it’s not the most exciting topic, understanding the basics will make you the provider of hot showers!

Key Notes


  • Yes, water heaters can use natural gas as a fuel source.
  • Natural gas water heaters are popular because they are efficient and costeffective.
  • Natural gas water heaters can provide a continuous supply of hot water.
  • It is important to properly maintain and service natural gas water heaters to ensure safety and efficiency.
  • Natural gas water heaters may require professional installation and should be vented properly to prevent carbon monoxide buildup.
  • It is recommended to consider the size and capacity of the water heater based on the household’s hot water needs.
  • Natural gas water heaters can be a good option for homeowners looking to save on energy costs and reduce their carbon footprint.

Understanding the Basics of Water Heaters

Water heaters are essential for daily life – they provide us with hot water for bathing and washing dishes. To understand them better, let’s look at 3 key points:

  1. Fuel source: Natural gas or electricity. Natural gas has a burner to heat the water, while electric models have heating rods. Each has its own advantages.
  2. Types: Storage tanks store heated water. Tankless models heat on-demand using a heat exchanger. They save space and never run out of hot water.
  3. Efficiency: Energy Factor (EF) rating measures how efficiently the heater converts energy into hot water. Higher EF ratings mean better efficiency & cost savings.

Gas-powered water heaters need access to a gas line & proper ventilation. Electric-powered ones need sufficient electrical supply.

Now for some unique details:

Did you know tankless models have no standby heat loss? Unlike storage tanks, they only heat water when needed. This eliminates energy waste & offers instant hot water.

Different Types of Water Heaters

Water heaters come in various types. Each has its own advantages and functions. Let’s explore them! Here’s a table:

TypeDescriptionPros
Storage TankStores & heats large volume of water for future use.High hot water supply & multiple uses
TanklessInstantly heats water as it passes through heating coils.Energy-efficient & saves space
Heat PumpTransfers heat from air/ground to warm water & save energy.Environmentally friendly & energy-saving
SolarUses solar panels to capture sunlight & heat water.Renewable energy source
CondensingUtilizes exhaust gases to preheat cold water.More efficient than traditional gas models

There are other types too: hybrid, indirect, point-of-use. These cater to specific needs.

Tankless water heaters are ideal for limited spaces. Storage tank models offer large hot water supply but take time to recover after heavy usage.

Before buying, consider factors like household size, hot water needs, energy efficiency, installation costs & fuel source availability. This way you can make an informed decision & get the best water heater for your home.

Does a Water Heater Use Natural Gas?

Water heaters often use natural gas to swiftly and effectively heat water. They use either a pilot light or an electronic ignition system, which sparks a burner to heat the water. Tankless water heaters are becoming popular as they heat water when needed, saving energy.

A 40-gallon tank usually requires around 40,000 BTUs of natural gas each hour, and a 50-gallon tank needs around 50,000 BTUs per hour.

These tankless heaters provide hot water on demand, but still require a power source to heat the water. Natural gas is the usual choice instead of electricity or oil. The units have a heat exchanger that transfers the heat from burning natural gas to the cold water passing through.

Using natural gas has many benefits. It’s supplied through a dedicated gas line and is affordable compared to electricity or other fuel options. This versatile option provides enough hot water for households of all sizes and comes in various models with diverse heating capacities.

Power outages can be problematic for tankless water heaters as they need electricity for their ignition system. Storage tank models can still give hot water if there is preheated water inside.

Pro Tip: Look into factors such as the recovery rate (how fast it can heat up new cold water), cost efficiency of different models, and the size that suits your household’s hot water needs before installing or upgrading your water heater.

Efficiency & cost considerations: While your water heater is active, it’s also making a dent in your wallet.

Efficiency and Cost Considerations

To note, tankless water heaters provide hot water on demand. They use less energy since they only heat water when needed. On the other hand, storage tank water heaters constantly keep hot water ready even when not in use, thus costing more.

So, before deciding which one to get, think about the size of your household and your hot water needs. And know this: using a natural gas water heater can make your gas bill like a scalding shower!

How Much Natural Gas Does a Water Heater Use?

A water heater’s natural gas usage depends on the size of the tank and the demand for hot water. The following table shows the average natural gas consumption for different types and sizes of water heaters:

Water Heater TypeGallonsBTU Input (kW)Energy Factor (EF)
Storage Tank4040,000 (11.7)0.62 – 0.64
Storage Tank5040,000 (11.7)0.58 – 0.60
TanklessVaries0.82 – 0.96

Tankless water heaters use an open flame and a heat exchanger to quickly heat cold water to the required temperature. This is more energy-efficient than storage tank models.

Pro Tip: To save on energy costs and maximize efficiency, consider getting a tankless water heater if your household has high hot water needs or if you prefer energy efficiency.

Surprising Fact: Natural gas water heaters still need electricity to ignite their flames.

Understanding Electricity Usage in Natural Gas Water Heaters

Natural gas water heaters are a common way to get hot water in homes. To use them efficiently and cost-effectively, it’s important to understand their electricity usage.

Here are some key points about electricity usage in natural gas water heaters:

  • How much natural gas do they consume? It varies based on the size and model.
  • Do they use electricity too? Yes.
  • How much electricity do they use? It depends on the model and features.
  • How do they combine gas and electricity? Gas is used to heat the water, while electricity powers components such as the ignition system or control panel.

Note that natural gas is the main fuel source, but electricity is needed for components like the ignition system or control panel.

To make the most of your natural gas water heater, here are some tips:

  1. Choose a high-efficiency model with high Energy Factor (EF) ratings.
  2. Insulate your hot water tank and pipes to minimize heat loss.
  3. Consider a tankless water heater to save energy.
  4. Use hot water responsibly to reduce energy consumption.

Follow these tips to get optimal performance and save electricity. Make sure to read the manufacturer’s guidelines and take safety precautions when dealing with gas or electrical components.
