When it comes to providing hot water for your home, tankless water heaters have gained immense popularity for their energy efficiency and space-saving design. However, there are two main types to choose from: electric and gas tankless water heaters. In this article, we’ll break down the key differences between these two options to help you make an informed decision for your home’s hot water needs.

How Tankless Water Heaters Work
Before diving into the electric vs. gas debate, let’s first understand how tankless water heaters function. Unlike traditional storage water heaters, which store and heat a large amount of water continuously, tankless water heaters only heat water as you need it. They use either electric or gas-powered heating elements to achieve this, but the process varies significantly between the two types.
Electric Tankless Water Heaters
- Heating Element
Electric tankless water heaters rely on electrical resistance heating elements to heat the water. When you turn on a hot water tap, cold water flows into the unit, and an electric heating element instantly heats the water to the desired temperature.
- Installation and Size
One of the advantages of electric tankless water heaters is their compact size and ease of installation. They can be mounted on walls or placed in small spaces, making them suitable for homes with limited room for a bulky water heater.
Electric tankless water heaters are highly efficient since they don’t have standby heat loss. Standby heat loss occurs in traditional storage water heaters, where the water in the tank constantly loses heat, even when not in use. With electric tankless units, you only heat the water you need, reducing energy waste.
- Energy Source
Electric tankless water heaters require a reliable source of electricity to function. They are ideal for homes with a consistent electrical supply and are suitable for smaller households with moderate hot water needs.
Gas Tankless Water Heaters
- Heating Element
Gas tankless water heaters, on the other hand, utilize a gas burner to heat the water. When hot water is needed, the gas burner ignites, heating a coil through which water flows, thereby providing instant hot water.
- Installation and Size
Gas tankless water heaters tend to be larger and more complex than their electric counterparts. They require proper venting to expel combustion gases, which can make installation more involved. Due to their size and venting requirements, they may need a dedicated space in your home.
Gas tankless water heaters are known for their high efficiency, similar to electric models. They do not have the standby heat loss issue seen in traditional water heaters, making them an excellent choice for households looking to reduce energy consumption.
- Energy Source
Gas tankless water heaters rely on a natural gas or propane supply. This means they are ideal for homes with access to a gas line but may not be suitable for areas with limited or no gas infrastructure.
Comparing Electric and Gas Tankless Water Heaters
Now that we’ve outlined the fundamental differences between electric and gas tankless water heaters, let’s delve into a more detailed comparison to help you decide which option is better suited to your needs.
- Cost of Installation
Electric: Electric tankless water heaters are generally more affordable to install. They don’t require gas lines or complex venting systems, which can reduce installation costs.
Gas: Gas tankless water heaters tend to have a higher upfront installation cost due to the need for gas lines, venting, and proper ventilation. However, they may offer long-term cost savings on energy bills.
- Energy Efficiency
Electric: Electric tankless water heaters are highly efficient, but the cost of electricity can be higher than gas in some areas, potentially impacting operating costs.
Gas: Gas tankless water heaters are also highly efficient, and if you have access to affordable natural gas or propane, they may have lower operating costs than electric models.
- Hot Water Output
Electric: Electric tankless water heaters may have a slightly lower flow rate compared to gas models. This means they may struggle to provide hot water for multiple high-demand appliances simultaneously.
Gas: Gas tankless water heaters typically have a higher flow rate, making them better suited for larger households with multiple hot water needs simultaneously.
- Space Requirements
Electric: Electric tankless water heaters are compact and can be installed in smaller spaces, making them ideal for homes with limited room for a water heater.
Gas: Gas tankless water heaters are bulkier and require adequate space for installation, including proper venting.
- Environmental Impact
Electric: Electric tankless water heaters produce no greenhouse gas emissions on-site, making them an environmentally friendly option if your electricity comes from clean energy sources.
Gas: Gas tankless water heaters emit carbon dioxide and other greenhouse gases during operation. Their environmental impact depends on the source of the gas and its carbon footprint.
Electric: Electric tankless water heaters generally require less maintenance, as they have fewer complex components and no combustion process to maintain.
Gas: Gas tankless water heaters may require more regular maintenance due to the gas burner and combustion system. This can add to the overall cost of ownership.
- Availability of Energy Source
Electric: Electric tankless water heaters can be used in most areas since electricity is widely available. However, they may not be ideal for areas with frequent power outages.
Gas: Gas tankless water heaters require access to a natural gas or propane supply. They may not be suitable for regions without gas infrastructure.
Choosing the Right Option for Your Home
In summary, the choice between an electric and gas tankless water heater depends on several factors, including your budget, energy costs, hot water needs, available space, and environmental considerations.
Electric tankless water heaters are a good fit for:
- Smaller households with lower hot water demands.
- Homes with limited space for a water heater.
- Areas with reliable electricity and potentially lower electricity costs.
- Eco-conscious homeowners looking to minimize their carbon footprint.
Gas tankless water heaters are a better choice for:
- Larger households with higher hot water demands.
- Homes with ample space for a water heater and proper ventilation.
- Areas with access to affordable natural gas or propane.
- Those looking for a high-flow-rate solution for multiple hot water appliances.
It’s essential to conduct a thorough assessment of your specific needs and constraints before making a decision. Additionally, consulting with a professional plumber or HVAC technician, especially those experienced in water heater maintenance and drain cleaning Tulsa, can provide valuable insights and help you determine the most suitable option for your home.
Electric and gas tankless water heaters each offer unique advantages and considerations. Ultimately, the choice between the two comes down to your individual circumstances and priorities. Whether you opt for the compact and cost-effective electric model or the high-flow-rate gas version, both can provide you with a continuous supply of hot water while potentially saving energy and space in your home.
