How To Convert Gas Water Heater To Electric?

The decision to convert gas water heater to electric one is not just a matter of preference, but also of environmental consciousness, safety, and financial considerations. Gas and electric water heaters, while serving the same primary function, operate on vastly different mechanisms, each with its advantages and limitations. As the world tilts towards more sustainable and eco-friendly choices, many homeowners are exploring the feasibility of such a conversion. Whether motivated by the rising costs of natural gas, concerns about carbon footprints, or the allure of newer electric heater efficiencies, understanding the conversion process is crucial. This guide delves into the meticulous steps involved, weighing the pros and cons, and providing homeowners with a comprehensive overview to make informed decisions.

Preparation and Removal

Safety First 

Prioritizing safety is the cornerstone of any major appliance modification. Before you begin the process of converting your water heater, it’s imperative to shut off both the gas and water supplies. This ensures that the work environment remains hazard-free. The next step is to purge the gas line, ensuring that there’s no residual gas that could lead to potential dangers. 

Given the intricacies and potential hazards associated with gas lines, it’s highly recommended to have a professional handle the disconnection process. Their expertise will guarantee a safe and thorough disconnect, eliminating potential risks such as gas leaks or combustion hazards. Remember, a small investment in a professional service at this stage can safeguard against potentially costly or harmful mistakes.

Remove the Gas Burner Assembly 

The gas burner is a vital component in a gas-powered water heater. It serves as the primary source of heat, igniting the gas to produce the flame that heats the water. The removal process starts with carefully disconnecting the gas line, ensuring there’s no gas escape during the procedure. The burner assembly itself can be intricately connected and might be fastened securely to the base of the water heater. 

As you begin the detachment process, make sure you have the appropriate tools on hand and follow the manufacturer’s guidelines, if available. Once the burner is out, the vent pipe that channels combustion gases out of the home should also be disconnected. This pipe should be sealed effectively afterward to prevent any inadvertent gas leaks or drafts.

Sealing the Ventilation System 

With the burner and associated gas components removed, attention should shift to the ventilation system, which is rendered redundant post-conversion. There are multiple methods to address this now-defunct system. A simple closure involves using a sturdy wall or panel to block off the vent. This method is relatively straightforward and can often be tackled as a DIY project, using basic tools and materials. 

However, for homeowners aiming to reclaim space or remove an outdated chimney structure, the process becomes more complex. This task demands more advanced carpentry and masonry skills. It involves dismantling the existing structure, ensuring no structural damage, and then repurposing or sealing the space. While this method offers the reward of additional square footage, it requires careful planning and execution.

Installation and Considerations

Install the Electric Heating Element 

Transitioning to electric means introducing an electric heating element into the water heater. First, the heater’s tank might need modification. If it doesn’t come with a pre-existing hole suitable for the new element, you’ll need to create one. Precision is essential here to ensure a snug fit and to prevent potential leaks.

Once ready, the heating element can be introduced. It’s critical that the tank’s interior is devoid of moisture at this stage. Any presence of water during the installation can lead to electric hazards or malfunctions. The heating element acts as the primary source of heat in an electric setup, using electricity to generate heat that’s then transferred to the water. Ensure that the element is securely fastened, and all seals are watertight to prevent any future issues.

Wiring and Electrical Connections 

The realm of electrical work is intricate, demanding a meticulous approach. As you transition your heater, it’ll require a connection to your home’s electrical grid. Most electric water heaters demand a dedicated circuit due to their power consumption. Setting this up might involve laying new wires, setting up circuit breakers, and ensuring that the setup meets local electrical codes.

Because of the potential risks and complexities associated with electrical installations, consulting an electrician is more than just good advice it’s a recommended safety measure. An expert can ascertain that connections are not only secure but also insulated against potential failures. Their expertise ensures your new electric water heater operates efficiently, safely, and in compliance with local regulations.


Set Up the Thermostat and Install the New Heater 

The thermostat plays a pivotal role in an electric water heater, regulating the water’s temperature and ensuring energy efficiency. Installing it close to the heating element ensures optimal temperature detection. Once connected to the electrical circuit, it’s paramount to set it to an appropriate temperature, safeguarding against overheating or energy wastage. Following this, the new electric heater installation begins.

This involves connecting the unit to the intake and outtake pipes, integrating it with the newly established circuit, and crucially, calibrating its pressure release valve. This valve acts as a safety measure, preventing over-pressurization. Given the potential hazards, like the risk of the heater exploding due to incorrect setup, it’s a prudent choice to consider hiring an experienced plumber. Their expertise can guide the installation, ensuring all components function harmoniously.

Cost Considerations 

Financial implications are a pivotal part of the conversion decision. Generally, gas is a more economical medium for heating water. However, this largely depends on fluctuating natural gas prices in your locale. When considering the initial investment, it’s worth noting that gas water heaters usually come with a steeper price tag, often costing $80 to $220 more than their electric counterparts. But this isn’t the sole financial consideration.

The conversion process involves other expenditures like circuit expansion and wiring, typically ranging between $60-100 per hour. These costs can accumulate, so it’s essential to budget accordingly. Furthermore, it’s always beneficial to gather multiple service quotes to get a comprehensive understanding of the potential financial commitment. By weighing these costs against long-term benefits, homeowners can make an informed choice.



The intricate journey from a Convert Gas Water Heater To Electric is one that demands careful consideration, expertise, and a fair amount of investment. Yet, with the right knowledge, tools, and professional guidance, it’s a transition that can lead to long-term benefits both financially and environmentally. Beyond the immediate technicalities, the broader perspective is about aligning one’s home infrastructure with future-forward thinking, embracing technologies and practices that are sustainable and efficient. While the initial stages of conversion might seem daunting, the end result, when executed correctly, promises efficient water heating, potential cost savings over the long run, and a reduced carbon footprint a win for both the homeowner and the environment.
