Until now, homeowners are still confused about whether to choose an electric boiler or a gas boiler to install in their homes. There is no absolute good or bad answer between the two. It depends on your actual situation, needs and ideas.
In this article, we’ll analyze the difference between gas and electric boilers, so you can make a confident and clear choice.
What Is Gas Boiler?
A gas boiler is a heating system that uses natural gas or propane as fuel to heat water for residential or commercial heating and hot water supply.
1990s-Present: Technological advancements have led to highly efficient and environmentally friendly models. Modern gas boilers feature electronic controls, modulating burners, and advanced materials for heat exchangers.
What Is Electric Boiler?
An electric boiler is a heating system that uses electricity to heat water for central heating and hot water supply in residential or commercial buildings.
1990s-Present: The rise of renewable energy sources and the push for lower carbon emissions have increased the appeal of electric boilers. Modern electric boilers are highly efficient, with advanced electronic controls and compatibility with smart home systems.
What Is The Difference Between Gas Boiler And Electric Boiler?
Efficiency
Gas Boilers: Modern condensing gas boilers are highly efficient, often exceeding 90% efficiency. However, they can lose heat through flue gases.
Electric Boilers: Typically more efficient in converting energy to heat (nearly 100%).
Installation
Gas Boilers: Require a connection to the gas supply, condensate pipe or flue. Initial installation needs to install a gas line.
Electric Boilers: Only electrical connections are required.
Safety
Gas Boilers: Potential risks of gas leaks and carbon monoxide poisoning if not properly maintained.
Electric Boilers: There may be a risk of electric shock due to leakage if the operation is done improperly.
Space-saving
Gas Boilers: Require more space due to the need for gas line. Need a storage tank if using a system or conventional boiler.
Electric Boilers: It’s compact and can fit in smaller spaces. Ideal for apartments or homes with limited space.
Power Output
Gas Boilers: Capable of providing high heat output suitable for larger homes and buildings.
Electric Boilers: Generally less powerful than gas boilers. It may be difficult to meet large hot water demands at the same time, depending on the model and system setup.
Costs
Gas Boilers: Often cheaper to run due to lower gas prices. However, initial installation can be more expensive, especially if you need to install a gas line.
Electric Boilers: Lower installation costs and minimal maintenance. However, high electricity prices result in higher operating costs.
Reliability and Convenience
Gas Boilers: May experience issues related to gas supply interruptions.
Electric Boilers: Dependent on a consistent and reliable electricity supply, which can be an issue during power outages.
Life span
Gas Boilers: 10-15 years
Electric Boilers: 15-25 years
Market Trends
Gas Boilers: Remain popular due to their powerful heating capabilities and established infrastructure, especially in areas with a reliable natural gas supply.
Electric Boilers: Gaining popularity due to the increasing availability of renewable energy, lower maintenance requirements, and ease of installation, particularly in new constructions and areas without a natural gas supply.
Environmental Impact
Gas Boilers: Burns fossil fuels, producing CO2 and other greenhouse gases.
Electric Boilers: Produce no emissions at the point of use, especially beneficial when powered by renewable energy sources.
