What Is A Gas Boiler?

A gas boiler heats water using natural gas, which is then circulated through your central heating boiler system to warm radiators and supply hot water.

Gas boilers are by far the most common boiler types in UK homes and are exceptionally efficient for properties connected to the mains gas supply.

Pros And Cons Of Gas Boilers

Pros

• Lower running costs than electric options (essential given the UK's unit cost differences between gas and electricity).
• High output, making it ideal for larger homes or properties with higher water usage.
• Quick heating response for both space and water heating.
• Compatible with combi systems and traditional system setups.
• Widespread availability of qualified Gas Safe engineers for installation and repairs.

Cons

• Requires annual servicing for efficiency and safety.
• Not suitable for properties not connected to the gas grid.
• Needs to be located in a suitable position so that the flue can discharge outside of the property.

What Is An Electric Boiler?

An electric boiler uses electrical resistance to heat water, with no need for a flue, making them compact and simple to install in homes without a gas connection.

Pros And Cons Of Electric Boilers

Pros

• Simple to install — no fuel or gas line needed.
• Compact and often quieter than gas boilers.
• Zero on-site emissions.

Cons

• Significantly higher heating costs due to the price of electricity per kWh in the UK.
• Struggles with high hot water demand – not ideal for larger homes.
• Limited lifespan compared to modern gas boilers.
• Not always compatible with existing radiators or pipework.
• Requires a dedicated electrical supply to be extended from the fuse board.
• More susceptible to being adversely affected by deposits in the heating system

Gas Boiler Vs Electric Boiler: Which Is Better For Your Home In The UK

Choosing between a gas boiler and an electric boiler depends largely on your property type, usage, and available fuel connections.

Choose A Gas Boiler If:

• Your home is connected to the gas grid.
• You have a high demand for hot water, such as in multiple bathrooms.
• You want to keep the boiler running costs low.
• You need a reliable, long-term heating solution.
• You want support from certified engineers like those at Maintracts Services Ltd.

Choose An Electric Boiler If:

• Your property doesn’t have access to mains gas.
• You live in a small flat or studio with low heating needs.
• You prefer a simpler installation and have low water usage.
• If it is not possible to discharge a flue externally

So, in most UK scenarios, particularly for family homes, a gas boiler is a more practical and cost-effective option than an electric boiler.

FAQs

1. What’s the main difference between a gas and an electric boiler?

Gas boilers use natural gas to generate heat, while electric boilers rely on electricity. This impacts running costs, heating capacity, and installation requirements.

2. Which type of boiler is better for the environment?

Electric boilers emit no on-site emissions; however, their environmental benefit depends on the greenness of the electricity supply. Gas boilers are improving with more efficient models, but do produce CO₂.

3. Is an electric boiler suitable for large homes in the UK?

Not typically. Electric boilers struggle to meet high hot water demands, making gas boilers a better option for UK homes, particularly for larger properties.

4. Can I install an electric boiler in a home that doesn't have a gas supply?

Yes. Electric boilers are ideal for homes without gas connections, but they may result in higher heating costs in the long term.

5. Are electric boilers easier to maintain?

Yes, they require less frequent maintenance. However, when faults occur, replacement of heating elements can be costly.

6. Which type of boiler has a longer lifespan: gas or electric?

With proper maintenance, gas boilers often outlast electric models, especially in high-demand households.

7. Will gas boilers be banned in the UK?

There is no immediate ban on existing gas boilers. However, from 2025, new builds may face restrictions. For existing homes, replacement and maintenance are still fully supported.

8. Should I switch to an electric boiler in 2025?

Only if your home is unsuitable for gas or you have specific low-demand needs. Otherwise, a modern gas boiler remains the most cost-effective option.
