When it comes to heating your home in Derry, choosing the right system can have a big impact on comfort, energy bills, and your carbon footprint. With growing interest in renewable energy and changing government regulations, more homeowners are now asking:
“Should I stick with a gas boiler or switch to an electric heat pump?”
At EMD Plumbing & Heating, we install and service both systems and are here to help you understand the key differences so you can make the best decision for your home and budget.
What’s the Difference?
Gas Boilers burn natural gas to heat water, which is then circulated through radiators and taps. They’re a traditional, proven solution and still found in the majority of UK homes.
Electric Heat Pumps, on the other hand, extract heat from the air (air source) or the ground (ground source) and use it to heat your home and hot water. They run on electricity and are often considered a greener option.
Pros and Cons of Gas Boilers
Advantages:
• Lower upfront cost – Generally cheaper to install than heat pumps.
• Quick heating – Heats water and radiators fast, ideal for colder months.
• Well-suited to older homes – Works well with traditional radiator systems.
Drawbacks:
• Less eco-friendly – Burns fossil fuels, contributing to carbon emissions.
• Gas prices are volatile – Running costs can fluctuate with the market.
• Will eventually be phased out – The UK government aims to stop installing new gas boilers in most homes by 2035.
Pros and Cons of Electric Heat Pumps
Advantages:
• Energy efficient – Can be up to 300% more efficient than gas boilers.
• Lower carbon footprint – Especially if powered by green electricity.
• Eligible for government grants – Like the Boiler Upgrade Scheme.
Drawbacks:
• Higher installation cost – Especially for ground source heat pumps.
• Works best in well-insulated homes – May not be ideal for older properties without upgrades.
• Slower to heat – Operates at a lower temperature than gas boilers, so may need larger radiators or underfloor heating.
What About Running Costs?
The cost difference depends on:
• Gas vs electricity prices
• Your home’s insulation level
• The efficiency of your existing system
In general:
• Gas boilers may be cheaper day-to-day for now.
• Heat pumps can save more long-term—especially with government incentives and rising gas prices.
So, Which Is Best for You?
There’s no one-size-fits-all answer. Here’s a simple breakdown:
Home Type Best Option
Older home, poor insulation Gas boiler (short term)
New build or recently upgraded Heat pump
Planning long-term savings Heat pump
On a tighter budget Gas boiler (initially)
