Electric Boilers vs Gas Boilers: Which Heating System Is Right for Your Dublin Home?

Electric Boilers vs Gas Boilers

Choosing between an electric boiler and a gas boiler is a big call. It affects what you pay on energy bills every month, how warm your house actually stays in winter, and whether your setup will still make sense five or ten years from now. Both types of boiler work well in Dublin homes, but they suit very different situations.

Here is a plain-English breakdown of how the two compare, what each one costs to run, and which is the better fit depending on where you live and what fuel you have access to.

What Is an Electric Boiler?

An electric boiler heats water using electricity instead of burning gas or oil. There is no flame, no flue, and no fuel tank sitting in your garden. For Dublin homes that are not connected to the mains gas network, or for anyone who simply wants to avoid fossil fuels, an electric boiler does the job cleanly and quietly.

Aztec Electric Boiler Range by DeWAR Plumbers

Aztec Electric Boiler Range by DeWAR Plumbers

DeWAR Plumbers install the Aztec electric boiler range. There are three models, and each one suits a slightly different type of home:

  • Aztec Classic – Tall and narrow, so it slots into a small airing cupboard without any hassle. It runs between 6kW and 12kW with 99.9% efficiency and works well in apartments, flats, and smaller houses. It is also a good match for underfloor heating.
  • Aztec Combi – The pump, expansion vessel, and automatic air vent are all packed inside the unit. You do not need extra pipework or a separate hot water cylinder. It comes with a smart digital programmer and tucks away in a utility room or cupboard behind a clean white casing.
  • Aztec System – Everything in one box – pump, auto air vent, expansion vessel, and pressure gauge. No extra plumbing on the outside. A twin channel programmer comes included for full control over your heating schedule.

Why Dublin Homeowners Like Electric Boilers?

  • No flue or fuel supply tank needed
  • 99.9% energy efficiency – almost nothing is wasted
  • Virtually maintenance free – no yearly gas safety inspections
  • Quiet – no combustion noise at all
  • Compact enough for small Dublin apartments and flats
  • Self-diagnostic checking built in
  • No risk of gas leaks or carbon monoxide

What Is a Gas Boiler?

Gas boilers are still the most common heating setup in Dublin homes. If your property is on the mains gas supply, a gas boiler heats your house and your water quickly, and the fuel costs less per unit than electricity. That is the main reason so many households stick with gas.

What Is a Gas Boiler?

Modern Condensing Gas Boilers

The old-style gas boilers wasted a lot of heat through the flue. Modern condensing gas boilers capture that waste heat and feed it back into the system, so you burn less gas for the same amount of warmth. That means noticeably lower bills compared to a non-condensing model.

RGII Registered Engineers at DeWAR Plumbers

DeWAR Plumbers is a Registered Gas Installers Company (Registration No CO572). Every job they carry out follows Irish Standards IS 813 for domestic properties.

  • All engineers carry RGII registered ID badges
  • Staff are directly employed and based locally across Dublin
  • Every engineer is qualified to work on all types of gas systems
  • DeWAR also works to IS 820 for non-domestic properties

Why Dublin Homeowners Like Gas Boilers?

  • Lower running costs – gas is cheaper per kWh than electricity in Ireland
  • Fast, powerful heating output for bigger homes
  • Parts and servicing are widely available across Dublin
  • Condensing models waste less heat than older boilers
  • Tried and tested – thousands of Dublin homes already run on gas

Gas Boiler Safety

A gas boiler is perfectly safe as long as it is installed and looked after by a qualified RGII registered engineer. You do need an annual service and a working carbon monoxide alarm. DeWAR Plumbers supply and fit a carbon monoxide detector with any gas service, because safety should never be treated as an afterthought.

What Should You Think About Before Deciding?

What Should You Think About Before Deciding?

1. Running Costs

Gas boilers cost less to run in most Dublin homes. Gas is simply cheaper per kilowatt-hour than electricity in Ireland, so your quarterly bills will usually be lower. That said, electric boilers waste almost nothing – 99.9% of what goes in comes out as heat. And if you have solar panels on your roof, you could cut your electric boiler running costs by a fair amount.

2. Installation

Electric boilers are easier and quicker to install. No flue, no gas supply line, no condensate drain. That usually means:

  • A smaller bill from the installer
  • Less mess and disruption at home
  • The job done in less time

Gas boiler installations take longer, especially if you are swapping out an old non-condensing model or putting in new pipework.

3. Safety

Electric boilers have no flame and produce no fumes. There is zero chance of a gas leak or carbon monoxide poisoning. Gas boilers need that yearly service and a carbon monoxide alarm to stay safe – miss a service, and you are taking an unnecessary risk.

4. Space and Property Size

Plenty of Dublin apartments and townhouses are short on cupboard space. The Aztec Classic and Combi electric boilers were built with exactly that problem in mind. They fit where a gas boiler never would.

For larger detached or semi-detached houses with more rooms to heat, a gas boiler usually delivers the output you need at a better price per unit of heat.

5. Environmental Goals

Ireland’s electricity grid is getting cleaner every year. The more renewable energy on the grid, the greener your electric boiler becomes. Pairing one with solar PV or a heat pump system pushes your carbon footprint down even further.

So, Which One Should You Go For?

It depends on your home, your fuel supply, and what matters most to you. Here is a simple way to look at it:

Go with an electric boiler if:

  • Your property has no mains gas supply
  • You live in a flat, apartment, or a small house
  • You do not want the hassle of annual servicing
  • You have or are planning to fit solar panels
  • You want zero risk of carbon monoxide

Go with a gas boiler if:

  • Your home has a mains gas connection
  • Keeping running costs as low as possible matters most to you
  • You have a bigger property with more rooms to heat
  • You are happy to book an annual service each year

Whichever way you go, get the job done by qualified professionals. DeWAR Plumbers cover every part of Dublin – from Dublin 1 right through to Dublin 24, plus North County Dublin and South County Dublin – and their team will tell you straight which system makes the most sense for your home.

If your current heating is sluggish, with cold spots on the radiators or poor water flow, a power flush might sort things out before you spend money on a full boiler replacement.

Conclusion

Gas boilers and electric boilers both do the job well – they just suit different homes. If you have mains gas and want the cheapest bills, gas is the obvious pick. If you do not have gas, live in a smaller property, or just want something low-maintenance and clean, an electric boiler makes a lot more sense. The most important thing, no matter which you choose, is getting it fitted properly by people who know what they are doing. DeWAR Plumbers have been looking after Dublin homes for years, and they will make sure whichever boiler you pick runs the way it should.

FAQs

Q1. Are electric boilers cheaper to run than gas boilers in Dublin?

Usually, no. Gas is cheaper per unit of energy than electricity in Ireland, so gas boilers tend to cost less to run month to month. But electric boilers run at 99.9% efficiency, meaning barely any energy goes to waste. If you have solar panels feeding into your electric boiler, your bills can come down a good deal.

Q2. Can I get an electric boiler fitted in my Dublin apartment?

Absolutely. Electric boilers are actually one of the best options for Dublin apartments and flats. They do not need a flue, gas line, or fuel tank, so they take up very little room. The Aztec Classic and Combi models installed by DeWAR Plumbers were designed with exactly these kinds of properties in mind. Ring 015143300 to arrange a free quote.

Q3. How often does a gas boiler need to be serviced in Dublin?

Once a year, every year. A gas boiler service must be done by an RGII registered engineer. It keeps the boiler safe and running properly, and most manufacturers will void the warranty if you skip it. DeWAR Plumbers carry out all gas boiler services to Irish Standards IS 813.

Q4. Do electric boilers need annual servicing like gas boilers?

No, and that is one of the biggest reasons people choose them. An electric boiler has no combustion, no flue, and no carbon monoxide risk, so there is no need for a yearly safety check. A quick look-over every few years is sensible, but the day-to-day upkeep is close to zero.

Q5. Who should I call for boiler installation or repair in Dublin?
