A new electric boiler can cost between €600 to €2,500 with more expensive models often costing more. Electric boilers are more expensive to run compared to gas or oil boilers, as the price of electricity is usually much higher than that of gas. Unlike gas or oil boilers, electric boilers are not being phased out as they don't directly run on a carbon emitting fuel.
The price of a new electric boiler is typically between €600 to €2,500 depending on the size and model. While smaller boilers tend to be cheaper, they may not be as efficient as larger models.
A premium electric boiler will typically be more expensive, reaching up to €3,000. However, it will also tend to be longer-lasting.
Installation prices for an electric boiler typically range from €500 to €1,500.
The process is often completed within one to two days, making it much faster and less disruptive than installing a gas or oil boiler, which require running new fuel lines and installing flues.
An electric boiler is an excellent choice for certain properties and circumstances:
Before installation, an electrician will need to check your home's main fuse and wiring, especially in older homes. Electric boilers require a significant power draw.
Given that individual expectations and budget for a new electric boiler vary, it's difficult to give a definitive recommendation as to which is the best boiler available on the market.
What we can advise is the factors to take into consideration before buying a new boiler. By having an idea of this, you will be better placed to compare what is available on the market.
Factors to consider include:
Below you will find an overview table of some popular electric boiler brands and their estimated price range:
| Brand | Estimated Price Range (EUR) |
|---|---|
| Elnur Gabarron | €1,000 - €2,500 |
| Haetrae Sadia | €800 - €1,800 |
| Thermaflow | €700 - €1,500 |
| Viessman | €1,500 - €3,000 |
| Stiebel Eltron | €1,000 - €2,500 |
The simple way to estimate your cost is to use the following formula:
Running Cost (€) = Boiler Power (kW) x Hours Used x Electricity Price (€/kWh)
| Variable | Description | Typical Value |
|---|---|---|
| Boiler Power | The maximum kilowatt rating of your electric boiler. | 6 kW to 12 kW |
| Hours Used | The total hours the boiler is actively heating water. | Varies greatly (e.g., 2–6 hours/day) |
| Electricity Price | The unit rate you pay your supplier for electricity. | Varies by supplier and plan |
Let's assume a mid-sized, efficient home uses a 9 kW electric boiler for an average of 4 hours a day, and the standard electricity rate is €0.40 per kWh:
9 kW x 4 hours x €0.40 kWh = €14.40 per day
Given that the average cost of electricity is higher than that of gas or oil, heating your home using an electric boiler is always going to be more expensive.
Having said that, there are several factors that impact on the total cost of heating a home regardless of which type of boiler you have, including:
The following table gives a basic breakdown of the difference in price between several types of boilers:
| Boiler | Price | Cost per day | Phased Out? |
|---|---|---|---|
| Electric | €600 - €1200 | €12 to €20 | ❌ |
| Gas | €1500 - €3500 | €10 to €16 | ✅ |
| Oil | €3000 - €3500 | €13 to €22 | ✅ |
The advantages of electric boilers lie more in their energy efficiency and minimal maintenance, no bleeding for example, and not in their low running costs.
Even though they are more energy efficient, the amount of energy saved is not enough to offset the higher cost of electricity, and it is worth switching energy providers to reduce the costs of electrical boilers.

Can An Electric Boiler Produce Carbon Monoxide?
As electric boilers, and their condensing boiler alternatives, don't burn a fossil fuel to produce heat, there is no risk of carbon monoxide poisoning.
Just like any other type of boiler, an electric boiler provides hot water and central heating. Instead of using gas or oil to produce heat, however, an electric boiler uses electricity. It works just like an electric kettle, except it’s sized to heat your home.
The electricity heats a series of elements inside the boiler, which then heats the water. Once the water has been heated, it is then pumped around your home to where it’s needed. It can be used to heat the following:
While electric radiators come in a variety of sizes, they tend to be smaller and more compact than gas, biomass or oil boilers. They also do not require any of the following:
Since they don’t need a flue (the pipe that runs from the boilers to outside your house) and are smaller than other boiler types, electric boilers can be fitted almost anywhere and require less installation time.
Are There Boiler Grants in Ireland? Unfortunately, there are no longer boiler grants available in Ireland. The government is also planning on phasing out gas and oil boilers by 2025. However, there are grants available from the SEAI for heat pumps and solar water heaters.
We break down the main types of electric boilers below.
Selectra's Electric Boiler Tip
"Make sure that the technician who carries out any work on your electric boiler is an RECI registered electrician to ensure that the work is carried out to a high standard of both safety and service."
Electric and gas boilers are similar in many ways, from their function to the different types on the market.
For houses that don’t require any additional upgrades to the electrical infrastructure, the installation costs are also much the same for electric and gas boilers. Electrical boilers tend not to need replacing like gas boilers.
Before choosing to switch, or which to opt for in a new build, it is important to know the advantages of both.
As gas and oil boilers are phased out, many homeowners are comparing the low-carbon alternatives: electric boilers and electric heat pumps.
While both run on electricity, they operate on fundamentally different principles.
| Attribute | Electric Boiler | Heat Pump (Air or Ground Source) |
|---|---|---|
| Operating Principle | Converts 100% of electricity into heat. | Transfers heat from the air or ground into the home. |
| Energy Efficiency | High (Up to 100% conversion efficiency). | Very High (COP of $3.0 - 4.5$ – for every 1 unit of electricity, it produces 3 to 4.5 units of heat). |
| Initial Cost | Low (€600 - €2,500 unit cost). | High (€8,000 - €15,000+ installed). |
| Running Cost | High (Expensive electricity is the primary fuel source). | Low (Extremely efficient use of electricity). |
| Installation | Simple and compact; ideal for small spaces. | Complex and bulky; requires space for an outdoor unit and indoor cylinder. |
| Grants | No government grants available. | SEAI Grants are available for unit and installation costs. |
Electric boilers typically have an efficiency rating of 99 to 100%. This means that for every euro you spend on heating, very little (if any) is wasted on lost energy.
This is also great when it comes to having your boiler serviced since it guarantees efficient functioning for longer.
In comparison, gas boilers typically have a maximum efficiency rating of 93%. For every euro spent on heating, around seven cents are wasted, not including the additional cost for a gas boiler service.
Both electric and gas boilers are ideal for different households, and there are different factors which will determine which one is ‘better’. Gas boilers are generally more powerful and can meet higher heating and hot water demands, and they are cheaper to run.
| Attributes | Electric | Gas | Oil | Biomass |
|---|---|---|---|---|
| Initial Cost | Low | Moderate | High | High |
| Installation Cost | Low | Moderate | High | High |
| Running Cost | High | Moderate | High | Low |
| Efficiency | High (95-99%) | Moderate (70-90%) | Moderate (70-90%) | High (80-90%) |
| Environmental Impact | Low (no direct emissions) | Moderate (greenhouse gas emissions) | High (greenhouse gas emissions) | Low |
| Maintenance | Low | Moderate | Moderate | Moderate |
| Fuel Source | Electricity | Natural gas | Oil | Biomass (wood pellets, chips, etc.) |
