How Much Does It Cost to Run an Electric Boiler?
Formula: Running Cost (€) = Boiler Power (kW) x Hours Used x Electricity Price (€/kWh)
Example: A 9kW boiler used 4 hours daily at €0.40/kWh costs €14.40 per day.
Cost reduction strategies:
- Install Day/Night meter for storage boilers (utilise cheaper night rates)
- Improve home insulation for shorter operating times
Are Electric Boilers More Expensive Than Gas or Oil?
Heating your home using an electric boiler is always going to be more expensive due to higher electricity costs versus gas/oil.
| Boiler | Price | Cost per Day | Phased Out? |
|---|---|---|---|
| Electric | €600 - €1,200 | €12 to €20 | No |
| Gas | €1,500 - €3,500 | €10 to €16 | Yes |

How Does an Electric Boiler Work?
An electric boiler provides hot water and central heating. Instead of using gas or oil to produce heat, an electric boiler uses electricity. It works just like an electric kettle, except it's sized to heat your home.
Heating elements warm water, which circulates to radiators, underfloor heating, or hot water cylinders. Boilers are smaller, more compact, requiring no flue, fuel pipes, or outdoor tanks.
What Electric Boiler Types Are There?
- Electric Combi Boiler (Direct) — Heats water on demand without requiring a tank
- Storage Boiler — Stores heated water for use; compatible with day/night meters
- Dry Core Storage Boiler — Heats bricks overnight, releases heat into water daily
- Combined Primary Storage Unit (CPSU) — Large unit suited for commercial applications

Electric Boiler vs. Heat Pump
| Attribute | Electric Boiler | Heat Pump |
|---|---|---|
| Operating Principle | Converts 100% electricity to heat | Transfers heat from air/ground |
| Energy Efficiency | High (up to 100%) | Very High (COP 3.0-4.5) |
| Initial Cost | Low (€600-€2,500) | High (€8,000-€15,000+) |
| Running Cost | High | Low |
| Installation | Simple, compact | Complex, requires outdoor unit |
| Grants | No | SEAI grants available |
Choose Electric Boiler: Small, well-insulated homes with limited budgets.
Choose Heat Pump: Large homes, willing to invest upfront for minimal running costs.
How Efficient Are Electric Boilers?
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. Gas boilers max at 93% efficiency by comparison.
