Electric Combi Boilers: Pros, Cons & Are They Right for You?

Published on 19 May 2025 at 08:24

The Pros of Electric Combi Boilers

1. Compact & Space-Saving Design

Electric combi boilers are small and wall-mounted, with no need for extra tanks. This makes them perfect for London flats where space is at a premium.

2. No Mains Gas Required

Ideal for modern apartments in W2, where mains gas may be unavailable or being phased out.

3. Low Installation Costs

Without flue requirements or gas-safe regulations, installation is simpler and often cheaper than gas systems.

4. Quiet Operation

No noisy burners — electric boilers are much quieter than their gas counterparts.

5. Energy Efficient

Electricity is 100% efficient at the point of use, meaning all the energy is used to heat your water or radiators.

6. Safe & Low Maintenance

No risk of gas leaks, no carbon monoxide, and fewer moving parts means less maintenance.

❌ The Cons of Electric Combi Boilers

1. Higher Running Costs

Electricity is typically more expensive per kWh than gas, so your energy bills may be higher depending on usage.

2. Not Ideal for High-Demand Homes

They struggle to supply hot water to multiple outlets simultaneously — better suited for 1-bathroom flats.

3. Power Cuts = No Hot Water

Since they run entirely on electricity, any power outages will shut down your boiler. ( A Gas boileralso needs electricity to work)

4. May Need Electrical Upgrades

You might require a fuse board upgrade or additional circuits to meet the demands of the boiler.
