What Is an Electric Combi Boiler?

An electric combi boiler (short for "combination boiler") is a compact, all-in-one unit that provides both central heating and domestic hot water, without the need for a separate water tank or gas supply.

Instead of burning gas or oil, it uses electricity to heat water on demand — meaning it doesn’t store hot water but heats it instantly as needed.

‍

Key Features:

• All-in-one heating + hot water system
• Powered entirely by electricity
• No flue, gas connection, or fuel storage required
• Compact, wall-mounted design

‍

‍

‍

Who Is It Best For?

Electric combi boilers aren’t for every home — but in the right situation, they’re a fantastic, low-maintenance option.

✅ Ideal for:

• Smaller homes, condos, or apartments with lower heating demands
• Homes without access to gas lines
• Renovations or off-grid properties
• Homeowners looking to lower carbon emissions

❌ Not ideal for:

• Large homes with high hot water usage
• Properties with multiple bathrooms used simultaneously
• Areas with high electricity rates and no time-of-use billing options

Pros of Electric Combi Boilers

Let’s take a look at the reasons homeowners in BC are considering the switch:

‍

1. Zero Carbon Emissions (at the point of use)

Electric boilers don’t burn fossil fuels, which means no flue gases and no carbon monoxide risk. Combine this with BC's clean hydroelectric grid, and you’ve got a nearly carbon-neutral home heating system.

‍

2. Compact and Quiet

These systems are often the size of a small suitcase and operate almost silently — perfect for smaller spaces or wall installations inside a utility closet.

‍

3. Lower Upfront Costs

Compared to high-efficiency gas systems, electric combi boilers tend to be more affordable to install (no gas hookup, flue work, or ventilation needed).

‍

4. Low Maintenance

With no combustion process, fewer moving parts, and no risk of gas leaks, electric boilers require minimal maintenance.

‍

‍

‍

Considerations Before You Commit

‍

🔌 Power Demand

Electric combi boilers typically need a dedicated 240V circuit and can draw significant power, especially when heating water for both space heating and domestic use. This might require an electrical panel upgrade, especially in older homes.

‍

💧 Flow Rates

Because they heat water instantly, electric boilers may struggle with high simultaneous water usage (e.g., running two showers and the dishwasher at once).

‍

💡 Operating Costs

In regions where electricity is expensive, operating an electric boiler can be pricier than natural gas — but in BC, where hydro is relatively affordable and time-of-use billing exists, it can still be a competitive choice.

So… Is It Right for You?

An electric combi boiler can be an excellent choice for:

• Homeowners looking for a compact, simple system
• Homes without gas access or where gas upgrades are costly
• Environmentally-conscious households wanting to reduce emissions
• Small to mid-sized BC homes with modest hot water needs
