Choosing a new hot water system for your home can be overwhelming — especially when you’re deciding between gas and electric options. Each has its pros and cons, and the right choice depends on your household’s needs, budget, and setup.
In this article, we’ll break down the key differences to help you make the best decision for comfort, energy savings, and long-term performance.
What’s the Main Difference?
- Gas hot water systems use natural gas or LPG to heat water.
- Electric hot water systems use electricity to power a heating element inside the tank or instant unit.
Both can deliver hot water reliably, but they differ in costs, speed, energy efficiency, and installation.
Pros & Cons of Gas Hot Water Systems
✔ Pros:
- Lower running costs (especially if you already use gas in your home)
- Heats water faster than electric systems
- Works even during power outages (for tank models)
- Good option for larger households
✖ Cons:
- Requires a gas connection or LPG bottle
- Higher upfront installation cost
- Outdoor installation often required (for ventilation)
Pros & Cons of Electric Hot Water Systems
✔ Pros:
- Lower upfront cost and easier to install
- Available in both tank and instant models
- More flexible placement (indoor or outdoor)
- Good for smaller homes or light usage
✖ Cons:
- Higher energy bills, especially if not on off-peak tariffs
- Slower heating time compared to gas
- Doesn’t work during blackouts (unless you have solar backup)
Which One Is Better for You?
Here are a few quick tips:
| Your Situation | Recommended Option |
|---|---|
| You already have a gas connection | Go for gas |
| You live in an apartment or small home | Electric might be more practical |
| You want lower energy bills long term | Gas (or consider solar) |
| You want the lowest upfront cost | Electric |
| You have solar panels | Pair with electric system for savings |

What About Instant or Continuous Flow Units?
Both gas and electric systems come in instantaneous (tankless) models, which only heat water when you need it. These are more compact and energy-efficient, but they might have lower flow rates if multiple taps are running.
