Gas vs Electric Instant Hot Water Systems - Which one is right for you?

When it comes to instantaneous hot water systems, there are two main types: gas and electric. Both have their own advantages and disadvantages, so it can be tricky to decide which one is right for you. We will take a look at both types of instant hot water systems and help you decide which one is best for your home.

Gas Continuous Flow Hot Water Systems

Gas instant hot water systems are powered by natural gas. They are more expensive to install than electric systems, but they are cheaper to run in the long term. Gas systems also have a higher flow rate, so they can provide hot water for multiple taps at the same time. The main downside of gas systems is that they require ventilation and can produce carbon monoxide, so they need to be installed by a qualified professional.

Pros and cons of a gas instantaneous hot water system

Pros

• Generally cheaper to run than electric systems
• Have a higher flow rate so can handle more than one tap at a time

Cons

• More expensive to buy than electric
• More expensive to install as need to run pipes for both water and gas
• Has to be installed in an open area or well-ventilated space (flued)

Electric Tankless Hot Water System

Electric instant hot water systems are powered by electricity. They are cheaper to install than gas systems, but they are more expensive to run in the long term. Electric systems also have a lower flow rate, so they might not be suitable for homes with multiple bathrooms. The main upside of electric systems is that they are much easier to install than gas systems and don't require ventilation.

Pros and cons of electric instant hot water systems

Pros

• Less expensive to purchase than a gas system
• Easier and less expensive to install than gas (as long as the electrical system is suitable)
• Can be installed in enclosed areas

Cons

• Generally more expensive to run than gas
• Have a low flow rate, so can't handle multiple taps at once

So which instant hot water system is right for you?

To decide this you need to ask yourself the following questions:

1. How much hot water do I need at any given time?
2. Do I have natural gas already or do I need to get it fitted?
3. Do I have a well-ventilated area to place the hot water system?
4. Is my switchboard up to date with a suitable circuit?

Once you've asked these questions you will most likely be pointing towards either gas or electric. If not, then it comes down to upfront vs ongoing price.

We trust this has helped you make the right decision with your instantaneous hot water system.
