Truth be told, most people spend more time picking a Netflix series than they do choosing a hot water system – and then wonder why they’re cringing every time the quarterly bill arrives. Whether you’re replacing an old unit or setting up a new home, the gas vs electric hot water decision is one that affects your comfort and your costs for the next decade or more. Get it wrong and you’ll know about it.
Here are 7 mistakes worth avoiding:
1. Assuming one is always cheaper than the other
This is the big one. The electric vs gas hot water debate isn’t settled by a single number – it depends on:
- Your usage patterns
- Your energy tariff
- Whether you’re on a continuous or off-peak electricity plan.
Gas tends to have lower running costs in many areas, but that’s not a universal truth. Electricity pricing varies enormously depending on your provider and plan, so what’s cheaper for your neighbour could easily be more expensive for you.
2. Ignoring installation costs
People fixate on the unit price and forget that gas hot water vs electric hot water systems can vary significantly in what it costs to get them up and running.
If your home isn’t already connected to gas, laying that infrastructure adds real money to the equation before you’ve heated a single litre of water. Conversely, upgrading your electrical capacity for a larger electric hot water system carries its own costs. The sticker price on the unit is rarely the full story.
3. Not accounting for your household size
A system that works beautifully for a couple will leave a family of 5 shivering through cold showers by 7:30 am.
When weighing up gas vs electric hot water running costs, factor in how much hot water your household actually chews through – not what you think sounds reasonable.
These all play into whether a hot water system keeps up with your household or quietly lets you down every morning:
- Tank size
- Recovery rate
- Peak demand.
4. Forgetting about solar
If you’ve got solar panels or you’re planning to install them, an electric system could work heavily in your favour.
Gas hot water vs electric becomes a very different conversation when you’re running a heat pump off solar generation and dramatically cutting your daytime energy draw. On the Sunshine Coast, where roof space and sunshine are rarely in short supply, this is a factor that’s genuinely worth modelling before you commit.
5. Choosing a system based on what the previous owner had
Just because the last system was gas hot water doesn’t mean gas is right for you.
When evaluating an electric vs gas hot water system, start from scratch – your energy usage, your tariff, your lifestyle. And there’s even more to the equation too that can be more personal than property-specific.
What suited the previous occupant may cost you significantly more than you’d expect, particularly if your household size or daily routine looks nothing like theirs.
6. Overlooking long-term maintenance costs
The upfront price isn’t the full story. The gas hot water system vs electric comparison looks quite a bit different when you factor in:
- Servicing schedules
- Parts availability
- How the system holds up over time.
On the Sunshine Coast, salt air and humidity can accelerate wear on components, particularly in systems that aren’t rated for coastal conditions. A unit that looks like a bargain at installation can become an expensive headache within a few years if it’s not the right fit for the environment.
7. Not getting advice from an actual plumber
Online calculators and forum threads will only get you so far. In the gas hot water vs electric discussion, local knowledge makes a real difference:
- What energy plans are common in your area?
- What systems hold up best in your climate?
- Brands are worth the premium?
You know who knows the answers to all of these questions? A qualified local plumber can cut through the noise in a single conversation and point you toward the right solution for your specific situation, not just a generic recommendation.
Still not sure which way to go?
There’s no universally right answer in the gas versus electric hot water debate – but there are plenty of wrong ones, and most of them come from not asking the right questions early enough.
Here’s a few to get you started:
- What does my current energy plan actually cost per unit – and is there a better one available?
- Is my home already connected to gas, or would that need to be set up from scratch?
- How many people are in my household, and is that number likely to change in the next few years?
- Do I have solar, or is it something I’d seriously consider down the track?
- How long am I planning to stay in this property – and does that change what ‘value’ actually means here?
