TLDR: How induction cooktops can make the new generation of electric cookers more cost-effective so that they challenge the use of gas.
When induction cooktops started to become well known a decade or so ago the whole idea of cooking technology seemed to have become more sophisticated. While there had always been competition between gas and electricity, it was largely concerned with the speed at which cooking could start and the responsiveness when the user turned the heat down, while the cost of operation is always a tricky issue.
But at least the two options were easy enough to understand. Induction hobs, though, were something of a mystery. How economical they were to run was a secondary consideration; what everyone wanted to know first was how to use them.
In fact, an induction cooktop can be economical to use, and although there is no straightforward factual comparison to make life simple in this respect, there are guidelines that can make you a more cost-effective cook.
Induction is Science, not Magic
Let’s look at how induction works. A magnetic field is generated within the hob which creates an electrical current in iron or steel – and only iron or steel (magnetism doesn’t work with other materials). So, the pan must be cast iron or stainless steel, or at least the base does. What is getting hot is the pan itself, not a heat source underneath it. Take the pan off the hob and the magnetic field has nothing to affect, so it stops having any impact.
Thermal Efficiency: Where the Energy Actually Goes
The argument in favour of induction cooktops rests on the fact that the system only heats up the pan that is sitting on it. No iron or steel means no action and therefore no expense. While a gas hob will heat up whatever pan is above it, it also spreads the joy to the surrounding area, so there is waste – and we all know that waste is a bad thing in these eco-conscious times.
Sydney Energy Tariffs & Daily Supply Charges
It is not simply a straight choice between gas and electricity, although that obviously comes into it. But there is also competition between suppliers. So, as with other things that consume energy, such as heating and air conditioning, we are already in the realms of speculation, bargain-hunting and personal choice – and it’s worth understanding off-peak electricity times for NSW homes, since running an induction cooktop during cheaper hours can add up over time. What electricity has going for it in the kitchen is mainly convenience, and in the 21st century that isn’t as important. Suffice it to say that an induction cooktop is more efficient and uses less electricity than a conventional electric hob. If you want to weigh this up against your overall household spend, our complete guide to electrical costs in Sydney is a useful reference point.
The Gamechanger: Rooftop Solar Integration
From this point we move to a wider perspective: not just how much energy we need but how we get it. Rooftop solar integration means having solar panels on the roof that make a contribution to our energy requirements, even if they don’t cover the whole amount. It is a step along the road to self-sufficiency, which can be a good feeling – and it’s one of several smart home electrical upgrades that add value to Sydney properties.
Summary Verdict & Savings Breakdown
The specific figures for your property are unique, so the best you can do here is look at the individual factors that can reduce your energy bills. Yes, induction cooktops are more targeted and less wasteful, but you’re going to need suitable pots and pans. And yes, having some solar power helping you out can save money – once you get past the cost of having them installed. It’s a similar equation to the one we walk through in our piece on how much money you’ll actually save with LED lighting – small efficiency gains that add up over time.
It is, therefore, very much a case of analysing your needs and what you are prepared to do to satisfy those needs.
Upgrading to an induction cooktop is indeed an “upgrade” in terms of sophistication, but to make it work for you economically you will have to look at the bigger picture. Go induction, go solar, shop around for a cheaper energy supplier or just think twice before doing any cooking? It’s your choice.
