The oldest energy gadget still earns its socket

A timer switch is about as unfashionable as home hardware gets, a $21 lump of plastic between the wall and the plug, and it's still one of the highest-return devices in the house if your tariff charges different prices at different times. The idea hasn't changed in fifty years: electricity is priced by when you use it on a growing number of Australian plans, and a timer moves a flexible load, the pool pump, the towel rail, the dishwasher, into the window where each kilowatt hour costs the least. No app, no cloud account, no firmware updates that brick it. We fix enough smart devices at the bench to have real respect for a switch with nothing in it that can be pushed a bad update.

The other half of the case is standby and habit loads, the things that run all day because nobody switches them off. A heated towel rail left on around the clock is the classic. The rail itself is only a couple of hundred watts, but a couple of hundred watts for 24 hours a day adds up fast, and cutting it back to two morning hours and two evening hours with a mechanical timer takes five minutes to set up and zero effort forever after. That's the honest pitch for this whole category: not a gadget that saves energy by magic, but a switch that enforces the schedule you'd run anyway if you never forgot.

Tariffs, explained without the brochure

There are three tariff shapes that matter here, and your bill tells you which one you're on. Flat rate charges the same per kilowatt hour at 3pm as at 3am, and on a flat rate a timer saves you nothing by shifting load, only by cutting total hours. Time-of-use splits the day into peak, shoulder and off-peak windows with genuinely different prices, typically with the expensive block in the evening, and this is where timers shine: the same kilowatt hour of pool filtering or water heating can cost a fraction as much at 1am as at 6pm, with the exact windows and rates varying by retailer and network, so read your own plan rather than trusting anyone's example.

The third shape is controlled load, sometimes still called off-peak hot water, where a hardwired circuit, nearly always the electric storage water heater, is metered separately at a lower rate and the network switches it on during slack periods. If your hot water is already on controlled load, the timing is being done for you upstream and there's nothing for a timer to improve. If it's not, that's a conversation with your electrician and retailer, not a plug-in gadget, and I'll come back to why. The broader load-shifting picture, including where smart plugs and energy monitors fit, is covered in our smart home power savings guide, and a timer is the simplest possible tool in that kit.

The hot water question, answered honestly

This guide has hot water in the title, so here's the part most listings skate past: you can't put a typical Australian electric hot water system on a plug-in timer, because it isn't plugged in. Storage water heaters run on a dedicated hardwired circuit, usually straight off the switchboard, and anything that interrupts fixed wiring is licensed electrician territory in Australia, full stop. That's not me covering myself, it's the law, and it's also just correct: a water heater is a sustained high-current load, and switching it wants properly rated gear installed by someone who can test their work.

What you can do about hot water is worth doing though. If you're on a time-of-use plan with low overnight rates, a sparky can fit a hardwired timer or a contactor arrangement so the element only heats in the low-price window, and a unit like the Bewinner below is exactly the class of hardware they'd wire in for a pool pump or similar fixed load. Alternatively, moving the water heater to a controlled load tariff gets the network to do the switching. Either way the plug-in timers in this guide are for the rest of the house: pumps, rails, chargers, lamps, dehumidifiers, the fish tank, anything that ends in a plug.

What must never go on a timer

The short list first: fridges and freezers, anything medical, the NBN box and router if anyone relies on the connection, security cameras and recorders, and sump or greywater pumps that need to run when water arrives rather than when the clock says so. A fridge cycled off for hours to chase a tariff saves cents and risks a bin full of food, which is the worst trade in home energy. Medical gear needs no explanation beyond: never. And a modem on a timer takes out phones, alarms and cameras with it, which people mostly discover the bad way.

Heaters deserve their own paragraph. A timer that turns a heater off after an hour is a reasonable safety net. A timer that turns a heater on while nobody's in the room is how house fires start, and no schedule is worth an unattended radiant bar heater. If a heater does go on a timer, it should be a modern unit with its own thermostat and tip-over protection, in a clear space, and only ever switching off, not on. While we're on electrical safety: a standard Australian socket is good for 10 amps, about 2,400 watts, and every timer here inherits that ceiling or less. Never stack a heater onto a powerboard, timer or not, and if a plug or timer body ever feels warm to the touch, that circuit is telling you something and it's worth acting on.

The maths, with the assumption stated

Take the AU average tariff at roughly 33c per kilowatt hour and the arithmetic gets simple: a 2,000W appliance flat out costs about 66c an hour, a 200W towel rail about 6.6c an hour, and a 10W phone charger about 0.3c an hour. Those three numbers explain most timer decisions. Timing the charger is pointless, the number's already nothing. Timing the towel rail from 24 hours down to 4 saves you twenty hours of 6.6c every day, which is real money over a year. And a 1,000W pool pump running its filter cycle in a low-rate overnight window instead of the evening peak saves the gap between the two rates on every one of those kilowatt hours, every day, forever.

The discipline is measuring before guessing, because wattage labels state maximums and real appliances draw what they draw. A plug-in energy meter, or one of the metering models from our smart plugs guide, tells you in a day whether a load is worth shifting. As a rule of thumb, anything under about 50 watts isn't worth a timer's socket space for savings alone, resistive heating loads and pumps almost always are, and the awkward middle is electronics with standby modes, where cutting power entirely can cost you settings or recordings. Measure, then decide, then set the schedule once and forget it, because a timer's whole advantage over willpower is that it doesn't have moods.

Mechanical or digital, pins or programs

Mechanical pin timers like the HPM and Jackson twin packs are a clock motor driving a dial, with the day divided into segments you push down to switch the load on. The Jackson gives you 48 switching cycles a day at 15 minute resolution, which sounds coarse until you realise almost every real schedule is round numbers anyway. Their strengths are the price, the glanceability, you can see the whole day's schedule on the dial from across the room, and the fact that there's no memory to lose and no menu to misprogram. Their weaknesses: the same schedule runs every day of the week, they tick audibly in a quiet room, and a blackout stops the clock, so the schedule runs late until you spin the dial back to the right time.

Digital timers like the Sansai fix all three weaknesses at once. Twenty on-off programs a day at one minute resolution, a seven day cycle so weekends can differ from weekdays, summer and winter time options, and a backup battery that holds the clock and programs through a blackout, which is the single most underrated spec in this category. The cost is a menu, and menus on $23 hardware are never a joy: small buttons, terse LCD abbreviations, and a real chance of leaving it in the wrong mode if you rush. My honest guidance is that households set a digital timer once a season and forget it, so the clunky programming matters less than the battery and the weekday flexibility, but if the person setting it hates fiddly menus, the pin dial wins on being impossible to get wrong.

Contacts, ratings and why timers die

A timer is a relay or a set of cam-driven contacts switching real current, and contacts are consumables. Every switch-on across an inductive load, a pump motor, a compressor, draws an arc that erodes a little metal, and a timer rated to its limit switching a motor twice a day lives a much shorter life than the same timer running a lamp. The Sansai states its ceiling plainly, 2,400W at 240V, 10A maximum, and the honest way to read any such rating is as a resistive figure: for motors and pumps, staying well under it is what buys you years. When a timer starts sticking on, buzzing at the changeover or switching intermittently, the contacts are pitted and the unit is finished. They're not repairable at these prices, and the ones that come through our Erina workshop get a post-mortem and a recommendation, not a resurrection.

The HPM twins bring up a spec worth explaining: double pole switching, which breaks both active and neutral rather than active alone. For a device that's switching something outdoors, damp-adjacent or heating-related, full isolation of both conductors when off is simply better practice, and it's the sort of detail that shows up on gear designed for AU wiring rules, the HPM listing states Australian origin, rather than a generic global product with an adapter plug moulded on. It's also the reason I'd put the HPM on the loads that matter most rather than on whichever socket matters least.

The security side benefit

Timers earn a second job when the house is empty. A couple of lamps switching on random-ish schedules reads as occupancy from the street far better than a porch light burning at noon does, and the AIMALL below has an explicit random mode built for exactly this, wobbling its programmed times so the pattern doesn't repeat like a metronome every night. A mechanical timer does a cruder version of the same trick, and two of them from a twin pack running a lamp in different rooms costs almost nothing. It pairs naturally with the motion lighting from our solar security lights guide: scheduled interior light says someone's home, motion-triggered exterior light says you've been noticed, and neither needs a subscription.

Keep the security schedule plausible. Lights that snap on at exactly 18:00:00 and off at exactly 22:00:00 every day of a two week holiday are their own tell, which is what the random offset solves. And if you're going away in summer, the same timer bank that runs the lamps can run the fish tank, the irrigation controller's pump and the dehumidifier in the boat shed, which is the point where a $21 twin pack has quietly become infrastructure. Label each timer with what it runs and when you set it. Future you, standing at the switchboard in July trying to remember why the hallway lamp comes on at dawn, will be grateful.

Side-by-side comparison

What we see fail at the bench: appliance timers

Timers are simple enough that their failures are textbook, and we see the same three at the bench whether the patient is a $21 pin timer or the timer section inside a much dearer appliance. All three are worth knowing before you buy, because two of them are avoidable with nothing more than sensible loading, and the third is a battery.

Decision tree: which one should you actually buy?

• Same schedule every day and you want it name-brand? → The HPM twin pack at $34. Double pole isolation, Australian origin on the listing, and two timers means the second one finds a job within the month.
• Testing the habit, or filling several sockets on simple schedules? → The Jackson twin pack at $21. About $10.50 a timer with override and indicator, and the worst case is a spare in the drawer.
• Weekends different from weekdays, or minute-level timing? → The Sansai at $23. Seven day cycle, 20 programs a day, a stated 2400W ceiling and battery-backed memory that survives blackouts.
• Pool pump, or a hardwired load like hot water? → The Bewinner at $31, bought to hand to your electrician, whose install is part of the budget. For hot water, ask them about controlled load tariffs at the same visit.
• Lights that look lived-in while you're away? → The AIMALL at $30. The random mode wobbles the schedule so the pattern doesn't repeat, which is the detail that sells it from the street.
• An appliance that trips the safety switch, runs hot or died on a timer? → Stop using it and bring it in to our Erina workshop. We'll tell you whether the fault is the appliance, the timer or the socket before you replace anything.

Frequently asked questions

Can I put my hot water system on a plug-in timer?

No, and it's worth understanding why. Australian electric storage water heaters are hardwired on a dedicated circuit rather than plugged into a socket, so there's physically nothing for a plug-in timer to attach to, and interrupting fixed wiring is licensed electrician work by law. What you can do is have an electrician fit a hardwired timer or contactor so the element heats only during your low-rate tariff window, or move the heater onto a controlled load tariff where the network does the off-peak switching for you. Both are one visit's work, and if you're already getting a sparky in, having them quote both options at once is the efficient move.

Do appliance timers actually save money?

Only in two situations, and it's worth being clear-eyed about both. On a time-of-use tariff, a timer saves the price gap between peak and off-peak on every kilowatt hour it shifts, which adds up fast on daily loads like pool pumps. On any tariff, a timer saves money by cutting total running hours, like a towel rail dropping from 24 hours a day to 4. What a timer can't do is make a small load worth timing: at roughly 33c per kilowatt hour, a 10W charger costs under a cent an hour, and no schedule rescues that. Measure the load first, then decide.

What should never be put on a timer?

Fridges and freezers, because hours off risks a bin of spoiled food to save cents. Anything medical, without exception. The modem and router, because phones, alarms and cameras ride on the connection. Security cameras and recorders. And pumps that respond to events rather than schedules, like sump pumps. Heaters are the special case: a timer switching a heater off is a reasonable safety net, but a timer switching a heater on in an empty room is a fire risk no saving justifies. If a heater must be scheduled at all, it should be a thermostat-equipped unit with tip-over protection, switching off only, and never on a powerboard.

Are mechanical or digital timers better?

Different jobs. A mechanical pin timer is better when the schedule repeats every day and the person setting it wants zero chance of misprogramming: the whole day is visible on the dial, and there's no menu and no memory to lose. Digital wins the moment weekdays and weekends differ, timing needs to be tighter than 15 minutes, or blackouts are common, because a battery-backed digital timer holds its clock and programs through an outage while a mechanical dial simply runs late until corrected. Households that hate fiddly menus should weight that honestly, since a digital timer programmed wrong is worse than a mechanical one programmed right.

How much load can a plug-in timer switch?

The ceiling for anything plugged into a standard Australian socket is 10 amps, about 2,400 watts at 240 volts, and the Sansai in this guide states exactly that as its maximum. Two cautions sit under the number. First, ratings are quoted for resistive loads, and motors, pumps and compressors draw a surge at switch-on that erodes contacts, so keep inductive loads well under the printed figure if you want years from the unit. Second, some timers on this list don't print a rating in the listing text at all, in which case the number stamped on the unit body is the one that governs, and lamps-only is the safe assumption until you've read it.

Should I buy a timer or a smart plug?

A smart plug does everything a digital timer does plus remote control, energy metering on the good ones, and schedule changes from your phone, so if you're already running a smart home platform, it's usually the better buy. A dumb timer wins on three fronts: it costs less, it keeps working through wifi changes, router swaps and app shutdowns, and there's nothing cloud-side to be discontinued. For fixed schedules that never change, the fish tank, the towel rail, the pool pump, I'd genuinely rather own the $10 mechanical unit. For loads you want to measure or adjust remotely, our smart plugs guide covers the metering models worth having.
