A question we get often on the showroom floor is "Is that going to rack up my power bill?"
Fair question! Nobody wants to install a heated towel rail only to discover it's expensive to run. The good news is that most of the common concerns - running costs, leaving them on overnight, vertical rails and bar spacing, are all based on myths rather than facts. Once you know how heated towel rails actually work, these worries are easy to put to rest.
At Elite Bathroomware, our team helps homeowners, designers and builders choose heated towel rails every day. We stock a wide range of leading brands that have heated towel rails in their product range, including Code Interiors, Heirloom, Atlantis and Newtech. That means our advice isn't based on selling one product, it's based on helping customers choose the right solution for their bathroom.
Running Cost & The Goldair Timer
The Goldair power-saving timer is the single easiest way to bring the number down, and it's why it's included as a standard addition, rather than treating it as an optional extra. Instead of having your rail running continuously, the timer automates the whole cycle. Heat when you need it, off when you don't!
No remembering to flick a switch before bed or manually managing the drying window. You set it once around your schedule and it does the rest. The savings aren't a trick or a gimmick. It's simply the rail drawing power for a scheduled window instead of all day, every day.
Every Code Interiors heated rail includes a Goldair power-saving timer as a standard. Manufactured by one of New Zealand's most recognised home heating brands, Goldair's timer is simple to use, reliable and designed to help you get the most from your heated towel rail without the guesswork.
Another brand we stock at Elite, Heirloom, has select heated towel rails that include ESP (Energy Saver Pulse) technology. ESP is a smart electronic controller built into select heated towel rails to cut power by up to 50% while keeping towels warm and dry. Instead of using a basin on-off timer, it toggles between two main power levels using a simple touch pad. The Heirloom Genesis 825 Ladder in Chrome & the Heirloom Genesis 1025 in Chrome are available in the Power Saving Timer alternative.
Here's what it looks like in actual dollars:
Published NZ figures for running a heated towel rail vary widely, from roughly $44 a year on a 4 hour timer and up to $260-$310 if left on continuously. The gap is real, and it comes down to two things, the wattage of the element and how many hours a day it's drawing power.
The spread is exactly why usage time often has a bigger impact on running costs than small differences in wattage. A rail left running continuously sits at the top of the range regardless of how efficient the element is. The same rail on a scheduled timer, running around your towel usage, sits close to the bottom of the range.
Can You Leave It On Overnight?
The short answer: yes.
This is one of the most common things people assume is wasteful or risky and neither are true at a normal household use. A heated towel rail isn't a heater in the room-warming sense, it's a low-wattage element built to run for long stretches without an issue. Leaving it on overnight to make sure towels are properly dry by the morning is what they are designed for.
If you want to keep an eye on cost, the Goldair timer handles that for you. But running it overnight occasionally or as a habit isn't going to damage the unit or blow out your power bill in the way people assume it will.
Vertical Rails: The Misconception
Vertical rails get a bad rap. The usual complaints we hear are "they don't hold enough towels" or "they look flimsy next to a horizontal ladder". Neither of these complaints are really about the vertical rail itself, they're more about the bathroom.
Vertical rails are better for narrow spaces, tight ensuites or walls where a horizontal ladder simply won't fit. Because the bars run vertically, rather than horizontally, you get more hanging points for the wall space they occupy. For smaller Auckland bathrooms especially, vertical rails often hold more usable towel space than a horizontal one, crammed onto the same wall.
The underrated reputation isn't a myth to bust - vertical rails were never competing with horizontal ones as they solve a different problem.
At Elite we have a few brands that offer vertical heated towel rails, such as; Code Interiors offer both a Nature Style or Lineare Style.
Heirloom offers vertical rails in Heiko, Aura and Studio Styles.
Atlantis offers vertical rails in Icona Chateau and Icona Mont Styles.
Newtech offer vertical rails in Titan, and Polo Styles
Why the Bar Spacing Looks Odd (But Actually Makes Sense)
Customers sometimes look at our ladders and ask why the gaps between the bars aren't even. It looks, at a glance, like an inconsistency.
But it's deliberate! The uneven spacing is built for how towels are actually used, not for symmetry on a spec sheet. Wider gaps lower down allow for larger sized bath towels, or towels folded multiple times, so they hang properly and get full airflow, instead of bunching. Tighter gaps up the top suit hand towels or folded towels that need a second bar for draping. You may think evenly spaced bars look nicer, but it's the uneven bars that actually work when you hang your full towel.
Why Some Rails Run Patchy
The single most common complaint across the whole category isn't a safety issue; it's rails that run hot at the top/bottom and lukewarm in the middle. It's a cheaper unit problem and it's the kind of thing you don't notice until you've owned one for a few months.
It comes down to the build and quality of the product. A rail with an undersized or poorly placed element can't carry consistent heat the full length of the ladder, so the bars furthest away from the element run cooler. That's a component problem and happens when rails are built down to price rather than standard.
One advantage we've seen with premium heated towel rails is more consistent heat distribution. Brands such as Code Interiors are designed with correctly sized and positioned heating elements to deliver more even warmth across the rail, rather than concentrating the heat around the connection point. It's one of the differences we encourage customers to look for when comparing options in the showroom.
What Separates a Good Heated Towel Rail from a Cheap One?
Not all heated towel rails are built the same. While most look similar at first glance, differences in heating, elements, materials, finishes and the overall construction can have a noticeable impact on performance and longevity.
At Elite Bathroomware, we stock a carefully selected range of heated towel rail brands to suit different budgets and styles. If you're looking for a premium option, Code Interiors is our standout recommendation. Designed with consistent heat distribution, durable construction and high-quality PVD finishes, Code Interiors heated towel rails combine everyday performance with contemporary design.
Alongside Code Interiors, we also stock trusted brands including Heirloom, Atlantis, Newtech and more, each offering their own strengths in design, finish options, and price point. Our role is to help you compare the differences and choose the heated towel rail the best suits your bathroom.
The Auckland Humidity Problem
East Tamaki and the greater Auckland region run humid. That’s the real reason these sell, not the warm-towel feeling.
Damp bathrooms don’t dry towels properly on their own, especially through winter. A folded, damp towel left on a hook is exactly the environment that mould and mildew need. A heated rail (timer or not) keeps towels properly dry between uses.
Finding the Right Type for Your Bathroom
At Elite Bathroomware, we have a large range of ladders, vertical rails, horizontal bars, and floor standing rails. Each one is built to solve a different bathroom problem.
Ladders are the all-rounder. Wide bar spacing at the bottom, tighter up top, built to hold a full range of towels at once. If you’ve got the wall space and want maximum hanging capacity, this is the default pick. Shop all heated towel rails & ladders here.
Vertical rails earn their place in narrow bathrooms and tight en-suites. Running the bars up rather than across means more hanging points per metre of wall, which makes them a better fit where a ladder simply won’t sit without crowding a door, mirror or vanity. Shop all vertical rails here.
Horizontal bars suit bathrooms where wall width isn’t the constraint, but height is. Think of a low window or sloped ceiling. A single or double bar gives you drying space without needing the full wall space. If you’re after more of a statement look, stack 2 of 3 horizontal bars vertically to hang multiple towels. Shop Horizontal Rails here.
Floorstanding rails are the answer when you have little or no space on the walls, and they give you the same heated drying function as a wall mounted rail.
None of these are the ‘correct’ choice in general. The right one is whichever best suits your bathroom layout, wall space and style.
How Much Does It Cost to Run a Code Interiors Heated Towel Rail?
Code Interiors heated towel rails are among the cheapest appliances to run in your home. The exact cost will depend on the size, but at New Zealand’s average power price of about 39c per kWh, most cost only 2-6 cents an hour. Used with the included Goldair power-saving timer for a few hours’ morning and night, that’s roughly 10-30 cents a day.
Frequently Asked Questions:
Q: Will a heated towel rail blow out my power bill?
A: Not with a timer. Running costs range from roughly $44 per year on a scheduled timer, compared to $260-$310 per year when left on continuously. See the real numbers above in our table for Code Interiors heated towel rail range.
Q: Is it safe to leave on overnight?
A: Yes. Heated towel rails are built for long, low wattage runs, overnight use is normal, not risky.
Q: Are vertical rails worse than horizontal ones?
A: No! They’re built for different spaces. Vertical rails suit narrow walls and smaller bathrooms, while horizontal suits wider walls with more towel volume.
Q: Do I actually need one, or is it just a nice-to-have?
A: In humid Auckland bathrooms, it’s more than just comfort! It keeps towels dry which helps keep mould and mildew from setting in.
Q: Why do some heated rails feel warm at the bottom and cool at the top?
A: Usually an undersized or poorly placed element, this is typically seen on lower end or cheaper heated towel rails.
Q: Can I install a heated towel rail by myself?
A: No, it is not recommended. Elite recommends that all heated towel rails are to be installed by a qualified electrician.
In short: a heated towel rail isn’t one thing doing one job. It’s the timer helping keep your power bill under control. The element of warming your towels evenly instead of leaving cold patches, the spacing of bars being built for how you actually hang towels and the style that suits your space. Get these four right and the ‘warm towel’ part takes care of itself.
