Underfloor Heating Auckland
Warm tiled floors for Auckland homes. Electric under-tile heating installed as part of the tiling, in bathrooms, kitchens and living areas.
Auckland under-tile heating
When you need underfloor heating
Nobody forgets the first winter morning they stand on a heated tiled floor. Tiles are the best-looking, hardest-wearing floor you can put in a bathroom or kitchen, but in an Auckland winter they’re cold underfoot. That is the one complaint we ever hear about them. Electric under-tile heating fixes it. A heating mat or cable goes into the floor build-up as we tile, a thermostat with a floor sensor runs it, and the tiles themselves become the radiator.
Most people add it during a bathroom renovation or a new build, because that is when the floor is open and adding it is easy. It is comfort heating for the rooms you tile. Warm underfoot, on a schedule you set, and invisible once it is in. The best time to think about it is before the tiles go down, which is exactly when we’re there.
What we handle
Under-tile heating we install
We install electric under-tile heating as part of the tiled floor build-up, so the heating and the tiles are designed together. Here is what that covers.
Bathroom underfloor heating
When a bathroom gets renovated, the heating goes in at exactly the right moment: after the waterproofing, before the tiles. A warm bathroom floor on a June morning is the upgrade people rave about most, and in a wet area it helps the floor dry faster too. We lay the mat across the open floor area, keep it clear of the fittings, and tile straight over it.
Kitchens and living areas
Picture a tiled kitchen floor in July. Bare feet, first coffee of the day. Kitchens and dining areas take under-tile heating just as well as bathrooms do, and so does any tiled living space. In bigger rooms it makes tiles a genuine alternative to carpet for warmth. We plan the mat layout around the cabinetry and the island so the heat goes where feet actually land, not under the fridge.
How the system goes in
What is actually under a heated tiled floor? From the bottom up: insulation board so the heat goes into the room instead of the slab, then the heating mat or loose cable, then self-levelling compound or the adhesive bed to protect it, then the tiles. Mats cover open floors quickly. Loose cable lets us work into awkward shapes. The whole build-up adds only a few millimetres, and we manage that height at doorways and thresholds.
Thermostats and running it
Most people run underfloor heating for a couple of hours in the morning and evening, not all day. A thermostat with a floor sensor makes that automatic. It reads the actual tile temperature and holds it where you want it, on a schedule. What it costs to run comes down to the insulation under it, the size of the room and how you programme it, so we set it up properly and show you how to use it before we leave.
Wet areas and waterproofing
From there it ties into the wet-area work we do every week. In a bathroom the heating sits above the waterproof membrane, with every penetration sealed, so the heating and the waterproofing never compromise each other. Because we do both, the layers are designed as one floor. There is more on the membrane side on our waterproofing page.
Retrofits and the electrical side
We don’t do the wiring. And you should be wary of anyone who says their tiler does. The element goes in as part of our tiling work. The final connection is the electrician’s job, along with the RCD protection and the Certificate of Compliance that New Zealand’s electrical rules require. We work in with your electrician, or recommend one, and we resistance-test the element before, during and after tiling, so if a cable is ever damaged it is caught while it can still be fixed.
Underfloor heating across Auckland
We install under-tile heating wherever we tile, right across Auckland. South and east through Papakura, Takanini, Manukau, Howick, Pakuranga and Botany. Central in Remuera, Ellerslie, Epsom and Mount Eden. West to Henderson and New Lynn, and over the bridge on the North Shore.
Heating almost always goes in alongside a tiling job, so if we’re already tiling your floor, adding warmth to it is a small step. Not sure we reach your street? Ask. The answer’s usually yes.
How it works
What to expect
Plan and quote
First, the plan. We look at the room, work out the heated area and the mat or cable layout, and give you a clear written quote with the heating included alongside the tiling.
Prep and insulation
Then the base. Substrate made sound, waterproofing in wet areas, insulation board down so the heat goes up into the tiles rather than down into the slab.
Heating and leveller
Next the element. The mat or cable goes in and gets resistance-tested, then protected under self-leveller or the adhesive bed. Your electrician wires the thermostat and certifies the connection.
Tile and hand over
Last, the tiles go on and we test the element again once we’re done. You get a warm floor and a programmed thermostat, and a walk-through before we leave.
Done properly
Why choose Hi Tech Tiling
Under-tile heating lives or dies on the installation, and the installer is the tiler. Because we do the heating, the waterproofing and the tiles as one build-up, nothing gets lost between trades. The insulation board is planned with the membrane. The element is planned with the tiles. And the element is resistance-tested at every stage, so a damaged cable never gets buried under a finished floor.
We’re honest about what it is too. Under-tile heating is comfort heating for tiled rooms, not a whole-home heating system, and if you want the full efficiency picture, EECA’s home energy guidance covers how the options compare. Auckland homes are damp and cool in winter more than they’re freezing, which is exactly the gap warm tiled floors fill. We stand behind our workmanship, we’re local, and the same crew that tiles your floor installs the warmth underneath it.
Good to know
Underfloor heating questions, answered
Does underfloor heating need an electrician?
Yes, always. We install the element as part of the floor. Your electrician makes the final connection, adds the RCD protection and issues the Certificate of Compliance, because New Zealand’s electrical rules demand it. Anyone offering to do the lot with no electrician involved is a red flag.
Can it go under any tile?
Under almost any, yes. Porcelain and ceramic conduct and hold heat well, and so does stone, which is why tiles suit underfloor heating better than most floor coverings. Large-format tiles are fine too. What matters is full adhesive coverage and protecting the cable while tiling, which is our job.
How long does a heated floor take to warm up?
Depends mostly on what is under it. With insulation board beneath the element, a tiled floor comes up to temperature in well under an hour. Without it, the slab steals the heat and it can take several times longer. That is why we treat insulation board as part of the system, not an optional extra.
Is underfloor heating expensive to run?
It comes down to how it is installed and how you run it. Insulation under the element makes the biggest difference, then the size of the room, then how you programme the thermostat. It is comfort heating for the rooms you use, warm mornings and evenings, not something you would heat a whole house with.
Can you add underfloor heating to my existing tiled floor?
Only by re-tiling. The element has to live inside the floor build-up, under the tiles, so it goes in when a floor is being tiled or re-tiled. If a renovation is on the cards anyway, that is the moment. The extra floor height is small, a few millimetres, and we manage it at doorways.
What happens if the cable gets damaged?
Caught early, it is fixable. This is why we resistance-test the element before, during and after tiling. If a trowel ever nicks a cable, the test shows it immediately, while the floor is still open. A cable that tests clean after tiling is protected under the leveller and the tile, and there is nothing left to damage it.
