A Simple Way to Warm a Carpeted Room
Undercarpet heating fits between the underlay and the carpet, making it one of the least disruptive electric floor heating options for a bedroom, living room, or study. The heating mat is foil-based for even heat distribution, and once it’s in, there are no protruding cables or hardware to see or feel — it’s pet and child-friendly, and 100% waterproof, so everyday spills aren’t a concern. The flexible core wire is built to withstand heavy furniture and everyday foot traffic when installed correctly.
Fitting the system alongside a new carpet is straightforward: an electrician pre-wires the power source, the heating mat is laid, the carpet goes down over the top, and the electrician then connects the thermostat — all part of a standard carpet-laying process, and every installation is protected by an RCD (Residual Current Device). While Warmup’s undercarpet heating can be installed yourself, using a fully qualified installer means you get the full benefit of the 5-year product and installation warranty.
The system runs silently, produces no dust or odour, and doesn’t dry out the air the way some heaters can — which is why it’s recommended by health professionals as a sensible option for asthma sufferers. With a programmable thermostat handling zoning and scheduling, undercarpet heating switches on only when it’s needed, so you’re not paying to heat a room you’re not using. As an example of typical running costs, Warmup has estimated that heating an average 10m² room for 6 hours a day costs in the vicinity of $2 a day at a rate of 26c/kWh — though your own costs will depend on room size, insulation, and your power plan, so it’s worth asking your local distributor for a project-specific estimate.
Every Warmup undercarpet heating mat and control is approved and certified to New Zealand and international standards, and comes with a 5-year warranty.

Undercarpet Heating FAQs
A: A professional electrician is required to set up the power supply and to link the thermostat after the mat is installed. Laying the mat itself is done as part of the normal carpet-installation process, so the whole job is often completed in a single visit when your carpet layer and electrician attend together.
A: Undercarpet heating is most straightforward to fit alongside a new carpet installation, since the mat, underlay, and carpet go down in one continuous process. It’s also possible to retrofit beneath existing carpet by lifting it, laying the mat, and re-laying the carpet over the top.
A: Yes. The heating mat is 100% waterproof, and every installation is protected by an RCD, so everyday spills and carpet cleaning aren’t a safety concern.
A: The mat’s core wire is flexible and designed to cope with heavy furniture and everyday foot traffic when the system is installed correctly.
A: As a general guide, Warmup has estimated running costs of around $2 a day to heat an average 10m² room for 6 hours, based on a 26c/kWh rate. Actual costs depend on your room size, insulation, and power pricing, so it’s worth requesting a running-cost estimate for your specific project.
A: Warmup’s undercarpet heating mats and controls carry a 5-year warranty. You’ll get the full benefit of the product and installation warranty when the system is fitted by a fully qualified Warmup installer.
