Undertile Heating

Electronic Floor Heating

Warmup’s custom-laid heating elements allow full coverage of the floor, making tiles warm, attractive and practical all year round.

As the heating solution becomes part of the floor, with no hot or moving parts, you can still enjoy an uncluttered home, as well as a maintenance-free heating system. This clean, silent and odour-free heating solution will not dry out the air or aggravate allergies.

While we recommend coverage of 50-60% of the floor area, up to 100% of the available floor area can be covered. The cable is extremely strong and has high electrical and mechanical strengths. The strong outer insulation is highly resistant to chemical attack. During installation this cable is covered with a resin coated fibreglass re-enforcing mesh, designed to protect the heating cable and add strength to the screed layer and tile adhesive. Best of all, our heating cables can be installed on new or existing floors.


Warmup heaters can be fitted beneath any type of ceramic, porcelain, marble or slate tiles.


A thin, self-levelling screed is poured over the heating system, to bond it to the subfloor and protect the cables from tiler damage.


A fibreglass resin coated mesh is laid over the heating elements to protect the cable and strengthen the screed.

Heating Cables

Our undertile heating cables are factory tested at 5000 volts, to ensure safety and longevity. The teflon coated cables are extremely thin, minimizing the overall change in your floor height.


The subfloor should be smooth, level and strong, to ensure a good bond between the tile adhesive and heating system.


Warmup undertile heaters are safety tested and are completely waterproof. It is encased in a tough ETFE insulation, which is mechanically tough, has excellent dielectric strength and is resistant to alkali chemical attack in concrete.


Warmup components have the benefit of over 30 years of European technology for applications that demand high flexibility, continuous operation at high temperatures and long working life.


Discreetly hidden from view, these thin heating elements lie hidden directly under the tiles. There are no visible elements or radiators, no summertime storage problems.

Tile Type

Under any ceramic, porcelain, marble and slate, tiles.


While Warmup heaters have been designed to never overheat - and may be left on continuously - timers and thermostats are available as optional extras for additional control.


The system must be installed by an installer who is certified by Warmup, to ensure the full lifespan of the product is enjoyed.


This is not in-screed heating, and is effective within 30-60 minutes of switch-on. You heat the area you need, when you need it.


A 10 year factory-backed warranty is provided. Warranty forms are issued with each heater.


Undertile heaters installed in bathrooms and wet areas must be protected by an earth-shield. Warmup’s earth-braided undertile heaters are compliant for use in bathrooms and wet areas.


For ultimate control and maximum energy efficiency, we recommend the use of an intelligent Warmup thermostat.
