Warmset GOLD heating mat 24 V (0.5–3 m²) – infrared electric underfloor heating
Warmset GOLD 24 V is a modern infrared electric underfloor heating mat designed for comfortable and efficient floor heating in both new-build and renovation projects. Thanks to its slim construction, it is ideal where minimal floor height increase is required.
The mat is installed directly into tile adhesive or a self-levelling compound. The insulation is made of a durable polyamide film with high thermal resistance. Depending on installation conditions and control, this technology may help reduce energy consumption by up to 30%.
Key benefits
- 24 V supply voltage – safe solution for special installations
- 150 W/m² output – a versatile option for most rooms
- Infrared heating technology – even heat distribution
- Installation in tile adhesive or self-levelling compound
- IPX7 protection class – suitable for wet areas
- Certified according to EN60335-2-96 (BS7671:2008 welding quality requirements)
Recommended applications
- Bathrooms, toilets
- Kitchens, hallways
- Living areas as supplementary or primary heating (depending on insulation)
- Renovation projects where floor height is limited

- Use with a suitable thermostat / controller.
- Always follow the manufacturer’s instructions and local electrical regulations.
Why choose a 24 V heating mat instead of 230 V?
24 V heating mats are a low-voltage solution that is often selected for higher electrical safety. This is especially relevant in wet areas (bathrooms, SPA), children’s rooms, or projects where enhanced safety standards are required.
Main advantages of 24 V systems
- Higher safety: low voltage significantly reduces the risk of electric shock.
- Ideal for wet areas: a very good choice for bathrooms, SPA and similar environments.
- Lower risk if damaged: if the mat/cable is accidentally damaged, the consequences are usually less severe compared to 230 V systems.
- Suitable for special projects: modular homes, mobile units, boats, or facilities with strict safety requirements.
- Centralised power supply: one transformer can power multiple zones (when correctly sized).
Things to consider
- A transformer is required: 24 V mats need a transformer / power supply unit, which adds cost and requires installation space.
- Higher current: for the same heating power, a 24 V system operates with higher current (A), so cable sizing and distances must be planned correctly.
24 V vs 230 V – key differences

| Safety |
Very high (low voltage) |
High, but higher shock risk |
| Wet areas |
Excellent choice |
Suitable, but requires strict protection |
| Transformer required |
Yes (mandatory) |
No |
| Installation complexity |
Moderate (additional component) |

| Best use cases |
Bathrooms, SPA, special installations |
Standard homes and commercial spaces |
Tip: choose 24 V when safety and special installation requirements are the priority. Choose 230 V when you want a simpler setup without a transformer, especially for larger areas.
