What is the difference between electric vs water underfloor heating systems in South Africa?

Electric vs Water Underfloor Heating Systems

The main difference between electric underfloor heating vs water underfloor heating systems lies in how they generate and distribute heat.

Electric underfloor heating uses heating mats or cables installed beneath your flooring. It is cheaper to install (around R1,000 – R2,500 per m²) and ideal for smaller areas like bathrooms, kitchens, or single rooms. It heats up quickly, making it convenient for targeted heating. However, the running costs can be higher, averaging R400 – R1,200 per month depending on room size and usage.

Water underfloor heating systems (also known as hydronic or wet underfloor heating) circulate warm water through pipes installed under the floor. This type is more expensive to install (about R2,000 – R3,800 per m²) and better suited for large homes or open spaces. Although the upfront cost is higher, water systems are significantly cheaper to run over time, costing as little as R300 – R800 per month when connected to energy-efficient boilers, solar, or heat pumps.

In summary:

• Electric underfloor heating = lower upfront cost, higher running cost, best for smaller spaces.
• Water underfloor heating systems = higher upfront cost, lower running cost, best for larger homes.

Both systems are safe, durable, and add value to homes in South Africa, but the choice depends on your budget, floor size, and long-term underfloor heating needs.
