Hydronic underfloor heating is a heating system that uses warm water circulated through pipes installed beneath the floor surface. The heated water gently warms the floor, which then radiates heat evenly throughout the room. This system is energy-efficient, provides consistent comfort, and can be powered by a variety of heat sources such as gas boilers, heat pumps, or solar systems. It is especially popular in South Africa for homeowners seeking a modern, cost-effective, and long-lasting home heating solution.
