UNDERFLOOR HEATING & ORANGE GAS HOSE

G1 Distribution imports and wholesales a complete range of hydronic (liquid-based) heating materials across Southern Africa. As the most popular and cost-effective radiant heating solution, hydronic systems circulate heated water through tubing beneath the floor, delivering efficient and consistent warmth.

Underfloor heating uses the floor surface within a home as a heat emitter.

Hot water pipework loops are embedded into the floor construction as part of the ‘wet’ central heating system.

Due to the large surface area of the emitter, water can be circulated through the distribution system at a relatively low temperature (around 40°C)

A larger proportion of the heat emitted through underfloor heating is utilised to provide warmth to people directly and relatively less heat is used to warm the air first.

Underfloor heating loops should have no joints, with all connections for maintenance located above the floor finish at the manifolds, making the installation relatively robust against leaks.

Underfloor heating requires hot water input at relatively low temperatures from the main heat source, typically 35 to 45°C. This can be achieved either at source or externally through mixing valves. 

 

Heat pumps extract heat from low-temperature sources like air, ground, or water and boost it to a higher temperature using electricity. Their efficiency, measured by the Coefficient of Performance (COP), improves when the temperature gap between the source and the output is small. This makes heat pumps ideal for underfloor heating systems, which require lower supply temperatures.

Underfloor hydronic floor heating is the way to go.

The pipe, fittings and materials that G1 offer to this industry uses low-temperature water to heat the floor, objects, and people, and the heat can be adjusted from one room to another.

The material G1 offers to the market can hook-up to various heat sources. Heating source can include solar panels, gas burners, oil burners, heat pumps, and so forth.

The picture below will indicate what to expect what is in the box. This will be the underfloor heating manifold and parts. The actuator is also available from us but is excluded from the box.
