About ThermoSphere

ThermoSphere is the British heating brand that refuses to follow convention. Designed and manufactured in Great Britain, every ThermoSphere system benefits from more than 25 years of heating engineering expertise and a relentless focus on cable reliability.

The signature TwistedTwin™ cable is a twisted dual-conductor construction, a deliberate departure from the parallel-conductor designs used by most competitors. Twisting the conductors cancels electromagnetic fields to undetectable levels, eliminates cable stress at the point of manufacture, and dramatically reduces the risk of fatigue failure after years of thermal cycling. The result is a system rated IP68 (submersible), fully earthed, and trusted in 30+ countries.

From the heat-ready membrane to the dual-conductor foil, every ThermoSphere product is built to outlast the floor covering it sits beneath. Backed by a Lifetime Guarantee and installed exclusively by trained professionals, ThermoSphere is the choice for premium residences, heritage renovations and architect-led commercial projects across India and beyond.
