The floor becomes the emitter
Heating cable runs beneath the whole floor area, so the warm surface is measured in square metres rather than the square centimetres of a radiator panel. A large emitter running gently beats a small one running hot.
How it works · The physics
A radiator warms the air near a wall and hopes it circulates. An electric hamam turns the entire floor into the heat source, so warmth arrives evenly, silently, from the one surface you are actually touching.

The system, layer by layer
Look beneath the floor.
Layer 01
The Kashmiri carpet
Hand-woven wool, the only thing between bare feet and the heat below.
Layer 02
Tile, stone or wood
The finished floor, the only part of the system anyone ever sees.
Layer 03
The heating mat
Self-regulating cable on a fibreglass mesh. Just 5 mm thick, this is the layer doing the work.
Layer 04
Insulation board
Sits under the mat and forces the heat upward instead of letting it sink into the slab.
The mat
Built to be walked on
A full turn around the mat, the cable, the spacing and the coverage that make the floor even underfoot.

The principle
Convection heating warms air and moves it around the room. Radiant heating warms the surfaces and the people directly, the same way sunlight warms you on a cold day without warming the air between. That single difference is where every other advantage comes from.
The screed stores the heat
The cable sits inside a concrete screed layer. Concrete is slow to warm and slow to let go, so the floor behaves like a battery: it charges while the power is on and keeps radiating after it is not.
Nothing is blown anywhere
No fans, no ducts, no draughts. Dust and allergens stay where they are, the air does not dry out, and the room is silent, there is no moving part anywhere in the system.
| Metric | Electric hamam | Radiators & blowers |
|---|---|---|
| Heat distribution | Even across the whole floor | Hot near the unit, cold at the far wall |
| Warmest point | The floor, where you stand | The ceiling, where nobody is |
| During a power cut | Screed keeps radiating for hours | Cold within minutes |
| In the room | Silent, invisible, no floor space used | Audible fans, wall space, visible units |
The control layer
A wood hamam needs someone to feed it. This needs a target temperature. The thermostat reads the floor and the room, then gives the cable only the power required to hold the number you set, which is what keeps a running cost predictable.

Cycling through a full day
OffNOW
The system rests at room temperature. Nothing is drawing power, and the ring sits where the room actually is rather than at zero.
Heating
Full power to the cable until the target is met. This is the only phase drawing the system’s rated load, and on a well-insulated floor it is the shortest one.
Holding
At temperature. The thermostat now cycles the cable in short bursts to replace only the heat the room loses, which is where the running cost quietly settles.
Scheduled
Set it to be warm by the time you are home. The controller works backwards from the target hour and starts early enough for the screed to come up to temperature.
Power cut
The dial goes dark, the floor does not. Stored heat in the screed keeps the room comfortable for hours, which in Kashmir is the entire reason this system exists.
