Traditional convection systems warm the air and circulate it around rooms. While well understood, this approach has disadvantages:
- Radiator energy loss: radiators are typically sited on external walls and under windows in order to reduce the heat gradient across a room – to avoid cold spots. Unfortunately, this means that the hottest part of the heating system is located next to the coldest external surface, thereby maximising the heat loss through the wall and the window.
- Slow warm-up: the radiator and the air take a long time to heat, so the heating is turned on a long time before the room is to be occupied.
- Fast cool-down: Poorly insulated or draughty properties can suffer multiple air changes every hour – so warm air is lost quickly.
In contrast, NexGen covers the ceiling, so all parts of a room are warmed. NexGen’s infrared energy passes through the air and heats our skin directly and quickly. Infrared therefore isn’t so sensitive to leaks of warm air.
Everything – and everyone – emits far infrared
Infrared is emitted by every object which is above a temperature of absolute zero (-273oC) – and since everything on earth is warmer than that, every object in our world, living or not, emits infrared energy.
The amount and type of infrared energy emitted depends on the temperature of the object and how big a surface area it has. Hot items emit a greater quantity of higher energy infrared, and cooler items emit lower quantities of lower energy infrared. We call this lower energy infrared ‘far infrared’ because it is far away from the higher energy levels that are associated with visible light. NexGen uses this lower energy, far infrared.
As an aside, we humans constantly emit infrared: each human emits around 100W of infrared – enough energy to power a typical TV.

Nexgen delivers highly efficient warmth using low-carbon energy, and provides a cost-effective, comfortable working environment in places where, to date, this has been impossible.
