Project Black: The Future of Commercial Heating.

Supplies energy efficient soft radiant heat directly to users where they need it most.

Designed for open plan offices where shared environments can often mean a conflict in heating and cooling.

People all experience heat differently. What feels warm to one person is too cold to another. This results in space heating that never quite works for everyone. This can often lead to expensive call-outs to adjust major HVAC systems to increase the temperature which can also result in a huge increase in energy consumption within a building.

For example, Anna might feel a chill whilst working stationery at her desk, while Peter who just walked in from a hill walk is too hot. Anna puts in a request with the services manager to have the heating turned up. Then Peter asks for cooling or wants to open a window. As facilities experts we see this conflict all the time.

Our unique design of infrared local heating uses a very low wattage, low temperature panel to deliver 'direct heat' to occupants. This empowers them to take control and become responsible for their own heating.

It's more energy efficient as the panel does not waste energy heating the air. It transmits direct heat via radiant waves. This gently warms occupants laps and legs, which in turns warms the femoral artery, allowing the person’s entire body temperature to rise to a comfy level when sitting stationery.

Optional extra wifi controllability

The occupants can control the heating power and can select run times via the Efergy ego smart phone app. The smart socket (an optional extra that can be supplied with each desk heater) allows users to activate the heater when they are on their way to the office, set timers, monitor energy use and set a count down timer to ensure it is switched off after a chosen period)


  • Reduce maintenance call-outs for heating complaints

  • Heats people directly and efficiently for only 135 watts per hour (that’s about 3.5cents to run per hour, based on a 25c per kw electricity charge)

  • Save energy by heating occupants directly where they mostly need the heat

  • Ideal for draughty offices or open shared spaces

  • Silent, no annoying blown air that dries people out

  • Simple on/off control

  • Remove old 2kw plug-in heaters that are not energy efficient (these are often responsible for huge increase in peak energy costs)

  • No moving parts to service or clean

  • Carbon crystalline offers 98% efficiency

  • Does not burn oxygen resulting in a healthier air that doesn't put people to sleep

  • Easy to install under the desk, or on the modesty panel.

Don't waste energy heating air in large open spaces.....Heat people instead.

We have been doing it wrong for years when it comes to heating commercial environments. There has been so much focus on heating the air to warm occupants and maintain body temperature. However, air is an insulator and not always the best way to heat stationery occupants. Warm air rises (heat stratification), so the expensive heat is often collecting near the ceiling where it does not effectively heat occupants below.

People feel the cold mostly when they are sitting still. The blood in their lower body becomes cooler and they feel the draughts and cooler air that sinks towards the floor level.

The problem:

We’ve assessed heating at a local University where some students wanted the heating on high, whilst others felt far too hot. We also interviewed staff and found that most people felt the coldest when stationery at their desk (especially in older buildings or where they are sitting near external walls and glazing) 

Many had brought their own 2.4 kw convection heaters to run at their desk, even though the central heating system was active. This was using a tremendous amount of energy and the facility was being fined for Peak Demand charges by their power provider every winter.

The below thermal image is an example of warm air rising from a typical cheap plug-in convector heater. Heated air was rising straight to the ceiling. As a result, occupants who brought in non-efficient heaters, pushed the power bill sky high.

Example of heat rising to the ceiling from a cheaper convector heater. This wastes energy and causes discomfort via drafts as cooler air in drawn to towards the heater (as heat rises in the room)

The solution:

We believe direct tailored 'local' heat is the way forward. This gives occupants control and flexibility to maintain their own desired temperature in shared spaces or large building where warm air rises and leaks away.

So we developed a low wattage personal desk heater. This is not a particularly new idea, but one that has often been forgotten. We then set about making sure it transmitted heat via radiant waves (so as not to waste energy heating the air). The result is 'direct' heat where it's most needed for a fraction of the energy use.

As a results heating complaints dropped and the overall ambient air temp could be lowered from 22C to 19C, which reduced power and gas consumption.

Occupants were very happy and found the heat very comfortable as it did not involve 'blown air that drys them out'
