Energy savings using Infrared Heating

The comparisons made to study energy savings, were made against Redwell Infrared Heating Systems on different sized properties using a variety of heating methods.

The results showed quite conclusively that up to 70% less energy was required when heating using Infrared – to achieve the same level of heat as currently used in each home.

Energy-efficiency demonstrated by Redwell Infrared Heaters

Further experiments were carried out, to determine heat-efficiency over time using infra red heat to maintain a constant heat inside, despite changes outside.

With more usual convection-based heating, changes in outside temperature typically require changes in energy inside, to adjust heat accordingly – the larger the change in temperature, the more energy is used (insulation remained the same before and during the experiment).

The tests showed that whilst heating was needed when the outside temperature dropped (insulation was not perfect), the infrared heat energy required to maintain comfort was far lower than standard convection-based heating. Consequently, heating costs during winter may be considered a fraction of those using convection heating.

ROOM 1

Energy Saving Construction

Outer walls: u/value 0.23 W/m2K Windows: u/value 1.55 W/m2K
Heated net area: 12.70 m2 Heated net volume: 30.50 m3
Heat output needed: 451 W

Statistics period from 1.10.2007 – 31.3.2008
Max. outside temperature: 23.2 C Max. wind speed: 65.25 Mph
Min. outside temperature: – 8.10 C Min. wind speed: 0.00 Mph
Average outside temperature: 4.10 C Average wind speed: 5.78 Mph

Energy costs: 208 kWh x 0.10 = £20.80 (room – total heating period)
