As gas and oil heating are likely to be phased out over the next few years, an alternative method of heating may be necessary. Heat pumps, hydrogen and bio mass could be considered alternatives but the inconvenience of installation, use, and cost may preclude them from being a viable replacement for some consumers.
Infrared heating (IR heating) may offer an alternative.
Infrared heaters use less energy than traditional heating by gas, oil or other forms of electric heating. Traditional heating warms the air providing air circulation but as a result gives away a lot of thermal energy. Additionally, there are energy losses of between 30 and 40 per cent caused by room ventilation.
 Balanced temperature field
Infrared heaters focus on walls, ceilings, people and furniture and not air. Therefore, the heat is stored in those objects and provides heat for a longer period. Consequently, infrared heaters typically need only be working for around 5 hours a day to cover a heating period of 24 hours. It does of course depend on the individual heat demand which varies from property to property however, in new builds, it should be consistent with the better insulation. Infrared heaters ensure room temperature control resulting in a balanced temperature field in every room.
 Extra comfort with radio thermostats
Radio thermostats ensure that heating can be controlled as required. The IR heating system is communicated with by radio link. The thermostat consists of a transmitter and a receiver which is installed between the heater and socket. The thermostat typically provides for up to 6 different temperature changes a day and can be customised for every day of the week. It follows that with its targeted settings energy consumption and costs can be reduced.
Radiation efficiency indicates how much of the heat radiation is emitted by a heat wave heater in the room. The total radiation efficiency of IR panels has been measured by the Technical University of Stuttgart at 71%. After just 4 minutes the IR panels reach a surface temperature of 60 degrees and achieve the required room temperature in a very short time. Despite the rapid warm-up phase IT prevents the risk of burns if the panels are touched.
Infrared heaters generate the required heat directly in the installation room thus preventing heat loss which other heating systems may suffer. IR heaters with their sophisticated technology and special powder coating provide infrared reflecting insulation. This combination ensures better utilisation of thermal energy making them more effective and efficient and reducing heating costs.
