Infrared heating

[edit] Introduction

As gas and oil heating will 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.

[edit] Optimal room climate

Infrared heaters can 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.

As infrared heating is direct heat radiation, occupants will perceive the room to be 2 to 3 degrees warmer.

Due to the even temperature distribution in the room, there are almost no air movements caused by the heating and therefore no dust turbulence. Since IR heaters do not dry out the air either, it remains fresh and almost dust-free, which is particularly beneficial for people who are sensitive or have allergies.

[edit] Balanced temperature field

Infrared heaters focus on walls, ceilings, people and furniture and not air. The heat is stored in the thermal mass of 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. During usage the panels will not necessarily be running constantly for the heating period when thermostats are used (see below).

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.

[edit] 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.

[edit] High radiation efficiency and low warm-up phase

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.

[edit] No heat loss and cost savings

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 for reducing heating costs.

An added cost benefit with infrared panels is that a system can be built up over a period by buying one panel at a time, gradually creating a bespoke system for the building.

Infrared heating panels do not require maintenance and can run efficiently for up to forty years.
