If buildings could talk, they would ask for Infrared
Reduction of Condensation
Convection heating works by warming the air around the heater, which creates convection currents that carry the warmth around the room. Warm air has a high relative humidity and when it meets a cold surface, condensation will occur. This increases the likelihood of mould, wood rot, and salt damp or flaking paintwork.
In contrast, Infrared warms the surfaces of objects without warming the air. The relative humidity in the air remains low and when the air meets a warm surface, condensation does not occur.
This is one of the primary benefits to buildings of Infrared Heating. For similar reasons our heaters are also particularly well suited to use in bathrooms, our mirror and glass towel rail heaters will heat the bathroom whilst reducing the likelihood of damp and mould.
Reduction of existing damp
Water absorbs heat specifically well at 3 microns and lower which is the range Herschel far infrared heaters operate at. The infrared from the heater will begin to warm the masonry of a building. When masonry is damp, it absorbs and emits infrared poorly and air circulation actually needs to be encouraged to remove the evaporated water vapour. As masonry dries out, the thermal reflectivity of the room also improves. This is because water in damp masonry initially absorbs the heat and does not emit the warmth back into the room, whereas dry masonry re-emits well.
Our infrared heaters help to dry walls and plaster and preserves paintings and fabrics, which makes it particularly useful for preservation of historical buildings.
Infrared heaters such as the Herschel Advantage range can also be used for flood recovery purposes. Far Infrared is better absorbed by the wet masonry over time and dries from the inside out. Hotter heaters such as quartz and gas blowers are less efficient driers, because their harsher heat flash-dries the surface of the wall, creating a “skin” under which bubbles of water vapour then form, causing blistering of the surface of the masonry.
