Kiertoilmalämmitys

Kiertoilmalämmitys, also known as forced-air heating, is a central heating system that circulates heated air throughout a building. The system typically consists of a furnace or heat pump, a blower fan, and a network of ducts. The furnace or heat pump heats the air, which is then propelled by the blower fan through the supply ducts to various rooms in the building. Vents or registers in each room allow the heated air to enter the living space.

After circulating and warming the rooms, the cooler air is drawn back into the system through return air ducts. This return air is then filtered to remove dust and other particles before being reheated by the furnace or heat pump and recirculated. This continuous cycle ensures a relatively uniform temperature distribution throughout the building.

Kiertoilmalämmitys systems are common in many residential and commercial buildings due to their ability to heat spaces quickly and their integration with air conditioning systems, as the same ductwork can often be used for both heating and cooling. The efficiency of the system depends on factors such as the insulation of the ducts, the effectiveness of the furnace or heat pump, and the proper sealing of the building envelope to prevent heat loss. Regular maintenance, including filter changes and system inspections, is important for optimal performance and air quality.
