While a thermostat controls the operation of an HVAC system, homeowners can also install a humidity control system, air purification devices, and other accessories to help improve indoor air quality. The earliest heating and cooling systems were invented in the Middle Ages, and the idea is attributed to John Evelyn. But in the nineteenth century, the Cistercian monks revived the concept, using river diversions and indoor wood-fired furnaces. Their method was first used in the Royal Monastery of Our Lady of the Wheel, which was founded in 1202 on the Ebro River.
The ductless mini-split system is a system that can be installed into different zones of a home. It has up to four indoor air handling units per outdoor unit. These systems are ideal for small homes, apartments, and commercial buildings, as they do not require a lot of space. In addition, ductless systems can work in conjunction with ducted HVAC systems. Once installed, you can expect the unit to run efficiently and quietly, and will not cause any problems.
Among the many heating and cooling options, the electric furnace is an attractive option. It combines the functions of a heat pump and an air conditioner with a fan coil. The blower moves air over one to five resistance coils and elements. The electric heaters are usually regulated by a limit controller to prevent overheating. The thermostat also has a control interface to control temperature. If you choose to install an electric heater, make sure to choose a system with air purifiers or UV lamps, as well.
