Heating System With Hot Air Devices (Thermo Block)

Heat is obtained by firing the natural gas in these systems. After that this energy is used to heat the room or ambient. These devices are called as hot water producer. When the device is operated, firstly exhaust fan which is essential air provider to the combustion room is activated. Also, burnt gasses are exhausted by means of exhaust fan. Convection fan is activated automatically when  Heat exchanger temperature is appropriate degree and it blows the air to the heat exchangers. The air which connect to the hot surface is heated and it is blowed to the ambient. The temperature differences (∆T) between sucked and blowed air is 30 - 40 ^oC. Hot air producers can be produced in 3 types depending on the properties of burning and fan systems, on/off, step or modulated type. The efficiency of ON/OFF and step systems area around 90% and the efficiency of modulated devices can be until 96%.

Hot Air Blower Type Devices:

1. Standard type hot air blower:

These devices are mounted to heated environment and the ambient temperature is heated and the heated air is blowed to the ambient again. They cannot be connected to the channel and the clean air can not be taken from the outdoor. Generally, the convection fan is an axial type.

2. Channel Type Hot Air Blower:

The air pressure output of this system is higher than standard type hot air blower so they can be connected to the channels. 100% fresh air can be taken from the outside to be operated this system. In addition to that partial fresh air can be heated by mixing to indoor air as partially. These systems have various durable model that can be mounted indoor and outdoor.
