Saving Energy With Fans and Flues

Saving Energy With Fans and Flues

For the standard operation, a warm air heater will utilise two fans. The first pulling in the cold air from the building and moving it across the heat exchanger, where the cold air is warmed and redistributed via the same fan back into the building, and the second is to exhaust the products combustion into the atmosphere.

The use of fans is essential for industrial heaters, and there are many ways in which they are used.

 With radiant heaters, the fan is located on the opposite end of the burner and creates a vacuum which shapes the flame to burn and transfer the heat efficiently through a small diameter tube.

Fans that reduce stratification 

With rising fuel costs it’s important to discover ways to lower your energy bills, within the workplace, and with over 20% of heat lost through the roof via stratification, this is a loss that can be reduced.


What is stratification?


Stratification is the process of warm air rising and cool air descending, creating an unbalanced temperature within your building, meaning that ceiling height is significantly warmer than working height. Heat is only required for approximately up to 6ft above the ground. This means that your system will be continuously working in order to maintain a comfortable temperature at floor level. By doing this not only does it increase your fuel usage but also increases the amount of carbon that you are releasing into the air.

It is natural for heat to rise, so the way to reduce the heat loss is to invest in energy efficient de-stratification fans.

Thermal de-stratification is the equalisation of the air temperature throughout the building, by taking the heat that would ordinarily escape through the ceiling and returning to ground level where it needs to be, this significantly reduce your heat loss through the roof.
De-stratification fans are extremely versatile and would suit most industrial or commercial premises, making them ideal for churches, with the characteristically high ceilings this helps to return the heat where required, back down to the pews.
They can also be used to reduce the amount of heaters required, by redirecting the warm air throughout the building, heating any “cold corners” that you may have.
The use of De-stratification fans are advised by the carbon trust to reduce the amount of CO2 emissions.
These fans can be utilised on all industrial heating equipment, such as radiant heaters, suspended units or floorstanding cabinets.

It’s not only de-stratification fans that can save money for your business. Some manufacturers such as Combat, are utilising burners that provide a high efficiency fan ventilation system that could achieve over 50% better fan performance, and also allowing the installer to utilise a longer, smaller diameter flue option, which can be installed horizontally, which could save you money on installation costs, due to the reduced roof penetration and reduced material costs.
