Five issues that can affect ductwork

Whether you’re planning to renovate an existing HVAC system, retrofitting into an existing building, or installing as a building is constructed, there are a range of issues that can affect the function and efficiency of the system.

Ensuring you don’t fall foul of these issues can help your HVAC system work efficiently, ensuring that energy is not wasted in heating the building. As found by the major climate science bodies across the world, more needs to be done globally to cut carbon emissions and halt global heating, and efficient heating systems are a must.

Use of non-standard configurations

There are tried and trusted ways in which an HVAC system can be installed within a building. Using a radial system, for example, places the main heating unit in the centre of the system, with ductwork emanating from this point in a similar fashion to the spokes on a wheel, and is known to be effective.

Whether installing, renovating or maintaining an HVAC system, all manner of spiral duct and ductwork parts are available from suppliers such as https://www.dustspares.co.uk/ductwork-parts/galvanised-ducting/galvanised-steel-spiral-duct.html

Use of incorrectly sized ducts

If your ducts are too small, it will be impossible for enough hot air to get through your system in order to heat the building effectively. Conversely, ductwork which is too large will reduce the efficiency of a system, wasting hot air, energy and ultimately money.

Not enough return ducts

It is vital that an HVAC system contains both send and return ducts, so that all rooms which receive heated air are able to return air to the heating unit. This air is then conditioned again in order to maintain the efficient working of the system.

Ducts in wrong places

Ductwork which is placed in areas which do not receive heat can cause efficiency issues. Ducting in cool areas can cause energy loss as heat can be lost substantially through the thin walls of the ductwork.

Loose fittings

Ductwork can cause energy loss if it is poorly or improperly fitted. Ensuring all sections fit together without air loss and with no gaps is vital to keeping the system efficient. For a better fit, all joins between sections of ducting should be sealed with tape or mastic. Insulation can help reduce heat loss further.

Avoiding these issues can greatly improve the efficiency of an HVAC system, helping to ensure great value for money.
