The Disadvatages of Energy Recovery Ventilators

Overheating

• Energy recovery ventilators are most commonly used to recover energy leaving the building, and this energy is then used to heat the building. ERVs have a limited capacity to produce cool air in buildings, which can often lead to overheating. Ventilation systems are much more effective than ERVs at regulating a building's temperature and preventing overheating.

Extra Space for Air-Conditioning Units

• Air-conditioning units are also required in most buildings when using a Energy Recovery Ventilator. This allows the internal spaces to regulate their heat more effectively and keeps building users comfortable. The machinery uses more space, however, and building designs may require recessed ceilings to house the pipework.

Lack of Standardization

• Another major disadvantage of energy recovery ventilators is the lack of standardization within the industry. The industry is relatively new, and technologies are being redeveloped all the time. This constant change in the industry can make maintenance and development of the systems problematic, leading to reduced efficiency and increased costs of the machinery. Most contractors also lack the technical expertise and experience to install them.

Cleaning

• Heat Energy Ventilators need to be cleaned more often than other heating systems. Mold and bacteria can grow on heat-exchanger surfaces, causing the system to stop functioning efficiently and leading to its gradual deterioration. Only individuals with specific knowledge of the product should dismantle the system and clean the ERV so that the cleaning process is done properly.
