Office ventilation system with a heat recovery

In today’s world, the importance of a healthy, comfortable office environment cannot be overstated. A key component of this environment is the quality of the air that employees breathe. The Prana Recuperator/decentralised MVHR helps to ensure that fresh and clean air is available, regardless of the season or weather conditions.
A well-designed ventilation system with a heat recovery unit brings in fresh air and removes pollutants, unpleasant odours and excess moisture. This helps to reduce airborne contaminants, creating a healthier and more comfortable environment that keeps employees happier and reduces the likelihood of respiratory problems.

Clean air and high energy efficiency for your office

The quality of air in a workspace is crucial for the wellbeing and efficiency of those who use it. An effectively planned adequate ventilation system with a heat recovery unit ensures a steady flow of fresh air into the premises, while simultaneously extracting pollutants, unpleasant smells, and excessive moisture. This process helps lower the levels of harmful substances and airborne contaminants, fostering a healthier workspace. Such an environment not only boosts the satisfaction of employees but also minimises the likelihood of respiratory problems, contributing positively to their overall health and productivity.

An office ventilation system with heat recovery works by bringing fresh air into the office while removing stale air, and at the same time, it saves energy by reusing heat. The system has two air streams — one carrying the outgoing stale air and the other bringing in fresh air from outside. These streams pass through a heat exchanger, where the heat from the stale air is transferred to the incoming fresh air. This process warms up the fresh air before it enters the office, meaning less energy is needed to heat the office. The result is fresh, clean air in the office without losing heat, making it energy efficient.

Office ventilation systems with heat recovery systems offer several benefits:

  • Energy efficiency. The system reduces the need for additional heating by capturing and reusing heat from the air extracted from the office. This heat recovery process is particularly effective in colder months when heating demand is higher, ensuring the office remains warm without excessive energy consumption.
  • Improved Indoor Air Quality. Such systems are designed to continuously cycle fresh outdoor air into the office while removing stale, indoor air. This exchange is crucial in reducing levels of indoor air pollutants, such as volatile organic compounds (VOCs), carbon dioxide, and other airborne contaminants. Regularly introducing fresh air is essential in spaces that are densely populated or have limited natural ventilation.
  • Cost Savings. With the reduction in energy consumption comes a corresponding decrease in energy costs. Offices equipped with heat recovery ventilation systems can see a significant reduction in their heating bills, making these systems a cost-effective investment in the long term.
  • Comfortable Environment. They help maintain a comfortable and consistent indoor temperature. Consistent and efficient temperature control is a key feature of these systems. By ensuring that incoming air is pre-heated (or pre-cooled in warmer months), the system maintains a stable and comfortable indoor environment, which can be crucial for employee productivity and satisfaction.
  • Eco-Friendly. In an era where environmental sustainability is increasingly important, office ventilation systems with heat recovery offer a greener solution. By reducing overall energy consumption, these systems lower the carbon footprint of the office, contributing to a more environmentally responsible workspace.

Modern heat recovery ventilation systems often come with advanced control options, allowing for precise regulation of indoor air quality and temperature. This can include remote control, programmable settings, and integration with building management systems.
Office ventilation systems with heat recovery are a cornerstone of modern, efficient, and sustainable building design. They not only contribute to a healthier and more comfortable working environment but also align with the broader goals of energy efficiency and environmental responsibility. As we move towards more sustainable practices, these systems are likely to become standard in office buildings across the UK.


Yes, you can add a mechanical ventilation system to an existing building, but how easy or hard this is depends on the building’s design and current ventilation setup. It’s a good idea to talk with our heating and ventilation expert to see if it’s possible and what it would involve.

Installing office heat recovery units offers several benefits:

  1. Energy Efficiency. They save energy by reusing heat from expelled air to warm incoming fresh air.
  2. Improved Air Quality. These units ensure a constant supply of fresh air, reducing pollutants and improving overall air quality.
  3. Cost Savings. Reduced energy usage leads to lower heating and cooling costs.
  4. Comfortable Environment. They help maintain a comfortable and consistent indoor temperature.
  5. Eco-Friendly. By using less energy, these units are better for the environment.
