The Benefits of Proper Ventilation in NZ Tiny Homes



Proper ventilation plays a vital role in maintaining a healthy living environment inside NZ tiny homes. Although these compact dwellings offer numerous advantages, it is extremely important not to overlook the importance of ventilation. Here are various benefits that come with ensuring proper airflow within tiny homes.

  1. Improved Indoor Air Quality: Ventilation helps remove stale and potentially harmful air from inside the home. It circulates fresh outdoor air, reducing the concentration of pollutants such as carbon dioxide, volatile organic compounds (VOCs), and airborne allergens. This can enhance the overall health and well-being of occupants.
  2. Moisture Control: Good ventilation prevents the buildup of excess moisture in the indoor environment. Tiny homes can be prone to condensation and excessive humidity due to their limited space and insulation. Proper ventilation helps to control moisture levels, preventing issues like mold growth, dampness, and musty odors.
  3. Temperature Regulation: Ventilation helps regulate indoor temperature by allowing fresh air to circulate around the home. In summer, it promotes cooling by expelling hot air and introducing cooler outside air. In winter, it prevents stagnant air, reducing the likelihood of cold spots and improving overall comfort.
  4. Odor Removal: Ventilation helps remove unpleasant odors that can accumulate in small living spaces. Whether it's cooking smells, bathroom odors, or pet odors, proper ventilation ensures these scents are efficiently expelled from the home, keeping the interior smelling fresh.
  5. Health Benefits: Adequate ventilation in tiny homes can have numerous health benefits. It reduces the risk of respiratory problems by removing pollutants and allergens from the air. It also helps prevent the growth of mold and mildew, which can trigger allergies and respiratory issues. Additionally, proper ventilation reduces the buildup of harmful gases like carbon monoxide, improving indoor air quality and reducing the risk of poisoning.
  6. Energy Efficiency: Proper ventilation can contribute to energy efficiency in tiny homes. By allowing for natural airflow, it reduces the need for mechanical cooling or heating systems. This can result in lower energy consumption and reduced utility bills.
  7. Comfort and Well-being: Good ventilation creates a more comfortable living environment by maintaining a steady supply of fresh air. It prevents stuffiness and promotes a feeling of well-being inside the home.
  8. Longevity of Building Materials: Adequate ventilation helps prevent moisture-related damage to building materials in tiny homes. Excess moisture can cause wood rot, deterioration of insulation, and corrosion of metal components. By controlling moisture levels, ventilation helps extend the lifespan of these materials.


Which type of tiny home ventilation system should I install?

Compact living spaces often face challenges when it comes to adequate ventilation due to limited space availability. To overcome this issue, decentralised ventilation systems with heat recovery offer an innovative and efficient solution for tiny homes.



As the trend towards smaller living spaces gains popularity, it is essential to develop sustainable and energy-efficient solutions that provide adequate ventilation without compromising comfort or increasing energy consumption. Decentralised heat recovery ventilation systems address these concerns by offering an all-in-one solution.

Our recommendation: Lunos decentralised heat recovery ventilation

Lunos offers a perfect solution for implementing efficient and effective ventilation systems in tiny homes. These innovative decentralised heat recovery ventilation systems are specifically designed to ensure excellent indoor air quality, regardless of the limited space available.

Lunos e²

One highly recommended Lunos product for tiny homes is the Lunos e². This compact unit combines supply and exhaust functions in a single device, making it ideal for small living spaces. 

The e² functions based on the principles of a regenerative heat exchanger. It stores heat energy in a manner similar to a battery during reverse operation, and then transfers this heat to the outside air that is being supplied. The ventilation unit with heat recovery consumes an exceptionally low amount of power, specifically 1.4 Watts during base load operation (equivalent to 0.09 W/m3/h). Additionally, it operates at an almost silent sound level of 16.5 dB(A).

Lunos Nexxt

Another suitable option for tiny home ventilation is the Lunos Nexxt. This decentralised ventilation unit utilizes heat exchanger technology to ensure energy-efficient operation with a heat recovery rate of up to 90%. The Nexxt features an intelligent and compact design that can be easily installed in limited spaces and a maximum standard sound level difference of 56 dB is achieved, making it an excellent choice for tiny home owners. Equipped with advanced sensors, such as humidity and CO2 detectors, this smart ventilation system automatically adjusts its airflow according to the occupants' needs, ensuring optimal indoor air quality at all times.

Lunos ego

The Lunos ego also operates in accordance with the principle of the regenerative heat exchanger. It has a storage element that is filled with heat, similar to the e2 model. However, the ego operates in a more efficient way by using two fans to evenly distribute the supply and exhaust air at the same time. This means that there is no need for a separate unit to provide the necessary airflow.

Furthermore, the Lunos ego can also be switched into an exhaust air mode which discharges a very high flow rate of 45 m3/h, allowing for a swift inflow of fresh air into a room. This mode is particularly useful in areas such as bathrooms or toilets, where quick ventilation is often required.

Lunos Silvento

The Lunos Silvento is a new and improved air ventilation and moisture control solution. It is perfect for bathrooms, laundries, and other areas that need better moisture management or heat ventilation. While it may not be as fancy as other models, it can still be a great addition to a small home's ventilation system, especially in areas where moisture tends to build up.

The Silvento helps to combat rising energy costs and pollution in a space. These fans are known for using very little power because they have been engineered with EC technology. They work efficiently and can be adjusted to have lower airflow - either with intermittent or continuous flow, or both.
