The  Continuous Running Alternate Flow Heat Recovery Fan is a specialised ventilation system designed for habitable areas in homes. 

Here are some key features and information about this product:

  1. Continuous Operation: The fan operates continuously, providing a steady flow of fresh air into and out of the room. It does so by alternately switching between supply and extract modes approximately every 70 seconds.
  2. Heat Recovery: The unit is equipped with a high-efficiency ceramic heat exchanger. During the extract mode, it collects and retains heat from the air being extracted. This heat is then transferred to the incoming air during the supply mode, helping to maintain indoor temperatures and reduce heat loss.
  3. Reduced Indoor Air Pollutants: By continuously ventilating the room, the fan helps reduce indoor air pollutants and humidity levels, which can contribute to a healthier living environment and prevent issues like mold growth.
  4. Quiet Operation: The fan is designed to operate quietly, and it is described as ultra-quiet, making it suitable for use in bedrooms and other quiet areas.
  5. Neat and Discreet Design: The internal panel of the fan is designed to be discreet and unobtrusive, blending with the room's decor.
  6. Low Running Cost: The annual running cost of the fan is only £3.15 a year, emphasizing its energy efficiency.
  7. Limitations: This fan has some limitations though. It cannot be ducted more than a meter away and bends in the ducting are not recommended. Additionally, it is not suitable for use in wet areas such as bathrooms or kitchens.
  8. Room Size: TheHR fan is suitable for small to mid-sized bedrooms and living rooms with a cubic volume of up to 40m³. This corresponds to a room with a typical footprint of around 4.5 meters by 4 meters and a ceiling height of 2.2 meters.
  9. Recommendation for Larger Rooms: For larger rooms or spaces with a cubic volume of up to 70m³, their is a larger version which is recommended.
  10. Multiple Fan Installation: If you install multiple fans in one property, it is recommended to use a Controller to manage functions such as on/off, speed selection, and switching between extract and supply modes.

In summary, the heat recovery fan is designed for continuous and efficient ventilation in habitable areas of a home. It focuses on maintaining air quality, reducing humidity, and retaining heat while operating quietly and with low energy consumption. However, it has specific limitations and is not suitable for use in wet areas or larger rooms.

As you may have read on our website, condensation is fixed by VENTILATION! 

We not only supply and install PIVs for houses, but we can also install them in flats and basements too! These smaller units can sit flush to a wall and draw air from a vent which we can cut through an external wall. The unit then ventilates the whole flat or basement. By pushing filtered air around the property. This will push out the moisture and prevent mould from forming. We can also install a heated version which is slightly better in the colder months.

Moisture and Condensation problems?

Moisture and Condensation problems?

 

1. Understanding the Problem:

  • Humidity: This refers to the amount of water vapor in the air inside your home, which is higher in warmer conditions.
  • Condensation: When warm, moist air contacts cold surfaces like windows and walls, it condenses into liquid form, leading to condensation.
  • Damp: When condensation accumulates on surfaces over tim

 

1. Understanding the Problem:

  • Humidity: This refers to the amount of water vapor in the air inside your home, which is higher in warmer conditions.
  • Condensation: When warm, moist air contacts cold surfaces like windows and walls, it condenses into liquid form, leading to condensation.
  • Damp: When condensation accumulates on surfaces over time, it can result in visible damp patches in your home.

2. Curing High Humidity:

  • Reduce Water Vapor: Minimize activities that release moisture into the air, such as cooking, cleaning, and showering. Consider moving house plants outdoors and drying laundry outside.
  • Increase Ventilation: Ventilation allows moisture to escape. Use extractor fans, open windows, and ensure proper airflow in your home.
  • Dehumidifiers: Invest in a dehumidifier to extract excess moisture from the air.

3. Tackling Condensation and Damp:

  • Maintain Comfortable Temperature: Keeping your home at a minimum temperature of 18°C (not up and down from 15 to 22) helps prevent condensation by keeping the air and surfaces warmer.
  • Replace Windows: Older windows, especially those with single glazing, can contribute to condensation. Consider upgrading to more efficient double glazing or secondary glazing.
  • Protect Walls: Apply moisture-resistant coatings (ask for details)  to your walls to prevent condensation and damp issues. We supply and install products that can provide moisture resistance and added insulation.

It's crucial to address these issues promptly to maintain a healthy and structurally sound living environment. Regular maintenance and taking preventive measures can help reduce the risk of moisture-related problems in your home.
