What is Energy-efficient Ventilation?

Energy-efficient Ventilation, or a heat recovery system (HVAC) is an innovative technology that not only helps to reduce energy consumption, but also promotes a healthier and more comfortable indoor environment.

A heat recovery ventilation operates on a simple yet ingenious principle: it utilises the temperature difference between outgoing stale air and incoming fresh air.

Proper ventilation with heat recovery unit is crucial for maintaining a healthy indoor environment. Heat recovery systems ensure a continuous supply of fresh air is provided to your property, while also filtering out impurities and pollutants.

This helps to improve indoor air quality, reducing the risk of respiratory issues and creating a more comfortable living or working space.

Modern heat recovery systems with a cooper heat exchanger are designed with noise reduction in mind. The units are equipped with insulated enclosures and advanced fan technologies, ensuring that they operate quietly. This makes them suitable for various settings, including bedrooms, living rooms, bathrooms and offices, where noise levels need to be minimised!

The Prana Recuperator/ decentralised MVHR is a quick-to-assemble, smartphone-controlled ( Bluetooth, wi-fi) ventilation system that can solve all of your problems! It utilises an innovative system of CO2, humidity, air quality VOC, temperatures sensors to monitor, correct and control the air quality, CO2, humidity and temperature in any indoor environment with G2 filter. It’s similar to autopilot. With a two-year warranty and ten-years lifespan, the Prana Recuperator/ dMVHR has your future covered.

Our advantages

Improved indoor air quality

MVHR systems continuously exchange stale indoor air with fresh outdoor air. They filter out pollutants, allergens, and odours, promoting better indoor air quality. This is particularly important in urban areas or locations with poor outdoor air quality.

Smart home integration

Our ventilation system can be fully integrated with Amazon Alexa and Google Assistant. By integrating your ventilation system with your smart home devices and automation systems, you can enjoy seamless management and monitoring capabilities

Energy efficiency

Decentralised mechanical ventilation with heat recovery recover heat from the exhaust air before it is expelled outdoors and use it to preheat the incoming fresh air. This heat recovery process significantly reduces the energy required to heat the incoming air, leading to energy savings and lower heating bills. Comfortable air temperature guaranteed.

Enhanced thermal comfort

With the heat recovery ventilation system, there is a constant supply air (fresh and filtered), reducing stuffiness and maintaining a comfortable indoor environment. Additionally, the heat recovery system helps maintain a consistent temperature throughout the building.

Reduced condensation and mould growth

Unlike natural ventilation, the heat recovery ventilation systems control humidity levels by extracting moist air from the wet rooms like kitchens and bathrooms and replacing it with fresh, drier air. By managing moisture effectively, these systems help minimize condensation and prevent the growth of mould and mildew.

Noise reduction

Decentralised MVHR units are designed to operate quietly. They typically have noise-reducing features, such as insulated casings and low-noise fans.

Improve Your House with a Heat Recovery Ventilation

Heat recovery systems offer a multitude of benefits for homeowners, ranging from improved energy efficiency and enhanced indoor air quality to consistent temperature control, noise reduction, financial savings, and positive environmental impact – overall, these amount to a better quality of life!

Heat recovery systems are designed to recover and reuse the heat that is typically lost during ventilation or air extraction processes. By capturing and redistributing this wasted heat, these systems significantly improve energy efficiency in your home. This means that you can reduce your reliance on traditional heating and cooling methods, resulting in substantial energy savings and lower utility bills.

By installing a heat recovery system in your home, you can optimise your living space while contributing to a more sustainable future!


Heat recovery is an option used in domestic dwellings, which helps to reduce the heating and cooling demands of buildings.

Heat recovery systems are a technology that capture and reuse excess heat in the air, or heat generated by various industrial processes or HVAC (heating, ventilation, and air conditioning) systems. They help to reduce energy consumption and improve overall efficiency by recovering and transferring this heat to other areas or processes.

If the term “MVHR”, or Mechanical Ventilation with Heat Recovery, “dMVHR”, or decentralised Mechanical Ventilation with Heat Recovery sounds complicated, don’t worry! It’s actually a straightforward process that can be broken down into three simple steps:

  1. Stale air is extracted from the room while fresh air is drawn into it by the ventilation unit. This creates a continuous airflow.
  2. The heat recovery ventilation unit (HRV system), MVHR, decentralised MVHR recovers the heat from the extracted stale air and transfers it to the incoming fresh air.
  3. The clean, temperature-regulated air is distributed throughout the property.

Using an environmentally-friendly heat recovery ventilation system offers several advantages, including reduced energy costs. By reusing exhaust heat, your overall energy consumption can be significantly reduced. Heat recovery systems also help to lower greenhouse gas emissions and decrease the carbon footprint of industries and buildings.

Heat recovery systems can be used in a broad variety of sectors, including industrial or commercial buildings and residential settings; they can be implemented in manufacturing plants, hospitals, data centers, hotels, swimming pools, and more. Essentially, any process that generates surplus heat can potentially benefit from a heat recovery system.

Yes, heat recovery systems can often be retrofitted into existing buildings, even if they already have their own ventilation system fitted, provided there is sufficient space and compatibility. However, the feasibility and cost-effectiveness of retrofitting may vary depending on the specific situation and the complexity of integration.

We always recommend you consult with a qualified professional or an energy engineer to assess the suitability and design of a heat recovery system for your specific needs.

Regular maintenance is an important way to safeguard the optimal performance and longevity of a heat recovery system. This typically includes cleaning or replacing filters, inspecting heat exchangers for any grime or corrosion, checking fans and motors, and making sure that nothing is obstructing airflow.

We recommended that you follow the manufacturer’s guidelines and consult with a qualified technician or service provider for routine maintenance.

Slav and his team at Ecostream are consummate professionals. Communication with them by email, phone and WhatsApp is a dream. Ontime installation of 8 units, on 4 floors, was completed without fuss and ontime, with both installers working ceaselessly and tidily throughout the day. In addition, Slav's technical knowledge and instruction on how to use the phone App and manual remote to control the system is second to none. I highly recommend these guys as honest, hard working installers of a cutting edge, world class ventilation and heat recovery system of the future.

We had an Ecostream fitted to our rental property in Bethnal Green E2 . The ongoing mould problem was finally eradicated. Happy tenants , happy landlord . We also had the same model fitted in our flat in E18 South Woodford . again the problem has now been. Resolved . Great service , the guys are professional, polite and very clean workers . We were introduced to eco stream from a friend of ours who had about 3 systems installed in his rental properties.. Anthony Gladwell

I have had an excellent experience with hiring Ecostream for the installation of the Prana ventilation systems. Communication has been quick & easy, I felt valued from the beginning and huge efforts were made to come and view the property for a quote & for the installation. Being based in the South West, it was a long journey for them for both visits, and at no point did I feel like it was an inconvenience for them. On the day of installation, the work was seamless and I was kept informed about their progress. They were respectful of my property and were very mindful about mess/potential dust. They explained clearly how to use the systems, and how to maintain them (cleaning etc.). They also contacted me after a week to ensure there had been no issues arise since. I’ve definitely noticed a difference in my flat since the installation. I live in a basement flat so mould & high humidity has been a huge problem. This has definitely helped to tackle these issues & prevent the reoccurrence of the mould.

We have just completed our new self build. A single storey, oak frame, barn style home with high vaulted ceilings. Because the structure is so well insulated and air tight we needed an MVRH system to ventilate the property. However, because we are single storey will no loft space for ducting we were unable to install a traditional system and needed to find a decentralised option. We did a lot of research and found that the Prana system was exactly what we needed. Before it was installed our building was dripping in condensation due to the cold weather earlier this year, the fact our structure is so air tight and the fact the plastering had just been completed. Within days of the Prana system being installed the humidity levels had dropped from 90%+ to 60% and under. We have now been living in the property for the past 4 months and the Prana units provide a fresh balanced air quality with a low energy running cost. We highly recommend the Prana system and Slav and his team were highly professional and easy to communicate with throughout the entire process.

We’ve installed one in our new eco-extension and would highly recommend. It is quiet, works well in automatic mode and the service from the company is absolutely excellent. It’s a really high quality and well engineered product. We also have some basic Ventaxia continuous flow MVHRs which are absolutely bare-minimum basic - noisy, cheap and nasty plastic - the Prana is in a different class.

What a fantastic product and service!! We needed to bring in additional fresh air into parts of a facility that did not have the space for ducting. The Installation of 30 decentralised MVHR systems Prana 210C ERP PRO - Did the trick !! The units work along side our existing internal AC Units to provide plenty of clean fresh air significantly improving the Air Quality in the area. Plus with the heat exchange it means we are able to maintain the temperatures required. The fitting was carried out in a safe and efficient manner and the after care and servicing has also been excellent.
