What is Energy-efficient Ventilation System?

Energy-efficient ventilation, or a heat recovery ventilation 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 units 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 ventilation 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, habitable rooms, bathrooms and whole house, where noise levels need to be minimised!

The Prana Recuperator/ decentralised MVHR is an energy efficient, 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 different filters. 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 decentralised ventilation system with your smart home devices and automation systems, you can enjoy seamless management and monitoring capabilities

Energy efficiency

Decentralised mechanical ventilator 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 unit, there is a constant supply air (fresh and filtered), reducing stuffiness and maintaining a comfortable indoor environment. Additionally, the heat recovery unit 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.

Heat recovery unit offers 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! Contact us right now


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.

Reviews about Ecostream

Ecostream were absolutely amazing when I was looking to improve the air quality in my living room! Vyacheslav answered all my initial email questions promptly, and with lots of helpful information and advice. The pricing was also very reasonable. When it was time to install the Prana recuperator, the Ecostream team installed it in a compact spot, and did the installation quickly and very cleanly. Once installed, they were also very patient and helpful in advising how to use the recuperator properly. Since the installation, the Prana recuperator has been a huge help. We’re able to improve the air quality in our communal living space, without losing heat during these winter months. This has been extremely valuable for my household. I would strongly recommend Ecostream if you’re looking for better air quality in your home!

Slav at Ecostream is really hands on and gives excellent service both pre and post sale. The product eradicated the black mould problem I had in both my bedrooms during winter months so I would recommend the prana products

I genuinely believe that these are the best domestic ventilation systems out there. I started searching for the best solution when I found mould all over the wall behind my wardrobe. Since having the Prana fitted, its been an absolute game changer. No mould, no damp, no condensation. Just leave it on auto and let it work its magic! Slav and his team are top notch! 👌🏼

We moved into a house just over 3 years ago and for the first 2 winters experienced a lot of mould build up on the walls and ceilings. We would get pools of water each morning on the window sills and the windows would be covered in condensation. I had various trades people visit the property and suggest different ways of fixing the issue but they were all extremely expensive and none of them would guarantee it would resolve the issue. A builder recommended eco stream and I contacted them. I had some initial conversations with them regarding my issue and they talked me through the system and what it would do for me. After a site visit I agreed to have 6 units installed in each of the 4 bedrooms and 2 living areas. The installation went very smoothly and the installers explained everything they were doing at the different stages. They cleaned up after themselves and gave me a detailed demonstration of how to use the units. I have waited nearly a year to write this review because I wanted to see if they resolved the issues I had during the winter months when the mould previously would have been at its worst. After a full year I’m really happy to say that the units have solved the issues with mould and condensation fully. We now get no condensation on the windows in the morning even during very cold nights. No mould has appeared on the walls since the units were installed. We are extremely happy with the system and along with it solving our issues with mould and condensation they have also allowed us to keep a good circulation of fresh air through the property through the winter months without losing heat from the home. I recommend eco stream for any home or property that has condensation or mould issues.

I have used this company twice, installing a total of 4 of their Prana units in my London flat, to address a recurring damp problem. I found them to be courteous, professional and efficient. Moreover their products have made a material difference to the air quality and damp in the flat. I recommend them highly.

Its been a very positive experience working with Slav from Ecostream Ltd I have Installed 5 units of Prana in my New Build property and an additional 2 units in my Summer House. These units work exactly as I wanted them to and keeps the house fresh at all times without the overheads of losing heat from the house during the cold months. Slav has provided invaluable advise and was available throughout the long house building project. I am more that happy to recommend Ecostream Ltd for their professional services and the after sales service provided. The units themselves are fantastic and very advanced. I have left them running in Auto + mode and they do the rest of the job.

Fantastic product and great service from Slav at Ecostream. We purchased five units for a grade 2 listed cottage refurbishment as we wanted an airtight building but could not fit a full MVHR unit due to the restricted room for ducting. From the start to the finish Slav was attentive and very quick to respond. Once ordered the units turned up on site exactly when expected. There was a slight issue with one of the units (not Slav's fault) and when contacted Slav arrived the next day and sorted the issue. The product has been installed for a month now, the app is very easy to use and gives you loads of data both inside and outside the property. I cannot fault the product and the service from Slav has been second to none. Would recommend these units in any building to prevent the build up of condensation, stale air and mould.

I have had issues with ventilation in my 3 bed rental property and this was resulting in not opening the windows and or heating the dwelling sufficiently. I found Ecostream when doing my research on long term solutions to prevent poor air and resultant issues such as black mould, damage to interior items of the property. I am so pleased I found Ecostream. Slav came and gave an initial survey and was very honest, reliable and informative throughout the process. I ended up installing 4 units and after a mere week the difference in the air; no mouldy smell, etc was extraordinary. Slav were reliable from start to finish, I had air blocks which impacted the efficiency but Ecostream have now sealed these off and the units are really great. They look nice too! Very pleased with the service and products, highly recommend. My tenants are also pleased. If you are having issues with ventilation these units are the way to go and they are very low cost Great service by Ecostream would definitely recommend!

Ecostream gave us good advice and service. We bought three Prana units for our house and had them fitted by a local contractor (in Scotland). The units are excellent and provide good fresh air without losing heat from the house. And they are not audible on the lower settings, which is ideal for the one in the bedroom. Very happy.

We built a granny annex with lots of large windows at the bottom of our garden. During the winter months it suffered with condensation especially around all the aluminium windows and adjacent walls leaving puddles at the bottom of window frames. We pursued and researched many different companies and solutions until we came across Ecostream Prana system. To us this appeared to be the perfect solution and least invasive and so it was. From the very first contact with Slav, his recognition and knowledge of our problem gave us confidence that we had made the right choice and we installed two recuperators. And so one winter in and another looming we have no regrets. Problem solved 95%, the 5% missing is due to the badly installed window frames. No need to open windows, the air is always fresh. Fitted without fuss or disruption, clean and efficient. Thank you Slav!
