Enjoy Fresh and Clean Air with Prana recuperator

The Prana Recuperator/ decentralised MVHR employs state-of-the-art technology to minimise its impact on both your energy expenses and the environment. These innovative ventilation units not only replenish the air you breathe, but also have the ability to heat or cool your property.

Remarkably, they consume as little as 3 watts and a maximum of 30 watts per hour — less than the energy consumption of an average domestic lightbulb!

Operating within a copper heat exchanger, the warm exhaust air efficiently transfers its heat to the cold, fresh air being supplied to the room.

This transfer occurs in separate chambers within the copper core, ensuring that the inflow and exhaust air streams remain distinct and do not mix.

Consequently, heat recovery takes place with an impressive efficiency rate of up to 96%. Even during the summer, the inflow air is pleasantly cooled through this same mechanism, requiring minimal energy expenditure. Also, it maintains natural ionic air composition.

The Benefits of Heat Recovery Ventilation

The Prana Systems continuously exchange stale indoor air with fresh outdoor air while filtering out pollutants, allergens, and odours. They help to maintain a healthier and cleaner indoor environment by reducing the buildup of indoor air contaminants.

Prana ventilation systems are also designed to recover and transfer heat from the outgoing stale air to the incoming fresh air. This heat exchange process helps pre-condition the incoming air, reducing the need for additional heating or cooling. As a result, energy consumption for heating and cooling is significantly reduced, leading to energy cost savings and a reduced carbon footprint.

Prana systems can even help control moisture levels in indoor environments. They help remove excess humidity from the air, reducing the risk of mould and mildew growth in your property.

How do the Prana Ventilation Systems Work?

Ventilation with heat recovery is an advanced mechanical system, designed to minimise heat loss while effectively ventilating a room.

These systems are commonly referred to as MVHR, decentralised MVHR (Mechanical Ventilation with Heat Recovery) units, and you may also come across the term HRV (Heat Recovery Ventilation), which essentially refers to the same thing. MVHR units operate by extracting stale air from within the building and passing it through filters. At the same time, they capture the thermal energy from the extracted air instead of releasing it outside, and transfer it to the filtered incoming air.

The key components of MVHR units include a heat recovery cell responsible for extracting indoor heat and supplying it to the fresh air entering the building, fans that draw in and expel air, and filters that effectively remove dust and particles from the outside air.

Moreover, Prana Recuperators and air conditioning systems are equipped with a summer bypass feature, enabling users to regulate the amount of thermal energy recovered if a cooler environment is preferred. It is easy to change speeds, select operating modes and monitor air quality indicators in your room. Get in touch with Prana online to find the perfect ventilation solution for your home. We are able to carry out ventilation projects of any complexity for you.

Read about Prana ventilation


The recuperator is designed as a finned tubes heat exchanger in order to improve the heat transfer coefficient on the tube external side where vapor flows. The Prana ventilation system works by extracting exhaust heat from inside the building and passing it through a heat exchanger. This heat exchanger transfers the heat from the outgoing air to the incoming fresh cold air, ensuring minimal heat loss. Also it has an air quality indicators. The filtered and preheated fresh air is then circulated back into the building, creating a healthier and more comfortable indoor environment.

The Prana Recuperator comes with user-friendly controls that allow you to adjust the ventilation settings according to your preferences. The device may include features such as airflow adjustment, humidity control, and programmable timers for convenience and customisation.

Yes, The Prana Recuperator is designed to be versatile and can be installed in various types of buildings, including residential homes, offices, schools, and other commercial spaces. Also Prana Recuperator is a significant economy on installation and energy resources.

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!
