How PRANA decentralised MVHR helps reduce heating bills

This winter promises to be extremely difficult, with the heating season posing a real challenge for the British energy system.

Will there be enough resources to heat our homes, schools, and nurseries? How much will precious heat cost for business owners? How should we go about saving energy costs? These are the questions of utmost concern today, not only for figures in authority but for every resident of our country.

British people often resort to standard heat-sealing methods in order to retain some warmth at home while saving on heating bills. They insulate apartments, offices, shops, and other private and commercial objects.

Common heat-sealing methods are:
• insulation of the facade of the house
• insulation of the roof and walls
• installation of hermetic plastic double-glazed windows
• insulation of basement premises
• installation of an individual heating unit

While methods such has these can reduce the loss of precious heat and increase the overall energy efficiency of the house, they can also cause a number of serious problems related to the disruption of natural ventilation in the property.
Insulated apartments, private houses, and offices turn into a kind of thermos, plagued by high humidity, a constant lack of fresh air, and dangerously high carbon dioxide content.
If a room is not properly ventilated, over time the windows begin to sweat, and excess moisture, mould, fungus, and persistent unpleasant odours appear. Interior furnishings may deteriorate, and microorganisms and bacteria that are harmful to the human body multiply.


“But can’t I just open a window?” you might ask. Doing so will restore natural ventilation, but it also causes the room to lose precious heat, driving you to return to expensive heating methods. In other words, the whole reason for using heat-sealing methods in the first place is negated, as you’re left with a cold room and high energy bills.

Opening the window can increase the heating costs of the building by at least 30%, while in the hot season, with the need for an air-conditioner in the room, this figure rises to a 70% overspend of electricity for additional air-conditioning. You shouldn’t have to choose between this and a house riddled with mould and condensation.

There is a solution that will keep you warm, healthy, and help you save money on heating bills. Specialists in the field of ventilation advise using energy-efficient technologies that help increase the building’s energy efficiency class while also ensuring effective ventilation. Such innovations have long been very popular in many countries around the world and have proven their high efficiency.

Advantages of the PRANA recuperator/ decentralised MVHR

One such solution for increasing energy efficiency and ensuring natural ventilation of a premises is the PRANA recuperator. Numerous tests and thousands of implemented PRANA projects in different parts of the world, from arid Spain, Italy, Italy, Germany and Poland to rainy Great Britain, Sweden, and Norway, have proven the efficiency of Ukrainian-manufactured PRANA’s smart ventilation technology.

PRANA recuperators/ dMVHR retain up to 96% of the heat within a property through energy-efficient methods. A highly efficient copper heat exchanger inside the recuperator allows the heat (or coolness) of exhaust air, as it is extracted from the room, to be transferred to the fresh outside air that is being brought into the room. The exhaust and inflow air does not mix, but the streams flow simultaneously through separate chambers in the device. Therefore, fresh, oxygen-rich air that has already been heated or cooled to a comfortable temperature by the device, enters the room.

In addition to huge savings on energy bills, installing the Prana ventilation system will provide you with several additional benefits:
• convenient control options via a remote control and app
• a stable, comfortable temperature throughout your property
• CO2eq and VOC levels monitored and controlled
• a choice of automatic operating modes
• protection against allergens (such as pollen) when installed with a filter
• efficient operation 24/7.

As well as being a highly efficient thermal conductor, the copper heat exchanger, made from natural antimicrobial metal, has additional health advantages. The risk of bacteria and viruses multiplying on copper surface is drastically reduced. A 2022 research project led by scientists at the University of Southampton (Great Britain) revealed that copper surfaces rapidly inhibit the spread of COVID-19 and other. With this in mind, you can rest assured that the PRANA recuperator/ decentralised MVHR will supply your premises with only the freshest of air.

Progressive technology for fresh air around the clock
Thanks to the device’ Wi-Fi connectivity and numerous additional functions, PRANA ventilation systems are convenient, safe, and easy to use and control from any location. The PRANA app allows you to monitor and adjust the air quality in your premises at any time.
That is why, by installing the recuperator/ dMVHR, you will say goodbye to all the problems associated with poor ventilation. You can bask in the certainty of having high-quality clean air, heated in winter and cooled in summer, all year round. Whilst saving you from the immediate costs of heating your property, this eco-friendly option also enables you to avoid future expenditures relating to condensation, mould and dampness issues.

Easy, fast, and discreet installation!
The Prana recuperator is a fairly compact device, so its installation is simple and speedy. Household series models can be installed in up to two hours without disturbing the structure of the room. The process consists of the following stages:
• selection of the installation area
• drilling a hole
• installation of recuperator
• connection to the power grid.

For the correct operation of the device, PRANA household models are mounted on an wall bordering the outside. The recuperator is installed in the upper part of the wall, at a distance of 100–150 mm from the ceiling, the adjacent wall, and other obstacles.
The selection of an installation location is also affected by the presence of an air conditioner. For efficient operation of the device, the recuperator should be placed on another wall, above the air conditioner, or on the side, at a distance of at least 300 mm.

Connection to the power grid
The PRANA power supply is connected to the network, with a standard voltage of 230 volts and a frequency of 50 Hz. This can be completed in one of two ways: by plugging it into an outlet or directly connecting it to the house’s electrical network. In the first case, you need an outlet sufficiently near to the recuperator. In the second, a cable is brought to the location of the device one the network has been de-energized. That is why the connection should be made by a professional electrician.

Calculation of recuperator payback
And finally, we will consider the calculation of the payback of ventilation with PRANA recuperators for the playing-dining room of a nursery with a volume of 154.6 m3.
The multiplicity of air exchange in such premises, according to DBN B.2.2-4:2018 (Preschool education institutions: Buildings and structures) is 1.5 times.
The provided calculations are part of real ventilation projects implemented by European educational institutions. However, depending on the characteristics of the building, the heating system, the outside air temperature, and other factors, the results of the calculations may differ.*

During this time, PRANA will provide an influx of fresh air at a stable temperature without the need for additional mechanical ventilation or heating. This will significantly increase energy efficiency indicators and allow you to save money.
In addition, the full payback period of the ventilation system for the playing-dining room of the kindergarten will be 15-22 months.
