Heat Recovery Units (MVHR)

Heat Recovery Unit and Air Recovery: The Key to a Healthy and Energy-Efficient Home

In today's world, where we spend a great deal of time indoors, the quality of the air we breathe has become more important than ever. Airtight construction of new and renovated buildings delivers excellent energy efficiency, but at the same time prevents the natural exchange of air. The result is increased humidity, stale air, the build-up of harmful substances and ideal conditions for mould to develop. The solution? Air heat recovery using a device known as a heat recovery unit (MVHR).

At the Akvavent.si online store, we offer comprehensive ventilation solutions, with the air heat recovery unit at the heart of our range. We know that choosing the right system is crucial, which is why we have prepared a guide to help you understand why heat recovery is the best investment in your health and comfort.

What Is a Heat Recovery Unit and How Does Heat Recovery Work?

Many people ask: "What is a heat recovery unit?" and "What is heat recovery?". Put simply, a heat recovery unit (MVHR) is the heart of a ventilation system, enabling the controlled exchange of air between the inside and outside of a building. Its main task is to supply fresh outdoor air to the room while extracting stale, humid and CO2-saturated air outside.

How does a heat recovery unit work?

The magic of heat recovery lies in the built-in heat exchanger. The heat recovery unit ensures that heat from the stale indoor air (e.g. 22°C) is transferred to the fresh but cold outdoor air (e.g. 0°C) entering the room. Through this process, known as heat recovery, the incoming air is pre-heated to a pleasant temperature (e.g. 19-20°C) with minimal energy consumption.

Heat recovery ventilation in winter and summer

In winter this means you reduce heat losses by more than 90%, while in summer the system works in reverse. Hot outdoor air is cooled on entry by the cooler exhaust air you extract from the room, helping to keep the interior pleasantly cool and reducing the need for air conditioning. Heat recovery ventilation thus ensures a constant supply of fresh air without needlessly wasting energy.

The Main Benefits of Air Heat Recovery for Your Home

Investing in heat recovery ventilation brings numerous benefits that you will feel every day.

• Constantly fresh air for better wellbeing: It ensures the continuous circulation and supply of fresh air, which has been proven to improve wellbeing, concentration and sleep quality.

• Major energy savings: By recovering heat from the exhaust air, it drastically reduces heating and cooling costs. Energy recovery is key to achieving high energy efficiency in your home.

• Effective prevention of damp and mould: By regularly extracting humid air, it effectively prevents the formation of condensation and mould, which are harmful to human health and cause damage to the building structure.

• Air filtration for healthy breathing: Modern heat recovery units are equipped with dedicated filters. A quality heat recovery unit filter successfully removes dust, pollen, allergens and other impurities from the air, which is beneficial for allergy sufferers.

• Less noise and draughts in your home: As there is no longer any need to constantly open windows for ventilation, the intrusion of disturbing outside noise is reduced and you avoid unpleasant draughts.

Decentralised Heat Recovery Unit: A Flexible Solution for Every Room

When a comprehensive centralised system is not possible or necessary, a decentralised heat recovery unit is the ideal choice. These are individual units installed directly through the external wall of the room you wish to ventilate. Decentralised heat recovery is the perfect solution for renovations, apartments in multi-dwelling buildings and for targeted problem-solving in individual rooms such as bedrooms, children's rooms or living rooms.

Decentralised Heat Recovery Unit with Installation: A Fast and Efficient Path to Fresh Air

One of the biggest advantages of a decentralised heat recovery unit is its easy installation. At Akvavent.si we understand that customers often opt for turnkey solutions, which is why the query "decentralised heat recovery unit with installation" is among the most common.

Installation of an Ø100 mm heat recovery unit

Installation of a heat recovery unit is quick and minimally invasive. It requires only a wall penetration, most often with a diameter of Ø100 mm or 100 mm, which is now the standard for most decentralised units. Such installation does not require complex duct runs throughout the building, which means fewer interventions in the space and a faster path to high-quality living.

Decentralised Heat Recovery Unit for the Bathroom: Stop Damp and Mould

The bathroom is the room with the highest concentration of humidity, so effective ventilation is essential. Conventional bathroom extractor fans only remove the air, and with it valuable heat.

Heat recovery fan for damp rooms

A decentralised heat recovery unit for the bathroom or bathroom heat recovery unit works as an advanced heat recovery fan. This device is not just a fan; it is a smart system that simultaneously extracts moisture-laden air and supplies fresh, pre-heated air back into the room. This not only prevents the formation of mould and unpleasant odours, but also maintains a pleasant temperature in the bathroom and saves energy.

Decentralised Heat Recovery Unit Price: Quality and Affordability

Price is often the deciding factor. The price of a decentralised heat recovery unit is significantly more affordable than investing in a centralised system, making it accessible to a wider range of users.

What is the price of an air heat recovery unit?

Our range includes a wide variety of models. The price of an air heat recovery unit varies depending on capacity, efficiency and additional features. At Akvavent.si we offer both affordable, reliable models and more advanced devices such as the WiFi heat recovery unit, which can be conveniently controlled via an app on your smartphone.

Does the cost of heat recovery pay off?

Yes. Although it represents an initial investment, the cost of heat recovery pays for itself over time through significant savings on heating costs. When comparing the price of decentralised heat recovery, it is important to consider the long-term benefits for your wallet and your health.
