Indian summer, warm September and the anticipation of a golden autumn are a good time to complete preparations for the long winter season. The most important thing in winter is to keep your home warm. We’ll tell you how to take care of your home’s energy efficiency during the cold months right now.

What should you do to keep your home warm?

To improve energy efficiency, the following methods of keeping your home warm are used:

• insulation of the roof and walls;
• installing sealed windows;
• use of efficient heating appliances.

These measures will help keep the heat inside the house. However, along with the warm air, homeowners are also exposed to the so-called «thermos effect». Exhaust air with a high content of moisture, carbon dioxide and other substances hazardous to health will remain in the room. Yes, it will be warm at home, but you get additional problems along with it.

Over time, the humidity level rises to critical levels, fungus and mould appear, and condensation appears on the windows. The first desire that arises in such an environment is to open the windows and ventilate the rooms well. And at this point, all efforts to keep the heat in go to waste. After all, during the cold season, more than 30% of heat is lost through windows.

An effective solution to the problem is to install an air recuperator.

How does an air recuperator help to keep you warm?

Modern homes require ventilation without opening windows, heat loss and drafts. The essence of heat recovery with the Prana recuperator is the transfer of heat from the exhaust air to the supply air. That is, instead of removing hot air to the street, we transfer its heat to the incoming cold air. At the same time, the air flows are not mixed. We get warm, fresh, clean air and an optimal microclimate at home at the same time.

PRANA recuperators meet all the requirements:

• heat exchanger made of German copper (thermal conductivity is 2 times higher than aluminium);
• air quality sensors;
• automatic control;
• Ukrainian and European hygiene certificates;
• power consumption from 4 Watt-hours;
• Efficiency up to 98%.

Maintaining a stable indoor temperature provides a comfortable environment for living and working. Reduced energy consumption reduces heating and air conditioning costs.

Heat saving with the PRANA recuperator: efficiency analysis

The effectiveness of recuperators in the winter season is best demonstrated by the results of thermal imaging. The photo shows a PRANA-150 recuperator installed on the basement of a house. The survey was carried out during the period of repair work (in winter) with a FLIR thermal imager based on Cat.

• Indoor temperature: +15℃;
• Outdoor temperature: +5℃;
• Wall temperature: +10℃;
• Recuperator cover temperature +12℃.

As we can see, even in an insufficiently warm basement room at the stage of repair, the PRANA-150 recuperator does its job. The supply air temperature rises when the room temperature rises (optimally to 18-22℃), which provides comfortable conditions for people. For additional energy savings, the basement of the house should be waterproofed and insulated, as this area is especially prone to freezing in the cold season.
