Heat recovery ventilation may seem like a minor detail at first glance, but it proves to be essential for comfort, health, and long-term durability.
\n\nIn a small, airtight space such as a tiny house (but not only), inadequate ventilation<\/strong> means stale air, excessive humidity, mould growth, heat loss, and higher energy bills.<\/p>\n\n\n\n

In this article, we explain what heat recovery ventilation is<\/strong>, how it works<\/strong>, and why it is essential<\/strong> for an efficient and healthy tiny house.<\/p>\n\n\n\n

What Is Heat Recovery Ventilation?<\/h2><\/div>\n\n\n\n

A heat recovery ventilator (HRV)<\/strong> is a device that provides a controlled exchange of air<\/strong> between the indoors and outdoors, transferring thermal energy from the stale air being extracted to the fresh air being supplied.\n\nIn other words, a heat recovery ventilator continuously refreshes the air<\/strong> inside the home without significantly lowering the indoor temperature<\/strong>.<\/p>\n\n\n\n

A heat recovery ventilator works like the home\u2019s \u201cmechanical lung\u201d<\/strong>: it extracts stale, humid air from inside, brings in fresh air from outdoors, and uses the heat from the outgoing air to warm (or cool, in summer) the incoming air.<\/p>\n\n\n\n

How Does a Heat Recovery Ventilation System Work?<\/h2><\/div>\n\n\n\n

The system consists of two separate air circuits: one that extracts stale indoor air and another that supplies fresh air from outdoors.<\/p>\n\n\n\n

Between the two airflows is a heat exchanger<\/strong>, a component that transfers thermal energy without mixing the air, so only the stale air is removed \u2014 not the heat from the home.
\nThermal efficiency can reach up to 95%<\/strong>, which means minimal energy loss during ventilation.<\/p>\n\n\n\n
