Heat Recovery Units

Please review our product comparison chart, and keep in mind that our products are most effective in the space or room where they are installed. Nevertheless, you can reach out to us with the details of the application (e.g., room or office), number of bedrooms, floor area, and ceiling height for recommendations on the most appropriate product for your space.

Please install our products in this manner:

Option 1: You may install one unit of MINI or MINT in the space where you will spend most of your time inside the tiny house. It is also recommended to install at least one unit of VENTPETIT in the washroom (bathroom or toilet room).

Option 2: If suitable, you may install one unit of CLIMATE to ventilate a tiny house without the need for a separate bathroom fan.

Please also review our product comparison chart.

The product has been deployed in diverse climatic zones which includes polar, continental, temperate, and desert regions.

The product can be mounted either horizontally or vertically, and the specific instructions are provided in the User Manual.

No. The product is built to operate independently of any external appliances.

We hypothesize that the accumulation of moisture is mitigated in our products due to the peculiar characteristics and operating flow rate of the air exchangers. Moisture accumulation has neither been observed nor reported to us, which implies that the moisture in the air stream in an indoor space would be exhausted to the outdoors.

Yes. The direction of heat transfer will automatically change such that thermal energy will flow from the hotter air stream (outdoors) to the colder air stream (indoors).

Internally, the MINI and CLIMATE units run on 12V DC and 5V / 12V DC, respectively.

Nevertheless, the units can be plugged into an AC outlet through the use of an appropriate intermediary AC – DC adapter. The DC end of the adapter can be connected to the unit whereas the AC end can be plugged into the AC power supply in a building. Additionally, the power sources for our products are certified to meet jurisdictional requirements by nationally recognized testing laboratories and the appropriate insignia is displayed on relevant website pages.

For off-grid applications, a 5.5 mm male plug connector can be used to directly power MINI from a source that supplies constant 12V DC. Likewise, CLIMATE can be powered by a source that supplies constant 5V DC and up to 12V DC for maximum air flow rate.
