Fresh air all year round.
OpenERV Energy Recovery Ventilators transfer clean air inside and move polluted air out, while retaining 91% of the heat energy. It is under development, for a few more months.
We are looking for beta testers, if you are interested, please email me at email@example.com .
Provides fresh air during hot or cold weather, without the addition or loss of heat to the dwelling.
Provides a reliable, regulated supply of fresh air. Never too much or not enough - better than an open window.
Is easy and inexpensive to retrofit into any area of any building, even buildings with no ventilation system, or electric heat. No ducting needed.
Features these core performance figures:
Ultra high real-world energy efficiency - 91% sensible, 45% average latent heat recovery.
High fresh air flow rate capability - 35 CFM net actual fresh air.
Absolutely whisper quiet - 0.2 Sone (~15 dBA).
Excellent long term maintainability, due to it's Open Source nature, and the use of standard components. No planned obsolescence.
Provides a return on financial investment >2x that of photovoltaic panels in many climates.
Doubles as an extra quiet, high pressure exhaust or supply fan, with ~90 CFM when the heat exchanger is removed.
Works with an optional True-Hepa filter adapter, using low cost, widely available, non-proprietary filters.
Designed and built to last for the very long term --> 25-50 years, for superior return on investment.
Can be configured to work with most home automation systems, including Google Assistant and Alexa.
Can be controlled with your phone.
Effectively reduces CO2 levels, reduces transmission of airborne pathogens and improves Indoor Air Quality in all metrics, but without heating or cooling related problems of a fan or open window.
Net total yearly cost of ownership and operation is much lower than conventionally made products, due to the long product design life and lack of planned obsolescence.
