In general ERVs are recommended for most residential and commercial applications, regardless if they are located in colder climates or warmer climates. The choice you make depends on if you want to transfer just heat like in exhaust from an indoor hot tube or pool room or heat & humidity, which is beneficial to optimize both comfort and energy savings in virtually any other application or climate zone.
The choice you make depends on if you want to transfer just heat or heat & humidity, the type of core in the unit, and other components of the unit. If you are deciding between an S&P HRV or ERV here is what we recommend:
Our HR Series Heat Recovery Ventilators are for residential use only. The HR Series utilize polypropylene cross-flow type heat recovery cores designed to transfer the heat between both exhaust & supply air streams without allowing any contamination or mixing of both air streams to maximize the efficient and improve indoor air quality.
Our TR Series Energy Recovery Ventilators are for residential or light commercial use and can be used in ALL climates. The exhaust and supply air streams are directed through a highly developed “air-to-air” energy exchange core. The air streams are physically separated by many layers of “plates” so there is no mixing or contamination of the fresh air. The plates are made of an engineered “resin” material that simultaneously transfers heat by conduction and humidity by attracting and moving water vapor from one air stream to the other. Unlike other ERVs on the market, no mechanical or electrical defrost system or drain pans are required! Since the TR does not require a defrost system or drain pan it can be installed in any orientation and in unconditioned spaces like attics and garages.
Our TRC Series Energy Recovery Ventilators are for commercial use and feature the same type of core as our TR Series so they too can be used in ALL climates.
