Heat Recovery Ventilators

Heat Recovery Ventilators keep outgoing stale air separate from incoming fresh air and completely rejuvenates the air throughout your entire home up to eight times a day. The Field Controls Heat Recovery Ventilation systems features a patented aluminum core which efficiently transfers heat from outgoing stale air to incoming fresh air. Our Heat Recovery Ventilators let you enjoy an energy efficient home without breathing harmful indoor fumes from paint, plastics, carpets, adhesives, and household products, or lingering pet odors or moisture that causes mold.

HRV systems are recommended for colder climates. The Heat Recovery Ventilation system is ideal for colder, northern climates. The Energy Recovery Ventilation system is designed for the hot, humid southern climates. Either system can be used in the southwest and California, depending on local conditions.

The Polypropylene Heat Recovery Ventilation Core is designed to maximize airflow and performance. The core is constructed from a composite of polypropylene materials that allows latent heat transfer from one airstream to another while preventing cross-contamination. The ERV Enthalpy Core advanced heat and humidity exchanger is superior to existing paper based cores, and is manufactured from a durable polymer membrane that enables energy recovery systems to increase their total efficiency, operate in extreme climates, and ensure the cleanest air possible.

What’s the Difference?

What is the difference between HRVs and an ERVs? HRVs and ERVs are similar systems in that both supply air to the home and exhaust stale air while recovering energy from the exhaust air in the process. The primary difference between the two is that HRVs transfers heat while ERVs transfers both heat and moisture.

How it Works

The fans of an HRV will pull fresh air into a home while simultaneously exhausting stale air from the home. In most installations, the fresh air is delivered to the living room and bedrooms while the stale air is removed from the bathrooms, laundry rooms, and sometimes the kitchen.

Both the fresh air stream and the stale air stream flow through the HRV. The System Core allows some if the heat from the warmer air stream (the stale air in winter, the fresh air in summer) to be transferred to the cooler air stream. In winter, the system “recovers” some of the heat that would have otherwise been exhausted. This heat transfer occurs without any mixing of the two air streams.
