Did you know that the average person generates roughly one gallon of moisture indoors every day? Between showering, cooking, washing dishes, even just breathing, a lot of moisture can be trapped inside your home. This can be especially problematic in winter where excess moisture can lead to indoor window condensation build up, and over time, if left unmitigated, will cause window damage or other structural defects. Other side effects of excessive moisture are rust, mildew, and mold causing homeowners to experience associated unpleasant odors and potential health issues.
ERV or HRV?
Some manufacturers continually lecture that their Heat Recovery Ventilators (HRVs) should be used in the north and their Energy Recovery Ventilators (ERVs) in the south, using some self-published, authoritative-looking map. Unfortunately, in many cases, this has been promulgated to consumers and the building and HVAC industry as gospel for all brands and models. Yes, these companies have specific recommendations for their own models, using their own map to easily highlight areas of differentiation. And RenewAire agrees, for the models that each manufacturer produces, their geographical guidelines should always be followed. However, RenewAire produces ventilation systems that have no such geographical limitations and the broad assumption of HRVs in the north and ERVs in the south is not applicable. Our same product can be reliably used in Portland Oregon, Portland Maine, Denver Colorado, Phoenix Arizona, Minneapolis Minnesota, or Miami Florida, and all locations in between, year-round
RenewAire utilizes a technology in our energy exchange core that does not allow condensation (liquid water) to form. Without liquid water forming, there is no need for defrost mechanisms which limit needed ventilation during cold weather. Additionally, RenewAire's ERVs are effective at controlling excess winter humidity in tight houses because they don't recover all of the moisture from the exhaust air. The RenewAire energy exchange core is designed to recover less moisture than heat, so plenty of excess moisture is exhausted out of the house. And because cold weather air is very dry, the long-term effect is making the house drier. Excess winter humidity is one of the top problems people solve with RenewAire. Studies show that enthalpic-transfer (transfers both heat and humidity) air-to-air exchange ventilators like RenewAire, when operated at the ventilation rates recommended to control poor indoor air quality, have plenty of moisture-removal capability in cold climates.
The Natural Choice for Fresher Air
Contrary to other manufacturer’s claims, RenewAire ERVs are the best ventilation choice in any part of the U.S. They temper heat and humidity extremes of ventilation air year-round, in all climates. Additionally, RenewAire has produced ERVs for nearly 30 years, and while the majority of our products are installed successfully in the Northern Tier states, we have installations throughout North America. RenewAire’s correct application of our own products allows us to exceed the growth of the growing Energy Recovery market and also become a dominant player in that marketplace. So, feel free to call us to learn more. We will work with your heating professional to get one successfully installed into your home right away.
Please Refer to the Product Specific Installation and Operation Manual for Complete Instructions including Warnings and Precautions
Maintenance of the RenewAire Commercial Models (and Residential too!) is the simplest in the industry.
Filters and Energy Exchange Core
Inspect and change the filters regularly (generally every two or three months) and vacuum the face of the energy exchange core yearly when your ERV is in regular use. To access the filters, unlatch and remove or open the filter access door following the unit specific Installation and Operation Manual. Remove the filter keeper, if your unit has one, and pull the dirty filters out.
Dust collects only on the entering face of the energy exchange core, right where the filter sits. The interior of the energy exchange core remains clean even if the element faces are dust-covered. To clean the energy exchange core, simply vacuum the exposed faces of the energy exchange core with a soft brush attachment. While vacuuming, vacuum out any dust from the rest of the unit case. Finally, install new filters and reinstall the filter keeper if applicable.
Our Blowers Require no Lubrication. If necessary, vacuum clean the blower wheels at the same time you clean the face of the energy exchange core (annually).
The Energy Exchange Core is Not a Maintenance Item
Do not wash the energy exchange core or clean its faces using compressed air. It is not a maintenance item and is covered by a 10 year warranty with an expected service life well beyond that. RenewAire ERVs offer the lowest maintenance cost of any ERV, and are among the lowest priced to install. When you put all these benefits together, it's clear that RenewAire delivers greater performance value, comfort, fuel savings, safety, and ROI versus other rotary, heat pipe, and plate-exchanger manufacturers. This is just one reason why RenewAire is one of North America's leading manufacturers of ERV technology.
