Heat recovery ventilators (HRV) constantly supply fresh air to provide a healthy indoor environment by reducing odors and and indoor pollutants, such as radon, formaldehyde, tobacco smoke, nitrogen dioxides, carbon monoxide, and pesticides. Energy recovery units constantly bring fresh air into the home while exhausting like amounts of stale indoor air at the same time.

The recovery part of the ventilation means that the hot or cold energy in the air (depending on the season) is extracted from the indoor air before it is exhausted and transferred to the incoming air, so that there is little energy lost.

Heat Recovery Ventilators use separate blowers to constantly supply  incoming fresh air while exhausting outgoing stale air. The heat-exchange core transfers heat to fresh air without mixing the airstreams. The damper automatically stops cold air for defrosting.

The efficiency of heat recovery ventilation became a necessity due to increasing heating costs. Before the '70s, we happily cranked up the thermostat when the house felt chilly. Once heating costs went through the roof, though, we all put on sweaters and started looking for ways to save. With up to 40 percent of our heating dollar going to air drafts, sealing homes began to seem like the best defense against high heating bills.

Unfortunately, those heat-sealing upgrades -- tight windows and doors, insulation and vapor-barrier improvements, modern siding and caulk for every crack through which air might pass -- while making the home thermally efficient, sealed in a plethora of toxins, creating what's often referred to as "sick building syndrome."

It turns out that those heat-robbing drafts played an important role in the ecosystem of the home: they provided fresh air to breathe. Thus the birth of home ventilation air exchangers.

HRV vs ERV

Heat recovery ventilators (HRV) will transfer temperature only from the high temperature air to the low temperature air. Energy recovery ventilators (ERV) transfer both temperature and moisture. Since transferring both temperature and moisture has benefits in both winter and summer, ERV's are a better choice in all but the most northern colder climates for providing year round fresh air to the home.

Heat recovery units can be installed in an existing home, as well as a new home, and are an integral part of the heating and air conditioning system. HRV systems can work with any forced air system equipped with a blower and duct system. It can also be used with non-forced air systems (floor heat coils, for instance) as an independent system.

To maximize the air quality, you can keep your home closed year-round and operate the HRV system constantly, efficiently producing a fresh and secure environment.

Heat recovery ventilators should be serviced about every six months. The simple procedures are fully described in the manual provided with each unit. These maintenance procedures can be completed by you or your contractor, if you desire.

How to Determine the Right Venmar Model

All Venmar models are rated by the Airflow rate. To calculate your airflow rate, count every room in your house, including bathrooms and service porches, and give each room 10 points, then add 10 points to the total. For instance, if you have 3 bedrooms, 2 bathrooms, a dining room, kitchen, living room, den and service porch, you have 10 rooms. That's 100 points. Add 10 extra to get 110. That means the upper CFM range must be at least 110. Looking at the HRV model options below, you choices would be a Constructo 1.5, Solo 1.5 or HE 1.3.

If you have high ceilings or larger than standard rooms, increase the CFM by 10 to 30 points, depending on how much more cubic air volume is in the house. (If you have an existing HVAC system, you can also find out its CFM rating and use that figure.)

Get the Ultimate in Clean Air for Your Home

Combine an Air Oasis Induct Air Purifier with a Venmar Ventilation System (or any HVAC system) and get the ultimate in pure air in your home.

The Venmar Air Exchange System is fabulous for recovering heat or energy, providing fresh air, controlling humidity and removing particulate (dust, pollen, dander, etc.), but by adding the powerful broad-spectrum pollution purification abilities of an Air Oasis HVAC Induct Air Purifier, you get the ultimate in whole-house clean air. Air Oasis air purifiers destroy bacteria, viruses, pesticides, herbicides, mold spores, chemical fumes and gases, VOCs, odors and more.

The residential and business HVAC (heating, ventilation and air conditioning) induct model is designed for use with forced-air heating and central air conditioning systems (HVAC) to purify the air in all rooms served by ductwork in small to large single-family homes and office buildings. Turn your central heating and cooling system into an air-cleaning machine to significantly reduce pollutants and contaminants in your entire home or business. For more information, see the Air Oasis Air Purifiers.
