Eleven Reasons We Love Zehnder HRV and ERV Systems

Woman Kissing Zehnder Q HRV Unit

You’re more likely to want to smooch your zehnder system after it’s installed, but even before, there’s plenty to love!

This January marked the eleventh year Small Planet Supply has been selling Zehnder HRV and ERV systems in the western USA and Canada.  Since then, we’ve sold thousands of systems to homeowners and multi-family builders.  In honor of our eleven years of selling these amazing Zehnder systems here’s eleven reasons why we love Zehnder HRV and ERV systems and why they are a good choice for your home or project:

1.    Zehnder’s High Efficiency Ratings

Zehnder units boast some of the highest efficiency ratings in the industry, minimizing energy consumption while maintaining optimal ventilation. This translates to cost savings on your energy bills.

2.    Zehnder’s Excellent Heat Recovery

Zehnder's counterflow heat exchangers efficiently transfer heat from exhaust air to incoming fresh air, preheating it in winter and pre-cooling it in summer. This reduces the burden on heating and cooling systems, further enhancing efficiency. For more details about Zehnder’s efficiency, read our blog post, “Zehnder Efficiency: No Matter the Measurement, Zehnder Tops the Scores.”  

3. Zehnder’s Precise Ventilation Control

Zehnder units offer advanced control systems that allow for fine-tuning of ventilation rates based on occupancy, CO2 levels, and humidity. This ensures optimal air quality while avoiding unnecessary ventilation.

4. Zehnder’s Advanced Filtration

Zehnder offers plenty of options for ensuring that you have the right filtration for your needs: Zehnder filter set (left), Zehnder activated carbon filter (top right) and Comfowell (bottom right)

Zehnder units come equipped with high-quality filters that effectively remove dust, pollen, and other allergens from incoming air, creating a healthier indoor environment for allergy sufferers and asthmatics.  In addition, to the excellent filtration offered in the Zehnder unit itself, Zehnder also offers an optional Comfowell system that allows for additional filtration.  The Comfowell can hold either additional standard filters or activated carbon filters. Activated carbon filters contain carbon granules that effectively absorb odors, gases, and VOCs (volatile organic compounds) for improved indoor air quality.

5.    Zehnder’s Ability to Control Humidity

Zehnder systems can help regulate indoor humidity levels, preventing the growth of mold and mildew and creating a more comfortable living environment.

6. Zehnder Reduces Airborne Pollutants and Provides Healthier, More Comfortable Air

By constantly bringing in fresh air and removing stale air, Zehnder units help to dilute and remove indoor pollutants such as VOCs and radon, improving overall air quality.  The fresh air provided by a Zehnder system promotes well-being, concentration, productivity, and healthy sleep.  Optional HEPA filtration captures fine dust and pollen increasing comfort for allergy sufferers. In areas with dry winters an Enthalpy Heat Exchanger (ERV) can prevent the air in getting too dry in winter.  In areas where it is humid, and ERV can remove moisture from the air coming into the home, increasing occupant comfort.

7.    Zehnder’s Quiet Operation

At barely above the sound of a ticking clock at its lowest operational settings, Zehnder ComfoAir q, you can be assured a Zehnder system won’t be a distraction as you go about your day

Zehnder units are known for their quiet operation, ensuring minimal disruption to your daily life. This is especially important in bedrooms and other areas where noise can be bothersome. A Zehnder ComfoAir Q operates at 23 decibels at its lowest settings, which is quieter than a whisper. Zehnder’s quiet operation significantly decreases the likelihood that occupants will turn off the system, ensuring occupants and homes or building continue to benefit from continuous ventilation.

8.    Zehnder’s Easy Installation and Maintenance

Small Planet Supply and Zehnder ventilation experts collaborate to design the best system for a given project, including sizing the HRV system and laying out the ducts. All Zehnder system components are available through Zehnder dealers, so there’s no searching at different stores and distributors for the parts needed to install the system. Builders and HVAC professionals also appreciate that Zehnder offers technical support, making the systems easier and quicker to install, even for professionals who aren’t experienced in HRV installation. Zehnder units are designed for easy installation and maintenance, with readily available replacement parts and service technicians.  

Zehnder ComfoControl App

Zehnder’s COMFOCONTROL app let’s you manage your system both in your home and away from home

To make installation and owning a Zehnder system even easier, Zehnder Q Systems can be paired with Zehnder’s ComfoControl App.  The Zehnder ComfoControl App offers:

  • Local and remote control of your ComfoAir Q and ComfoAir flex system

  • A filter change assistance

  • A comprehensive overview of data from the ventilation unit, sensors and connected devices

9. Zehnder’s Aesthetically Pleasing Design

Zehnder units come in a variety of designs that can complement the style of your home.  Their quiet operation ensures that whichever space you select for the unit, those nearby will barely notice the system’s running while appreciating the system’s design.

10. Zehnder’s Durability and Reliability

Zehnder units are constructed with high-quality materials and backed by long warranty periods, providing peace of mind for homeowners.

11. Zehnder Systems Help Meet Efficiency Standards

As builders move toward building more airtight projects, continuous balanced ventilation (such as Zehnder HRVs and ERVs) are becoming a requirement.  Having a HRV or ERV with high efficiency helps you meet code AND keep heating and cooling bills low.  Two Small Planet Supply blog posts feature work written by Small Planet Supply based on work done by Nick Brown with Build Smart Group on how Zehnder systems work to meet California's energy code ( California's Title 24, The Recovery Ventilator, and You | HRVs and How They Help Achieve California's Title 24 Code Compliance). Although specific to California building code, Nick’s reports provide information that can be helpful for all high-performance building.  To make modeling units into a project even easier, all Q Units have HVI ratings as well as UL listings.
