HRVs & ERVs

HRVs & ERVs

When you live in Ottawa, using a heating system throughout the winter is completely necessary as Ottawa winters can be particularly unforgiving. Unfortunately, although your home will be warm throughout the colder months, heating systems have their own downside: air quality. Many Canadians have reconciled that they have to choose between having a warm home or having fresh air because opening a window in the dead of winter is just not an option. If you want to have the best of both worlds with warm and high-quality air, you may want to consider investing in an HRV or an ERV. Here’s what you need to know about HRVs and ERVs in Ottawa.

What Is an HRV? 

An HRV, or a heat recovery ventilator, works to keep your home supplied with endless fresh air from directly outside. The HRV will expel stale warm air from your home while using its heat to warm the fresh cool air from outside, resulting in fresh warm air circulating through your home and increasing your home’s overall air quality without cooling your home or leaving it to feel drafty. 

Why Choose an HRV? 

What would make an HRV a valuable option for your Ottawa home over an ERV is if you live in a cool climate that has an excess of humidity during the winter.  An HRV will get rid of any excess moisture in your home’s air. With an HRV, your home will have a constant supply of fresh, heated air without an excess of moisture and humidity.

What Is an ERV?

An ERV, or an energy recovery ventilator, works similarly to the HRV in that it recovers heat to warm the home, but it also works to harness the energy trapped in humidity to conserve energy. For homes with an excess of outdoor humidity, an ERV will limit the amount of humidity allowed in the home, and for homes with low indoor humidity, an ERV will limit the amount of humidity that can leave your home.

Why Choose an ERV?

What would make an ERV a valuable option for your home in Ottawa over an HRV is if you live in a cool climate without an excess of outdoor humidity. An ERV works like an HRV, however, it uses the humidity in the air to conserve energy and maintain the moisture in your home, meaning it’s very efficient and effective in areas that don’t have an excess of humidity.

The Difference Between an HRV And an ERV

While an HRV and an ERV are very different when Ottawa residents are looking for the best system for their regional climate it’s essential that they fully understand what makes each system unique. Humidity is the factor that differentiates HRVs from ERVs, as they both work to replenish the home with fresh air, but only an HRV will eliminate the humidity in the air of your home, making it a better choice for cold climates with high outdoor humidity.

Ventilation is a necessity. But what is the most cost effective way to ventilate while retaining the energy used for heating and cooling? Team Harding carries a wide range of Venmar air exchangers with Heat Recovery (HRV) and Energy Recovery (ERV) technologies.

When To Turn On An HRV For The Winter?

Keeping a home comfortable during the winter can be tricky. On one hand, we want to conserve energy to ensure we’re getting the most out of our heating and our electric bills, and on the other hand, during the winter we tend to miss the feeling of fresh air through our house. How do you […]

Should I Turn Off My HRV In The Summer?

As the warm weather continues to ramp up and homeowners across Ottawa begin to transition from using their heating system to their cooling systems, they are often unsure about what to do with their HRVs. Although an HRV can drastically improve your indoor air quality during the winter, that doesn’t necessarily mean you should turn […]

How to Use and Maintain Your HRV System

The harsh Canadian winters can take a serious toll on your indoor air quality, which can have negative impacts on your health and the condition of your home. HRV systems can drastically reduce the discomfort and damage caused by dry, stale indoor air, but not if they’re in disrepair, so we’ve created a checklist for […]

When to Turn On an HRV System

We always encourage homeowners to make sure their homes are as airtight as possible to increase the efficiency of their HVAC systems, but that too presents a problem. If your home is airtight, it will keep you from losing heat during the winter, but it also means there is a limited amount of fresh air […]

Benefits of a Clean Comfort HRV System

A Heat Recovery Ventilator (HRV) can help homeowners eliminate the frustrating problem of indoor window condensation. In new home construction, there is little natural ventilation as building techniques have advanced to reduce air leakage and increase energy efficiency. Without anywhere to escape, moisture is trapped in the home and condenses on the glass. However, with […]

Eliminate Winter Window Condensation with an HRV System

A common frustration for many Ottawa homeowners is window condensation. This issue has become more widespread as home construction has focused on reducing air leakage and increasing energy efficiency. An unintended consequence of improved building techniques is that natural ventilation has decreased and moisture filled air gets trapped in your home. When the window cools […]
