How Can Ventilation with Heat Recovery Help Your Home?

There are plenty of improvement projects and renovations that you can make to a home, whether they are done during the build process or later on. With some of these projects and decisions, the benefit is clear from the start, and it’s easy to understand why you would make the choice. Then there are other systems, projects, and items in the home that can be just as beneficial, but aren’t always given the recognition they deserve.

A great example of just such a system in the home is ventilation with heat recovery. What exactly is this and how can it help your home? Here’s a breakdown of all the basics.

The Move to Tighter Insulation Hasn’t Helped in All Respects

In order to fully understand how this heat recovery ventilation system works, it’s important to understand why it’s needed.

It was during the 1970s that people started to understand that the way homes were being built wasn’t exactly energy-efficient in terms of insulation. Too much air was escaping and entering into the home, which means more money and energy was being spent to keep it at a consistent temperature. The answer was clear – insulate the home tighter and stop that air from escaping.

This move led to windows that were tighter and double or even triple-paned, modern siding, better vapour barriers, caulking of cracks and seals, and so forth. The result was that no air escaped, which was good – or was it?

Where Does the Moist and Stale Air Go?

This move towards tighter insulation to seal in the air means that the moist and stale air that naturally accumulates in a home – especially in washrooms and kitchens – has nowhere to go. It just hovers and lingers in the house. Moisture can even go on to cause issues with mildew, mould, fungi, bacteria growth, and dust mites.

The simple solution is to open a window to allow circulation, but that’s not always practical or doable, especially in the winter. This is why the heat-recovery ventilator (HRV) has now come into light as a balanced solution to home ventilation.

The way these systems work is that they have two fans; one brings in fresh air from the outside and one takes out the household air. During the exchange, the core is able to transfer heat to the air – warming it up. And what’s even better is that the incoming and outgoing air streams never mix. There is a constant flow and exchange of air that keeps the home fresh and free of smells, stale air, and moisture.

You Can Purchase Your Own Home Heat Recovery Ventilation System

As BPC Ventilation ( points out, where it used to be that purchasing one of these systems for the home was expensive and hard to access, today that is no longer the case. You can find systems for sale that can be installed by homeowners with basic DIY knowledge, or you can hire a professional tradesperson to do the installation.

It’s for these reasons that more homeowners are looking into whether or not their home is equipped for an installation.
