Our Services

At Treadies, our team is committed to delivering high-performance solutions that align with Passive House standards, including:

Heat Recovery Ventilation (HRV) Installation & Maintenance

We offer complete HRV solutions that efficiently exchange stale indoor air with fresh outdoor air, recovering heat in the process. Our systems ensure optimal indoor air quality without compromising on energy performance.

Energy Recovery Ventilation (ERV) Installation & Maintenance

Our ERV systems go a step further by transferring heat and humidity, helping maintain comfortable humidity levels indoors. They are ideal for climates with varying humidity levels.

System Upgrades & Retrofits

Already have a ventilation system but want to improve its performance? We offer expert upgrades and retrofits to enhance energy efficiency and compliance with Passive House standards.

Frequently Asked Questions About HRV & ERV Systems

Below we’ve answered some of the most common questions about HRV & ERV systems to help you make an informed decision. Got more questions not covered here? Feel free to reach out to us via our contact page. We’re here to help you find the best cooling solutions tailored to your needs.

What’s the difference between HRV and ERV systems?
HRV (Heat Recovery Ventilation) systems transfer heat between incoming and outgoing air to maintain indoor temperature while providing fresh air. ERV (Energy Recovery Ventilation) systems do the same but also transfer moisture, helping to control indoor humidity levels.
Why is ventilation important in a Passive House?
Passive Houses are airtight to maximise energy efficiency, which makes proper ventilation essential for maintaining indoor air quality. HRV and ERV systems ensure continuous fresh air circulation without significant energy loss.
How do HRV/ERV systems improve energy efficiency?
By recovering heat (and moisture in the case of ERVs) from outgoing air, these systems reduce the energy needed to heat or cool incoming air, lowering overall energy consumption.
How often should HRV/ERV systems be maintained?
We recommend servicing your system at least once a year, including filter replacements and performance checks, to ensure optimal efficiency and air quality.
What’s the cost of installing an HRV or ERV system?
Costs vary depending on the size of your Passive House, the complexity of the installation, and whether you choose an HRV or ERV system. We provide customised quotes after an initial consultation.
