Heat Recovery Ventilation

Q: How long do HRV systems last?

HRV systems last for around 10 - 15 years on average in Australia but with proper maintenance that can push to 20 years and beyond. Annual checks are a good way of increasing its lifespan.

Q: Does HRV use a lot of power?

HRV systems do use power, but the amount they use depends on how many fans are needed to run them at different times of the year. In general, HRV systems use less power than other types of ventilation systems because they're constantly running and recovering heat from inside the house as well as the outside air.

Heat Recovery Ventilation, also known as HRV, has been shown to be a safe and effective way to deliver fresh air into your home or office in Australia. The system works by taking air from inside the home, warming it up and then returning it to the rooms. ArchiPro features many different types of HRV systems including centralised systems, dual operation, and ductless HRV systems, so you can choose the one that best fits your needs and budget.

Featuring the best heat recovery ventilation in Australia

ArchiPro features high-quality heat recovery ventilation systems in Australia that are designed with efficiency and reliability in mind. There are many different types and sizes of heat recovery ventilators available including centralised systems, dual operation and ductless models, so it’s important to know what features are important when making your choice. As an important part of our wider range of ventilation systems, HRV systems are a great innovation to include in any modern home or business in Australia.

Types of heat recovery ventilation

Centralised systems

Due to their size, centralised HRV systems provide the greatest air recovery efficiency. Typically, the equipment has two sizable wheels, one of which sucks in the stale air and the other of which draws in outside air. The stale exhaust is brought into contact with the fresh air by the rotating wheel, heating it.

Dual operation

A dual operation ventilation system, often known as an HVAC (Heating, Ventilation, and Air Conditioning) system, serves a dual purpose. It efficiently provides a comfortable indoor climate regardless of outdoor weather conditions. The system operates by pulling in outside air and then either heating or cooling it to meet the desired indoor temperature.

During warmer months, the system works by extracting warm air from inside the building and replacing it with cooled air from outside. Conversely, in colder months, it draws in cold air and warms it before it circulates indoors. This temperature-adjusted air is then distributed evenly throughout the home or office via a series of ducts and vents, maintaining a consistent and comfortable environment.

The ability to switch between heating and cooling makes these systems extremely versatile, and they are designed to operate with efficiency in mind. They often include thermostats and sensors that monitor the indoor temperature and make automatic adjustments to the airflow and temperature, ensuring optimal comfort while also conserving energy. This makes a dual operation ventilation system an all-in-one solution for year-round indoor climate control.

Ductless HRV

A ductless heat recovery ventilator (HRV) capitalises on the energy efficiency of traditional HRV systems while eliminating the need for ductwork, making it ideal for use in conjunction with passive ventilation systems. It's particularly useful in retrofit situations or in buildings where installing ducts is impractical or too costly.

The core of a ductless HRV is the heat exchanger. As stale air is expelled from the building, it passes through one side of the heat exchanger. At the same time, fresh air from outside is drawn in and passes through the other side of the heat exchanger, but in a separate channel. The two streams of air never mix, yet thermal energy is transferred from the outgoing warm air to the incoming cool air in the winter, or vice versa in the summer.

This exchange pre-temperatures the fresh air to a level closer to indoor conditions, making it an energy-efficient way to ventilate a space. Since it's ductless, the system typically works with individual units in each room or area, making it scalable and flexible. These units leverage natural air movement from wind and convection, so they're quieter and use less energy than systems with mechanical fans. They're ideal for spaces that need independent temperature control or where occupants have different ventilation requirements.

The advantages of high-quality heat recovery ventilation

High-quality heat recovery ventilation helps to ensure that you are getting the clean air you need to live a healthy lifestyle. It also keeps your energy bills low by ensuring that your home is at its most comfortable temperature. The benefits of high-quality heat recovery ventilation include increased comfort and energy savings, reduced allergens, dust and pollen in the air and better indoor air quality. High quality HRVs will keep your space cooler for longer and are more likely to work efficiently for a long time, compared to lower quality options.

How to choose heat recovery ventilation that’s right for you

When choosing heat recovery ventilation, there are many factors you should consider. First, determine if your home has adequate ductwork for installing a heat recovery system. If not, a ductless HRV system might be the best option for you. The system will need to be installed in an area where it will be able to transfer heat from one area to another. If there is not enough space for this, then you may need to make some modifications before installing a heat recovery system. Next, you'll want to consider how much space is available for installation and what kind of airflow it will require. Heat recovery ventilation is often used in large rooms with lots of windows or doors where there is plenty of airflow. If these conditions exist in your home, then this type of system could be ideal for you! You'll also want to consider whether or not the system will require any electricity or gas lines before installing one yourself. In addition to heat recovery ventilation, mechanical ventilation systems offer numerous benefits, such as improved indoor air quality, reduced humidity levels, and enhanced control over airflow, ensuring a healthier and more comfortable living environment.

How efficient is heat recovery ventilation?

Heat recovery ventilation (HRV) is one of the most efficient ways to ventilate a home. It works by recovering heat from the exhaust air, which means that you are able to use less energy than with an ordinary ventilation system.
