What can we help you with?

Top 12 questions

Are heat pumps noisy?

The internal wall mounted unit has a fan which is designed to be as quiet as possible during operation.

What payment options are available?

We take all the usual payment options – cheque, direct credit or credit card. We also have easy payment options available through Q Card. At times we have special payment option plans available too - take a look

Can I use my heat pump to cool?

Yes - this is great option for summer.

Can a single Hi-Wall unit heat multiple rooms in the house?

No, the heat pump should only ever be sized for the room it is in so installing in a hallway to service bedrooms is not recommended.

What’s involved in installing an HRV ventilation system?

Your HRV ventilation system is installed by a local team of friendly, professionally-trained electricians. A new power point may be installed if required to connect it and a certificate of compliance is issued for electrical work. They will find a time that’s convenient with you for installation. Then your installer will also talk you through how to get the perfect home invironment(TM) using your new HRV Next Generation ventilation system or one of our innovative ventilation upgrades.

My water has a black look to it.

Flush 20 litres of water through the filter to remove any carbon fines. If the problem persists after 20 litres, the carbon filter may have been over pressurised. A new carbon filter will need to be installed.

Does the HRV ventilation system come with a warranty?

At installation, your HRV ventilation system is warranted for 5 years against fault. In normal use the system will require a filter change every 24-months. Genuine HRV parts are required as part of the ongoing warranty, and to ensure you continue to get the best performance from your system.

How much does an HRV ventilation system cost?

Each home is different – in size, environment, inhabitants etc. Which is why we come to you to take moisture and temperature readings, which we then use to determine the best solution for your home. Our HRV ventilation specialist will talk you through how everything works, provide a price and if you'd like to go ahead, the installation is planned for whenever suits you.

How does ventilation help to create a more comfortable home?

The HRV home ventilation system installed in your roof space creates positive air pressure in your home to reduce excess moisture. It also helps to improve your home's indoor air quality by filtering most of the common airborne asthma and allergy triggers from the incoming vented air.

How many heaters do I need for an average three bedroom house?

HRV can pop around to your house to provide a free home assessment and discuss your heating requirements, as this can significantly vary depending on building design.

I've just moved into a home with an HRV ventilation system, what do I do?

How do I use Burnt Toast Mode?



Pressing the Burnt Toast Mode button on your control panel switches your system to maximum ventilation for one hour. To return your system to its previous setting before the hour is up, just tap the button again. By forcing air and maximising air movement this can assist with clearing bad smells and clearing excess moisture on walls and windows.
