FAQ
- What else do I need to complete the installation? Apart from some screws, power, and somewhere to drain a bit of condensation from in the central unit, nothing, we send out a complete kit that can be installed immediately. To install the optional HRV system control panel (supplied in the kit), a low voltage cable is required from the wall mounted control panel to the central HRV unit.
- What is the warranty on the HRV unit and the system? Stiebel Eltron provides a 2-year warranty on all components supplied.
- How do I know where to put the vents and install the different system parts? We offer a free design service with every purchase – just supply us with your building plans and we send you back the design. If you request the design before purchasing, a $179 fee applies. This fee will be refunded upon payment for the product order.
- What happens after I order the unit and pay? We will be in contact with you to confirm the order, delivery address and timeframe, system design (if required), and any other questions you may have.
- How long until I receive my order, and is there a delivery fee? Within Australian state/territory capital cities delivery is free (excluding Darwin), and your order will usually arrive within 5 business days. For orders outside of capital cities, we offer a flat-rate fee of $200 for delivery.

When do DIY Installation Kits make sense and why
Why is it easy to install?
You don’t need any ducts – you will get a few in-wall units which talk to each other and simultaneously extract stale air and supply fresh air into the room, while recovering as much energy as possible during the process.
Decentralised heat recovery ventilation solutions are ideal for retrofitting to existing buildings, or new buildings that have minimal ceiling or roof space available. This is because with a decentralised system there are no ducts to run – there are simply a few in-wall units which talk to each other and simultaneously extract stale air and supply fresh air into the room, while recovering as much energy as possible during the process.
How is the EnergyLabs’ Complete Heat Recovery Ventilation Kit different to standard ventilation?
There are two main types of ventilation systems in Australian buildings: extraction-only air systems and supply/extract air systems.
The simplest and cheapest method for ventilation is an extraction-only air system. This is the system you will recognise from almost all houses in Australia – unwanted air is removed via ducts from areas such as the kitchen, bathroom and toilet. But the air that is extracted and pushed out from the building must then be replaced somehow… and this replacement air from outside has traditionally just seeped its way into the building via the small openings and cracks around windows, doors, ceiling & roof, etc.
Now in theory this simple and cheap way works, but the air that is getting sucked into the house through all the openings and cracks is costing us money. In winter this air is cold, and therefore we have to pay to heat it up… and the same is true in summer – the air coming in is hot, and we have to pay to cool it down.
But unlike an extraction-air system, a supply/extract system first strips the unwanted extract air of its thermal energy, and then it transfers the majority of this energy to the fresh air that is being supplied into the building. And to achieve this a pair (or pairs) of decentralised heat recovery ventilation units can help you.
How does the whole EnergyLabs’ Complete Heat Recovery Ventilation Kit work? (and why it will save you money)
For example in winter the outside air may be 7°C, but inside your home it’s a comfortable 21°C. A simple extraction-only air system would exhaust to the outside 21°C air from your house, and then draw in 7°C air from outside… which can be uncomfortable for those inside, but most of all costs you money to heat up this cold air to 21°C again.
However, a supply/extract air system would in this situation extract the heat from the stale 21°C air first, and only then exhaust it at ~9°C. The fresh incoming cold air from outside would be at 7°C before it passes through the special crossflow heat exchanger, but then it’s supplied into your home at 19°C… meaning you don’t experience discomfort and you dramatically save on your heating bills, while having high quality (and filtered) fresh air supplied throughout your home.
It’s important to remember that heat recovery ventilation systems do not actively heat or cool your home – they only help you keep more of the energy you already have in your home while enjoying clean fresh air and minimising your energy bills. (Some HRV systems do however have night purge, which during summer allows you to pump out any warm air from inside your home, and replace it with cool night air)
