Electric Hot Water Heaters
Electric Water Heaters - Compact & Decentralised Solutions to Help You Save Energy
Every day more family houses, apartment buildings, and commercial spaces are using compact and decentralised electric hot water systems.
The reason usually is that they're trying to solve one of two common problems:
- They have a tap that's far away from their main hot water system. This results in a lot of cold water runoff (going down the drain) before any hot water makes it out of the tap.
- They're looking for a compact hot water solution because they just simply don't have the space for a bulky hot water tank (and they don't want the maintenance or the energy losses that come with them either).
So they choose a compact and easy to install electric hot water system. These compact water heaters can be conveniently installed extremely close to the location of where the hot water is used - and don't take up much space in cupboards or under benchtops.
And when the water heater is placed close to the off-take tap, it minimises the length of pipe required to deliver hot water to the outlet, so delivers hot water to the outlet faster - and importantly, without the usual water wastage we're all familiar with when waiting for hot water. Plus, heat energy losses from the usual hot water pipe runs are greatly reduced (i.e. when the water cools down in the pipe runs between tap uses).
There are two main types of decentralised electric water heaters:
Instantaneous Water Heaters
Heat the water instantly to the desired temperature.
- Great for medium sized hot water usage with multiple taps or draw-off points - for example a shower and a sink.
- Very compact, reliable, and maintenance free.
- Usually require a dedicated electrical circuit - so best installed in new buildings, or where replacing existing instantaneous electric hot water units.
- Available in single or three phase.
Compact Storage Heaters
- Store 5, 10 or 15L of water in a tiny tank under your bench or sink.
- Best used for only a single draw-off point, e.g. under your kitchen sink, or for a tap that is very far away from the main hot water system.
- Can be powered from a standard power point (GPO) - so can be easily installed in existing buildings or new buildings.
- Available in mains-pressure models (use your own tap), or open-vented models (special tap comes with the installation kit and must be used). The open-vented models have the advantage of not requiring a drain point next to the unit for a pressure relief valve.
- Available in single phase only.
EnergyLabs offers you ready to go installation kits - making it easy for you to install and get your hot water heater up and running:
INSTANTANEOUS
SMALL instantaneous hot water heaters are suitable for up to 1 bathroom.
MEDIUM instantaneous hot water heaters are suitable for up to 1 - 2 bathrooms.
LARGE instantaneous hot water heaters are suitable for up to 2 bathrooms.
COMPACT STORAGE
SMALL mains pressure compact water storage heaters are suitable for 1 outlet (SHC type).
MEDIUM mains pressure compact water storage heaters are suitable for 2 outlets (SHC type).
SMALL & MEDIUM open vented compact water storage heaters are suitable only for 1 outlet (SNU/SNE type - special outlet tap that is included in the installation kit)

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)
