Instantaneous / Continuous Flow Hot Water

An instant gas hot water system or a continuous flow hot water system is a tankless hot water heater. This means consistent hot water when you need it. These systems are generally wall-mounted and compact unlike a hot water tank that are floor-mounted and large.

Instant hot water systems give you the convenience of having extra guests and not running out of hot water. Plus, running a bath after a long day without worrying if there is enough hot water.

Most instant hot water systems use gas however electric models are also available. Generally, they can be cheaper to run compared to storage tanks, as there are no heat loss issues.  A 6 or 7 Star rated instant gas hot water works more efficiently which will save money, energy and reduces CO2 output.

How Do Instant Gas Hot Water Systems Work?

As an instant gas hot water system, it doesn’t hold a tank. It warms the water as it passes through a heat exchanger when hot water is needed. 
This way, there is a consistent and endless supply of continuous flow of hot water when you need it.

Why Make The Switch
To Instant Hot Water?

If you are looking to make an investment to your home, a tankless water heater is a good place to start. Getting hot water when you need it while also saving energy is a win-win proposition.

Tankless water heaters take up much less space than storage water heaters (hot water storage tanks) as they heat the water directly. Traditional storage tank are kept full of water at a minimum of 60°C to prevent bacterial growth, tankless water heaters only heat the water when you need it.

When you turn on the hot water, the cold-water travels through a pipe and into the tankless water heater unit where it is heated by a gas burner or an electric element. This allows you a constant supply of hot water.

On average, tankless water heaters can provide 7 to 14 litres of hot water per minute. Also, gas-fired tankless water heaters can produce higher flow rates than electric models.

Chris and the team took on a niche home networking job for me to cable up 12 runs across 5 rooms. Fully accredited cable installation, fantastic cable management and wouldn't rest until all cables were terminated at the patch panel and fully passed.... I couldn't be happier. I've used Alliance before for all the air-con units in the property and they came through again for a slightly different job than the norm. From the start I was consulted with on different options, fantastic communication throughout and an absolutely stellar end result. Massive thank you to Chris who was present throughout and handled the job with ease, though I know it wasn't simple. Thanks again team!read more
Difficult job, but fantastic result.
This is the second time we’ve used this business. Excellent service from start to finish. Very happy to recommend them
Adian and his offsider (apologies forgot his name) were the most professional tradesmen to ever put foot on my premises. Nothing was a problem for them and they made us feel most at ease. Because of these two I would always recommend Alliance air... conditioning to anyone. They were a credit to their organisation. 5 more
Alliance technician Hamid came to our home & thoroughly diagnosed the issues with our 8 yr old aircon system which required parts and cleaning. Hamid returned a few weeks later to complete the work to our total satisfaction. It was not cheap costing... over $4000 but the mould & dirt that was extracted from our 5 units was incredible. Extremely satisfied & will call Alliance/Hamid & his partner back every 12 mnths from now on.Heather & PeterKingsfordread more
The ACC team did a fantastic job installing our multisplit in our apartment.Aron, Andres R, Ivan T and Tommy produced high quality workmanship and consulted us where we wanted all parts located.My favourite aspects were that they made it look... good (minimising visual impact) and cleaned up after installing.I'm so happy we heard about them from neighbours. I would definitely go with them again if we needed aircon in the more
Great experience with Alliance Climate Control. They were very professional from the first point of contact all the way through to the installation. I would highly recommend them to anyone.
Andres and Ivan were professional, respectful and ensured that area was protected during work. And they cleaned up well at end.
