Instantaneous Gas Hot Water in the Southern Highlands
Instantaneous gas hot water heats water only when a tap is opened, so there is no tank to run cold and nothing kept hot while you are at work. We supply Rinnai instantaneous gas hot water systems to homes in Bowral, Mittagong, Moss Vale, Berrima and across the Highlands.
Hot water that does not run out
A continuous flow unit heats water as it passes through, so the fourth shower is as hot as the first.
Nothing heating while you are out
No tank means no standing heat loss. Gas is only burned while hot water is actually being used.
How instantaneous gas hot water works
Open a hot tap and the unit senses the flow, fires its gas burner and heats the water on its way through a heat exchanger. Close the tap and it stops. Rinnai calls this continuous flow hot water, and the unit is compact enough to sit on an outside wall where a bulky tank once stood.

Why Highland homes choose instantaneous gas hot water
Three things that matter when you are weighing up an instantaneous gas hot water system.
Endless supply
With no tank, the supply is limited by flow rate rather than volume. Pick the right size unit and back-to-back showers, a bath and the dishwasher can all run without a cold surprise.
Precise temperature
Rinnai units hold the water at the temperature you set, and optional controllers in the kitchen or bathroom let you dial it in exactly. That also means less scalding risk with young children.
Small footprint, long life
The unit is roughly the size of a small suitcase and mounts on an exterior wall. With no tank to corrode, continuous flow units are known for long working lives.

The questions we hear most from Highland homeowners considering an instantaneous gas hot water system.
Still have questions?
We're happy to talk it through, with no pressure.
Does instantaneous gas hot water work well in a cold Highlands winter?
Yes. The burner heats incoming water to your set temperature whatever the season. In winter the water arriving at the unit is colder, so the flow rate at full temperature drops a little. Choosing a unit with enough capacity for your household takes care of that.
What size instantaneous gas hot water system do I need?
Rinnai sizes units by litres per minute. A one-bathroom home is usually fine with a smaller unit, while two or more bathrooms running at once need a higher-flow model. We size to your home rather than a chart.
Is instantaneous gas hot water cheaper to run?
Gas is only used while hot water is flowing and nothing is kept hot in a tank, so a household that is out all day usually sees lower gas use. Your actual saving depends on your tariff and how much hot water you use.
Do I need natural gas, or can I use LPG?
Either. Rinnai makes natural gas and LPG versions, so homes outside the town gas network can still have instantaneous gas hot water from bottles.
Which instantaneous gas hot water brand do you supply?
Rinnai. Their continuous flow units have been the backbone of instantaneous gas hot water in Australia for decades, and we know the range well enough to recommend the right model rather than the biggest one.
