Why choose Continuous Gas Hot Water?

Cost Efficiency

You only pay to heat the water you use as you do not need to store hot water as you would with an electric cylinder, this will significantly reduce your annual running costs.  Gas is supplied through natural gas piped from the street or refillable LPG bottles.

Endless Flow of Hot Water

No more cold showers!  There will always be enough hot water for the whole family, whether it be when showering consecutively or multiple showers in the household running at once and on mains pressure.  This is the perfect option for families and commercial situations such as gym locker rooms or accommodation.

Space Saving

Where space is limited, a continuous flow system is the perfect solution. Because it doesn’t require a hot water cylinder, it takes up far less room. Also, gas units are most usually fitted on an outside wall, allowing more space inside the house.


This special is based on supply and installation of either the Rinnai A26 Gas Heater or the Rheem 27 Gas Heater.
