Why Choose an Instant Gas Hot Water System?
Instant (also called continuous flow or instantaneous) systems heat water only when a tap is turned on — giving you:
-
Unlimited hot water – never run out again
-
Lower energy bills – no standby losses like storage tanks
-
Compact design – perfect for small yards or wall mounting
-
Fast heat-up time – hot water in seconds
They're ideal for homes with 1 to 3+ bathrooms and are particularly efficient when paired with 5+ Star gas models.
