Instant Gas Hot Water Systems

Instant Gas Hot Water Systems

Often referred to as "instantaneous", a Continuous Flow Hot Water System heats only as much water as you need, when you need it. They aren't truly instantaneous - it can take a few seconds before hot water starts flowing from the tap, especially when there's a fair distance of pipe between the hot water system and the tap.

Instant Gas Hot Water Systems
As there are no heat losses as with water stored in a tank, they're often cheaper to run than storage systems. The size you need (flow rate in litres per minute) depends more on the number of hot water outlets the heater has to serve than on the number of people in the household.
