Instantaneous Hot Water Systems

For Gas Storage Hot Water Systems please view at the following link Storage Hot Water Systems

For Electric Storage Hot Water Systems please view at the following link Electric Hot Water Systems

An instantaneous hot water system heats only as much water as you need, when you need it.

Most instantaneous hot water systems  use gas, but electric models are available too.

As there are no heat losses as with water stored in a tank, they’re often cheaper to run than storage systems.

Electric hot water systems may have higher running costs because you are charged whenever they are in use.

The size of instantaneous hot water system you need (flow rate in litres per minute) depends upon the number of hot water outlets the heater has to serve, more than on the number of people in the household. As a general rule, for a two-bathroom house you need a flow rate of about 22–24 L/min. You can talk to us, your Know Hot Water Specialist to find the right capacity for your home.

Please find below a range of instantaneous hot water systems that will suit different requirements and budgets. As we are the hot water specialists, we have access to every hot water system on the market. If it’s not on the website, call us and we’ll give you a very competitive quote.

Don’t go psycho!  Call 1800 NO PSYCHO (66 779246)

We don’t want our competitors to see how cheap these systems are. Please call us for Perth’s guaranteed lowest prices, and same day installation.
