If you’re ready to invest in a new hot water heater you might be considering a continuous flow system. Continuous flow hot water heaters do exactly what their name implies: deliver a continuous flow of hot water. If you’re not sure if that’s the right hot water solution for your home, read on to find out more about it.
Will a continuous flow hot water heater work in my house?
A continuous flow hot water heater can be installed in your house if you can access a gas energy supply – either through gas mains or LPG tanks. All continuous flow hot water systems run on gas.
As well as having access to gas, there are other factors that are important to your decision. How big your house is, the number of people living in your home, and the number and location of your bathrooms will also impact how effective a continuous flow hot water heater can be. The right solution may also differ if you’re installing on a commercial vs. residential property.
Do you have the right water pressure for a continuous flow hot water system? Continuous flow hot water systems like Rinnai Infinity require a minimum pressure of 1 bar (100 kpa), with the ideal water pressure at 300-500 kpa.
All continuous flow water heaters require power to operate but if you’re living off-grid or preparing for power outages you could explore the Bosch Hydroflow Range. It is possible (but not recommended) to run your continuous flow system on solar power and generators as long as the power is continual with no fluctuations.
Providing electricity for continuous flow hot water heaters with an off grid power supply could void the warranty. Check with your supplier for details.
How much does it cost to operate a continuous flow hot water heater?
The cost of operating a continuous flow hot water heater depends on how much hot water your household uses. The cost directly correlates to your usage – unlike with hot water storage systems where you’re paying to heat the water in your tank even if you’re not using it.
Where is a continuous flow hot water heater installed – inside or outside?
You can install a continuous flow hot water heater either inside or outside your home or business – there are models available to suit both options. Your installer’s preference will normally be to place your hot water heater on an external wall. If that’s not possible you can explore internal solutions.
How long does it take to install a continuous flow hot water heater?
The time it takes to install a continuous flow hot water heater depends on whether you’re replacing an existing unit or installing one for the first time.
As a rough estimate you can expect a replacement installation to take between 2.5 and 4 hours. If your existing unit is very old this may take longer if you need pipes to be altered to be compatible with the new unit.
Installing an external continuous flow hot water system into your home or business for the first time usually takes between 7 and 10 hours. If you opt for an internal unit it can take longer due to the flu/ventilation requirements.

How often should I get my Continuous Flow Hot Water Heater serviced?
You should get your continuous flow hot water heater serviced every 2 years. This helps to protect any warranty on the hot water system and also makes sure it’s operating safely and all parts are in good working order.
Servicing your hot water system regularly can extend its life and could help you avoid more costly repairs caused by an unexpected part failure.

How to check your continuous flow hot water system is safe after an earthquake or power cut
After a heavy earthquake we recommend having your gas system checked for leaks by a professional gas fitter like East Coast Plumbing and Gas.
If you experience a power cut and your unit is not working when the power comes back on; try turning the power off for a few minutes and then back on again. Run a tap and see if your hot water is now working. If it’s still not heating, book in a site visit and one of our experts will come and help.
