Rinnai Hot Water Systems

rinnai gas hot water Rinnai has a valid claim to be true pioneers in the home heating game, having launched Australia’s first fully electronic gas continuous flow hot water system back in the ‘90s. For a population used to tank-based systems, this instantaneous hot water system was a revolutionary leap forward, and millions of Australians have never looked back.

The major advantage of an instant hot water system is that you have total confidence that your hot water would never run out. And with Rinnai’s Electronic Water Heater Control systems mean you have total control over your water temperature at all times. 

Another advantage this type of gas water heater holds over an electric hot water system with a hot water tank (or similar gas hot water systems for that matter) is the lack of the tank itself. As there is no standing water to keep warm, less energy is used. Any electric water heater will generally be more expensive to run. 

Storage based heaters can sometimes be more suitable than an instant heater, and depending on the size of the install and the amount of use can sometimes work out cheaper. It really depends on you and how you will use it. 

That’s why we’ve covered a range of Rinnai hot water systems below so you can weigh up what might work best for your needs. We haven’t covered them all so be sure to get in touch if you have any questions!

Rinnai’s tankless heaters are a little more, although for small homes the upfront coast can work out roughly the same as the tank based heating systems.
