Description
Description
Designed and manufactured in Australia, the Rinnai Enviroflo range of Electric Integrated Heat Pump hot water systems deliver a comprehensive set of installation configurations perfect for the various site specific requirements around the country. The innovative controller works to maximise hot water availability while using up to 75% less energy*, compared to a standard electric storage tank. They are available in a range of capacity sizes, and can be equipped with magnesium or hard water anodes to further customise their capabilities to suit the application.
A standard feature of the Rinnai Enviroflo is the single element boost, that allows the product to be used in high demand applications or even cold ambient conditions, meaning you will enjoy always hot water all year round.
Built locally to outlast the tough Australian conditions, these tanks have been designed and tested to operate with water pressures up to 1000kPa, much higher than normal. Best of all, they are lighter in weight to aid quick and safe installation whilst having a minimal impact on the environment.
* Energy saving of up to 75% based on a Rinnai Enviroflo 250ltr/315ltr Heat Pump, when compared to a standard electric water heater of the same capacity during peak winter load in Zone 1 based on AS/NZS4234. Savings will vary depending upon your location (Zone 1-5), type of water heater being replaced, hot water consumption and associated fuel tariffs.

At Rinnai, we’reall about comfort
For over 50 years, Rinnai has
supplied Australian homes with
a range of appliances that help
people lead comfortable, safe and
efficient lifestyles.
Being driven to create comfort
means that we really care about
our products and your experience
from start to finish. We’re focused
on developing products with the
latest technology and our level of
quality is second-to-none, so you
can rest assured knowing Rinnai
will deliver





























































Federal Small-Scale TechnologyCertificate (STC’s)
Enviroflo’s innovative design allows it to be eligible for Grants through the Federal Governments
Small-scale Renewable Energy Scheme, generously covering a proportion of the up-front costs of
purchasing and installing the system. These grants are called Small-scale Technology Certificates
(STC’s) and are offered based on how sustainable a hot water system is. Your STC rebate value will
depend on your installation location, see the map above for your geographic Zone locations.

How it works
Using advanced refrigeration technology, the Rinnai
Enviroflo Electric Heat Pump naturally moves thermal heat
energy and transfers it to the stored water. The higher the
ambient air temperature, higher the system efficiency, this
is also known as Coefficient of Performance – COP.
1. Compressor
The compressor is the central hub of the heating cycle
which distributes the refrigerant between two heat
exchange coils to facilitate efficient heat transfer.
2. Dual Protection Heat Exchanger
The highly efficient design of the heat exchanger safely
transfers thermal heat from the refrigerant to the stored
hot water.
3. Intelligent Controller
Locally design and manufactured, this clever controller
continually monitors and adjust system parameters
ensuring optimum performance and system reliability.
4. Integrated DC Fan and Evaporator
40% more efficient and smaller than conventional
AC fans when coupled with our in-house evaporator
means reduced materials during construct and a lighter
assembled weight.
