Energy Star Ratings
Energy Star ratings are an industry wide independent rating
that gives an indication of how eciently a heater operates.
The more stars, the greater the eciency. Typically Portable
gas heaters have around 5.9 Stars with the majority of ued
heaters around 4.0 to 4.5 Stars. Some older type heaters are
not as ecient, however they still perform extremely well
with large heat outputs.
Running Costs
Rinnai gas heaters are designed to be highly ecient, and
when used correctly, are a very economical form of home
heating. The running cost of gas heaters compare very well
to other forms of heating. Straight electric heating is by far
the most expensive, with both gas heaters and electric
reverse cycle heaters comparatively less expensive.
When comparing diering forms of heating in relation to
running costs, it is important that the comparison is based
on the same kW output of heat. Once we are comparing
‘apples with apples’, the calculation of the running cost is
then based on the energy used (kW input) to achieve that
output. The actual taris that are charged are listed on
energy bills.

Important Tips for heater selection
Very Cold Zone: 1 kW output will heat approx 8.5m
2
Cold Zone: 1 kW output will heat approx 10m
2
Cool Zone: 1 kW output will heat approx 13m
2
Mild Zone: 1 kW output will heat approx 16m

i.e. a 7.3 kW output heater in a Cool Zone will heat approx 95m

The MJ input of heaters should
not be used for comparison.
The kW output is the only true
‘apples for apples’ method.
As an example, a 25MJ input,
5.9 Star heater has a larger
heat output than a 25MJ 3.1
Star heater.
Selecting the right heater
It is very important that careful consideration is given to selecting the correct model/size of any heater. Critical factors such as the
area to be heated, along with specic design and insulation characteristics of a home must all be considered. On the next page
there is a heater selector relating to correct sizing or you can use our on-line version at www.rinnai.com.au. In general, heater sizing
should be based on the kW output of the heater. As a very rough guide to heating performance (based on our heating zones):

Notes
1. Gas and electricity tarris, Origin Energy for VIC metro from 1 July 2011, downloaded 19 Jan 2012: 18.48 c/kWh and 1.60 c/MJ.
2. Daily and yearly usage based on Australian Standard AS4553 “gas space heaters”.
3. Greenhouse gas emissions: Greenhouse gas emissions from electricity are approx 3 times greater than those for Natural Gas.
Gas cost / MJ 0.016
Electric cost / kWh 0.1848
The Environment
In Australian homes, heating & cooling amounts to around
23% of household energy use – second only to hot water.
Gas is one of the most greenhouse friendly fuel sources
available and selection of a Rinnai gas heater can assist
with our global need to reduce carbon emissions. In
addition, the better insulated your home, the less work the
heater needs to do, the less gas you will use and the less
impact on the environment.
By switching from electric to gas space heating you could potentially reduce your yearly running costs by up to 60%*
