Appendix 5: Gas boosted solar
In New Zealand, solar systems will need boosting unless you are willing to run out of hot
water. A gas boosted system is best because it only works when you need hot water that
your solar system can't supply.
How a gas boosted system works
1. The sun's rays heat water in the solar panels for free.
2. Hot water from the panels is stored in the tank.
3. If the water is too cold, the Rinnai Infinity gas booster heats the water on demand as it travels from the tank to
your tap.

Rinnai Infinity models can be easily plumbed to provide additional heat to a solar hot water system when they are
too cold. The size of the Rinnai Infinity depends on the number of bathrooms the house has, i.e. select the Rinnai
Infinity model as if solar hot water was not available.
