ie: The Rinnai B26 generally works out to be free installation for a new gas hot water system:

I had the Rinnai 26 installed by https://www.productreview.com.au/p/australian-hot-water.htm, in the North Shore
They did a fantastic job, all done in 1 day, cleaned up everything, no additional charges to what I agreed, and it works very well since then.
At the time they said their model would only have a $300 cashback, turned out they were wrong, and I got $500 refunded by Rinnai.
With cash back it was about $800.
On a note, it takes about 15-20 seconds till the hot water arrives to the shower head.
