An unfortunate circumstance is that I have lived in rented properties most of my life, moved in an out of house I think in total about 15 times.
What I have noticed though is that gas instant hot water was primarily cheaper to run than any system, there are some obvious negatives to it but overall not bad.
One place that proved the most efficient was a house that I owned some time ago, installed a solar hot water system with a wood fire stove with inbuilt booster (semi rural place) quite good.
Electricity though too expensive, whether it it is in relation to power consumption electricity has a much higher hidden cost and that is the damaging effect of coal power station. I don't think we can ignore that it is quite possible the government scientific advisor are correct and need keep and open mind on that policy.
It is not advisable to trust any tradie opinion as especially electricians as they will oppose any changes that will affect their bottom line. I am also a tradie so i can say this without reservation.
I am all for self sufficiency, I would love the opportuinity to live in the country living off the land but we live in a real western world as it is and we need to further understand the implications of what we are doing to the planet if the evidence is there.
One legislation that has a great impact to my business and the community I deal with is, the removal of incandecent globe and replacing them with CFL. As deaf people need flashing light lights to indicate sounds. the removal of these will prohbit this due to long switching times. But they have become accustomed to the idea early and are making changes fairly easily. The same could be said for hot water systems.
