Adding to @PhilT ’s advice (I altered the heading to better reflect your request):
There are a number of topics that cover the subject you have asked about. Some of the topics will be a few years old but the principles will remain fairly constant.
Some are about replacing gas systems, some are specific about the brands. In large part though most will have something that will add some value to answering your question.
Searching on “hot water” and/or “solar hot water” should give you some good hits.

Gas ducted heating (big winter bills)

Just replace with another standalone gas, solar or electric hot water system
Switch hot water to electric and replace the gas ducted heating with a ducted electric split system
Heat pump?
Other?
Has anyone gone through a similar situation?
Cheers

My electric storage hot water system will need to be replaced. I do not have solar panels and I am looking for a heat pump system. I was thinking about 300 l (in case I have visitors). Meanwhile I also found that there seem to be lot of problems. Should I just get another storage hot water system and save myself all the trouble of changing to something new???
Anyone has any thoughts on evacuated tubes or Solahart Powerstore Hot Water System…
We have solar panels and winters very cool /foggy /icy days. No issues with solar hot water in summer of course.
Would appreciate Choice community experiences.
