The information here is general
The guidance on this site describes how hot water systems generally behave and what usually matters when choosing between them. It is written to help you ask better questions, not to diagnose your system from a distance.
Every property is different. Existing connections, available space, roof orientation, household demand and the condition of what is already installed all change the right answer. Nothing on this site should be treated as advice specific to your property until we have actually looked at it.
Do not attempt work on gas, electrical or pressurised components yourself. That work is licensed in Queensland for good reasons.
