The difference
What each option actually means
Storage systems heat and hold water; continuous-flow systems heat on demand.
The trade-offs
Storage may suit certain supply and installation arrangements, while continuous flow avoids a storage vessel but has power or gas requirements and flow limits.
How to decide
Check simultaneous fixture demand, installation location, energy supply and total installed cost.
Before choosing
A plumber should assess suitability, condition, access and applicable requirements. Product or repair recommendations made without seeing the property are preliminary. Ask for the proposed scope, exclusions and relevant warranty details before approving the work.
