Direct answer
Electric hot-water systems include storage and instantaneous designs. Compare capacity, tariff, recovery time, location and compatibility with household solar—not just the purchase price.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Storage size and peak demand | Read the unit rating and model |
| Continuous tariff or controlled load | Check household usage pattern |
| Available electrical capacity | Confirm electrical and plumbing scope |
| Indoor or outdoor installation | Compare standing losses and recovery |
