🔵 What is a gas storage hot water system?
- Stores hot water in a tank
- Heats and keeps water ready to use
- Can run out during high demand
- Usually higher standby energy loss
Good for:
- families with consistent usage
- homes already set up for tanks
🟢 What is a gas instant (continuous flow) system?
- Heats water only when you turn the tap on
- No storage tank
- Endless hot water (if sized correctly)
- More energy efficient in many cases
Good for:
- smaller homes
- people wanting efficiency
- limited space homes
⚖️ Gas storage vs gas instant – key differences
- Storage = ready hot water, but can run out
- Instant = endless hot water, but depends on flow rate
- Storage = bigger unit
- Instant = compact wall-mounted unit
- Storage = more standby loss
- Instant = heats on demand
🧠 Which one is better?
It depends on:
- number of people in the home
- number of bathrooms
- available space
- existing plumbing setup
There is no “one size fits all” system.
