All BIG models have industry standard low water pressure startup on par with European models, except the B3315 ip.
The highest capacity models are the 18 Litres models available in standing pilot, ionized, and ionized forced flue. Note that the 18 litre models other than the forced flue version have specific chimney requirements and care should be taken during installation.
The latest range of BIG water heaters are the Ionized models, the forced flue models and the fourth generation (4xxx) range.
Each model is suggested and appropriate for specific conditions, and there is no “best” model. Customers should choose the models based on their needs, also keeping in mind the installation conditions.
