Esprit : Flow rates
Boiler will provide DHW based on a 35C temp rise on the incoming cold water mains.
The temp of the cold mains water will vary between summer and winter.
In the colder winter months you may need to reduce the flow rate by turning down the taps to obtain a higher temperature of water.
The flow of water may be too fast to heat the water to the required temp.
| Isar Model | Flow Rate ( l / min) | This table shows the flow rates of each boiler. For eg. The Esprit 24 is capable of producing 9.6 litres per minute at a 35C temp rise from the incoming cold water. |
|---|---|---|
| Esprit 24 | 9.6 | |
| Esprit 30 | 12.0 | |
| Esprit 35 | 14.4 |
This could be checked by timing the filling of a 5 litre (1 gallon) bucket.
