Benefits

A single unit provides up to 20.6 litres (35°C rise), 28.8 litres (25°C rise) of DHW per minute and 865 litres (50°C rise) of DHW per hour.

With the ability to cascade up to 12 units, the intelligent software will automatically rotate the lead unit after 100 hours, distributing the workload equally and increasing the longevity of the appliances.

Perfect solution for small, medium and large commercial applications.

The appliances are working with either natural gas (NG) or liquefied petroleum gas (LPG).

The water heater achieves condensing efficiency by incorporating a secondary heat exchanger. Heat within the flue gases is used to preheat the inlet water, and so recaptures energy that would otherwise be lost.

The CWi47's ability to use inlet water pre-heated by renewable heat sources supports planning and investment requirements.

Such applications can take full advantage of the cascade
controls that are part of the Greenspring offering.

These controls provide the ability to deliver up to 247 litres of hot water a minute, on demand, with no need for hot water storage accessories.
