Dorchester DR-FC Evo Condensing Water Heater  

 

Hamworthy offer the Dorchester DR-FC Evo range of condensing direct gas fired water heaters in response to the demand for increased efficiencies in domestic hot water (DHW) appliances for modern commercial applications.

Featuring modulating burners and condensing operation, the Dorchester DR-FC Evo water heaters provide a high efficiency DHW solution which can be sized to suit many applications; and with a wide range of flueing options supported: room sealed, open flue, flue schemes B23, C13, C33 and C53, and very long flue runs up to 100m, these water heaters can be sited almost anywhere in a building.

There are 7 models in the Dorchester DR-FC Evo range from 600 to 2400 litres/hour continuous output at 44°C temperature rise, and storage capacities from 227 to 504 litres. For large loads, multiple water heaters can be installed, and for a large hot water buffer, Hamworthy can offer a direct fired unit with additional storage tanks.
