Dorchester DR-RS

Room sealed gas fired water heater

  • Room sealed
  • Fully automatic ignition
  • Control thermostat range 40 to 70c
  • Multi-tube heat exchanger
  • Magnesium sacrificial anodes
  • Volt free contacts - for lockout and normal run

The Dorchester DR-RS range is designed to operate as a room sealed system, making it particularly suited to applications where a conventional flue is impractical, or where the heater is be located closer to point of use. Units are available with either vertical or horizontal flue arrangements using twin duct or concentric flue systems.

Consisting of 5 models with continuous outputs from 507 to 1960 litres/hour, the DR-RS is based on a 44c temperature rise. Storage capacities range from 265 to 324 litres. Two or more water heaters can be installed where there is demand for larger loads.

The DR-RS is fitted with an atmospheric burner with fully automatic ignition, and is suitable for firing natural gas or LPG. Volt free contacts are fitted as standard, and are compatible with building management systems (BMS) for monitoring the operation and status of the unit.

Other Dorchester models available include the Dorchester DR-PF power flame range, the Dorchester DR-LA / DR-LP multi tube range, the  Dorchester DR-SA  / DR-SE single tube range.
