Dorchester DR-CC compact condensing water heater
Fully automatic, simple to operate condensing direct fired water heater for domestic hot water.
2 models available with continuous outputs (@44°C ∆T) of 228 and 233 l/h.
Product information
Compact water heaters with storage capacities of 162 or 202 litres.
Compact, standalone water heating unit for safe and clean domestic hot water generation.
No clearances required at the rear and minimal clearances at top and sides allow easy siting in any plant room.
Reduces energy use and running costs by maximising condensing water heater performance.
Meets the strict standards for efficiencies and NOx emissions (under 37 mg/kWh) in new buildings.
An XL load profile and an A rating ensure both models are fully compliant with the ErP (Energy-related Products Directive) regulations.
Closely matches hot water demand, reducing wastage of energy.
Electronic Anode fitted as standard to protect against corrosion.
No top-to-bottom re-circulation kit required due to the heat exchanger coil positioned in the centre of the unit for even heat distribution and reduced likelihood of stratification.
Down firing pre-mix modulating burner reduces the risk of scale build up impacting on the heat transfer.
Natural gas and LPG water heater options.
All components accessible under front cover for ease of service and maintenance.
Flexible flue options (see optional extras tab and brochure for details).
Full project assistance available from our dedicated hot water expert to help with hot water sizing and selection of equipment to match the application.
Extensive back up and support from our team of experienced engineers across the UK.
Long-term commitment to spare parts.
BIM objects available to assist in design and management
