Dorchester DR-CC compact condensing water heater
Fully automatic, simple to operate condensing direct fired water heater for domestic hot water.
9 models available with continuous outputs (@44°C ∆T) of 228, 233, 374, 461, 465, 602, 608 & 614 l/h.
Product information
- Low power outputs 11-29kW and storage capacities of 162-384 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.
- Load profiles of XL or XXL and an A rating ensure all models in the range 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
- Available for next day delivery (dependent on stock availability, charges apply, order cut-off 12pm).
