DELTA COIL – DC

DELTA series is an award-winning hot water cylinder recognised as the most efficient product available. It incorporates unique Vacuum Insulation Panels and is the only full range of ErP A-rated cylinders available from 150 – 300 L. DELTA series can save enough energy to pay for the entire cylinder over its lifetime.

DELTA COIL— DC is elegant and functional in its design, and is compatible with all boilers

The DC units can be controlled either via its own thermostat or using a thermistor probe. DELTA uses a high performance fully flooded design, with separate expansion vessel, and an ultra-grade INCOTEC immersion heater as back-up above the heating coil. This provides the cylinder with maximum operational safety. A complete set of inlet control valves comes as standard. DELTA COIL is also supplied with a digital thermostat compatible with both S & Y plan systems which displays the water temperature.
