Delta Twincoil

Delta Twincoil Series cylinders are efficient solar thermal hot water cylinders which uitilize unique vacuum panel insulation. They are available from 200–300 L and are Energy-related Products Directive (ErP) B-rated. Can provide up to 60% of annual domestic hot water requirements from solar collectors.

The cylinders use a high performance fully flooded design, with separate expansion vessel and an ultra-grade Incotec immersion heater as booster (or back-up) between the heating coils. A complete set of inlet control valves are supplied as standard. A unit can be controlled either via its own digital thermostat or using thermistor probe(s). They are compatible with both S and Y plan systems, display the water temperature and offer holiday and anti-legionella modes.
