DELTA GEO series is the most efficient heat pump cylinder available, incorporating our unique award-winning Vacuum Insulation Panels, and is the only range of ErP Aated heat pump cylinders available from 200 – 300 L.

DELTA series can save enough energy to pay for the entire cylinder over its lifetime.
DELTA GEOCOIL— DGC is ideal for domestic hot water production from heat pumps up to r 15 kW . DGC can also be fitted with gas or oil boilers for super-fast heat up times.

The DGC units can be controlled either via its own digital thermostat or using thermistor probe(s). Compatible with S & Y plan systems.
