Ultimate energy flexibiliy

DELTA TWINCOIL – DTC – is extremely flexible and can utilize several energy sources for maximum efficient hot water production. DELTA TWINCOIL fits most combinations of renewable energy sources (solar ≤ 12m2 / heat pump ≤ 5 kW) in combination with high temperature heat source (gas or bio-fuel boiler up to 25 kW.).The electric heating element can be used as backup heater, additional heating for added capacity, or legionella protection (controlled externally).

DELTA is our most energy-efficient water heater series, and minimizes heat loss with best-in-class
PUR insulation, vacuum panels and functional design. DELTA has been developed with a number
of smart technical solutions especially suitable for alternative energy sources such as heat pumps or
solar collectors. DELTA also features unique corrosion protection technology.
