Ultimate energy flexibiliy

DELTA TWINCOIL - DTC - is extremely flexible and can use multiple energy sources to produce hot water with maximum efficiency. The DELTA TWINCOIL can be adapted to most combinations of renewable energy sources (solar ≤ 12m2 / heat pump ≤ 5 kW) with a high temperature heat source (gas or bio-fired boiler up to 25 kW.) A high temperature heat source can also be connected to the lower heat exchanger, while the upper heat exchanger can deliver heat to a small heating circuit for the dwelling. The electric heating element can be used as a back-up heater, as auxiliary heating to increase capacity or as a legionella protection (with external control). The mixing valve can be easily retrofitted as an option if required.

DELTA is our most energy efficient water heater range, minimising heat loss through enhanced insulation, vacuum panels and functional design. DELTA has been developed with a number of intelligent technical solutions, particularly suitable for alternative energy sources such as heat pumps, solar collectors or bio-hot water heaters. DELTA is also equipped with unique corrosion protection and can withstand 3× higher salinity than other water heaters.

WHY DELTA TWINCOIL?
• Save approx. 650 kWh / year compared to mineral wool-insulated boilers (200 L)
• Two integrated heat exchangers for maximum flexibility
• Unique corrossion resistance features
