OSO DELTA TWINCOIL DTC

Water heater with ultimate energy flexibiliy

Water heater DELTA TWINCOIL – DTC – is extremely flexible and can utilize one or more energy sources for maximum efficient hot water production. DELTA TWINCOIL fits most combinations of renewable energy sources (solar ≤ 12 m² / heat pump ≤ 5kW) in combination with high temperature heat source (gas or bio boiler up to 25 kW.) Alternatively, district heating or high temperature heat source can be connected to the lower heat exchanger, while the upper can emit heat to a small heating circuit for the home. Electric heating element can be used as backup, additional heating, summer operation or legionella protection (controlled externally). Mixing valve can easily be retrofitted as an option if required.

Water heater DELTA is our most energy-efficient boiler series, and minimizes heat loss with increased insulation, the use of 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, solar collectors or bio boilers. DELTA also has unique corrosion protection and can withstand 3 × higher salt content than other boilers.

WHY CHOOSE DELTA TWINCOIL?

  • Save approx. 650 kWh / year in relation to good, insulated water heaters (200 L)
  • Two integrated heat exchangers for maximum flexibility
  • 3 x higher corrosion resistance than others

Advantages

MORE HOT WATER
Substantially higher temperature (70°C+), highly efficient mixing valve (no scolding), minimal heat loss and optimal design features gives up to 20 % more hot water and class leading capacity.

PRO INSULATION
The use of NANOPUR™ with insulation values far surpassing Pentane, often in combination with VACUUM panels, ensures minimum heat loss and class leading energy efficiency.

STRONGER
EVERLAST™ titanium alloyed stainless steel in combination with OSO’s unique ULTRAWELD™ system and state-of-the-art passivation process equals class leading corrosion resistance.

LIGHTER
EVERLAST™ titanium alloyed, high tensile strength, stainless steel equals lower weight and efficient use of resources. OSO products are more than 40 % lighter than enameled products.

BUILT TO LAST
INCOTEC™ el. immersion heaters with ultra high-grade Incoloy 825 stainless, DZR brass, zinc-free soldering and carefully calculated surface loads results in maximum durability in hard water.
