Smart E Plus
Stainless steel indirect water heater with ACV’s tank-in-tank design is able to accommodate the connection of a heat pump in addition to a gas boiler.
The Smart Line E Plus cylinders incorporate all of the elements of ACV’s other hot water tanks:
The hot water tank is made of stainless steel. It constitutes the inner tank of the Tank in Tank water heater, completely immersed in the primary water of the heating circuit. The large heat exchange surface (1.5 to 2.5 times more than that of a traditional coil) enables the tank to heat a large quantity of domestic hot water in a very short time, which reduces the volume of water stored and limits energy losses.
