The NIBE BA-ST is a versatile, indirect heated spiral boiler designed for residential and commercial buildings. It can be used as a hot water storage unit within sustainable energy systems, for example, in combination with a heat pump or a thermal solar system as a heat source. Alternatively, the boiler can also be paired with a high-efficiency gas boiler or a pellet boiler.

The NIBE BA-ST is highly insulated and offers the option to integrate one or two electric heating elements. The series includes eight models with a capacity ranging from approximately 200 to 950 liters, available with either two separate heating coils or one double heating coil. Due to its high heat transfer capacity, the boiler can be excellently combined with both a NIBE air/water heat pump and a NIBE water/water heat pump.

The high-quality enamel coating effectively protects the boiler tank from corrosion. Optionally, the boiler can be made low-maintenance by using an electric stray current anode.

Advantages:

✅ Universal Spiral Boiler – Various sizes available to suit many hot water systems.
✅ Versatile Application Possibilities – Compatible with NIBE heat pumps, heating boilers, and solar panels.
✅ Energy-Saving – Very low heat loss due to optimal insulation.
