The NIBE PUB DS series consists of three indirectly heated spiral boilers equipped with one or two copper heating coils with double dry separation (Kiwa-certified). This ensures that the boilers meet the requirements for separating heating water and tap water, meaning they can be used in installations with a heating capacity greater than 45 kW. With a capacity ranging from 160 to 500 liters, a NIBE PUB DS boiler always provides a sufficient amount of hot water. They are particularly suitable for larger homes and centrally installed collective hot water supply systems.
The NIBE PUB DS features a steel boiler tank with a corrosion-resistant copper inner lining. The efficient, high-quality insulation minimizes heat loss. For the NIBE PUB 500 DS model, the insulation is removable, allowing for easy handling and installation.
✅ Kiwa-certified – Meets the requirements for double dry separation.
✅ For larger heating systems – Required for heating systems with more than 45 kW capacity.
✅ Versatile application – Also suitable for installations with a circulation system.
