The NIBE PUB DS series consists of three indirectly heated spiral water heaters, each equipped with one or two copper heating spirals with dry double separation (with Kiwa certification). This ensures that the boilers meet the requirements for separation between 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 guarantees an adequate amount of hot water. NIBE PUB DS boilers are particularly suitable for larger homes and centrally installed collective hot water supply systems. The NIBE PUB DS is equipped with 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, the insulation is removable, making the boiler easy to handle and install.
WITH KIWA CERTIFICATION
The boilers are equipped with Kiwa certification for dry double separation.
FOR LARGER HEATING INSTALLATIONS
For heating systems with a capacity > 45 kW and connection to the heating system, Kiwa certification is required.
WIDELY APPLICABLE
Also suitable for installations with a ring system.
