EnergyPro™ cylinders for boiler systems

Nu-Heat's EnergyPro™ indirect unvented cylinders work with a gas or boiler as the primary heat source. An immersion heater is factory-fitted to provide short-term, occasional backup for the water heating.

Cylinders in Nu-Heat’s EnergyPro™ range meet all relevant UK and European standards and are covered by a 25-year warranty.
