Cylinders

EnergyPro® Solar cylinders

Nu-Heat's EnergyPro® Solar indirect unvented cylinders work with a boiler or heat pump as the primary heat source and feature a second coil linked to a solar collector system. An immersion heater is factory-fitted to provide short-term, occasional backup for the water heating.

Integrated thinking

Nu-Heat supplies the EnergyPro® Solar range of solar hot water cylinders, which meet all relevant UK and European standards and have a 25-year warranty. There are models that integrate with a boiler or heat pump and we will always advise on the size that best suits the project requirements for both heating and domestic hot water.
