Nesta Plus
High Efficiency Condensing Boilers
This class leading design of the Nesta Plus with large volume primary water ensures maximum heat extraction. These features allow a large increase in power with minimal increase in the boiler footprint, the perfect solution when plantroom space is at a premium. The high volume of heating water ensures boiler stability and maximum heat extraction, making the Nesta Plus the perfect solution for any application with a high output requirement but limited plantroom space.
