- Reduced storage volumes and standing losses
- Rapid recovery periods
- Reduction in plantroom space requirements
- Units designed for hourly output of up to four times the nominal storage capacity
- Peak loads in excess of the hourly output rate can be achieved without increasing boiler output requirements
- The in-built heat exchanger is designed to heat water from 10°C to 65°C in a single pass by utilising the pumped circulation, regulated by a variable orifice double regulating valve
- Full active storage within the calorifier reduces the risk of growth of the Legionella bacteria
- The Evolution is a high output exchanger suited to cyclical demand patterns. It is able to operate at high primary temperatures and pressures without the need for additional reducing stations or pressure breakers.
- The Evolution is available for both vented and unvented applications.
