The AlphaStat-Plus controller can control all types of hot water booster applications, including thermo-siphon solar, wetback or domestic hot water electric elements. With AlphaStat-Plus, you won't have to think about turning your hot water element off to save power and then remembering to turn it back on again before your shower goes cold! Your AlphaStat-Plus smoothly and efficiently takes the hassle out of maximising your power savings. It even monitors the water to make sure it is safe from legionella infection.
