It is the evolution of the classic autoclave pump, but with an electronic brain and Bluetooth .
Want the perfect shower at home and need to install the pump inside your apartment? Choose SCALA2 .
Need to water your garden, draw water from a well, or install a pump in your garage where the gentle hum won't disturb you? Save money and choose SCALA1 .
Yes, both are self-priming. They can draw water from tanks or wells up to 8 meters deep in less than 5 minutes. Just remember to fill the pump body with water (using the appropriate cap) before using it for the first time.
Generally, no. SCALA boilers have a small built-in expansion tank to handle small leaks (drips). However, if you have leaks in the system or want to reduce frequent starts, you can install a small external 8-24 liter tank on the flow line.
Yes, both are equipped with dry-running protection. If the tank empties or the mains water supply shuts off, the pump stops and automatically tries to restart after a while, preventing the motor from burning out.
