Does the generator need a drain outlet


The only practical reason to fit an automatic drain to a steam generator is to help counter the effects of limescale. Helo generators feature incalloy or tinned copper elements and a stainless steel tank, both of which are highly resistant to limescale, therefore reducing the need for an automatic drain.

Helo generators are supplied with a manual lever valve for periodic draining. An automatic drain is optionally available for continuous use or when a water softener is included.
