What splash-protection do I need in a bathroom?
Electrical Safety in bathrooms divides into four zones.
In zone ‘0’ which defines being within in the sink bowl, bath tub or shower cubicle any electrical appliance must be direct current and low voltage.
Zone 1 is any zone above a bath or sink or around an unenclosed shower that is prone to splashing. Any electric appliance operated in this zone must have a protection rating of IP44 or higher.
Zone 2 is a 60cm safe zone outside zone 1 to which the same IP44 minimum rule also applies.
“No Zone” is any other area in which theoretically no ingress protection need be applied.
All electrical appliances in a bathroom should be protected with a 30 ma RCD (Residual Circuit Device).
This means that any Herschel panel heater may be installed within zones 1 or 2 (or “no zone”). If you are seeking to install an Advantage or Aspect space heater, please seek the advice of your Herschel Installer, since IP ratings vary.
