If floor heating is to be installed in a bathroom, the following is important:

• The thermostat as well as isolator or plug must be positioned at least 600 mm away from bath-tub or shower-pan (Zone 3).

• The system must be properly earthed, and all metal objects in the bathroom like taps etc. must be interconnected to that same earth (equipotential bonding).

• The system must be connected trough an Earth Leakage Circuit breaker (ELCB).
  

• Although legal, the heating should preferably not be installed under the bathtub or shower pan.

• The heating element must have an earth sheath (all Klimax heating elements do).

• The cold tails must be screened, double insulated or run in a conduit.
