Heaters in wetrooms

When installing heaters in bathrooms and other wetrooms, there are certain rules that have to be observed.  To follow is a simple overview of what you have to bear in mind before installing heaters in wetrooms.

Electrical enclosure

Electrical enclosure or IP rating (Ingress Protection) are standards used to specify the ability of an appliance to tolerate water, dust and other foreign objects. Certification rating has a standard format: IPXX, where XX stands for two numbers, e.g. IP20 and IP24.

For example, let’s look at the ’24’ in IP24: 2 and 4.

The first figure indicates the resistance to solid foreign objects (dust, flies etc.) whilst the second indicates resistance to water. 

The three wetroom zones

Wetrooms are divided into three different zones, based on proximity to humidity and water. That means that different requirements apply to radiator placed in the different zones. Electrical enclosure or IP ratings for the different zones are presented below.

Zone 0

The inner part of a bathtub or shower.

Zone 1

From the upper level of area 0, to 225 cm above floor level. If you have a bathtub for example, zone 1 is counted from the edge of the tub.

Zone 2

60 cm away from zones 0 and 1, i.e. on the floor surface and up the wall. 225cm high.

Zone 3

240 cm away from zones 0 and 1, i.e. on the floor surface and up the wall. 225cm high.

Zone 0:         Minimum IP X7

Zone 1/2:     Minimum IP X4

Zone 3:         Minimum IP X10

Most of our heaters are IP24 approved and can be mounted in zone 2 and above. Remember that radiators must have fixed connection and must be installed by an authorised electrical installer in all wet- and bathrooms.
