Are you aware of the Bathroom Zones and IP rating for where heated towel rails can be installed?

In New Zealand and Australia, the regulations for bathroom wet zones are designed to ensure safety and prevent damage from water. Here's a summary based on the provided search results:
1. New Zealand Building Code (NZBC) Clause E3 "Internal Moisture":
   - The design and installation of wet areas in New Zealand must comply with this clause, which aims to safeguard against illness, injury, and loss of amenity from moisture accumulation and protect adjacent units from water damage.
   - Wet areas must have adequate thermal resistance, ventilation, and space temperature.
   - Any overflow must be disposed of appropriately, and surfaces must be impervious and easy to clean.

2. Australian Regulations (AS/NZS 3000:2007):
   - Bathrooms are divided into four zones for the purpose of electrical installations, with specific requirements for each zone to prevent electrical hazards.
   - Zone 0 covers the interior area of the base of the bath or shower.
   - Zone 1 is the vertical area from the rim of the bath or shower to the ceiling, or 2.5m above the rim, whichever is lower.
   - Zone 2 is the area with a horizontal radius of 0.6m out from Zone 1, and a height of 2.25m above the floor.
   - Zone 3 is the area with a horizontal radius of 2.4m out from Zone 2, extending up to 2.5m above the floor.

These regulations are crucial for anyone designing, building, or renovating bathrooms in New Zealand and Australia, ensuring that wet areas are constructed and maintained in a way that prevents water damage and electrical hazards. Compliance with these standards is mandatory to meet building code requirements and ensure occupant safety.

What is IP Ratings ？

An IP rating, or Ingress Protection rating, is a code that indicates the level of sealing effectiveness of an electrical enclosure against intrusion from foreign bodies like dust and water. The rating consists of two digits, where the first digit represents protection against solids (e.g., dust), and the second digit represents protection against liquids (e.g., water). Higher numbers indicate a greater level of protection.

In the IP (Ingress Protection) rating system, the digits represent the level of protection against solid objects and liquids, as follows:

1. First Digit (Protection against solid objects): This indicates the degree of protection that the enclosure provides against the intrusion of solid objects. The scale ranges from 0 to 6:
   - 0: No protection against solid objects.
   - 1: Protected against solid objects of 50mm or larger.
   - 2: Protected against solid objects of 12.5mm or larger.
   - 3: Protected against solid objects of 2.5mm or larger.
   - 4: Protected against solid objects of 1mm or larger.
   - 5: Protected against limited dust ingress—partial protection against dust.
   - 6: Completely protected against dust ingress—dust-tight.

2. Second Digit (Protection against liquids): This indicates the degree of protection that the enclosure provides against harmful ingress of water. The scale ranges from 0 to 9:
   - 0: No protection against liquid ingress.
   - 1: Protected against vertically dripping water.
   - 2: Protected when tilted up to 15 degrees from vertical.
   - 3: Protected against sprays of water up to 60 degrees from the vertical.
   - 4: Protected against splashing water from all directions.
   - 5: Protected against water jets from any direction.
   - 6: Protected against powerful water jets.
   - 7: Protected against temporary immersion in water.
   - 8: Protected against long periods of immersion up to a specified pressure.
   - 9: Protected against high-temperature water jets and powerful high-pressure jets.

These digits, when combined, such as IP67 or IP54, provide a universally recognized standard for the level of protection a device offers against solid particles and water, helping users understand the suitability of the equipment for specific environments.

IP Rating shows how well a product is protected against water and dust.
Yusun heated towel rails IP rating is IP55,which means the dust proof level is 5: Dust-protect: Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
the waterproof level is 5: Water jets: Water projected in jets against the enclosure from any direction shall have no harmful effects.
As a result.IP55 heated towel rail is not recommend to be installed in all zones.
Zone 0: both 12Vand 240V towel rails . Not recommend.
Zone 1: In theory,12V towel rails can be installed in Zone 1 as long as the transformer is installed outside wet area.However,we don't recommend that, especially in shower room.
Zone 2: both 12V and 240V towel rails, very recommend.
YUSUN as a heated towel rails professional supplier, we suggest the towel rails should be better installed in Zone 2.
