Steel Rails - Must be installed in accordance with BS7593 where a corrosion inhibitor is used
Brass Rails - Caution where water softener is installed, as this could cause dezincification
(material is attacked ie. zinc eaten away by aggressive water).
Brass towel rails are manufactured using dezincification resistant brass, however it should be understood that the term ‘resistant’ does not entirely preclude the possibility of dezincification occurring. If you intend to install the product on an open (DHW) circuit, make reference to your local water authority to ensure dezincification has not previously occurred. Towel rails manufactured from brass tubing should not be installed on an open circuit if a water softener is present. Water analysis to determine the likelihood of dezincification is available at cost.
Models suitable for indirect (closed) circuits only cannot be installed on an open circuit due to the item containing ferrous (steel) parts. Product compatibility is the responsibility of the installer.
HEATING ONLY (HO) - Suitable for ALL circuits
HEATING ONLY (HO) - Suitable for indirect (closed) circuits
ELECTRIC ONLY (EO)
A completely independent unit requiring only a fused spur electric connection in close proximity. Standard format for electric towel rails is fluid filled. Thermal transfer fluid is heated by an electric element located at the bottom of the towel rail. The element is a sealed cartridge and therefore can be easily changed in case of failure.
HEATING & ELECTRIC (HE)
Also known as dual fuel or dual energy. Connected to a central heating circuit and including an electrical element which allows for operation in summer months when the central heating is NOT in use.
