When using the electric element only (ie; during summer), allowance must be made for thermal expansion within the product by having the ‘return’ radiator valve left partially open. The ‘flow’ radiator valve must be closed to prevent back flow through the system. Both valves should be opened and balanced when the central heating system is operative, (i.e. during winter).

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.
