Straight Heated Towel Rail 500 x 740

Product detailed description

Heated towel rails are commonly installed in residential and commercial bathrooms, utility rooms and other wet areas to provide both comfort and functionality. These systems can be integrated into central heating systems or operated independently using electrical heating coils. Installers typically deal with vertical mounting, pipe connections and ensuring correct orientation to avoid water accumulation. Compatibility with existing plumbing and electrical infrastructure is essential for seamless integration.

When selecting a heated towel rail, factors such as room size, insulation levels and system type play a critical role in performance. This model is suitable for both forced circulation and self-ventilation systems. It supports the use of heated water or other heat transfer media and is designed for installation in humid environments. The threaded connections allow for secure attachment to standard piping systems, while the reinforced construction ensures durability under normal operating conditions.

Technical parameters

Installation and connection

Installation involves securing the radiator to the wall using the included mounting kit, which contains four plastic holders, mounting consoles, vent plugs and washers. The unit must be mounted vertically due to the lack of horizontal mounting capability. Connect the inlet and outlet using 1/2 inch internal thread fittings. Ensure that the piping is correctly aligned and sealed to prevent leaks. The recommended pipe type is PEX-AL-PEX 16 x 2, which provides flexibility and durability.

Common installation mistakes include incorrect orientation, improper sealing of threaded connections and failure to install the vent plug. Always follow the manufacturer’s instructions and verify the alignment and tightness of all fittings before commissioning. The unit should be positioned to allow for even air circulation and efficient drying of towels and fabrics.

Compatibility and accessories

This model is compatible with central heating systems using heated water and can also be connected to an electrical heating coil. The recommended non-freezing mixture should be used in systems where freezing is a risk. The electric coil is not included and must be purchased separately. Additional accessories such as connection fittings and a vent plug are required for complete installation. A related product available is the Straight Heated Towel Rail 600 x 940, which offers a larger surface area for higher capacity applications.

Technical background for designers

The operating principle of this heated towel rail is based on convective heat transfer. Hot water or an electrical heating coil transfers heat to the steel structure, which then radiates warmth into the surrounding space. The 20 mm diameter heating tubes ensure high flow rates of the heat transfer medium, while the reinforced walls of the tubes and profiles contribute to long-term durability. The painted surface provides corrosion resistance, making the unit suitable for use in humid environments.

Designers should consider the thermal exponent and water volume when calculating the required number of units for a specific space. The unit is suitable for both forced circulation and self-ventilation systems and can be used as a primary or backup heat source. The orientation and positioning of the unit affect its efficiency and must be planned accordingly. The maximum operating temperature of 95°C and pressure rating of 1.0 MPa ensure safe and reliable operation under normal conditions.

Service and operation

Maintenance of the unit includes periodic inspection of the threaded connections for leaks and checking the vent plug to ensure proper air release. The unit should be drained and flushed during seasonal shutdowns to prevent sediment buildup. No specific service intervals are provided in the technical data, but regular visual inspections are recommended to identify potential issues early. The unit should be disconnected from the power supply when not in use to extend the lifespan of the electrical components.

Frequently asked questions

Can the unit be connected to an electrical heating coil from both sides?
Yes, the unit allows for installation of the electric coil from either side, providing flexibility in system design and operation.

Is it possible to mount the unit horizontally?
No, the unit is designed for vertical mounting only. Horizontal installation is not supported due to structural limitations.

What type of pipe is recommended for connecting the unit?
The recommended pipe type is PEX-AL-PEX 16 x 2, which provides good flexibility and thermal conductivity for efficient heat distribution.

Can the unit be used with a non-freezing mixture?
Yes, a non-freezing mixture is recommended for use in systems where there is a risk of freezing, ensuring continued operation in cold conditions.
