NEXT DAY DELIVERY (ORDER BEFORE 2.30PM)

Henrad Radiator Testing and Operating Pressures
All Henrad Models are high pressure tested to withstand 10.5 (152.3 psi), to perform at a maximum working pressure of 8 bar (116psi) at a maximum temperature of 95°C. Higher working pressures are available by request.

Henrad Radiator Connections
Each Henrad Radiator has 4 x 1/2 inch connections as standard. There is also a 3/4 inch valve adaptor available, which provides 3/4 inch connector option to the valve without reducing performance.

Henrad Radiator Applications
Henrad radiators are suitable for two pipe installation. For single pipe applications, it is advisable to use diversion tees in the pipework, as this will assist in obtaining design performance from the radiators. Although Henrad radiators are suitable for Microbore pipework, the back tappings make it unsuitable for twin entry valves.

Henrad Radiator Installation
Everything requiredfor installation can be found within the robust packaging.
Brackets are of a strong design, with open top and deep slots, which facilitate easy and secure installation. Plastic inserts seat the radiator precisely on the bracket minimising expansion and contraction noise.
The neat nickel-plated plug and vent provide a watertight joint, whilst complementing the superior finish.
To facilitate easy one off replacement nickel-plated brass extension pieces are also available , complete with sealing washer, in 20mm, 30mm, 40mm options.
Recommended height from the floor to the base of the radiator is 150mm minimum. This allows adequate airflow when the radiator is placed on the bracket.

Caution 
When designing for domestic systems we recommend that the Henrad Radiators be used only in heating systems complying with British Standard Code of Practice for Central Heating for Domestic Premises BS 5449 Part 1.
Single feed, indirect cylinders are not recommended as should interchange of water occur, fresh aerated water would enter the heating system, resulting in corrosion.

Henrad Radiator Water Treatment
On completion of the installation the system should be properly flushed and filled in accordance with the British Standard Code of Practice for the Treatment of Water in Domestic Hot Water Central Heating Systems BS 7593.
This will remove flux residues and installation debris, which might promote corrosion and damage within the system.
If it is decided to apply a corrosion inhibitor to maximise the working life of the system, it should be applied in accordance with the manufacturers instructions and should be suitable for the particular metals within the system.
