Step 2 - Choose your Finish:

Our stunning range of cast iron radiators are available in a multitude of finishes to suit your interior design. We have broken your options down into 5 main categories:

Option 1 - Painted

For an authentic, historical finish here at NWT we use only the highest quality paint supplied by Farrow and Ball. We have hand picked the most popular colour ranges for you to choose from that will seamlessly blend and compliment your surroundings. As standard we use an oil base paint mix which is expertly applied by our highly skilled staff.

Option 2 - Metallic

Our range of metallic finishes are already proving extremely popular and truly set your radiator installation apart. The available metallic paints ooze luxury and warmth and can be matched to compliment other metallic objects within your roomset. We do NOT charge a premium for metallic paint finishes making them an affordable, luxury option with sample swatches available on request.

Option 3 - Antiqued

To complete the period look of your NWT Cast Iron Radiator our highly skilled team have perfected the art of the antique paint effect. Simply choose your historical or metallic paint as a base colour with an antique finish and we will transform your cast iron radiator into an authentic piece of historical art. This service is particularly effective on the decorative radiator styles where the raised etched designs can be accentuated.

Option 4 - Highlights

For a truly dramatic and atmospheric piece of design our highly skilled team can transform your cast iron radiator design through our highlighted paint effects. Simply choose your historical or metallic paint as a base colour and then choose one of our 3 stunning highlight effects (Copper, Pewter or Gold) The contrasting highlights emphasize every intricate detail of the cast radiator design creating a beautiful one-off piece.

Option 5 - Polished OR Coloured Lacquer

Our hand polished finishes are available in 3 unique designs (Industrial, Burnished or High Polish) This is a highly specialised process involving each section of your cast iron radiator being hand finished to your chosen design.

Step 4 - Please read our Technical Info and Terms & Conditions:

Customer Service:

Choosing cast iron radiators for your heating system need not be a daunting project. We are on hand via telephone 01492 573738 or email info@nwtdirect.co.uk for all enquiries. We take you step by step through the extensive choices you have in radiator and fittings style and the technical aspects of installation. We can help you with the BTU calculations required for each room and the size of radiator you require for each space. A specification sheet is provided, upon request, for all pipe work measurements required for installation.

All dimensions provided are subject to manufacturers tolerances and as each cast iron radiator is custom built there might be slight variances in the sizes listed. In certain circumstances due to the weight, size of radiator required, space availability or stairway entrance, a cast iron radiator can be delivered in 2 or more parts with a joining tool for construction upon site, this can be discussed with your requirements.

Custom Built and Pressure Tested Ready for Installation:

Each order is custom built to specification and delivered ready for installation. We recommend radiators be on site before your pipe work is completed. Upon request a specification sheet is provided with all measurements required for installation of necessary pipe work. Most cast iron radiators are supplied with 1/2 inch connections as standard (We have the option of 3/4 inch on enquiry)
Valve connections are bottom opposite end as standard, top end connections are available upon request.

All radiators are pressure tested to 6 Bar but recommend a working pressure of no more than 2.5 Bar.


Outputs are listed in Watts and BTU (British Thermal Units) with a Delta (Æ)t of 50°C. Watts x 3.412=BTU/h. We quote our heat output efficiency at Æt of 50°C as this is the average working temperature required. We provide our 10 Year Manufacturer Guarantee for extra peace of mind. 

Water Treatment:

Cast iron radiators are for use on closed, indirect central heating systems (sealed systems) only, they are not suitable for installation on open hot water system circuits. Upon completion of the installation the entire system must be thoroughly cleaned and flushed to remove debris and flux residues etc. If a chemical cleanser is used it must be thoroughly flushed from the system. Following this procedure the system must be closed with a good eminence water treatment to prevent corrosion. We recommend the use of Fernox water treatments. System design, flushing and dosing must be in accordance with BS 5449, 1990, BS EN 12828: 2003 and BS 7593.

We strongly discourage the use of a water softener on the heating system as this treatment can cause problems with the seals. It is important to note that failure to observe these requirements will render the guarantee on the products void. Corrosion inhibitor must be used in accordance with the manufacturer's instructions and  recommendations and should take into account the particular metals within the system.


All our cast iron radiators are delivered via pallet for additional security during transportation. We provide a maximum 7 working day delivery on Standard or Metallic Paint Finishes and a maximum 7-10 working day for antiqued, highlighted or fully polished finishes.


We offer a 14 days return period on our cast iron radiators from date of delivery for a change of mind on your order. You will be responsible for the return delivery of the product back to us in perfect re-sellable condition and as this is a custom built product you will incur a 50% restocking charge against your order total.
