How to buy
Order your radiator in six easy steps
1. Confirm your heat output requirements;
Please use our Heat Output Calculator for a quick guide, however we recommend you check outputs with your installer before making a purchase. It is essential that you know how much heat you will need as this will determine the size of your radiators.
2. Choose your design;
Our range has everything from traditional cast iron to mild steel designer radiators (even a range of environmentally friendly aluminium radiators), with a choice of sizes, colours and outputs to suit every interior scheme.
3. Select a size that meets your heat output requirement;
Outputs are shown in the product information section of each product page and will help you and your installer to find the best match for your needs. All outputs are shown at Delta ΔT 50°C in both British Thermal Units (BTU’s) and Watts.
Our Product Range
All our radiators are produced and outputs measured in accordance with European standard EN442.
Radiators are supplied with BOE connections as standard unless stated otherwise.
Due to the excessively corrosive nature of chlorine we do not recommend that radiators and towel rails are placed in swimming pool environments. In addition radiators should not be located in areas that have long term exposure to high levels of moisture.
When commissioning any radiator (including aluminium) on an indirect/closed system we recommend using a suitable mixed metal inhibitor in suitable quantities to protect against scale and corrosion, please be sure to consult your installer.
Electric / Dual Fuel
The majority of our towel rails can be converted to work as dual fuel models. An electric element and T-Piece is needed to adapt the towel rail; your installer will need to be aware if you wish to do this in order to adjust pipe centres accordingly. See our accessories range for all our elements and T-Pieces. If a towel rail is suitable for dual fuel it will be noted in the product overview section.
We endeavour to ensure all pipe centres are correct, however manufacturing tolerances must be considered; therefore we strongly recommend that pipe work is not altered or adjusted until your new radiator or towel rail is delivered. Radiators Direct will not accept any responsibility for claims resulting from incorrect pipe centres.
4. Select your finish/colour;
With up to 24 colours and 6 special finishes, why not match your colour scheme or introduce an accent colour to create a striking feature. For help choosing your finish please review our colour chart.
5. Select a valve;
To complete the look, choose from our wide selection of both TRV and Manual valves and add accessories that complement your radiator. We recommend using TRV valves in all living and bedrooms to maximise the efficiency of your radiators. Please remember to take into account the valves when working out the overall width of the radiator in relation to your required pipe centres.
6. Add to basket;
Add your selected, radiator, valve and accessories to your basket and complete the checkout stages for order completion.
Please note that many of our factories close for 2 - 4 weeks during the holiday period of July/August and December. This may extend the delivery period quoted here depending on stock availability and demand. We will confirm the scheduled delivery date with you prior to despatching your order. Unfortunately delivery to Scotland / Offshore Islands may take longer due to the distance involved. Deliveries will be made to the nearest hard standing area. A nominal £5 charge for postage and packing will be applied to any orders under £50 in value.
Deliveries to non-mainland UK addresses, Direct delivery (to site or domestic addresses), or delivery requests outside our standard delivery times (e.g. Next Day) may have delivery charges added, such charges must be agreed prior to shipment and will be at the discretion of Radiators Direct taking into account the delivery address, value of the order and requested delivery date of the order.
All radiators and towel rails featured on this website are suitable for indirect/closed systems that comply with 'BS5449, section 1 forced circulation hot water systems'.
Systems running with low pressures (under 1 Bar) or microbore pipework may experience flow and heating issues if not accounted for in the system design which could result in radiators not heating fully or noisy pipework.
Direct heating systems use your hot water supply to heat a radiator; usually this will occur in a bathroom. if you have any radiator or towel rails linked to a direct system they should be made from either stainless steel or brass to avoid rusting and contaminating the hot water supply.
Powder coat finishes and painted cast iron
It should be noted that due to the production process colours can vary by +/- 5-10% from samples provided and between radiators ordered in the same colour at different times. All painted cast iron radiators will be checked and tested prior to despatch. Care must be taken when handling any radiators on site to avoid damaging the product or finish. Cast iron radiators may be supplied with a small bottle of touch up paint in case of damage to the finish during installation, however it should be noted that this may vary slightly from the standard powder coat finish. As a result of the casting process, cast iron radiators have a rough surface finish with small imperfections which will show after the painting process.
