advice on which valves to purchase for piped installation (central heating)

• This heated towel rail is not supplied with valves, as we have such a vast selection of styles & colours to choose from, we do not include them (like some other retailers) as we cannot make this choice on your behalf.
• However, we make choosing the correct valves very easy for you. With our years of experience, we know once homeowners have chosen their rail, the valve selection process can be a little daunting — and even the plumber won't make the best choice for you in terms of aesthetics. You need to do this yourself, as remember you are left looking at the installation once the plumber has gone — often we have spoken to homeowners who have been disappointed with how the poor valve choice or absence of pipes & covers have let down the look — don't let this be you.
• On the right-hand side of this page we have pre-filtered our vast selection of valves to show you only the optimal valves for this specific model — easy — you'll see two sections of valves:
  • 1. matching/complementary colour valve & pipe sets — these could be an exact match (as they are painted using the same paint as the radiators) or the closest complementary match. These valves come complete with pipes and wall covers which will conceal the standard copper or plastic pipes of your central heating system for a much more professional-looking finish.
  • 2. standard valve & pipe sets — these are more economical standard valves which are not painted using the same paints as the radiators, so will never match. We show the closest colour only. These are not sold as sets; if you'd like pipes/covers, these need to be purchased separately.
• Which orientation of valves do I need: 3-Axis (corner), straight or angled?
  • 1. Your central heating pipework comes through the wall — typically most modern pipework comes through the wall now and for this you'll need 3-axis corner valves. If your pipework is not yet in - our best advice is to ask your plumber to bring this through the wall.
  • 2. Your central heating pipework comes through the floor — this is less common and only found in more period properties - for this you'll need straight valves - as these valves are less common we don't offer these as full sets; you'll need to view the valves section for all available straight options.
  • Note: Finally, angled valves are not a good match for any heated towel rail (as the valve head will stick forward at the bottom), so we do not show any angled valves on the product pages for heated towel rails.
• Additionally, we have created a thorough and detailed technical guide on radiator valves, giving even more information and tips.

what is dual fuel and advice on what accessories to purchase if installing as dual fuel

• Dual Fuel means this towel rail can run on two energy supplies — central heating in the winter, and electric in the summer when the central heating system is typically off, but you can still run this towel rail on its own... for fluffy warm towels after a shower or to quickly dry clothes on it.
• Note: This specific model (with 50mm central connections) is not available as electric — hence will not work as dual fuel. If you would like a dual fuel towel rail you'll need to look for an alternative model within this range.
• Additionally, we have created a thorough and detailed technical guide on dual fuel towel rails, giving even more information and tips if you decide to go for a standard setup with a T-piece.

• Fully built and tested to EN442 standards and UKCA certified.
• Heat outputs are independently verified by an external testing house to ensure accuracy.
