Dual Fuel Heated Towel Rail – Buying Guide

Stylish, practical and a great way to keep the towels toasty and your bathroom warm all year round, in this ultimate buying guide we give you the lowdown on everything you need to know about dual fuel towel rails.

What Are Dual Fuel Towel Rails?

Simply put, a dual fuel towel rail is a heated towel rail that is connected to both your central heating AND your mains electric – meaning the appliance can be heated by your boiler or by an electrical heating element.

So in winter, you can power the towel rail with the central heating – just like the rest of the house – but in summer, you can switch to electric only and have the heating element do the job of keeping your bathroom cosy and your towels warm and dry.

This makes perfect sense when you think about it.

What’s the point of firing up the heating system for the entire house when all you need is the towel rail in your bathroom to click on and keep that space warm?

This convenient heating option gives you greater control over how you use your towel radiator – simply switch it off when the central heating is on and switch it on when the heating is off.

Why Buy A Dual Fuel Towel Rail?

The idea that you can have warm and toasty towels to hand every time you step out of the shower, should be enough to persuade even the biggest spendthrift to invest in dual fuel heating.

But if you take a little more persuasion than most, perhaps the following important aspects of dual fuel towel radiators may help to bump them closer to the top of your bathroom wish list.

Flexible Dual Fuel Heating

Whether it’s the height of summer or the cold dark depths of winter, to be greeted by a warm towel from your bathroom radiator is always going to be a luxurious experience.

But when it’s 30 degrees outside, you won’t want the whole house heated up and heating your bathroom towel rail alone would involve wandering around your home and turning off each radiator individually – who has time for that?

Dual fuel towel rails give you the flexibility you need to heat your bathroom with central heating in the winter and electricity in the summer – the best of both heating worlds.

Cost Effective & Efficient

This flexibility makes dual fuel more cost effective than a centrally heated bathroom radiator or a single electric-powered towel rail. Having the option to choose which way to power the appliance based on the time of year makes a dual fuel towel rail much more energy efficient.

You can expand on this even further by combining the towel rail with an external thermostat and benefit from even more energy-saving brilliance. Set it to a timer so the towels are ready to go in the morning or the evening and, as the rest of the house isn’t being heated, you don’t have to worry about any wasted energy or money!

Why Not Buy an Electric Towel Rail?

Of course, you could opt for an electric only towel rail, but while they will work independently from your central heating, they are much less effective and efficient to use all year round.

Although they are ideal for use in the summer, as soon as the weather starts to turn, they won’t be as cost effective as a dual fuel towel rail that can be powered by your central heating.

With dual fuel, you get the best of both the electric and the plumbed power, giving you the benefits of both central heating and electric in one attractive package!

How To Buy A Dual Fuel Towel Rail

For a dedicated bathroom towel rail – that is simply there to keep your towels warm and dry – you need not go to a great deal of trouble calculating BTUs for the entire space.

However, if you do have a large family bathroom that requires your towel rail to heat the space, it might be useful to know how to calculate BTUs and why it’s important.

On the Big Bathroom Shop website, each dual fuel towel rail and radiator features extensive and important information to help you make the right choice and ensure you buy just what you need to fit your bathroom space.

We don’t expect you to go searching around our website to find the perfect heating element!

How to make your dual fuel towel rail electric

  1. Turn the inlet & outlet valves off completely – this is to ensure you isolate the radiator from the rest of the central heating system.
  2. Loosen either the bleed valve or the return valve – making sure to do this gently and only a little – this is important to prevent too much pressure building inside the towel rail.
  3. When required, you can then safely switch on the power supply to your heating element.


How to switch your dual fuel towel rail back to plumbed

  1. Switch the off the heating element.
  2. Retighten the bleed or return valve, being careful not to overtighten and do any damage.
  3. Return the inlet and outlet valves their fully open position.
