Heated Towel Rails: Choosing Between Electric and Central Heating

A heated towel rail is one of those bathroom additions that, once you have one, you'll wonder how you ever lived without it. Warm, dry towels after every shower is a simple pleasure — but choosing between an electric and a central heating (plumbed) towel rail isn't always straightforward.

Central Heating Towel Rails

These connect to your existing central heating system, just like a standard radiator. They fill with hot water from the boiler and heat up when the heating is on.

Pros:

• Lower running costs — uses your existing boiler
• No additional electrical circuit required
• Gets very hot — effective bathroom heating in winter

Cons:

• Only works when the heating is on — No warm towels in summer unless you run the entire central heating system
• Requires plumbing connection to the heating circuit
• If the boiler breaks down, you lose the towel rail too
• Can't be independently controlled — it heats whenever the central heating runs

Electric Towel Rails

These run independently on their own electrical circuit, typically connected via a fused spur. They contain an electric heating element and can be switched on and off independently of your central heating.

Pros:

• Works year-round — Warm towels in every season
• Independent control — on/off, timer, or thermostat
• No plumbing connection needed — easier to install and position anywhere
• Essential for bathrooms without central heating access (external bathrooms, conversions)

Cons:

• Marginally higher running costs than central heating
• Requires a dedicated electrical connection (fused spur)
• Some models take longer to reach full temperature

Dual Fuel: The Best of Both Worlds

Dual fuel towel rails connect to both the central heating system and an electric element. When the heating is on, they work like a standard radiator. When the heating is off (summer), the electric element keeps them warm independently. It's the most versatile option, though slightly more expensive to install.

Our Recommendation

For most London bathroom renovations, we recommend electric towel rails with a built-in thermostat. The independence from the central heating system means warm towels 365 days a year, the installation is simpler, and the running cost is modest — typically 3-5p per hour for a standard-sized rail.
