Wattage measures your towel rail’s maximum power output. The wattage you’ll need depends on the size of your bathroom, the quality of its insulation and the location of your property.
You can use our radiator wattage calculator to work out what size wattage is needed to heat your bathroom.
If your towel rail will be the sole form of heating in your bathroom, you will need to choose a model with a wattage equal or greater to the wattage recommended by the calculator.
If you are combining your towel rail with other forms of bathroom heating, you will need to choose heating products which add up to the required wattage. Here are some examples:
- Russel is planning to heat his bathroom with underfloor heating and a towel rail. The bathroom needs 750 Watts of heating power, so he combines a 500w underfloor heating system with a 250w towel rail.
- Natalia wants to add a towel rail to a bathroom which already has a 400w central heating radiator. Her bathroom needs 950 Watts of heating power, so she plumps for a 600w towel radiator.
If in doubt, always choose a heater with a higher wattage. Under-specifying your heating will make your heaters work harder and less efficiently to warm the space. If you choose more powerful radiators fitted with thermostats, they will simply switch off when the room reaches temperature, using less power and operating more efficiently.
If your bathroom is already adequately heated and you just want a towel rail to dry your towels, the physical size of the towel radiator will be more important than the wattage.
Make sure you’ve accurately measured the space where you want to fit the towel rail. Always check the dimensions of individual products to ensure the towel rail will fit the space.
Most towel rails are long and vertical and usually require an empty stretch of wall. However, if you’re pushed for space you may want to consider a short, horizontal or ceiling mounted towel radiator which can be mounted above or below competing items of bathroom furniture.
How many towels will you want to hang on your towel rail? If you’re heating a busy family bathroom, you’ll want to choose a larger towel rail with curved rails that make it easier to hang a large collection of towels. If you’re heating an ensuite or private bathroom, a smaller towel rail should be sufficient.
Don’t forget to check the depth of your towel rail. In a small bathroom the depth of your towel rail can make a big difference, especially if it’s near a doorway. Curved bars can make it easier to hang towels but they will also intrude further into the room. For optimum space saving, choose a slimline towel radiator with straight bars.
