When buying bathroom heating, you must first calculate the required British Thermal Units (BTUs) to ensure the unit will actually heat your specific room size. Always opt for dual fuel towel rails if you want warm towels in the summer without turning on your central heating, and strictly measure your existing pipe centres before purchasing to avoid costly plumbing adjustments.
There is absolutely nothing worse than stepping out of a beautifully hot, relaxing shower into a freezing cold room. In the UK, getting your bathroom heating right is a survival necessity, not just a design choice. But with so many options on the market, from sleek matte black ladders to chunky cast-iron vintage styles, it is incredibly easy to buy a unit that looks fantastic but leaves you shivering.
To help you get it right the first time, here are the ultimate do's and don'ts for choosing the perfect heating solution for your washroom.
What is the difference between a bathroom radiator and a heated towel rail?
This is the most common question we get asked. The short answer is heat output. Traditional bathroom radiators are designed to heat the air in the room quickly and efficiently. A heated towel rail is primarily designed to warm and dry your towels. While a large towel rail will warm up a small en-suite, relying on a standard towel rail to heat a large family bathroom will usually leave the room feeling chilly.
The DO's of Buying Bathroom Heating
DO calculate your required BTUs
Never guess your heat output. BTU stands for British Thermal Unit, and it measures the amount of energy needed to heat your room. You need to calculate the volume of your bathroom (length x width x height), factor in your windows, and look at your insulation to find your target BTU. If you buy designer bathroom radiators that fall below this number, your room will stay cold, no matter how high you turn the dial.
DO consider a dual fuel option
If your heating runs off your main boiler, your bathroom radiators will be stone cold during the summer months when your central heating is switched off. This means damp, musty towels. Installing dual fuel towel rails solves this. They connect to both your central heating and your mains electricity. In winter, they run with your radiators; in summer, you just flick a switch to use the electric element.
DO add Thermostatic Radiator Valves (TRVs)
Don't just buy standard valves. Installing thermostatic radiator valves allows you to automatically control the temperature of the individual radiator. The valve senses the room temperature and adjusts the flow of hot water accordingly, keeping your bathroom comfortable while lowering your overall energy bills.
The DON'Ts of Buying Bathroom Heating
DON'T forget to check your pipe centres
If you are simply replacing an old radiator without lifting the floorboards, you must measure the distance between the two water pipes coming out of your floor or wall. This measurement is called the "pipe centre". Buying heated towel rails UK with matching pipe centres means your plumber can simply swap the old unit for the new one in minutes, saving you a small fortune in labor costs.
DON'T hang heavy models on weak walls
That heavy, traditional column radiator looks gorgeous, but it weighs an absolute ton once it is filled with water. Do not attempt to hang heavy radiators on standard plasterboard stud walls without reinforcing the wall behind it first. If you have weak walls, it is always safer to choose a floor-standing radiator instead.
DON'T cover your radiator in wet towels
This sounds counterintuitive, but if you buy a standard panel radiator to heat the room, throwing thick, wet towels entirely over it blocks the heat from circulating into the air. If you need to dry multiple towels and heat a large room, consider buying a radiator that comes with a specific overhanging towel bar attachment.
