Tucking curtains behind radiators prevents heat loss through the window. However, interior and heating experts generally advise against this. It reduces room circulation and can damage fabric, so it's best to hem curtains above the heater or use tie-backs when the heat is on.
It is not a good idea to tuck curtains behind radiators when the heating is switched on. The typically thick fabric that is used in the makeup of curtains will cause panel blockages at the back and sides.
If you're in the market for new curtains (or are handy with a needle and thread) consider shortening them so that they sit just above the radiator. Ideally, the hem should be around 2–4 cm above the top of the radiator. This creates a gap for warm air to escape and keeps your home warmer.
Curtains should hang so that the hem ends at least 2 inches (5 cm) above the top of the radiator. Never allow curtains to drape directly over or tuck behind a running radiator. Covering the heater traps warm air, decreases heating efficiency, and can damage your curtain fabric.
Curtains can safely go over radiators, but they shouldn't touch them directly. Most modern radiators don't get hot enough to ignite fabrics, but prolonged exposure to heat can damage certain materials or cause discolouration.
Do Scandinavian Homes Have Curtains? True homes in Scandinavian countries typically don't have curtains. This is for a couple functional reasons. First, having no curtains allows maximum sunlight to enter the room, and when you're as far north as Scandinavian countries, sunlight is at a premium.
Curtain trends in 2026 are shifting from purely functional covers to architectural statement pieces. The top looks emphasize rich, natural textures, layered depth, warm neutral and earth-toned palettes, and smart home integration to bring quiet luxury and character to interior spaces.
The best tool for painting behind a radiator is a long-handled brush or a mini roller with an extended arm. These tools are specifically designed to reach narrow, awkward spaces without having to remove the radiator.
What clearances do I need above and below my radiators to ensure maximum efficiency? For the most effective and efficient distribution of heat, BestHeating would recommend leaving a clearance of 50mm above, and 100mm below your radiators.
The short answer is yes. High-quality blackout curtains can reduce the amount of heat entering a room by up to 24-33% depending on the fit.
If you use curtains or blinds to keep a room warm, a radiator under the window can work against you. When drawn, thick curtains trap heat between the fabric and the window, preventing it from circulating into the room effectively.
Contemporary Radiator Covers
If you're looking for something a bit more modern, then worry not as there are plenty of sleek and stylish radiator covers available. From bold black and anthracite to soft greys, all in a range of designs, including adjustable options and those with storage.
"Things like a sofa or a chest of drawers pushed right against a radiator can block the heat from coming into the room, meaning you're spending a lot of money to heat the back of them.
Ideally, short curtains are more suitable over a radiator than floor length. Whether you have a double or single panel radiator, the bottom of the curtains should sit at least 2 – 4 cm above the top of the radiator.
Radiator covers are not inherently a fire hazard. Hydronic or steam radiators typically run between 180∘F and 220∘F, which is well below the ignition point of wood (around 900∘F or higher). However, they do pose risks if they are poorly ventilated, placed on electric heaters, or made of cheap materials.
Most radiators last between 8 and 10 years, depending on the vehicle and how it is driven. A Lincoln Navigator used for towing in hot weather will place greater demand on its cooling system than a Corsair used primarily in daily commuting.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
According to energy pro Matt Oberle, all you need to do is move your sofa 12 inches away from the radiator. “You don't need to redesign the entire room,” Matt, from Utility Rates, explained. “Moving it 30 or 40 centimetres away (12 inches) is usually enough to restore proper circulation.
Windows, being a common source of heat loss, can create temperature variations within a room. As hot air rises, placing radiators under windows means that the heat emitted rises to counteract the downward draft of cold air. This is an attempt to maintain a consistent and comfortable temperature in the room.
By fitting reflective foil behind your radiator, you can reflect warmth back into the room and help prevent cold draughts from entering through the wall.
How do I avoid streaks or uneven paint behind a radiator? Use a consistent stroke pattern (usually vertical). Apply even pressure with your brush or roller. Avoid overloading your brush with paint to prevent drips.
Heat Distribution Limitations
While vertical radiators are great for warming rooms, their heat distribution can be less even than horizontal models. The heat tends to rise more directly, which could leave certain areas of the room feeling cooler, particularly in spaces with low ceilings.
Some of Stewart's homes utilize interior blinds for light regulation and privacy. Others feature windows framed by exterior shutters, operable versions of which can also be used for light control, ventilation and privacy.
