Make Your Radiators Heat Up Faster With 1 Free Trick This Winter – The Clever Hack Pros Love That Cuts Heating Time in Half

Your radiators will feel hotter, too

If your radiators are slow to heat, but you have tried bleeding them and adjusting your thermostat, it might not be your heating system that's the problem, but the furniture placement nearby.

Poor air circulation results in sluggish radiator heating and a strained boiler. Luckily, it is simple and free to fix, say our experts.

Moving Furniture Away Will Make Your Radiators Heat Up Faster

When trying to keep a home warm without turning up the heat, clearing the area around your radiators is essential.

Phil Oliver, co-owner of Air Treatment Heating and Cooling, explains 'Radiators use convection to distribute warm air, so blocking that flow with furniture or curtains can drastically reduce their efficiency.

'If you have a radiator, I recommend keeping at least 12 to 18 inches of space between it and any large pieces of furniture, such as couches, beds, or shelving units. Maintaining this space around your radiator will produce a noticeable difference in how evenly and quickly your room heats up.'

For that reason, having a shelf over a radiator is often not a good idea, nor are radiator covers – even if they look nicer aesthetically.

It isn't just furniture that impacts how quickly your radiators warm up your room, adds Scott Levene, VP at Levco. Dust can also impede heating, with thick layers making your heating system work harder and possibly being the reason why your house smells musty.

Getting rid of dust regularly is easier with a radiator duster, from Walmart, which is designed specifically to fit between those awkward radiator panels and fins. It is the best tool for cleaning behind radiators without damaging your appliance or your wall, and negates the rust and mold risk associated with the viral hack of pouring water between your radiator panels to clear debris.

Similarly, it is best to avoid leaving curtains hanging over a radiator when in use, as this traps heat and redirects it to the glass, resulting in significant heat loss. Opting for blackout roman shades from Target can be a more convenient option for window treatment ideas above radiators.

Putting aluminum foil behind your radiators can also help to direct airflow into your room for more efficient heating. Phil explains, 'Radiator reflector panels or heat-reflective foil [available from Amazon] on the wall behind the radiator to help reduce heat loss.

'These inexpensive panels reflect heat into the room, rather than letting it escape through the wall, which allows the space to warm up faster and helps to keep a home warm all day.'

Investing in a smart thermostat, bleeding radiators, and checking the pressure settings on your boiler can also help to boost your radiator's efforts and heat your home more quickly.

In very old heating systems, it might be necessary to drain a radiator to remove sludge and boost efficiency. If you are not a fan of messy DIY, it might be time to call a pro for this task.

In the meantime, a stylish portable heater can help you zone-heat and reduce bills whilst staying cozy and warm at home this winter.
