Three Benefits of an Oil Filled Radiator

Last updated: May 2024

What comes to mind when you think of an oil filled radiator? Is it a faithful, portable standby when your central heating breaks down? Perhaps a sleek and stylish wall mounted solution with the very latest technology? Oil filled electric radiators encompass a wide range of styles, but they all have one thing in common: they’re popular, sought-after solutions for home heating. There’s a reason why they’re among the most widely purchased electric heaters, so if you’re not sure what they can do for you, here are the three main benefits of oil filled electric radiators.

1. They have excellent thermal retention

No matter what style of oil filled radiator you’re most familiar with, you’ll find they’re all designed to heat using the same basic principle. These radiators warm up an engineered thermal fluid or oil within the housing, transferring heat out into the room and warming the surrounding air. If you’re thinking it’ll take longer to heat up a mass of liquid compared to a wire element, you’d be right, but the oil in these radiators does provide an additional benefit.

Long-lasting warmth

Oil filled radiators are excellent at retaining heat, so less energy is needed to top up temperatures in your space. Even after they’ve stopped drawing power from the wall, these radiators will continue to gently radiate heat and keep you comfortable because the fluid inside is designed to cool slowly. Their longer heat up times aren’t to everyone’s taste – in which case we recommend a dry thermal radiator such as the Haverland RC Wave – but they’re a great choice if you want better heat retention. Compared to fan heaters which are noisy, inefficient and can give off an unpleasant smell, oil filled radiators create a lasting, comfortable warmth that can be enjoyed over longer periods.

The superior thermal properties of oil filled radiators means they’re able to retain heat for longer, so you can enjoy prolonged comfort without worrying about energy waste.

2. They have lower running costs

In practical terms, the improved heat retention of oil means that your electric radiators will be more energy efficient and ultimately cost less to run. However, there’s more to it than that.  

24/7 programming

If you’re using fixed radiators with advanced digital programming, you can slim down your bills even further by creating a heating schedule for every area of the house. Controls are built into each unit, so you’re given the scope to create a bespoke heating routine for each room, matching how it’s used on a daily basis.

Did you know?

Zoning your heating is one of the best ways to save money.

100% efficiency

As with all electric radiators, oil-filled radiators are 100% efficient at point of use. This is because they convert every watt of electricity used into heat, ensuring nothing is lost along the way. As a result, you don’t end up paying for wasted warmth and instead know exactly where your money is going.

It’s the heat-retentive properties of oil in conjunction with accurate digital thermostats that makes oil filled radiators so cost-effective as a home heating solution.

Precision digital thermostats

Fixed oil filled electric radiators also come with precision digital thermostats – many of which are accurate to within 0.2 or 0.5 °C – which prevents your space from being overheated. By having a precision thermostat on each radiator, as opposed to one thermostat for your whole heating system, you’ve got a greater say on how much energy you use to heat your home. It’s the heat-retentive properties of oil in conjunction with accurate digital thermostats that makes oil filled radiators so cost-effective as a home heating solution.

Not only are they 100% efficient at point of use, oil filled radiators are in-built with a range of features to help you keep your energy bills down.

3. They offer convenient control

Oil filled electric radiators really do offer something for everyone, whether you just want a backup heater for emergencies, or an energy-efficient system you can rely on day to day. You may want basic manual control or advanced programming. Whatever the case, we’re certain there’s an oil-filled electric radiator to suit your needs.
