Making the switch from panel radiators to cast iron radiators is a serious style upgrade – but a sleek new look for your home isn’t all you can expect. From improved efficiency to taming those energy bills, there are plenty of perks associated with making the switch.

Expect an adjustment period as you get used to your new radiators, including learning how to make them as efficient as possible. There are a few key differences in how they work, which means you’ll need to make the most of thermostatic valves and your home thermostat to reap all of the benefits. Here’s everything you can expect when you make the switch to cast iron radiators.

The Enduring Appeal Of Cast Iron

Cast iron radiators offer a glimpse into the past, as this is the first mass-produced central heating system that was available during Victorian times. Thankfully, modern cast iron radiators have been significantly updated and improved since the days of steam central heating.

Modern central heating systems allow you to enjoy the warmth of cast iron, with all of the efficiency of thermostatic valves, smart thermostats and efficient boilers.

Ripping out our steel panel radiators and upgrading to beautiful cast iron is so much more than a style statement for your home. It’s an investment in comfort and efficiency for years to come.

What to Expect When You Upgrade To Cast Iron Radiators

You’ve spent hours choosing the perfect style, colour and size for your home. The day has finally arrived – your radiators are finally getting installed. Here’s what you can expect in the days/months/years after installation…

1. They take ever so slightly longer to warm up

Cast iron has a lower thermal conductivity than steel, which means it takes ever so slightly longer to heat up than steel panel radiators. But, once it has reached temperature, it holds on to the heat for much longer. This means that your radiators will stay warm long after you have switched off your central heating – bonus!

To adapt to this, we recommend adding thermostatic valves to take the guesswork out of controlling your central heating. Thermostatic valves help to drive down energy bills by switching off your radiators once they have reached the desired heat output.

These valves work in harmony with your central thermostat, which controls on/off operation for your entire system. All of this adds up to big savings, as you’ll only have your heating switched on when you need it.

2. Comfortable, stable temperature

You might be accustomed to turning on your heating, it quickly heats up, your room becomes sweltering and you have to open a window to cool it down. This is a common routine with panel radiators, but it will quickly become a thing of the past with your cast iron radiators.

Cast iron heats up gradually and then holds a steady and comfortable temperature. This means fewer temperature spikes and a comfortable, ambient room temperature – at last!

3. Fewer airborne allergens

A surprising benefit of cast iron radiators is their impact on air circulation. Since they radiate heat rather than relying on convection currents, they don’t cause turbulent air currents like some fan-powdered radiators. This means fewer allergens circulating in your home.

When paired with regular dusting and cleaning, this can be a huge relief for those living with allergies. Cast iron radiators are much easier to keep clean, as they are free-standing instead of wall-mounted. This means that you won’t have dust build-up behind your radiators.

4. Improved boiler health

One of the perks of well-maintained cast iron radiators is the positive impact on your boiler health. Heating to steady and stable temperatures will keep your home comfortable without the need for intensive cycles of boiler use. This is particularly true when you have an efficient timer and thermostats on individual radiators.

When paired with regular boiler maintenance, your cast iron radiators will work efficiently year after year, ensuring your home remains comfortable and warm.

5. Radiator envy from all of your friends and family

Cast iron radiators are a statement in any room, and you can expect your visitors to take note. They offer a beautiful and stylish upgrade from the usual wall-mounted panel radiators. They certainly look the part in a period property and could be ideal as a secondary heat source alongside a wood-burning stove.

6. Increase your home value

Cast iron radiators are not just an investment in your comfort levels – they can also increase the value of the home. Well-maintained cast iron radiators are a welcome sight for many house hunters, and they certainly add to the character of a period property.

Since cast iron radiators are built to last, you can pass on these benefits if you decide to sell your home.
