Frequently Asked Questions
What makes the Larkin Column Radiator different from other radiators
The Larkin Column Radiator is special because it mixes a classic traditional radiator look with modern power. Unlike flat panel radiators, it is built with three strong steel columns. This 3 column radiator design gives it a larger surface area to trap more cold air and turn it into warm air. It is made from heavy-gauge steel, which means it is built to last a long time and comes with a 10-year guarantee for your peace of mind.
How do I know what size radiator fits my room
You should never guess the size. The best way to get it right is to use our BTU calculator. This free tool asks about your room size and windows to give you a specific number called BTU (British Thermal Unit). This number tells you exactly how much heat output you need. Once you have this number, you can pick a Larkin radiator that matches it to ensure your room stays cozy and warm without wasting energy.
Is a 3 column radiator better than a 2 column one
Yes, if you need more heat. A 3 column radiator like the Larkin is thicker and has an extra row of tubes compared to a 2 column model. This extra row creates more surface area, which means it gives out higher heat output. It is the perfect choice for larger rooms or older houses that might be a bit drafty, as it provides a powerful punch of warmth.
Can I install these radiators on a plasterboard wall
You have to be careful because Larkin radiators are made of solid steel and are heavy. If you have a hollow plasterboard wall, we recommend using radiator feet to help support the weight. You should also find the wooden studs inside your wall to screw the brackets into. If you are unsure, it is always best to ask a professional installer to make sure your radiator installation is safe and secure.
What is the difference between single and double Larkin radiators
This refers to the number of sections joined together. A single radiator is slimmer and good for standard heating needs. A double radiator has two sets of columns back-to-back. The double version is thicker and produces almost twice the heat of the single one. Choose the double option if you have a big room but only a narrow wall space, so you can get maximum heat from a smaller spot.
Do these radiators come with valves included
No, the radiator valves are sold separately. This is actually a good thing because it lets you choose the style you like best. You can pick traditional crosshead valves to match the classic look of the radiator, or simple modern ones. We recommend adding them to your basket when you buy your radiator so you have everything you need for installation.
What are TRVs and should I use them
TRV stands for Thermostatic Radiator Valve. These are smart valves that let you control the temperature of each individual radiator. They sense the air temperature and turn the radiator down automatically when the room is warm enough. Using TRVs with your Larkin radiator makes your system more energy efficient and can help save you money on your heating bills.
Will a vertical radiator heat my room as well as a horizontal one
Yes, absolutely. A vertical radiator works just as well as a horizontal one. The main advantage of a vertical model is that it saves floor space. It takes up a tall, thin strip of your wall, leaving you more room for furniture. As long as the BTU output matches your room's needs, a tall Larkin radiator will keep you just as warm as a wide one.
Why is my new radiator cold at the bottom
If your radiator is hot at the top but cold at the bottom, it usually means there is "sludge" or dirt stuck inside. Because column radiators hold a lot of water, dirt from your heating system can settle at the bottom. The solution is to have a plumber flush your system to clean it out. Keeping your system clean helps your radiator work efficiently for years.
Why is my radiator cold at the top
If the top is cold but the bottom is hot, it means air is trapped inside. This is a very common problem. You can fix this easily by bleeding a radiator. You just need a radiator key to open the little valve at the top. You will hear a hissing sound as the air comes out. When water starts to trickle out, close it quickly. This lets the hot water fill the whole radiator again.
How do I clean inside the columns of the radiator
Dust can get trapped between the columns, but cleaning is simple. You can use a special long, thin brush called a radiator brush to slide between the tubes. If you do not have one, you can use a hair dryer to blow the dust out from the top, and then vacuum it up from the floor. Keeping it dust-free helps the heat flow better into your room.
Does the white finish change color over time
The Larkin comes in a high-quality white RAL 9016 finish. This is a powder coating that is baked onto the steel. It is very strong and designed not to peel or turn yellow like old paint used to. It stays bright and fresh for years, making it a great long-term choice for your home decoration.
Are these radiators compatible with my central heating system
Yes, the Larkin is designed to work with all standard UK central heating systems. Whether you have a gas boiler, a combi boiler, or a heat pump, these radiators will work perfectly. Just make sure to check the pipe connections, which are standard size, to ensure a smooth fit with your existing pipes.
Can I paint the radiator a different color
While the standard white looks great, we know some people want a unique look. You can order the Larkin in custom RAL colours or special finishes to match your room. If you want to paint it yourself later, you must use special heat-resistant radiator paint. Regular wall paint will peel off when the radiator gets hot.
Do I need wall stays for this radiator
Wall stays are metal arms that hold the radiator steady against the wall. Because column radiators are heavy and can be tall, we highly recommend using wall stays, especially for the tall vertical models or if you have children or pets. They prevent the radiator from being pulled forward or tipping over, keeping everyone safe.
How long does delivery take for Larkin radiators
We offer free delivery to the UK mainland. Since we stock many sizes of the Larkin in our warehouse, we can often ship them quickly. However, if you choose a custom color or a special finish, it might take a little longer to prepare. We always advise checking the specific delivery time on the product page before you book your plumber.
What happens if the radiator arrives damaged
We pack our products very carefully, but accidents can happen during shipping. If you notice any damage when your radiator arrives, please contact our support team at Budget Radiators immediately. We will help resolve the issue. It is important to check your items as soon as they are delivered and before you start any installation work.
Will this radiator help reduce my energy bills
The Larkin is designed to be energy efficient. Its steel columns heat up quickly and hold heat well. When paired with a good thermostatic valve, it stops your boiler from working too hard by turning off when the room is warm. Using the correct size radiator prevents energy waste, which is good for both the planet and your wallet.
Can I put this radiator in a bathroom
Yes, you can use the Larkin in a bathroom. It gives a lovely vintage look. However, bathrooms can be wet and humid. While the paint protects the steel, you should wipe down any water splashes to prevent rust over time. For very small bathrooms, you might want to check if you have enough space for the column depth compared to a flat towel rail.
What do I do if I hear a banging noise in the radiator
A banging noise usually means the pipes are expanding as they get hot, or the water flow is too fast. It can also happen if the radiator valves are installed the wrong way around. First, try bleeding the radiator to remove air. If the noise continues, you might need a plumber to check that your valves are on the correct pipes (flow and return).
