Alpha Anthracite 3 Column Radiator 300mm x 999mm – Horizontal Traditional Radiator
Product code: 20729
Material
Steel offers the lowest price tag compared to other materials, but it also provides the most diversity in terms of style. Steel is malleable, allowing radiators to be designed efficiently to transfer heat from the water inside to the surrounding space (this is the radiator’s job, despite some thinking it stores heat). The heat output is excellent — steel is the most common radiator material for good reason. It’s also highly durable, which is important as radiators can take knocks and bumps over time, so you want one that lasts.
Columns
“Column” refers to the radiator’s style, and the number in front (e.g., “3 Column”) indicates the number of vertical tubes in each section. These tubes are connected at the top and bottom. A 3 column (also called triple column) radiator has three vertical tubes per section. Compared to slimmer 2 column models, the 3 column offers greater depth and heat output, making it ideal for heating larger rooms effectively.
ColourAnthracite is a high-end variety of coal noted for the purity of its carbon and the dark grey smoke it emits when burning. It’s also one of our customers’ most popular picks for a modern-looking radiator that looks as good as it functions. The smoky matt finish you achieve with this colour is quite unlike any other and produces a stylish effect with even the most minimalist design. As we become more conscious of our surroundings, tastes shift from the functional and the merely decorative to something combining qualities of both, and anthracite radiators certainly tick all of the boxes.
Heat Source
This central heating or hot water radiator connects directly to your home’s central heating system. Whether you have a Combi boiler, gravity-fed (conventional) system, or a system with a cylinder, this radiator can be installed to provide reliable heat.
Accessories
This radiator has G1/2” connections on either side at the bottom, so the valves you need will depend on your pipework (valves are not included):
For pipework coming from the wall to the radiator’s side, use corner valves.
For pipework coming from the floor up to the radiator’s side, use angled valves.
For pipework running along the wall to the radiator’s side, use straight valves.
Wall mounting brackets are included. Column radiator feet aren’t necessary but can enhance the traditional look. If desired, you can use the feet alongside wall brackets to better support the radiator’s weight. Alternatively, skip the wall brackets and install wall stays in matching or contrasting colours.
Valve options include:
Manual Valves: Easy on/off control by hand, ideal if the radiator is in the same room as your main boiler thermostat (to avoid temperature conflicts).
Thermostatic Radiator Valves (TRVs): Allow individual temperature control, saving energy and money by shutting off water flow when the desired room temperature is reached. Best used in rooms without the main boiler thermostat.

Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas or oil boiler with a flow temperature of around 75°C and a return temperature of around 65°C.
- Δ30 = Low temperature systems e.g heat pumps.
