Sherwood - Anthracite Vertical Round Top Column Radiator H1800mm x W507mm 2 Column
Product code: 20777
Material
Steel is the most affordable radiator material and offers great versatility in style and colour. Its malleability allows manufacturers to shape radiators for maximum heat transfer from the water inside to the room. Steel’s efficient heat output makes it the top choice for most homes. It’s also very tough, capable of handling bumps and knocks over years of use without damage.
Columns
The term “Column” refers to the radiator’s design style. The number before it, like “2 Column,” indicates how many vertical tubes each section has. These tubes run top to bottom and are connected at both ends. A 2 column radiator, sometimes called a double column, is the slimmest option available. While it produces less heat than larger 3 or 4 column models, it’s ideal for smaller spaces where compact warmth is needed.
Colour
Anthracite 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 radiator is designed to connect to your home’s central heating system. Compatible with Combi boilers, gravity-fed setups, or systems with cylinders, it delivers consistent heat through hot water circulation.
Accessories
The radiator features G1/2” connections at the bottom on each side. The valves you need depend on your pipe layout (valves not included):
-
For pipes coming from the wall to the radiator’s side, use corner valves.
-
For pipes running from the floor to the radiator’s side, use angled valves.
-
For pipes along the wall connecting to the side, use straight valves.
Valve types:
-
Manual Valves: Simple to operate by hand, recommended if the radiator shares a room with your boiler thermostat to prevent temperature conflicts.
-
Thermostatic Radiator Valves (TRVs): Automatically control radiator temperature, saving energy by shutting off when the room reaches the set temperature. Best used in rooms without the 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.
