Steel offers the lowest price tag compared to other materials, but it also offers the most diversity in terms of colour and style. Steel is malleable which allows radiators to be efficient because they can be physically designed to better pass heat from the water inside to the space around them (this is a radiator's job after all, despite some thinking that its job is to “store” heat). The heat output is also good, the proof is in the pudding with this one - would steel be the most common radiator material if the heat output was rubbish? Steel is a highly durable material which is important as radiators are going to be the victims of some knocks and bangs over time and you want them to withstand that.
StyleMost UK households tend to favour convector radiators, commonly known as panel radiators. In a type 33 convector radiator, the hot water from your boiler enters the radiator and fills the front and back panels, just like other radiators. But what makes these panel rads so efficient and effective in heating your home is the ‘fins’ – strip of metal shaped like multiple fins - that are attached to the front and back panel, like on a type 22, but on the type 33 there is another layer of fins and another panel! It is essentially a type 22 and type 11 combined together. The fins are heated at the same time as the main radiator panel, increasing the surface area of contact with the ambient air. As we all remember from school, this hot air rises, before eventually cooling, dropping back to floor level and being sucked up again by the convector radiator – leaving you with a cosy warm room!
ColourWhite is a true classic. Ideal for those who like to switch up their décor from time to time, a white radiator won’t restrict your interior design spirit. This gloss powder-coated finish is perfectly even and looks gorgeous with the simple wipe of a cloth. White can be perceived as boring or safe, but in reality, it gives a clean and fresh impression in your home. Plus, with our wide range of radiator valves and accessories, you can add a touch of colour to the radiator without it becoming overbearing within the room.
Heat SourceA central heating or hot water radiator is one that is plumbed into your homes central heating system. Whether you have a Combi boiler, gravity fed (conventional) system or a system with a cylinder, you can install this radiator.
AccessoriesThis radiator has G1/2” connections either side at the bottom and so the valves required will depend on your pipework (which is why they aren’t provided with the radiator):
- For pipework coming from the wall to the side of the radiator, use corner valves.
- For pipework coming from the floor and up to the side of the radiator, use angled valves.
- For pipework coming along the wall to meet the side of the radiator, use straight valves.
There are a few different types of valves available for you to choose from: Manual Valves provide easy on/off control – simply turn the valve by hand to allow the water from your central heating to pass through into the radiator or towel rail, just like a tap! If this radiator is going to be in the same room as your main boiler thermostat (usually a little box on the wall or the mantle, that you turn up and down) then we advise you to use manual valves over TRV’s because a TRV will conflict with your boiler thermostat and can cause temperature issues around the home. Thermostatic Valves (TRVs) provide multi temperature control of the radiators in your home – saving energy and money! These valves have sensor mechanisms inside that shut off the flow of hot water to the radiator when the room temperature reached the desired level! If your looking to reduce your carbon footprint while remaining cosy warm, then TRV’s are the way to go (provided they aren’t installed in the room where your main boiler thermostat is).

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.
